I have 3D printers at my school, but unfortunately they are not super high quality. I want to try 3D printing a model I made on google sketchup, but I would like for it to be fairly accurate.
What measures can I take to prevent error in the model? I understand that I need to export the file as an STL; is there anything I can do to the model before hand to ensure accuracy?
What can I do to calibrate a 3D printer for best results?
