Toorcamp: Type A Machines

Type A Machines designs and builds 3D printers in San Francisco. [Miloh], one of the founders, brought two of their flagship Series 1 printers to Toorcamp. He printed out a variety of models including water tight cups and quadcopter arms.

The RepRap Arduino MEGA Pololu Shield (RAMPS) is used to drive the stepper motors for each axis, as well as the extruder. This is attached to an Arduino MEGA running the Marlin RepRap firmware. Type A Machines ships the printer with Polylactic Acid (PLA) filament, which is biodegradable.

On software side, you start with a 3D model in STL format. This can be exported from 3D software such as Google SketchUp or Autodesk 123D. You then need a slicer to generate G-code and machine control software to command the printer. [Miloh] used Slic3r and Repetier for his workflow, but he also pointed out a good summary of 3D printer workflows.

The Series 1 was launched at the Bay Area Maker Faire this past May. It has a print volume of 1200 mL, which is the largest print volume of any desktop printer around. The Series 1 brings another option into the low-cost 3D printer market.

    I love hyperbole:
    “volume that eclipses the competition with a full 729 cubic inches (9″ x 9″ x 9″).”

    Ultimaker:
    “~ 210 x 210 x 220 mm, almost 10 liters (single tool mode) / 8.27″ x 8.27″ x 8.67″ ”

    Bigger, absolutely, but not eclipsing, that’s a bit strong :) But, I love competition in this market and I hope they do well and grow.

      thefutureis3d.com sells a Prusa derivative that has a 16″x16″x21″ build volume. Others have done similar, often based on MendelMax. Rostock can be built to practically any height, so there’s that too.

      That said this is a nice design. I’d be interested to see how fast it can go with the X motor on the Y carriage and the extruder on the X.

    That 3D printer workflow is old and outdated.

    1200 mL is probably not what you meant, you should be saying 11946 mL (or 12000 mL), if it’s 9x9x9 inches.

    You say 1200 mL, when it should be 11946 mL, or ~12L, if it is a 9x9x9 inch print volume.
