No calibration other than settings in slicer. This is the 3rd print from this machine. The obvious bands are where Iwas playing with speed and where i ran out of filament and had to do a change whilst running!.

I am sure you'll agree that black ABS shows the worst of a printer, but this just looks so much better in real life. I am so impressed and know that running slower would have produced an even better result. My next test will be 50 microns

This is Black Dynamite Bust Black Dynamite Bust

Very nice. You must be a skilled builder. Well done!

Was this from a Mendel90 in an enclosed box? I have had problems with ABS down to delamination of the layers which I feel is down to the ambient temperature being too low to enable a proper bond. Saying that, I have never gone down to 0.1mm layer height - what nozzle diameter are you using?
Must say - cracking quality!

Build quality is nophead's design with dibond sheets, they are so tight in every direction, anything else to me is now a compromise..

Nozzle size was 0.4, Unenclosed in a cold room, that black ABS stinks, so windows open, Perimeters was 3 (more is better with large ABS, about 1.2mm walls in this case) and filament was 3mm..

Very nice print.
At what temperature are you extruding the ABS? I generally use 230C but have recently been playing with 240C if a piece delaminates during printing. You don't seem to have that problem.

Looks excellent!
What slicer do you use? And what bed?
–°an you post macro pic of surface?
The only issue I see is "ringing" but this is common problem...

Printed at 240C, the fan was running at 50% as this ABS doesn't freeze very quickly.

used slic3r 0.98 and standard prusa bed as shipped by nophead in his kit.

Tell me about this "ringing" what am i looking for? The first pic tried to explain the change of quality due to me playing about

not macro shots as I can't be arsed to get out the macro rings, but 100% from images posted



very nice print.
How long the print took and what size it have ?
please show us your 50micron print to!

i cant wait to get my mendel90, hopefully next week hot smiley

This was about 4 hours 25 min (i played with speed during print), height is 10cm, width 2.8cm & depth 3.3cm. Printed from SD card. An impressive printer, take your time, smooth the extruder gears of all tiny bumps (ever so gently) and read all that is writtenwinking smiley

For "corner ringing" see here
You can see it on last pic clearly.
BTW with that high quality you may scale down the model to print "micro" version

Thanks Karabas,

I didn't see the rings as i was looking at the z-layers (thinking rings there). I contacted nophead and he suggested reducing acceleration to 2000 on the x and y, so will try that on a tiny version.

cheers

What head speed did you use?
Did you try kisslicer?
