There is no strict limit on the number of polygons or triangles in your 3D file when using our platform for 3D printing. However, there is a restriction on the maximum file size of 500 MB per upload. It's important to understand that these two aspects are closely connected.

File resolution and size

Having an extremely high-resolution file can lead to an oversized file that may pose challenges for us to handle. Additionally, an overly detailed file may surpass the capabilities of most 3D printers and will thus not necessarily lead to a more detailed printing result.

Choosing the right file format and tolerance

For 3D printing, the most commonly used file format is STL, which stands for "Standard Triangle Language." This format represents your design as triangles in a 3D space. It's worth noting that STL is typically not the native format of your 3D modeling software, where your design is initially described as a mathematical function. 

In most 3D modeling software, you will have the option to export your file (for instance to STL) and will then be asked to define the tolerance for the export. This tolerance defines the maximum allowable distance between the original shape and the resulting STL mesh. We recommend choosing a tolerance of 0.01 mm for optimal results. Going lower than this value is unnecessary because most 3D printers can't reproduce details at such a fine level, and it will only make your file larger without improving print quality.
