3DPlatform recently made this very large #3DBenchy.
Recently we 3D printed a large (15lb 11oz) benchy. The large boat benchy was printed on the HFE300 out of PLA with a 2mm nozzle, 1mm layer height, at 32mm/s, 10% infill, 3 bottom layers, 3 top layers, and 2 perimeters. The extruder was set to 240C. The overall size is 600.01mm x 310.04mm x 480.0mm and it took 19 hours to complete the print.
