- Can use different print heads by adjusting the height of the Z-axis
- Interchangeable print surfaces for different applications
- Multiple print head attachment points
- Powered fume removal system
- Print head-mounted cooling fans
- Linear bearings for smooth (and large) operation
This design is different from other kit printers we’ve seen, and it looks promising. We’re going to watch developments to see how this experiment proceeds. If successful, it might influence the design of future 3D printers.

But can you get one of these for yourself? Not yet, as Jim is still in the design and experimentation stage. But he’s promised to show us what happens. He says:
I created Grass Roots Engineering so I could share the developments and continual improvements of my 3D printing machines.
One question we have, beyond the engineering of the device, is its name. A device such as this deserves a very cool name. Any suggestions?
