Description
Multi-head Simultaneous Independent 3D Printer - Revision 1
Copyright 2025 Bowler LLC.
For more information, software, a full bill of materials, and build instructions, see https://bowler.llc/projects/.
USPTO Patent Pending.
This multi-head 3D printer utilizes multiple simultaneous and independent heads to allow the operator to print multiple copies of a part, print in multiple colors (at once and separately), print in multiple materials (at once and separately), and, in future versions, break up large prints into regions that are printed simultaneously. The design features a 1230mm x 410mm x 450mm print bed and utilizes Duet/RepRap to open up the possibilities for what can be printed.
Use the files below to quote printing. PLA is fine for all "P" parts. The "PS" parts have very thin walls, these parts may require other services/consultation. Increase infill for structural components. (Note, P28 should be replaced with just an M4 nut since embedding it is not allowed)
