System Models

The System 23 was only offered during the KickStarter campaign. All backers were given the opportunity to upgrade to the System 30. This subsequently evolved into the System 30M, which is the only enclosed model offered as of January, 2016. Differences are detailed below:

Technical Data


  • The HotBed can be heated to any temperature up to 70°C by default, and up to 110°C if reconfigured.
  • The MK-1 can be heated to 260°C (limited life); we recommend sustained use at 250°C or below. PLA, PET, ABS and Nylon work well at 225-230°C
  • The EMO-25 prints at room temperature
  • The VOL-25 can be heated to 100°C

For more details about each head, see the page for that head.


Our positional resolution is better than five microns in the X and Y (.0002”, or 2/10 of a mil or .2 mils), and better than half a micron in the Z (.0002”, or 2/100 of a mil or .02 mils)


Our positional accuracy is +/- 50 microns in the X and Y over an 8” travel area And +/- 20 microns in the Z over an 8” travel area


Our positional repeatability is about 25 microns in the X and Y (.001”, or 1 mil) And about 10 microns in the Z (.0004”, or 4/10 of a mil or 0.4 mils)

Layer Height

We have successfully printed in ABS with a 25µm (.025mm) layer height, but this is very time consuming.

  • We often use a 300µm (.3mm) layer height with the .5mm nozzle on the MK-1 for 1.75mm filaments.
  • We often use a 600 µm (.6mm) layer height with the 1mm nozzle on the EMO-25 for pasty extrudables.

Print Speed

The best print speed manageable (without sacrificing quality) is variable, and depends not only on the material being used and layer height, but also on how much mass is being moved in the X and Y. We normally print at 1.5m/min, or 25mm/sec with both the MK-1 and the EMO-25

Build Volume

Systems have a build volume of 225 x 225 x 200 mm.

Form Factor

See chart above; dimensions include the top-loading (System-23) or side-loading (System-30) filament areas.


  • Speed of travel (at slicing or in g-code editor)
  • Layer thickness (at slicing)
  • Volume of flow per unit distance (at slicing or in g-code editor)
  • Extruder temperature (at slicing, in g-code editor, or manually during build) (MK-1, VOL-25)
  • Cooling Fan speed (at slicing, in g-code editor, or manually during build (MK-1, QS-1)
  • HotBed Temperature (at slicing, in g-code editor, or manually during build)

Or, is tabular better?
