Hi all,
I’m looking for a high strength filament that’s easier to work with than polycarb. Has anyone out there used both of the above and can you comment on how they compare in terms of strength, rigidity and usability?
Cheers, Rob.

Hi,
I have recently bought a roll of 2.85 mm white HT filament.
Made some testprints for a customer who needed parts that could be subjected to higher temps.
Results so far is that HT does NOT stand up to an extended temperature of 100 degrees Celsius (in an oven that is).
As for strength, it of course depends on what your definition is for ‘strong’.
As far as I know, PC-filament has the highest tensile strength of any FDM filament, directly followed by PLA.
Just about every other filament has a lower TS and that includes PETG, XT, NGEN or HT (with ABS coming in last).
In my experience HT is about as strong as PETG and XT. It’s main feature is it’s temperature resistance.
When it comes to impact strength, all the PET(G)-variants are about equal, so you can use PETG just as good as HT or XT when temperaturs are below 80 degrees C.
