ABS is nice, PETG good, ASA hard to print, PLA holds up(but don’t recommend).
Dem overhangs, tho. Did you print this upside down, with the open end on the print bed? It looks quite good.
I think PETG is probably a good choice for this application. PLA, especially if it's thin walled as I suspect it is here, will disintegrate pretty quickly with continued exposure to temperature variations, moisture, and sunlight.
ABS is infamously pretty vulnerable to UV, also. You could protect it (or any of the others, really) with a coat of paint.
Printed right side up. Everything was achieved via support setting optimization, and heated support removal where necessary (nose and lip in particular).
PLA holds up alright, but it’s gets brittle. There are just better choices.
Interesting point about the ABS, it appears to be holding up very good, but I’ll monitor it overtime.
You're saying ABS is printing easier for you than ASA? That's interesting. From my limited understanding, ASA has the reputation of being easier to print.
What brands/blends? I've been printing basically only ASA and PETG for a little while now. Haven't tried ABS.
Yes in my experience, ABS is an easier print.
For ASA, I think maybe Sainsmart. They also do bad tpu, so maybe source was the problem.
How do you handle fumes with ASA? they are much worse than ABS, imo.
Huh, any particular ABS brand(s)? I am tempted to grab a roll. I've been running polymaker's ASA and other than warpage on big parts with my lower chamber temps (yay big printer with lots of enclosure surface area) it prints fairly well.
I run the filter inside an enclosed printer with an exhaust fan.
Microcenter ABS is pretty nice. In general they do some good stuff.
Of course you run exhaust fans! I run Bambi’s with enclosures, I don’t have an exhaust fan setup yet.
I often wonder about fumes and cancer risks.
Thanks! I'll have to stop by and pick up a spool. I would rather start with something that prints well for someon else than some random spool.
I'm guessing you mean Bambu? If so, you could print a [Nevermore](https://github.com/nevermore3d] and/or Bento box. They're both in-chamber active carbon filters and will help cut down on fumes. This is all I was running before the exhaust fan. Regarding the exhaust fan, I've found I don't need much flow - just enough to keep a slight negative pressure in the printer. I remember finding someone who ran their exhaust fan through a 3m respirator cartridge and they found that to be pretty effective when combined with an in-chamber carbon filter.
Oh! Thanks for this. It seems like something worth looking into
