Peek threads stripped. Any US supplies of a PEEK ?

Recommended Posts

My Peek threads stripped out and the hot end fell out of the peek during a print. Does anyone know a place where I can get a replacement peek ? Preferably in the United states.

I'm not going to ask how you managed that...

Mcmaster sells PEEK rods, 5/8in diameter, and you can machine it to spec yourself (1/4in drill for the well, M6 drill&tap for the brass tube) to make some form of rim on the top.

while you are at it, you could consider scrapping the 1/4in well on top, and replace it with a section with an M7 tap, and also thread the bowden with a M7... this will eliminate any bowden decoupling events.

If you end up making your own, I agree with Joergen, thread the bowden. I threaded mine M6 to fit the existing PEEK part and I never have problems with the hot end clogging or the bowden popping out.

Take a look at scottmayson's insulator here-



I think that would be a nice upgrade (in PEEK) if you have the tooling.

I ended up ordering the 5/8" Peek Rod from mcmaster, with a M6 tap and the appropriate drill bit. I like the idea to die the bowden and tap the top of the Peek.

I'll have to pick up the appropriate tooling for ACE hardware or home depot.

Also I picked up a $120 mini wood lathe from harbor freight.

I already had a mini drill press.

lets hope for no more hot end issues !!!!

    • "Back To The Future" using Generative Design & Investment Casting
      Designing for light-weight parts is becoming more important, and I’m a firm believer in the need to produce lighter weight, less over-engineered parts for the future. This is for sustainability reasons because we need to be using less raw materials and, in things like transportation, it impacts the energy usage of the product during it’s service life.
