Calibration Print

thingiverse

A straightforward calibration/stress test print. Print without supports - that's what this is all about! Overall dimensions: 20mm wide, 40mm long, and 30mm high. Two vertical holes are present, each with a diameter of 5mm and 3mm respectively. A half-circle shape along one side has a diameter of 10mm. The bridge pillars measure 5x5mm, the gap is 5mm, and the beams are also 5x5mm in size. The large arch features a diameter of 36mm. This print tests your overhangs with the arch and your bridging - aka cooling - capabilities through the bridges. Basic X/Y/Z calibration and extrusion are also put to the test. On my printer, at 60mm/s it takes less than 30 minutes to complete. At 30mm/s it takes around an hour. Neither of my printer/slicer combinations can produce a perfect print. Ideally, the slicer would generate perimeters from outside in unless detecting an overhang greater than 45 degrees, then do inside out. It's also best if perimeters never start on an overhang and infill starts from a solid area, not the edge of an overhang. This model was created using Tinkercad.
