What's the strongest material I can print using the UM2/3

Recommended Posts

So I'm looking to print something that needs to meet a certain strength requirement, namely it has to have to be relatively stiff. I have already tried the typical PLA, ABS and PETG materials but they're all not stiff enough for the purposes I was hoping. Is there any suggestions what materials I should look at and where I can potentially get them?

Thanks in advance.

The absolute toughest, with the highest tg temp and strength I have found is polycarbonate.

There may be tougher out there though. But if you want to check out the printing needs for PC filament, check HERE and the product page HERE to see the pertinent data sheets.

I have not been printing for long, but this stuff is impressive and following the directions I linked to will make things better. The only thing I could add, if you do not have a door, is to tape some bubble wrap across the front and do it early in a preheat phase so the ambient temp in the build area can come to an equilibrium before printing.

Keep in mind that strength will depend on how many walls and percentage and type of infill. Will also depend on how thin the part is.

Thanks for the info, will check it out!

 

My pleasure :) And, keep asking questions as they arise. There are plenty of good people here that will actually answer you with respect and decidedly good information. I actually count on them to correct me, and they have, so that I have a better understanding.

If it is stiffness (not necessarily the same thing as strength) you have a demand for, you should look at a CF filled like the Colorfabb XT-CF20, it is insanely stiff (6.2GPa in Flexural Modulus) compared to Polycarbonate that "just" is about 2GPa.

Out of curiosity, and noobness, the CF means Carbon Fibre and is that not abrasive for the brass nozzles that come on the UM Models? Basically, killing the nozzles very quickly.

@kmanstudios: Yes, the CF means carbon fibre, and it is extremely abrasive, it kills a brass nozzle in just a few hundred grams.

This is the difference after 300 grams, the nozzle is just trash by this point.

The best solution is to get a ruby tipped nozzle like The Olsson Ruby, but if you only print quite limited amounts and want to spend less you can also go with a hardened steel nozzle.
