DIY Large Scale 3D Printer With All Lead Screws

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.

Lead Screw vs Belt Driven Motion

Large Build Area

Large Scale 3D Printing
  • Print size millimeters (xyz): 650 x 350 x 350 mm
  • Print size inches (xyz): 25.6 x 13.7 x 13.7 inches

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.

Nema 23 Stepper Motors

In order to drive the lead screw we had to use Nema 23's instead of the typical Nema 17 stepper motors found on most 3d printers and machine custom motor mounts.

    • Reduced the weight and footprint of the Y-Axis Carriage.
    • Experimenting with Igus anti backlash lead screw nuts.
    • Trying out different direct drive extruder designs

    I'm considering making the X and Y-axis C-Carriage designs from solid rectangular bar instead 2" x 4" aluminum tubing. There will be a increase in wasted and machine time but the over all weight and footprint will decrease. The more compact design will allow faster printing speeds due to reduced deflection within the system.

Hey -- in the Project Details, the paragraph that starts "While most 3d printers [...]" is duplicated, and the first copy has a line break in the wrong place at one spot. Just FYI ;)

I hate typso like that... they suck!

(Yes I did that on purpose. I'm a wise*** like that!)
