Filament for the printer is created on our own modified Lyman / Mulier version 5 Filament Extruder:
This printer was designed to print very large scale using recycled ABS plastic (we also recycle, shred and produce recycled ABS filament).
Most of the other very large scale printers out there tend to print in PLA which is a lot less problematic at large scale.
- Build volume 1200mm x 1200mm x 600mm
- H bot layout with fixed heat-bed (4 x z-axis motors to move the light weight H frame rather than the insanely heavy heat-bed)
- 1mm nozzle, double volcano extruder hot end to increase flow rate (80W total heater power)
- 2400W heatbed using 4 x 230V 600W 400mm x 400mm silicone heating pads (controlled with 25A solid state relay)
- 2 x Recycled Nema23 stepper motors for y-axis, driven by single 5A CNC type stepper driver
- 4 x Recycled Nema23 stepper motors for z-axis, driven by single 5A CNC type stepper driver
- 1 x Recycled Nema23 stepper motor for x-axis, driven by standard 2.5A stepper driver
- 1 x Recycled Nema17 stepper motor for extruder, driven by standard 2.5A stepper driver
- Designed in Sketchup Make 2017, design file included in downloads (Sub33D v3.07.09.skp)
- Frame built from 50mm x 50mm x 2mm box section aluminium
- Total build cost is close to $2000 AUD
- Marlin-RC firmware also included in downloads (Marlin-RC.zip)
If anyone is thinking to build something like this I would recommend using a 12mm heat-bed plate (rather than 6mm) as the aluminium plate deforms up to 5mm when heated to 90 deg C, I am using 9 x 9 point auto-bed leveling to pick up the deformation shape).
Also the 400mm x 400m 600W silicone heaters are a little small as the distance between them causes around a 10 deg C difference on the heat-bed surface between the heaters and above them).
I'm Currently fitting 4 x 150W IR heaters to reduce heat-bed deformation and maintain consistent heat on printed ABS parts.
Special thanks to Substation33 for all the support and recycled materials.
