Design Ethos

The PolyNC project was started with the following considerations in mind. It is believed that, ultimately, 3D printers will need to be able to create human scale objects if their use is to become common place.

Large Format 3D Printing

The cube on the left is a visualization of the size of one meter cube. 3D Printers having at least one axis (i.e. x, y or z) being one meter or more, is considered to be a large format 3D printer. Their costs are usually more than most family vehicles. PolyNC’s aim is to provide the ability to do such printing at a much more attainable cost.

An Open, Accessable Frame


The frame design should allow the machine to turn any surface into a build surface. Machines that move the build area (be it 3D printer or CNC mill) limit their end use to things that can fit on the bed. With PolyNC the bottom of the machine is open allowing for possibilities that cannot be done any other way.

Palet Shuttle

A common CNC operation in which the “bed” area can be switched out easily. With the current frame design, implementing such features is trivial, as compared to the complexities that would befall most other printer designs.

PolyNC is a Robotics Platform – A Cartesian Robot

Above all else, PolyNC is meant to be a General Purpose Cartesian Robot. This means that it can be converted from CNC Milling to 3D printer by the end user.

Some of the uses for such a robot include:

  • CNC Milling
  • Pen Plotter
  • Vinyl Cutting, Stenciling cutting, Paper cutting, Cloth cutting, Cardboard cutting)
  • 3D Printing
  • Pick and Place
  • Embroidery
  • Laser Etching
