Hello, I am currently designing a 3d printer and I plan on using leadscrews throughout, 2 for z axis, 2 for x axis and one for y axis, Has anyone got a printer with similar set up? What challanges did you face with this? Is there anything special that I need to consider that I might overlook?
Yes, don’t use lead screws for a 3D printer, just for the slow moving axis (like the Z axis), lead screws are not able handle to fast motion and direction change required by 3D printing process, unless u sacrifices speed and acceleration. Also their accuracy is not better compered to good quality belts.
You can use ball screws for better performance with a much higher prize, but this will dramatically increase the moving mass in the XY axis = stonger frame and motors with the same result provided in the end as belts.
As 3D printing is additive manufacture process there are no forces applied to the XY axis during print process just the gravity, and fight with inertia so no need to have a mechanics with high force output, unless you want to use it also as a CNC mill.
