The Workhorse XL is a larger version of the Workhorse Printer. Although the original design is modular and made to be expanded upon the frame extrusions must be beefed up to maintain regidity.
The Workhorse Printer is a large format, open source 3d printer released by 3D Distributed in 2018. The unique printer is a modular machine platform that uses lead screw driven motion to allow for an extended range of applications.
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.
The robust and rigid system is particularly useful in applications that add more weight to the gantry or carriage. Materials such as clay, chocolate, plastic pellet extrusion or other foods can increase weight that is moved around which results decreased quality or print speeds.
