Most 3D editing tools use native file formats like .3DS, .ase, .lwo, .dae and others. 3D printers can only accept Gcode, which is usually be generated by slicers. Slicers, on the other hand, can allow STL , obj, 3mf, x3d. Through this process a single file may go through several different file types before it is 3D printed. With each conversion your mesh may be built up differently. Ultimately most of our users will either want to output directly in STL or Gcode to print. Our advice is to go as directly as possible from the original file to the end file for printing to make sure that multiple file conversions don’t mess with your design intent.
