Welcome to the Fab@Home Chassis Page
Here you can look at all of the variants of the Fab@Home Chassis. The chassis is the mechanical parts of robotic positioning system, not including the deposition tool or the electronics. What subassemblies the chassis comprises may depend on the particular variant of the chassis.
Fab@Home Model 2 Chassis
The Standard Fab@Home Model 2 Fabber has a 3-axis, Cartesian gantry configuration. It comprises several subassemblies:
- The machine base, which holds and encloses all of the other subassemblies.
- A bridge which moves along the x axis
- A carriage which moves along the y axis on which the tools mount with a quick release mechanism.
- A Z-table which positions the build surface vertically relative to the deposition tool

Fab@Home Model 1 Chassis
Model 1 Standard Chassis
The Fab@Home Model 1 Standard Chassis has a 3-axis, Cartesian gantry configuration. It comprises several subassemblies:
- A machine base, which holds and encloses all of the other subassemblies
- An XY-Carriage which moves the deposition tool along paths within the XY-plane to build a layer of the part
- A Z-Carriage which positions the build surface vertically relative to the deposition tool

Model 1 Chassis Variants
Model 1 - CNC Mill as a Chasis
A quick and very inexpensive way for 3D Printing is to add a Model 1 deposition tool to a CNC Milling Machine. The Milling Machine provides X / Y / Z Axis movement. There are a few alterations that have to be made to attach a Model 1 to a milling machine, but this should be a fairly easy retro for a person who runs a milling machine. The following site shows such an alteration made to a Sherline 2000 Mill: http://www.3dprintheads.org/ This Milling Machine now has additive and subtractive ability. It may not look like a model 1, but that is essentially what it is. The stepper motor is a bit more powerful and attached on the side, and the syringe is inside the black housing:
