Arcus3D M2 - Six material, active mixing linear delta 3d printer.

Got around to wrapping this up.
Letter boxes were printed at 180mm/sec.
Background for each letter was done with a large nozzle by printing just the brim.

MRRF2017 was exhausting, and awesome. Free beer!

I showed up with spare parts for everything that could possibly go wrong this time, and of course, then everything worked perfectly.

I killed a feed tube between the hot/cold transition 2 days before the show while cleaning it up when I cut into it with a razor, so only 5 of 6 channels were active for the show.

Got featured on hackaday.

He got a lot of stuff wrong, like the name of the company, the name of the printer. Nothing important...
But I guess that's mostly my fault for not having my signage ready and just putting up what I had from the Madison Makerfaire.

Very nice. Really good progress in a number of areas.
