Description:

The SHORTCAT is a 18″ tall, 12″ wide Pyramid framed 3D printer.

X-travel: 155mm
Y-Travel: 170-190mm
Z-travel: 210-220mm


This machine is made by: mrkimrobotics.com

Design:

The SHORTCAT applies TALLCAT style design in a more compact form factor.

By bending the supports into a pyramid shape, a symmetrical base is possible that uses no frame spacers. This significantly extends the x-axis travel and allows a 8″ wide table to exit the front and back of the machine on the y-axis. A thin-profile 360 bearing allows for clearance from the shorter pyramid.

Y-Carriage v3.0:

Version 3.0 has been reduced to a single part.
The v3 y-carriage integrates an adjustable table and bearing assembly in a single layer.
