Has anyone tried #Quadrap-3d-printer with steel square tubing? Is it at all tempting to use steel tubing for any reason? Less expansion with temperature?, more weight for a more stable frame? I am thinking at something just like Prusa Steel but for a different printer form factor.
Qr1500 - 40x40 steel tube, still under construction
cool, any Link to some blog/forum?
btw 40x40 is beefy, what size are you after?
1400x1400x768 print area
Any progress or some pic? Would be nice to see that.
