Bending of complex prints
Hello, gang.
There is a potentially large order of parts from which one of the features is the possibility of bending of the structure (photo from SpaceClaim below). What kind of plastic it is possible to provide the maximum service time bendable element? I tried some PLA and Colorfabb XT Clear of, but an integrity violation occurs after approximately 50 of flexion.

Re: Bending of complex prints
I don't think we have any FFF filaments that would be suitable for this, what is the angle of bend?
And the thickness at the bend point?
Just looking at my samples , what about,
Taulman 3D, Nylon 618
Taulman 3D, PC TPE
Polymaker, PolyFlex
Kai Parthy, Bendlay
Others I think will fail quickly.

Thickness is about 5-6 layers in Cura. Angle equal 30 degrees, i think. Height/width of big element on a picture is 5/3 cm.
Yep, nylon must be a best option for this.

Re: Bending of complex prints
Taulman Bridge is probably the easiest nylon to print, provided you keep it really dry, although that's not necessary during printing. It takes a while to dial in the temperatures, so you will need to experiment with that. Your other option is PETG, if you send me the file I can try it in my printer and bend it 50 times and show you the resulting pic. I don't see any dimensions, but if it can be printed with a 0.8mm nozzle and 0.3mm layer height you should get a very strong print indeed. PETG can take a fair bit of bending, not like nylon though, but I have printed springs with it and they worked pretty well.

Re: Bending of complex prints
When I printed the support angles for our big frame structure I was impressed by nylon (Taulman Bridge) as it would flex instead of breaking.
Now 30° might be a lot...
Flex PLA is another option, but it is not really a 'technical filament'...

Maybe this?

Re: Bending of complex prints
I would look at Taulman Alloy 910

Re: Bending of complex prints
Done. I tested it by bending it 270 degrees around 150 times. OK, my kids helped. Well, they really did most of the work. Come on, I bent it at least 20 times myself!ivan.akapulko wrote: Attached. Many thanks in advance!
You can't really tell that it has been bent at all.
PM your address so I can send the print to you.

270 is more than I could have hoped!! Thank you very much again. Sent address in PMdanilius wrote:Done. I tested it by bending it 270 degrees around 150 times. OK, my kids helped.

Re: Bending of complex prints
Nylon is incredible in that respect. Weirdest filament I have worked with. I really like it though, because where it works it outshines everything else.
