Materials science / Re: right choice of plastic for 3D printed items
« on: February 04, 2019, 07:59:07 AM »
I recognize the company that you are using from the material options menu picture!  They do good work.  I have ordered a few of those different materials for prototypes for work.  With 3d printing especially, you need to be concerned with not only the material but the different process that they are printed with.

With out a doubt, I think your best bet is the multi-jet fusion PA12.  It is one of the more durable 3d printed materials I have played with while also still being very flexible.  When HP first released the multijet fusion printer, I was at atrade show and a vendor had printed a large zig zag type spring that would flex an impressive amount.  It is also significantly cheaper than some of the other options.  We have not done much hot testing with the PA12 so I can't completely speak to that but I think it will be similar to most plastics unless you are going to get into a high end engineered resin. 

please let me know if you have any other questions about this, I would be happy to help.  I have a small sample MJF pa12 part that is .100 inches thick.  i will toss it in an oven at 50* C and see how it changes its flexibility.

Edit: I just pulled the piece out of the heat chamber after sitting there for around 4 hours.  It seems a little bit more flexible but not hugely different.

Is this the three layer you are looking for?
I ordered a sample of this maybe a year ago with no issues.  I was considering making a poncho type deal for myself.

Full disclosure, I'm just a hobbiest/roll my own guy so no clue on the advertising a final product made with this type deal.

Kifaru sells a couple of different styles of stays.
