ASA is the go-to answer. You could also try filled ABS or ASA, either glass fiber or carbon fiber. The fibers do not make it any stronger per se, but they do mitigate shrink and warp to a large degree. If you do so, use a hardened steel or gemstone nozzle.
PETG may also be suitable for some applications.
Yep exactly. ASA for strength and/or outdoor use, PETG for everything else.
Pretty much this. ASA will still warp a little but it has half the shrinkage of ABS, is UV stable, and it gives off a lot less voltatiles while printing.
I did some reading before asking and ASA was mentioned as also having difficulties with warping. Has this not been the case in your experience?
Not the person you asked, but in my experience good (!) ASA is way better manageable. It still shrinks and can be annoying, but way less than ABS. As with ABS especially a good print bed and heated chamber is doing wonders.
On a glass plate + 3DLac + Brim it goes absolutely nowhere. Quite the opposite, I have to further cool down the plate and use a scraper to get it off. There might be better plates available, I just went with the oldschool structured glass because I wanted things to fucking work during print.
Thanks for the second opinion. Sounds like ASA is on the menu for a couple tryout prints.
That's because everyone starts with PLA, and PLA has the lowest shrink and warp of all commonly available materials... which is why it's so common and everyone starts with PLA.
Basically anything is going to warp more and compare poorly against PLA, but ASA's shrinkage after cooling is less than half of ABS, so it compares favorably to ABS in particular. 1.6% vs 0.7% or something similar. PLA's shrink rate, meanwhile, can be as low as 0.3% for competently manufactured blends. Shrinking while cooling is what causes warp, especially on broad flat objects.
Yeah, PLA is easy, it just doesn’t have the temp resistance and durability of better filaments. It’ll warp on a hot car seat in the summer.
