The Big Boy 3D Printer
An Incredibly Overbuilt 3D Printer that has elements of generative design, a custom tool changer, and lots of rigidity.
Learn additive and subtractive Manufacturing methodology and The Design Process by building an experimental 3d printer/mill hybrid from scratch.
Print Area of 330mm x 475mm x 500mm
We tried to design with the biggest print area we could reasonably manufacture.
Overall Size: 700mm x 700mm x 900mm
Our requirement was for the printer to fit through a standard door. We were able to meet that requirement.
Weight: Approximately 250 lbs
Since this is steel construction through and through, the printer weighs a fair bit. This weight and rigidity make it easy to add a spindle.
Reliable 80mm/s Print Speed
The 7 NEMA 23 steppers provide more than enough speed and force to move the X,Y, and Z axes.
Custom Designed Tool Changer
Our custom milled dovetail magnetic tool changer is a completely novel design, we even had to buy a special insert for manufacturing it!
