In 2019 I decided that it was time to try and fulfill my futuristic custom vehicle manufacturing vision and buy a large format 3D printer. After reviewing a bunch of options I settled on the Erectorbot 864. It can print in a variety of media including carbon nylon and TPU flexible filament and was the least expensive option in its class and size. The print envelope of this unit is 8’x6’x4’ which is big enough to print most any automotive body panel or frame member. I hoped it would make structural and functional parts in carbon but have had difficulty getting it to work as well as I would like. The main issue is the small nozzle size of .7-1.5mm does not align well with parts that are really big. It simply takes too long to make the parts, and the longer the print time the more likely something will fail. I have been working to improve the speed and customize larger nozzle sizes with some success, but its a work in progress!
