Large Format 3D Printing Tech Tips

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.

When 3D printing larger prints we have found there are some problem areas caused by printing with a large model at such fast speeds to watch out for. First, 3D printing with such a large nozzle has its challenges, as we have found out on the pellet feed printer and the HFE900 printing we have done on the Excel.

Also, corners tend to be difficult because the bead is much more round and not as sharp when heading into the corners.

To avoid these printing issues here are a couple tips that we have used to circumvent problem areas. Adding additional top layers, and increasing the outline overlap are a couple of options to help with this issue we have found. Additionally, speeding up on the bridge will help as well. Lastly, moving faster stretches the filament to provide a better base for the next layer to print onto.

We hope these tips will help you avoid 3D printing blunders on your next project. We’d love to hear other ideas that have worked for you!
