How to import files, and which file format is best for 3D printing
Polyprod opens many kinds of files, such as STL, OBJ and 3MF. Each format has its pros and cons:
STL: the most popular, well compressed and compatible with almost every 3D software. OBJ: very useful if you work with textures or materials. 3MF: made for 3D printing, it stores many separate parts in a single file.
