Delta 3D Printer Large Format

thingiverse

Update 6/3/2017 I'm currently modifying the design of this project, with plans to post pictures and files within the next week. My goal is to convert the printer into a ball screw driven system. Initially, I chose to use 8mm rods for the rails, but this resulted in excessive slop in the carriages. To eliminate this issue, I'm designing new carriages. Additionally, I plan to replace the existing 360 watt power supply with a 1000 watt HP server power supply. I aimed to create a Delta 3D printer with a large build plate capable of printing complex models. Specifications: Build plate: 18" diameter x 12" height E3D Volcano Hotend (future upgrade to dual extrusion) 20" Carbon arms with Traxxas ball ends 8mm Chrome rods for the rails 1.5" 8020 Aluminum T-Slot Extrusion Frame The build plate was initially a 1/4" waterjet aluminum plate with a heated PCB beneath, but it warped. I'm now using a makeshift 3/8" milled aluminum billet as the build plate. Solid fill printed PC-ABS corner brackets were designed and printed.

The Traxxas ball joints don't behave like they do in real life, which is a challenge to replicate accurately. If only magnetic ball and socket joints could handle loads as well as Traxxas ball joints can!
