Choosing the right material for your project is important. We offer many different urethanes and silicones in a wide range of durometers. Data sheets of materials in stock are available for download.
We prefer you send a .stp or .x_t file if you are not familiar with exporting a good .stl file. It is very important to know the correct way to export a .stl file because the way you export the .stl will determine the quality of the part that is produced. To learn how to export a good .stl file please refer to the section labeled Creating a .STL file.
