Making 3D prints with OpenSCAD, Poser and Shapeways.

As you might know, I’ve played for years with Poser Pro now. And for about a year, I have created printed models through the services of Shapeways while also creating all kind of artwork with those Poser models and E-ON Vue. But more recently (well, less than a week ago) I started experimenting with OpenSCAD, which is an open-source CAD application where you just “program” a special script file and it will generate a 3D model for you based on that script.

So, to start I will show you how I created a special box for my electronic experiments, which is my Shapeways model. It is a rectangular box with five holes in the side for wires that lead to a small, round container. Not sure what I want to build inside it, but I just like the shape and it is a nice experiment to start with.

This is a box with two different lids. One round, one rectangular. The rectangular lid will also contain a small engraved text.

To start, I create a simple module to create the lid:

module BoxLid(width, height, depth, groove){
        cube([width, height, depth/3]); 
        translate([groove, 0, depth*1/3])cube([width-2*groove, height-2*groove, depth*1/3]);
        translate([groove/2, 0, depth*2/3]) cube([width-groove, height-groove, depth*1/3]);
        translate([width*6/20, groove*1, -depth*1/3]) cube([width*8/20, groove/2, depth*1/3]);
        translate([width*7/20, groove*2, -depth*1/3]) cube([width*6/20, groove/2, depth*1/3]);
        translate([width*8/20, groove*3, -depth*1/3]) cube([width*4/20, groove/2, depth*1/3]);

This set of cubes will create the lid that will slide in a special slot that we will add to the box. The first three cubes are of various sizes and create a groove to slide over. The lid will completely cover the side of the box.

The last cubes are used to put some relief on the lid to allow it to slide easier up and down. But I want to have it engraved with some text, so I create an engraving module:

module label(name, depth, fontSize){
    linear_extrude(height = depth) {
         text(name, size = fontSize, font = "Lucida Calligraphy", halign = "center", valign = "center", $fn = 50);

And I need a second module for the lid including the engraved name:

module NamedBoxLid(width, height, depth, groove){
         BoxLid(width, height, groove, groove);
         translate([width/2, height/2, groove/2]) rotate([0, 180, 270]) label("Team Katje", groove, 8);

Yeah, engraving is just that simple! Subtract the shape of the text from the shape of the lid. The most tricky part is actually trying to rotate it and making it fit. But it also tells us how we can create a box. We basically make a box and subtract the lid from it! I will also subtract 6 cylinders from a side for the holes to the round box on the side. And we will also subtract the inner space from the box so it has space:

module Box(width, height, depth, groove){
         cube([width, height, depth]);
             translate([groove, groove, groove]) cube([width-2*groove, height-2*groove, depth-2*groove]);
             translate([width*1/5, groove*3/2, depth/2]) rotate([90, 0, 0]) cylinder(h=groove*2, r=groove*2, $fn=precision);
             translate([width*4/5, groove*3/2, depth/2]) rotate([90, 0, 0]) cylinder(h=groove*2, r=groove*2, $fn=precision);
             translate([width/2, groove*3/2, depth*1/5]) rotate([90, 0, 0]) cylinder(h=groove*2, r=groove*2, $fn=precision);
             translate([width/2, groove*3/2, depth*4/5]) rotate([90, 0, 0]) cylinder(h=groove*2, r=groove*2, $fn=precision);
             translate([width/2, groove*3/2, depth/2]) rotate([90, 0, 0]) cylinder(h=groove*2, r=groove*2, $fn=precision);
             BoxLid(width, height, groove, groove); 

Or actually, I combine the five holes, the box content and the lid together into a single shape and subtract the whole shape from the box. This way, I know the lid will fit perfectly on the box.

All I have to do now is create the second, cylindrical box on top of the holes. For this, I again start with creating a lid:

module CylinderLid(width, groove){
         cylinder(h=groove, r=(width-groove*2)/2, $fn=precision);
        translate([0, 0, groove])
             cylinder(h=groove, r=(width-groove*2)/2-groove, $fn=precision);
             cylinder(h=groove, r=(width-groove*2)/2-groove*2, $fn=precision);

Again, a simple procedure of stacking two cylinders on top of each other. However, to make slightly more room, the smaller cylinder is hollowed by subtracting an even smaller cylinder. The result is a ridge to keep the lid in place.

And like the box, I will subtract the cylinder lid from a hollowed cylinder:

module CylinderBox(width, height, groove){
         cylinder(h=height, r=(width-groove*2)/2, $fn=precision);
                 CylinderLid(width, groove);
                 translate([0, 0, groove]) cylinder(h=height-groove, r=(width-groove*2)/2-groove, $fn=precision);

Now I know that the cylinder plus lid will be exactly the proper height together. All I have to do now is put them all together:


Box(width, height, depth, groove);
translate([0, 0, depth+3]) NamedBoxLid(width, height, depth, groove);
translate([width/2, groove, depth/2]) rotate([90, 0, 0]) CylinderBox(width, cylinderhight, groove);
translate([width/2, height/2, depth+10]) rotate([180, 0, 0]) CylinderLid(width, groove);
translate([width/2, height/2, depth]) cylinder(h=10, r=1, $fn=precision);

I first specify the sizes for the box in millimeters. It will be 4x4x9.2 CM in size, which is large enough for a 9 volt battery plus holder, some wires and maybe some other stuff.

Next, I create the box at the standard location. Above the box, I put the lid, with some space in-between to keep them separate. The cylinder is put against the box itself around the holes but the lid for the cylinder is put on top of the lid for the box itself.

The last thing connects the box and the two lids to make it all a single part. On Shapeways, you have to pay extra if it is all separate parts so make sure you connect it all together with thin connectors that you can easily cut away with a sharp knife. And yes, I checked to make sure it doesn’t go through the line of text on the lid!

Now, what does it all look like? Well, just look at these images:

It is all quite easy to do, although it requires plenty of math to get things in the proper locations. I haven’t explained the math part and I won’t. I’m just showing what you can do with OpenSCAD and a few hours of free time.

The result is a .STL file that you can upload to Shapeways to have it printed. As an alternative option, you can also convert it to an .OBJ file format and import the box into Poser, and add a Poser model on top of the cylinder lid, just for fun.

Or you will add textures to the shape and use it in Poser/Vue to create some new image. It can be even more interesting if you can combine a 3D printed model together with a rendered image of the same model.

I still have a lot to learn about OpenSCAD but this tool allows you to specify exactly the shapes that you want for your 3D model and allows you to create modules that will allow you to do some complex things like separating a lid from a box.

Making a hollow model for Shapeways.

I like Shapeways! You can use them to generate prints from 3D models that you design. However, at first I wanted to create 3D models with some extra hollow closet or whatever else to use for some small electronics. Problem is, these adages will also add more material and space, thus increase the price. So I decided to just create hollow busts from my model so I still have some hollow area but also a nice model without any other props.

To start, I use a few pieces of software. First of all, Poser Pro with more models. Although a little old already, I still prefer to use the Victoria 4 model from DAZ3D. With some extra shapes and textures, you can make some very beautiful models.

Next, I need a tool for handling and converting the 3D models. Here Accutrans 3D does a lot of magic for me, including minor fixes and allowing me to fix any textures. It also allows me to merge parts that use the same texture, which makes everything a lot simpler.

I use Netfabb for repairs, scaling and to cut the model in half, so I get a bust instead of a whole model. The free version is good enough for my purposes.

And I use Meshmixer to make the bust hollow and thus reduce the amount of material required.

So I start with creating a model and putting her in a proper pose for my bust. Poser can do that real fast and, what the heck, let’s keep her topless! I just want a simple example. And when the pose is done, I need to save it three times! First, I save the original pose as a Poser file. That way, I can make adjustments to the pose later on. Second, I do an export to the Collada file (.dae) format. Poser doesn’t do a good Collada-export, though, but it will copy all the used textures to my save folder, in a subfolder called textures! And I need those copies later on. The third file is a Wavefront file (.obj) which I will import in the next tool, after I copied the textures from the subfolder to the save folder.


So, this is what Abby will look like. Even though she is topless, I just kept the “naughty parts” hidden for my blog.

A few notes: Abby is a female Elf and I have used her for several CGI images already. I have never used her for a print, though. This will be interesting because her hair might not print as well as I hope, but this is all just a test.

Keep in mind that Shapeways has a Content Policy that is a bit strict when models are nude. Nudity is allowed as long as it is artistic by nature. However, the definition of “artistic” is up to the person reviewing the model and chances are that your model will be refused because they don’t think it is artistic enough.

Now I will have to merge the various parts for this model and maybe remove a few things that disturb my model. To begin with, my model will have a layer called “Cornea” and one called “EyeSurface”. Normally in Poser, those would be transparent and thus not visible, except for some extra shininess or added reflections. Unfortunately, they became visible in my model so I generally remove these layers. Also, there are “Eyelashes” that generally either lack a texture or are just completely black. I remove those too, in general.

Once done, I use “Tools_1/Merge layers with same materials” to reduce the number of layers in my model. Then I save it to a new folder in two different formats. First of all, Collada, so I have a copy that I can use for this model. Next, a Wavefront file for further processing.

The next step is scaling and the first cut. Netfabb does a great job at this, keeping the textures intact!

Screenshot 2015-11-13 18.22.17Screenshot 2015-11-13 18.23.43

As you can see, the complete model is naked, but that’s not a big problem. The bottom half will be cut away anyways. But first some scaling. The Y size is the largest value at 0.57 mm, which is very, very small. I’ll change it to 600, making the model about 60 CM high. I will then export the file to a new folder in Wavefront format again, and it will be saved including new texture files.

Now, I will make her hollow by using Meshmixer. Basically import the Wavefront file that Netfabb created and choose “Edit”Hollow” and the system will generate a hollow space inside your model.

Screenshot 2015-11-13 18.41.36

Once you like the hollow area, accept it and export it to another new folder as Wavefront format. Because now we will have to make a cut! So we have to import the file in Netfabb again. And do a cut!

Screenshot 2015-11-13 18.47.59

Although we’re only interested in the top half, I generally rename both parts (e.g. “Abby Top” and “Abby bottom”) so I can always decide to have both sides printed! With some glue, you can glue them together again.

But what does the result look like?

Screenshot 2015-11-13 19.12.29Screenshot 2015-11-13 19.30.28

I’m a bit annoyed that the textures weren’t saved after I made the cut. Then again, I would like the print to be in white plastic anyways. The colored sandstone would not be strong enough to hold the thin walls and the colored plastic has a size limitation, which is a bit small to me. So this last white result is fine. I also show the bottom half but Shapeways will have some minor troubles with that part. The arm is not connected to the rest of the body so it would become two parts.

And the bottom part is nude, thus a possible content policy violation.

The last step is the upload to Shapeways. This is a bit slow but since I kept the model reasonable simple, I should have a result within a few minutes. In the meantime, do keep in mind that Shapeways will charge for the amount of machine space and not just material space when printing in white plastic. Thus, while the hollow model will require less material, you will still have to pay for the large size. And since the original size resulted in a print of $400, I reduced the size by 60% on Shapeways, which reduced mostly the amount of machine space. The price is now around the $100, which is still a lot. But hey! I have a hollow model now.

I could also upload the bottom part, reduce it by 60% and have both parts printed to get a complete model, which I have to glue together. But once I do that, I will likely use a nicer model instead. For now, I’m still doing a lot of experiments and I try to avoid printing a lot of them, since these prints are expensive.

The final result.


So, what does the final result look like?

As you can see, the model is about as large as my cup of tea. I can insert an RGB-led inside it to make a very colorful display. Not all parts are hollow, though. Her right arm is solid from slightly above the elbow. Also, I kept her mouth and teeth part of the model, so they became part of the solid areas too. So yeah, her teeth are printed too but you can’t see them. And the skullcap and hair was also made one solid piece though her head, as part of the auto-repair or whatever. This makes her top a bit heavy but it is still stable enough to stand.

I also learned that scaling and cutting a model can be done from Meshmixer quite well and that too gives great results. With Meshmixer you can also add holes to a hollow model so you don’t have to cut it in two parts. The small hollow spaces would allow the unused material inside the model to fall out. But then you will have a model with small holes in it.

As I have been experimenting with these pieces of software, I’ve learned that Netfabb has a great repair function similar to what Shapeways uses. All three apps together make some pretty powerful tools for anyone who wants to create 3D models to print.

Four models on Shapeways (NSFW)

I like Shapeways since you can upload your own 3D designs and end up with a 3D printed model. This allows me to e.g. create custom boxes for small hardware experiments. These boxes are combined with my Poser models and will thus result in very interesting designs. But like everything with 3D, you will have to do some experiments first. I created three new models in Poser named Nora, Tommi and Cassiopa and I used some interesting trick to create a special rack to include in the pose. But first, let’s look at Nora:

WIN_20151026_102324 WIN_20151026_102455

Nora was printed in two versions: White plastic and Colored sandstone. And in both models a few flaws were already visible. Nora’s shoes were made of a very thin material and the upload to Shapeways did a repair that removed the very thin parts. As a result, the shoes are flawed.

WIN_20151026_102331 WIN_20151026_102500

Well, a bit of glue and plastic can fix that. But her fingers were also a bit delicate and the sandstone version ended up with broken fingers because the fingers are actually too thin. Again, some glue and they’re back in place.

WIN_20151026_102352 WIN_20151026_102505

Her thumb is still missing, though. Then again, I was more interested in checking how well the 3D printer handles holes, like the area where she keeps her left hand. In front of her genitals, to keep it decent, yet far away so it doesn’t touch. Combined with the position of her legs, this results in a complex hole to print but it ended up flawless. Even her left hand was intact.

WIN_20151026_102409 WIN_20151026_102511

So, what I’ve learned from Nora is that thin elements like fingers and shoes won’t print very well. White plastic does a better job than sandstone, though. That’s because sandstone needs further processing after the printing is done, which requires some manual labour. Thus, small parts can end up being damaged.

Another part that’s important with the sandstone version is the textures. For this, I will check her face:

WIN_20151026_102344 WIN_20151026_102524

And in case you’re wondering why her hair is covered by a towel, well… Hair really doesn’t print very well. It tends to generate loose shells or often to parts that are too thin to print. Besides, the towel makes her look as if she’s just out of bath, relaxing.

The White plastic versions shows a reasonable amount of details in her face. Even her open mouth is printed quite nicely. The sandstone model also has an open mouth and you might see her tongue and teeth if you look inside with a microscope. But I’m more looking at her face and eyes.

Printing in colored sandstone has an ink density of about 50 DPI. Normally, a printer would print at 300 DPI so the colors will lose details. But I chose a light-colored iris and Nora has good-looking pupils in this print. Which is important to remember, since dark eye colors might darken the whole eye. It still looks good in my opinion. At least better than what I can do with paint and a brush.

The next model is Cassiopa. Since I know that thin parts won’t print well, I’ve placed her on a towel, hoping for a better result. The result is okay but the sandstone version did not survive the print because the towel was too thin. So I uploaded a newer version of Cassiopa on a more solid floor and in this version, I also adjusted her clothing. Why? Because I need to test more than just panties on topless women. Still, the white plastic version looks okay, although it is a bit small:

WIN_20151026_102632 WIN_20151026_102652 WIN_20151026_102700 WIN_20151026_102817

The model was almost 15 CM long, but that’s the length of the towel. Cassiopa uses only 2/3rd of this length, thus she’s smaller than my other models. (This also happens with one of my Tommi models.) Smaller means that fewer details will be visible but it is still detailed enough.

The towel she’s on has a hole in it, which is too bad but I’m not too worried about it. I now know that I can’t use these kinds of thin plateaus for my models to rest upon. In the sandstone version, the towel had crumbled away.

The last model is Tommi which I’ve combined with a rack. I made a second version of Tommi climbing this rack but Tommi herself becomes small if you do this, thus losing details. Let’s look at the climbing version first:

WIN_20151026_103142 WIN_20151026_103151 WIN_20151026_103216 WIN_20151026_103233 WIN_20151026_103242 WIN_20151026_103256

I gave Tommi a skirt instead of panties so you should have been able to look up her skirt. However, Shapeways repairs this automatically and as a result, the skirt became solid. And that’s a flaw in the skirt model.

This is a colored print so her texture helps to add details, but she’s too small to be very clear in details. She did have a flaw in her right hand, since her fingers were too thin and either did not get printed or broke off afterwards. A bit of paint will fix that, though. It is just something to remember.

So, remember: make sure thin parts are well-supported and preferably resting against something else and with clothes, be aware that Shapeways might fill in specific areas that you’ve hoped would stay hollow. In this case her skirt but I also tried another interesting top on Tommi but that added a white mass over her breasts since Shapeways was filling the area between the left and right cup.

Next, the bigger version of Tommi with her resting upon the rack. That one was perfect, although one of the legs from the rack had broken off during transport. So, even if a part is thick enough to print, it might still be very vulnerable. With a length of over 4 CM, they can’t handle a lot of stress. Still, this model is great with no broken appendices and even her toenails are visible!

WIN_20151026_102904 WIN_20151026_102914 WIN_20151026_102958 WIN_20151026_103102

Well, at least I glued the leg back in place. I might decide to remove all four instead, though, if I fear they will break again. This model happens to be quite heavy too, which makes sense since she has the biggest volume of all. Her eyes are nicely detailed and her skin color even has some variation around her knees. And you can see her toenails! A bigger model is nice in that regard so if your model has a lot of fine details, have it printed in a larger scale! Although the price will scale up too, since more materials will be required.

Well, these three models all look reasonable well and taught me what I need to know about printing Poser models: use a reasonable large-scale, support all small parts and be aware that hollow spaces might end up being filled with extra material because Shapeways “repairs” some thin materials.

I kept these models mostly undressed because I know the textures of these models and needed to see how the color printing will support the texture details. Also, it is difficult to find Poser clothing models that are working well when uploaded to Shapeways. These models are not made to be printed in 3D but to be rendered. So finding good clothes to print is difficult. For Victoria 4, her bikini top and bottom do print quite well, though. They too are filled up, but the filling it towards the body of the model and not between both cups.

Another problem is the limitations on models set by Shapeways. There’s a size limit and there’s a polygon limit. (64 MB or 1 million polygons.) Poser models can easily go over this amount of polygons so you will have to find a way to reduce those, while keeping textures intact.

And then there’s the rack used by both models. The rack is the same length for both and I’ve created it myself by using the Firestorm viewer with the Second Life virtual worlds, but I could have used my own OpenSim world too. I just joined several cylinders for the rounded sides and balls for the rounded corners to build the framework. I also created a square plane with a hole inside, which I copied three times and put next to one another. I then exported the whole model from the SL viewer to a Collada file, which I imported in AccuTrans 3D to clean it up a bit and to reduce the complexity of it. (For example, by merging all parts into one single part.)

And then I checked if the rack has enough space for other hardware.

WIN_20151026_104131 WIN_20151026_104323

Well, the rack isn’t wide enough for an Arduino board

Since I copied the square plane three times, I had expected all holes to have the same size. And the rack was made so I can add some hardware in the empty rack space and have some wires or other parts move through the open holes to e.g. shine a LED light on the model. So, I was surprised when I discovered that the middle hole was slightly bigger than the other two. Which I discovered by trying to fit an Arduino-board. (The YUN is shown in the picture.) The length is long enough for the Arduino Mega but it will have a few millimeters on the sides of the rack. The pins are actually at the exact location of the long bars. So you could actually put an Arduino in the rack if you don’t mind the width.

But smaller devices like the Arduino Mini, the Trinket, the NetDuino mini and the Digispark have plenty of room inside the rack.

But back to the holes!

WIN_20151026_103544WIN_20151026_103535 WIN_20151026_103705 WIN_20151026_103853 WIN_20151026_103920 WIN_20151026_104434

Using the climbing Tommi version, I used to try a green LED. It doesn’t fit the top or bottom hole but it does fit the middle hole. Trying it again with a regular lamp of 5 MM diameter, I see it going through the middle hole without effort but the top and bottom ones don’t fit. A laser light won’t even fit the middle hole, though.

The conclusion is that these holes are a bit too small for LED lights. No problem, since I can take a drill bit and make them wider. Still, I had hoped they would be big enough for a LED light. So I have to redo my calculations. And I have to wonder why the middle hole is bigger than the other two, while they’re basically all the same in my 3D software.

Anyway, I now have two great models for containing some of my experimental hardware. I know the racks are open so the hardware would be exposed but that’s something I will solve with a next version of my rack. I also know how thin the walls can be and how thin the walls of my rack are. I can still have the rounded areas but the rack should get more solid walls. Thin walls too, since the rack has a lot of volume.

Next, the question what I would like to create with these models. Whatever I think of should match the model. The three holes in the rack are meant for lights, cables, buttons or something else but I don’t want to show too much hardware on the model side of the rack. I also need to find a solution to attach the additional hardware to the rack, since it doesn’t have any special pins or whatever to hold them. Then again, these models were created to see how well these racks would print. The different hole size was a surprise for me which I need to include in my calculations.

And the three rack-less models? They’re just nice desk ornaments.I have ordered more prints so I will likely have more ornaments soon.

My next designs will have better racks, preferably with extra points to hold my hardware in place. The sandstone prints still look great but I have to consider the size of the whole thing. And I will need to experiment with clothing, to see which items will print best. The same is true with hair, since I still have to find hair that prints well in 3D.

All in all, 3D printing is a very interesting challenge. Slightly expensive too, though.

Shapeways 3D printing

Well, as you know, I like making 3D images. But nowadays there’s also an option of making 3D prints. You can do this with your own 3D printer or you’ll use the services of a company like Shapeways.

Personally, I want to experiment with my own 3D printers but finding a good one isn’t easy. On KickStarter, I found Tiko, the unibody 3D printer which looks great! So I supported it since I want one! It is now funded so they are working on creating it and then shipping it so I have to be patient before I can 3D print myself. And I’m not patient!

So I have experimented with Shapeways, which is fun. And my first experiments failed mostly. I noticed several interesting challenges because 3D printing and 3D rendering are two completely different things. Take, for example, this model that I’ve called Bianca:
Bianca Delmonde with Sword_0001

A nice bikini model wielding a sword and something I really would have liked in color. Unfortunately, Shapeways does offer color printing but the details on this model are too fine for this. They have colored sandstone and colored plastic. Unfortunately, sandstone is brittle during printing and the model might fall apart during handling. Full-color plastic is better but requires a minimum thickness of some parts and there’s a size limitation. The largest size allowed for this model resulted in too many thin walls. So I decided to go for strong, white plastic instead:


The drawback of white plastic is that I now have to paint it myself. Which is okay, since the print was perfect. Even her sword came out nicely. Only the bikini bottom had a flaw, since at one point of her backside, there’s a hollow area because the material was too thin. But hey, it looks funny so I don’t mind. 🙂

Still, I wanted a colored 3D print so I experimented a bit and decided to use this dinosaur as a model:


And I kept it just simple so I can experience what the material would look like. But also, it allowed me to see how well the sandstone can handle pointy, short things. And the result looks great:


Okay, not my finest picture but the result looks good. The sandstone glitters a bit, though. But the horns are great and the print was perfect, except for a broken toe. That’s basically a flaw that can happen with the chosen material.

There are many other materials to choose from, including metallic plastic and even expensive metals. But printing in those materials is complex and requires shapes with thicker walls and fewer details. Printing in gold is also very expensive because, gold! You don’t want to have big, gold models unless you have a big wad of money available.

For 3D printing, various techniques are used. The technique generally depends on the material used. Shapeways has a nice material selector for picking the materials you like and provides detailed information to use when you create your model. Metals are especially complex because they need to print a mold first. Once it is done, they have to pour the hot metal into the mold and then polish the result. Although fine details are possible, they might get lost during polishing and they might not reach all areas for polishing.

I have one model printed in Elasto plastic, which is fun stuff. This model can bounce since it’s a bit rubber-like. I have 4 models in hard plastic and two dinosaurs in sandstone, I’ve ordered a few more but they tend to be canceled because of small flaws that are discovered during manual checkups before they start printing. Often, it’s just the wall thickness, loose shells or other minor flaws but they are important because your finely detailed model might miss some fingers or other parts because these walls were too thin. Or the model is made from two or more parts and not all printers can print multiple parts.

Still, you can always tell Shapeways to print it anyways. I did so with several models and the results were fine. Except for one sandstone model, where the legs had broken off and some parts had shifted.

So, how do 3D printing and 3D rendering differ from one another? Well, there are a lot of differences and as I’ve discovered, when rendering I have some semi-transparent parts in my model that adds some special effects. For example, my model has a cornea that adds reflection or other special effects to the eye. But in a 3D print, there is no transparency so it becomes a blob over the colors of the iris.

Also, with rendering you tend to use bump mapping and set up special lighting to make the model look good. In printing, all you have is the shape of the model, nothing else. Details have to be part of the shape when printing while rendering images allows other tricks for those details.

And printing has only one color, unless you choose the 3D color printing options. You can still paint your model afterwards and to do so, I would recommend the strong, white plastic and acrylic paints. Of course, a color print is optional but the result might not be what you expect. Again, in a 3D rendering, the colors can be enhanced by using all kinds of techniques. For a 3D print, you’ll have to find a place in your house where the light will show your model from its best side.

Finally, the printing quality. If we were talking about 2D printer, we’d be talking at the number of DPI of a printer. In 3D world, we have to look at the volume of the smallest particle that the printer supports. And this also makes clear why 3D printing tends to be slow. If the smallest part is 0.2×0.2×0.2 millimeters and you’re printing something that fits a box of 20x20x30 centimeters then you’re using a lot of drops! Of course, the model will be smaller than such a box but my Bianca model was almost 80 cubic centimeters.

And to be honest, my 3D print needs a bit of polishing since those particles leave very, very tiny bumps on my model. Still, my sandstone dinosaur are made from bigger particles and feel like very fine sandpaper. Polishing should be possible, though. I just don’t want to risk it.

I’m still waiting for a few more models to return from the printer. I want my dinosaur in colored plastic just to see what that material is like. I also ordered it in white plastic for painting purposes. And I ordered two sandstone prints of this model:

Ruby on the Rocks model_0001

Two versions because I used two different hair styles.

I hope this will print well and to help the printing process, I made sure the model is on a plateau for stability and put the hands and feet against something solid. I’ve set the bikini top and bottom to the thickest setting and now I just have to wait until they can take it into production.

So, my conclusion is that 3D printing has its challenges. I still have to wait for my 3D printer to arrive before I can really start making my stuff but for now, Shapeways is providing me a great service for testing purposes. Okay, a lot of my models have been rejected for flaws but you can only learn from your flaws! So I’m fine with that. I just start all over again until it goes right.
