Hollow HD test for resin printers, 5mm tall for quick print, High Def

thingiverse

This "Hello World" calibration model is designed for quick, hassle-free printing without supports. It includes a hollow cuboid with dimensions of 5mm in height and features 1mm thick (unless specified otherwise). The smallest feature is a cylinder with diameters of 0.75mm and reducing to 0.4mm at the tip. High-definition STL files are provided for precise printing, while low-definition versions are available on Thingiverse for visualization purposes. The model also features several rounded items like a cylinder with radius 4+1mm, two arches of 1mm thickness, a sphere quarter with diameter 10 and wall thickness 1mm, a hollowed half cube with fillets at varying sizes, six graduated cylinders from 1-3.5 diameters, a spring with 1mm thickness and 0.5 tall base, and a unique cylinder with reducing diameters. Version 4 introduced a 1mm tall star with three-quarters of a cone on top, as well as a "fusillo" pasta object. Slicing settings for .B9J are at 50xy and 50.8z, using Spot-A-HT version 7 resin that was reused multiple times. The printing process involved curing 4 base layers for 10 seconds each, followed by 3+2 seconds per layer upwards. Notably, the hollow cube printed perfectly with a 3mm resin exit hole, leaving no resin inside.
