<![CDATA[SoliForum - 3D Printing Community — weird artifacts]]> https://www.soliforum.com/topic/7770/weird-artifacts/ Wed, 24 Sep 2014 08:13:06 +0000 PunBB <![CDATA[Re: weird artifacts]]> https://www.soliforum.com/post/66923/#p66923 each printer depending on how manufacturing assembly was done can have slight variables that may need tweaking in slicer etc. Neutral ABS is closest to base default settings I find.
the "burnt" hole in your pic may have been either a spec of dirt or extruder too hot and made it pop as extruding looks like.
today I had issues getting a thin flat object to print solid without leaving lots of hollow surface crevices no matter how I re-configured slic3r on 4 prints of same file. and I just calibrated printer for fine tiny prints of several other STL files even with bridges. so its mostly trial and error working through some issues Im sorry to say. once you get a profile that works and save it with name so you remember type prints its for you will enjoy printing a lot more. my printer seems to do better quality at slower speeds than most run at. but fast and fair is not acceptable to me so I dont mind waiting 2-4 times longer for nice quality. also fast running is harder on printer components.
main thing to look at on rough side wall surface is have enough perimeters to cover infill well, and maybe slow speed of those areas being printed so it dont rip melted plastic loose moving past too fast. and let it smooth extrusion better. finer details need slower time. and dont over heat material. as stated above each printer can differ but mine ABS extruder set at 195c bed at 80c works as close to perfect as I can get. try doubling Perimeter layers and use at min 5 solid layers top and bottom. no speeds over 60 outside perimeters 40 and small and gap fil 30, bridges 10. most my prints are N scale vehicles etc so micro details. I have some infill etc thats thinner than Blonde hair strands. lol

Can you share theSlic3r settings for natural color abs please?

Here are some more pics showing ugly artifacts of my newer print (same STL):

Two circles in the front have those holes on their sides, also the area connecting one of the circle to the other is less thick then the rest of the walls, among other things.

Here you can see a (burnt?) hole on the top of the bigger circle.

Same as the first image. The areas between the circles are thin

The bottom part, its like few layers are missing or it was cut with a knife

maybe you can put your printer info in your signiture like most of us have also for better replies to issues your having.

Can someone explain what these strange artifacts are and how to prevent them?:

solidoodle ABS, 0.3mm layer height, Repetier Host, sliced with Slic3r.

This artifact was even more noticeable when I printed a Z axis adjuster replacement. http://www.thingiverse.com/thing:281477
The two holes where the screws had to go had similar holes on their sides, they were even see-through at places.
