The last 3D printer I built, for Artis GmbH. Has a 570/670/1100 mm print space, printing speeds up to 200mm/sec and movement up to 1500mm/sec.
The body took 1.5 hour to print, the 1 meter high rocket(!) 7 hours, and the vase 5 hours. all of them with a 0.3mm layer height.
This printer is built to last with high quality electronics and materials.
The complete machine conception took 8 days, and 40 days to get it print the 3 tests you can see in the pictures below. It is running under Megatronics 3, has a heated bed and is completely enclosed.
