The best sites to sell STL files and 3D models.

The best websites and marketplaces to sell 3D models

Our favorite marketplace to sell 3D models is Pinshape, as it has a large and active user community and a very nice interface.

Cults.

  • Commission rate: 20% of the selling price without taxes

Pinshape

  • Commission rate: 30% of the selling price (including VAT)

Threeding

  • Commission rate: The standard commission fee rate is 8.5% of the sale price including VAT but minimum USD 0.45/ EUR 0.45. However, this commission may be lower for nonprofit organizations such as museums, educational organizations, foundations, private collector, etc. The commission may be higher if Threeding helps you to prepare your models in a 3D printing friendly format.

What are the most used files format for 3D printing?

STL

The STL format is the most used file format in 3D printing. STL stands for stereolithography and was originally created by 3D Systems. It is the main 3D file format used for FFF and FDM desktop 3D printers. This format approximates the surfaces of a solid model with triangles: the more triangles, the more accurate the 3D design.  

OBJ

OBJ is an open file format used by Wavefront’s Advanced Visualizer for polygonal objects or free forms ones. Many designs softwares can export to OBJ and this format is often used in 3D printing.

VRML

VRML stands for “Virtual Reality Modeling Language”. VRML is a 3D digital file format supporting color, therefore it can be used with 3D printers that have at least two extruders or full-color 3D printers.

AMF

AMF stands for Additive Manufacturing File Format and is a 3D model file format starting to become standard. AMF supports color and can be compressed to about half the size of a compressed STL file making it very interesting.

G-Code

G-Code is a numeric language used by people to instruct computerized machines including 3D printers. In the case of 3D printers, the G-code is the actual file which will be read by the 3D printer (via SD card or USB in general). The Gcode file contains the instructions for the 3D printer to build the object layer by layer (starting point, the direction and the speed of the nozzle etc). G-codes files are generated from STL files or other 3D files formats using a slicer software, which will convert a 3D drawing into horizontal layers with instructions on how to build them for the 3D printer.

How to open an STL file?

To open an STL file there are two main options:

  • Use an STL viewer: you can find many free ones online. You don’t even need to download a software, so it won’t take any space on your computer.
  • Use a 3D design software: you have to download a software and from it you can open your STL file and edit it.

How to download an STL file?

Downloading STL files is a very easy process. Here are the steps:

  • Go on a 3D model repository/marketplace of your choice (see our list above)
  • Find a 3D design you like using the filters or the search bar (if there are a lot of “likes” on a 3D design it usually means it’s good)
  • Click on the 3D model and read all the characteristics to make sure that’s the one
  • Click on download

In this article we decided to focus on the STL files repositories, marketplaces and search engines the most adapted to 3D printing (we are a 3D printing specialized company after all). We presented our selection of the best websites to download free STL files for 3D printing.
