I am a 3D designer, where can I sell my 3D models or STL files?

There are plenty of websites where you can sell your 3D printable file or 3D model.Whether for 3D design wizards or hobbyists with good 3D modeling skills, many 3D file marketplaces allow users to put their 3D models up for sale. 

The principle is simple: when a user downloads a 3D model, the designer receives earnings (minus the marketplace’s commission).

Some 3D designers choose to share their 3D models for free, but in return ask for financial support on collaborative platforms such as Patreon.

For example, the designer Agustin Flowalistik offers his 3D designs for free on Cults.ThingiverseYouMagine, and MyMiniFactory but accepts support on Patreon.

The best websites and marketplaces to sell 3D models

Here are a few of our favorite 3D print file marketplaces.

Cults.

Their commission is 20% of the selling price (excluding VAT), which includes bank fees (about 5% of the commission).

Pinshape

Pinshape adds 30% of the designer’s price, so the commission is paid by the buyer and not the designer.

Threeding

The standard commission fee rate is 8.5% of the sale price (minimum $0.45) including VAT. However, this commission may be lower for non-profit organizations such as museums, schools, foundations, private collectors, etc. The commission may be higher if Threeding helps prepare the models in a 3D-printing-friendly format.

Embodi3D

Embodi3D receives 15% of the sale price, plus $0.30 per sale (transaction fee). This website is specialized in medical STL models.

What are the most common file formats for 3D printing?

STL

The STL format is the most common file format in 3D printing. STL stands for stereolithography and is originally a 3D Systems creation. 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 that Wavefront’s Advanced Visualizer uses for polygonal or free-form objects. Many design software can export to OBJ and this format is also common in 3D printing.

VRML

VRML stands for “Virtual Reality Modeling Language”. VRML is a 3D digital file format that supports color. Therefore, full-color 3D printers or dual extruder 3D printers may use this format.

AMF

AMF stands for Additive Manufacturing File Format and is becoming more and more standard in 3D printing. AMF supports color. Most of all, it is possible to compress AMF files to about half the size of an STL file.

G-Code

G-Code is a numerical language used to instruct CNC (computer numerical control) machines, including 3D printers. In the case of 3D printers, the G-Code is the actual file that the 3D printer reads.

The G-Code 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.). It is possible to generate G-Code files from STL files or other formats using slicer software.

Slicing software converts 3D drawings into horizontal layers with instructions for the 3D printer.

How to download an STL file?

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

  • Go to a 3D model repository/marketplace (see our list above)
  • Find a 3D design 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

How to open an STL file?

To open an STL file, there are two main options:

  • STL viewer: there are many free ones online, without having to download any software.
  • 3D design software: after downloading the software, it is possible to open an STL file and edit it.

In this article, we focus on STL file repositories, marketplaces, and search engines that are the most compatible with 3D printing.
