Metal filled PETG?
I would like to find metal filled PETG instead of PLA. I have a design that has a small amount of constant pressure from a Beryllium copper strip inside. With PETG and a 1mm wall this does not cause deformity over time but with metal filled PLA it does. With a 1mm (@ 0.2 layers) layer it will start showing deformity in weeks and with a 3mm layer over a period of months. Anyone seen any and if not anyone know why it isn't made?

have you heat treated the metal filed pla after printing? that should significantly increase the resistance of the material?
like the htpla from proto pasta
I was using Colorfabb bronze, brass, and copper. I do have some Protopasta steel, iron, and conductive but they are PLA. Guess I'll grab some Protopasta copper htpla and give that a whirl. I still don't understand why no one makes metal filled PETG. Perhaps the mix doesn't work well.

I bet you could ask Proto pasta directly and probably get a response.
Well, the annealed metal filled HTPLA lasted longer but is deforming also. I did email Proto pasta and the reply was they were not aware of any technical issues with making metal filled PETG and asked what properties I needed that the metal filled HTPLA didn't have. I haven't heard from them since I replied. I did think about making a void in the print and inserting a thin metal plate below the point that is deforming so I might try that.

You may be able to try Priline Carbon-PC. Even though it's listed as polycarbonate it's obviously a blend since I have been able to print it quite successfully on my Taz6 printer without an enclosure at 260C and I believe I was only using 85C bed. The carbon fibers in it help stiffen it up.
I don't know if links are allowed but I'll try.

Here is what I would try, Carbon Fiber PC from Snolabs. Excellent quality filament!
I use Atomic CF PETG when I need CF, what I'm looking for is metal infused (brass, copper, bronze, stainless) for looks.
