30M

History

This is our enclosed benchtop model.

• The System was introduced during our KickStarter campaign, and came with a 23" tall enclosure.
• The System 30 was an improvement made while fulfilling our KickStarter obligations, and came with a larger (30" tall) enclosure.
• The System 30M was introduced in 2013, and came with a change to all metric fasteners and custom extrusions, and a single (vs double) front door.
• The System 30M v2 was introduced in 2021, and comes with better motors with closed-loop feedback and quieter operation.

Technical Data

Temperature

• The HotBed can be heated to any temperature up to 90°C.
• The enclosure may be heated to 55°C if desired.

Resolution

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)

Accuracy

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

Repeatability

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 normally use a 200µm (.2mm) layer height with the .5mm nozzle for filaments.
• We normally use a 500 µm (.5mm) layer height with the #14 (1.6mm) Luer Needle for emulsifiables, liquids, and gels.

Print Speed

Remember that the print speed you set is not necessarily the print speed you routinely achieve - the move has to be long enough to allow the head to accelerate to that speed and also decelerate by the end of the move. 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.

With Repetrel v3.0 and above, we normally print at up to 50 mm/sec or 3000 mm/min; earlier versions should not exceed 30mm/sec or 1800mm/min, as this is what the accel/decel rates are tuned for.

With the System 30M v2, the closed-loop motors allow good quality prints at up to 5000 mm/min

Please note that clays and gels usually perform better at slower speeds.

Build Volume

Systems have a build volume of just over 200 x 200 x 200 mm.

Form Factor

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

Adjustments

• 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?
