Many design software can export to OBJ and this format is also common in 3D printing. OBJ is an open file format that Wavefront’s Advanced Visualizer uses for polygonal or free-form objects. This format approximates the surfaces of a solid model with triangles: the more triangles, the more accurate the 3D design. It is the main 3D file format used for FFF and FDM desktop 3D printers. The STL format is the most common file format in 3D printing. STL stands for stereolithography and is originally a 3D Systems creation. What are the most common file formats for 3D printing? STL This website is specialized in medical STL models. Embodi3DĮmbodi3D receives 15% of the sale price, plus $0.30 per sale (transaction fee). The commission may be higher if Threeding helps prepare the models in a 3D-printing-friendly format. However, this commission may be lower for non-profit organizations such as museums, schools, foundations, private collectors, etc. The standard commission fee rate is 8.5% of the sale price (minimum $0.45) including VAT. Pinshape adds 30% of the designer’s price, so the commission is paid by the buyer and not the designer. Their commission is 20% of the selling price (excluding VAT), which includes bank fees (about 5% of the commission). Here are a few of our favorite 3D print file marketplaces.
