HPRINT 144: Large-Volume 3D Printer and Multi-Extrusion Testbed
HPRINT is a material deposition-style custom 3D printer that I began working on way back in the summer of 2011. Before any fabrication began it went through a large number of design changes. When the first CAD models and assemblies were made it started off as a greatly enlarged and reinforced version of the Ultimaker. Later it transitioned through a prusa-like stage in an effort to cut down on complexity and cost, going back eventually to having a Cartesian gantry. In the course of assembly, an error was found with its belt path setup that made one of the two axes entirely nonfunctional, but a workaround was found: the h-bot configuration frequently used for pick-and-place machines. It is currently going through the final stages of updating for a fully-functional h-gantry system.
