Filament characteristics

[morgandc]

I am looking for a filament that is as good as PLA at "bridging" or short overhangs with a higher temp tolerance. After spending a week with PETG it doesn't look like it will do what I want. (internal large square thread). The PLA does a great job for me. according to the MatterHacker website they have a PET that is supposed to be good at bridging.

Recommendation? ABS, PET, nylon, high temp PLA?

Thanks,

See if you can't anneal the PLA in an oven for an hour at 110C or so. Tom Sanladerer found that it was impressively strong and about as good at heat tolerance as ABS, although it did shrink some.

Hmmm, just dawned on me that MH was probably using PET generically, including PETG. The PETG I have is very stringy, probably does bridge very well, just not overhang very well.

Oven cooking PLA might be an option, hoping there is a better option. I read somewhere that ABS did overhangs better than PLA, but was looking for real world info before I start ordering move filament types for testing.

Looking at the tech specs for several filaments I went ahead and ordered ABS today, it appeared to be the closest to PLA in key areas....we shall see.
