These printed parts are temperature resistant alternative to ABS printed hotend parts.
A high enough printing temperature can create a high enough ambient temperature around the hotend heat block that can warp and deform the surrounding ABS parts. Specifically, the cooling ducts in the Voron Afterburner toolhead.
This is a consideration for the Dragon toolhead that will depend on how high of a temperature you will be printing at.
However with a Mosquito hotend and it’s wider heatblock, warping and deformation of the part cooling duct is almost certain.
This is where material with a higher temperature resistance becomes necessary.
These ducts are printed out of Polymaker PA6-CF, a carbon fibre filled Nylon with a temperature resistance of 196c and is extremely rigid.
