Fixed Bed / Moving Gantry

The Workhorse Printer is a large format 3d printer some friends and I have been working on for the past three years. The large 3d printer is a modular machine platform that uses lead screw driven motion with a fixed bed / moving gantry.

• Fixed Bed / Moving Gantry

• X and Y-Axis Lead Screw

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. We designed the machine for applications that require more weight to the gantry or carriage such as materials such as clay, chocolate, plastic pellet extrusion. The increase weight that is moved

around which without decreased quality or reduced print speeds.
