"additional accessories"

Filament
1

The website literature indicates that additional accessories are needed to print with poly-carbonate or nylon. What are these accessories?

Also, Garolite sheet from McMaster 8525K112 is only $7.30. I see no reason to purchase the more expensive machinable version.

Why use PEEK in the nozzle? Is there a suitable alternative that will allow higher melt temps for nylon 645? Does it really need to be made from a polymer? why not carbon or non ferrous metal?

For Polycarbonate, you need the Polyschnozzle kit. We don’t have this available for the Buda 2, but we will. For Nylon, you just need to change the print surface. We found the sanded Garolite has worked best, but still not perfect.
