Our models and surfaces

From this web-site you may download and utilize these three resources:

• solids: These solid files are in the STL file format, a common format used to distribute 3D files that are intended to be printed on your own 3D filament or SLA printer. Often these files require no more work than to print any other STL file you might download and print. Each solid file contains the solid itself, marked with the URL of this site as a model code that clearly identifies the human model. Our goal is to make every 3D printed model easy to look up, so that anyone wishing to find out more about a model can use the code on the physical model to find the information about the human model here on our site.

• surfaces: Surface files are also in the STL file format, but are not printable. These files are provided for people to use in any way they see fit. You can import these files into 3D modeling software with the goal of creating a new model/surface. What you end up doing with these files, is entirely up to you! We encourage creators who use one of our surfaces to still include the model code so that users may still look up the information about the model on our site.

• screenshots: Each of our 3D models has a screenshot image that we use to display previews on our site. These images are useful for sharing links and communicating about this project online.

All of these files are released under the Creative Commons CC0 (public domain) dedication. This means we reserve no rights and you may do anything you wish with these files. We kindly ask that you do nice things with these files and ideally link back to this site as the original source of the solid/surface/screenshot.

How to print our models

We work hard to create models that are ready for printing. However, the process is still a bit of an artistic undertaking and prone to massive amounts of errors at every step. A lot of our solid files are not perfect, but they are good enough. If you feel that the errors that remain in our files are unacceptable, we'd love to receive improved models from our users. You can find our model repository at GitHub and if you have an improved solid/surface, please open a pull request there.

Printing our models should be pretty straightforward -- the solid files are ready to print. The units of the solid files are in millimeters (mm) and we work hard to ensure that the scale of the models is correct. If you print one of our solids at 100% (e.g. without scaling it before printing) it should print life-size just like the original human model. We recommend using non-transparent filament to print models that are intended for educational purposes -- transparent filament makes it harder to see details on a print.

Most of our models should be ready to import into your favorite slicing/printing software. Some may need rotations and quite a few will likely need to be scaled down, unless you have a very large printer. When printing breast models you may want to consider standing the model up (as they are shown on our site) in order to avoid unsightly countour lines. Some experimentation might be needed to get a clean print, but overall it should not be very hard.

Tips for specific models

• Penis models: These often times print better if the models are oriented so that the tip of the penis points up.
• Body models: Lower body, upper body and full body scans often print best with the model code down.
• Breast models: Breast models can print well in their orientation as downloaded, but sometimes contour lines can be visible if the layer height is not fine enough. Standing the model up, as the person would stand normally, can give better results.
• Vulva models: These are the easiest to print, simply print them in the same orientation as downloaded. However, the standing models (with an S in the second letter of the model code, such as VSNN) will need a rotation to print correctly.
