Workhorse XL - Large Scale DIY 3D Printer

The Workhorse XL is a larger version of the Workhorse Printer that we also published on Thingiverse here https://www.thingiverse.com/thing:2764064

This larger 3d printer design uses:
XYZ- axis Lead Screw
Fixed Bed
Moving Gantry

The large scale DIY 3d printer is a open source modular machine platform that uses lead screw driven motion to allow for an extended range of applications:
Pellet Extruder
Clay Extruder
Any application that involves moving more weight and moving mass.

Build Volume:
650mm x 650mm 650mm

While most 3d printers use belt driven motion in the x and y axis to increase print speed but loses quality when more weight is applied to the gantry or carriage. The lead screw used on the Workhorse has a high helix pitch with multiple threads to allow increased print speeds while maintaining the quality provided from lead screw and ball screw motion.
