Filament to make rigid objects

Hello, as of today, what is the best filament to use to make rigid objects such as brackets/frames on the Up Plus 2? Thanks.

I reckon ABS is the most rigid material with some bending strength. PLA maybe be a bit more rigid, however it is also brittle and biodegrades. Taulman nylon is strongest in terms of bending, but is a lot less rigid than both ABS & PLA.

Just my twopenceworth.

cheers

Thanks. After reading the postings here, I thought nylon were the strongest. However, after I watched the videos of some products made of nylon, I realised that it is the stronglest in terms of not breaking easily when pulled from the sides. I am looking for strongest in terms of rigidity.

Probably PLA is hardest. If you need it stiffer, you could always add gussets.

Taulman 645 is more rigid than 618, and warps less, it's my favorite. T-Glase is also said to be very strong ("like printing with steel" someone said) but I haven't done too much with it. I have some Taulman "Bridge" on the way and will report after testing.

PLA is rigid but brittle, as others have stated. Support removal is a bitch.

Thanks. Please do let us know how it goes with Taulman 645.

I tried PLA on a Makerbot a year ago. I didn't like it. The stock ABS which comes with the Up Plus 2 seems to be better.

Taulman 645 is great, I use it a lot; it's Taulman "Bridge" that's new and which I will be testing soon. "The strength of 645 at the cost of ABS, with less moisture uptake and less warping" I think is the advertised feature set in a nutshell.

Hi Julie, have you had a chance to test the 645?

Hello, any update in regard to the test results of 645 ?

It's worth checking out Polymakr polymax now too. An ABS strong and PLA stiff material - the best of both worlds.

More like "nylon-strong" - PolyMax is tough stuff (but not all that rigid, it's got some flex to it)
