50 MICRON PRINTING

This is a quick blog documenting something I tested today almost purely to test the ability of the Printrbot Metal at hitting low layer heights. Previously I have never done anything below 100 micron.

I wanted a chess piece and I found this

What intrigued me about it was the internal structure, the twisted helix.

How well could it handle this? Only one way to find out!

Print started great except for that little blob of green I didn't see until a while in, too late to stop it.

Wow that's a lot of layers, Shrek would be proud.

Amazing... no visible layer lines anywhere. Probably a testament to the filament as well.

But how did it handle the real challenge, the twisted internal structure? Well... pretty damn good I might say!

Now what everyone wants to know…
Printrbot Metal (1403)
‘Australian Made’ Bronze PLA
Sliced with Simplify3D
Run off Repetier-host
Temp = 210*C
Printing speed capped at 42mm/s
Nozzle Diameter = 0.4mm
Layer height = 0.05mm
3 walls, 30% infil

For reference, I capped the printing speed low since I knew printing it fast wouldn’t work and I wanted maximum quality.
