Print in progress: Character anatomy tool print, question.

Hey guys i've been using my Prusa i3 Mk3s, and have recently switched from the original base PLA, to Prusament's PETG.

I got 3 main issues/ questions:

I'm currently getting some burn pieces or darker pieces from my 3d print, I figure it might be caused by a stall in the print causing the PETG to burn.

I'm also getting quite a bit of stringiness to the print, and what are some good recommendations on stringiness cleanup.

Last one is tough, the 3d model I've made is proving difficult to print in one piece, there is some overhanging pieces making it impossible to make a clean print. I was wondering if there were any good resources or any pointers on how to cut complex 3d models.

3d Model

Burn Piece behind the leg REALLY rough temination/Really tough getting a good edge fingers are also rough:

 

Version 2:

All of these prints were using Prusa Slicer on 0.05mm ultradetail mk3 using prusament PETG with support: everywhere.

 

Can't seem to get better cuts for a better print =(

RE: Print in progress: Character anatomy tool print, question.

Typical first step on stringiness is reduce the print temp a bit. Maybe 5 degrees at a time?

Do testing on test towers; it will be quicker than your detailed model. Ultradetail will be more stringy in any case.

It might work for you cleaning the model up with a heat gun. The strings will vanish.

RE: Print in progress: Character anatomy tool print, question.

I've printed many figures, and use both Meshmixer tree supports and slicer support structures. Both have pluses and minuses.  I try to not cut parts since that requires effort to add pins and the final assembly always leaves artifacts.  I'll cut for size (too large for the bed), but not generally for printability.

Tuning supports in Prusa Slicer is pretty easy, but trial and error is the method I end up using.  Adjust, slice, review; repeat.  After a while and a few prints you'll discover what works and what doesn't.  Also, now that modifiers are available and very easy to use, making supports only where they are needed is almost trivial.

Supports in Meshmixer are also easy, but not intuitive. Watch a few of the videos available on using supports, they are editable only at certain times, and if you move out of the support tool they are fixed.  For me, Undo is not reliable for supports, so save often, and keep multiple versions so you can restore to an earlier point. lol.  

ps: ditto on the heatgun.  Saves tons of grief trying to control stringing.  That said, folks say PETG soaks up moisture and starts stringing. So drying your filament may be a good idea.
