feldman early research

Carve Wright

Pros:

- 3 axis: rolling pad and 2 dimensional motor head

- Package comes with specialized software (do everything in on go)

- Includes a USB drive unique to the machine for easy data transfer  

Cons:

- Can only carve wood

This machine got me thinking about creating a rolling pad for our CnC machine to allow extremely large projects to be done with ease.

MTM Snap

http://mtm.cba.mit.edu/machines/mtm_snap-lock/

Pros:

- Threaded rods for movements (no belts)

- Thick plastic chassis

- Drill wood, metal, and circuits

- Very cheap (~$650)

Cons:

- Very small work space = 6" x 4" x 1.75"

- No clear way of holding down material

This machine fits most of the things we wanted. This is a great base to go off of.

Example of more than 3 axis

FABtotum

Pros:

- Mill, 3D print, and scan

- Similar build to 3D machine (threaded rod for z axis and belts for XY)

- More than 3 axis (?)

Briefcase 3D printer

While this machine's ability to fit into a briefcase, the most interesting thing I found was the idea of replaceable heads. I believe we can incorporate this into our CnC milling machine to create a multipurpose tool for the average home user.
