Introducing the Workhorse and Workhorse XL 3D Printer


WorkHorse 3D Printer

The Workhorse Printer is a open source large 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. 

Lead Screw Driven Motion

While most 3d printers use belt driven motion in the x and y axis to increase print speed but a belt driven motion system may lose quality when more weight is applied to the gantry or carriage. The Workhorse utilizes Igus lead screw on the X and Y-Axis. The high helix pitch includes a twelve start thread to allow increased print speeds while maintaining the quality of a ball printer. The robust and rigid motion 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. We originally designed the fdm 3d printers to be driven by ball screws but quickly switched to multi-start lead screw to increase travel speed. If your looking for a belt driven configuration check out our new corexy kit.

Build Area

  • Print size millimeters (xyz): 650 x 350 x 350 mm
  • Print size inches (xyz): 25.6 x 13.7 x 13.7 inches

Imagine having the print volume to 3d print the large objects that you’ve always dreamed of printing with room to add on additional print heads and an optional pellet extruder.

Fixed Bed

While most large format printers use a moving bed that moves along the Z-Axis, the Workhorse’s fixed bed and moving gantry design is more ideal for the large scale 3d printing process.

Custom Mods & Upgrades

The Workhorse 3d printer is available with custom mods and upgrades. We’ve several custom designed machines for many of our customers. If there is a specific size or requirement you just give us a shout.  Additive manufacturing has many applications and we designed this modular platform to be adaptable and scalable for your industrial printing needs.
