The TITAN is a 190x190x190mm machine designed for portability. It's the printer you take with you when you want to print something at a friends place. It has a build envelope of 80x80x70mm.

It's currently under development, and the first prototype is being build. It's a huge challenge to get all parts as small as possible.

Current problems:

  • The Z stage cannot have a motor under it. Currently attempting an winching system.
  • The HotEnd is an Ultimaker hotend (due to having a spare). But this hotend is quite large for the machine.
  • Electronics are not yet fit into the design. I might design new electronics based on an LPCxpresso and 4 Pololu drivers.


People have many suggestions for this machine. Many of those can be tried later on.

  • Use a car-jack like system for the Z stage
  • Use wire instead of timing belts
  • Investigate if a CoreXY frame could save space
  • Investigate if you could remove 2 of the X/Y frame axes and just have the moving axes slide in a slot (requires a very rigid slider block)
  • Design a custom, smaller hotend
