TwoUp stress test on tiny and fine details

Posted on July 27, 2014July 27, 2014 by Ianmcmill

While printing @ 0.3mm most of the more for speed reasons I wanted to print some really fine detailed things. I’ve found that Elizabeth is just right for that purpose. Graceful and petite. Even more if scaled to mice-dimensions. So I brought her down the net and wiped away my curiosity. I scaled the thingiverse model down to 0.5 in slic3r and set the layer height to 0.1mm.
Printing time was about 3 hours and took circa 3.5m of filament. See end of post for slic3r settings.

Elizabeeeeeth !!!

Not quite perfect. No wait…Far from perfect ! But judge for yourself. Picture-galore after the break.

As you can see cooling (again) is very important. Even more though on very small details. The fan duct is 1″/2.5cm away from the nozzle and directs the airflow by a 1cm by 1cm opening to the printing surface. Another fan without a duct, that conducts cooling to the whole part is advisable I guess.

Slic3r settings are as following:
