Filament strength question

Postby ExLondoner » Thu Jan 26, 2017 6:55 pm

We're trying to find the correct filament to print out tubes (approx 10" x 3").

The filament must be super strong - is there such a kind?

strong it what way, high pressure? shear or compression?

Nylon -X is looking to be very interesting, alternatively look into polycarbonate also google search, there have been several tests but the winner depends on how you define strong.

What about shear strength, i.e. layer adhesion? Anything particularly stand out there?

I'm not sure a 3D printed part will produce what you want if you need something to hold pressure. Unless you are planning to use it to make a part that will be used to make a mold for plaster or sand casting. layer adhesion is not likely to hold the pressure at all.

when I was working on the waterbloc, it ended up leaking from somewhere internally. which why I am going to seek an alternate method of cooling.

also don't forget that most printed parts get much stronger after annealing, but most folks don't bother

Yes I was thinking strength in the form of compression.

I've been using NylonX and it's working out quite well. There's another filament named CarbonX which I plan to try out as well.

Thanks for the responses!

Yeah but if you're doing something that requires press fitting bearings, aligning shafts, etc... it's not such a simple task.

Try Polymaker PC-Max, I constantly use it and it is strong as hell. Also, increase the number of shells to improve resistance (#shells impact more the strenght of a printed than increasing the infill)
