Request for Hoffman

Uncle_Rollo

Could you please pin a list of preferred materials for all your various designs? Something along the lines of below with some notes on why the materials are good, better and best. The list could be updated as you test new materials as well. I really like the testing you do and the way the results are presented. Just looking for a quick and easy way to find the materials I need and can print. Thanks for all your work!

Uncle_Rollo It's all pretty much the same except for the Super Safety.

hoffmantactical So your current favorites are PET-CF followed by PA612-CF for heat resistant parts from lowers to super safeties?

The pdf that comes with the orca download has a list with various materials and why they are used for specific parts.

PistollPeet It does, but that list is pretty outdated.

Uncle_Rollo Pretty much. The PA612-CF is a bit tougher once annealed, but the PET-CF is easier to use due to not requiring annealing.

+1 for PA612-CF. It's kind of the unicorn material for these things if you print and anneal by polymaker best practices. On top of how well it does the heat and pressure I've even managed to get it to a mirror finish with coarse sand, wet sand 1000, dremel pad, buffing wheel.
