    Obviously one of the big marketing points for the r1 is its ability to print a wide range of materials. However, instead of asking what I CAN use, I instead ask you what materials I should avoid for one reason or another. I bring this up because I've been wanting to expand into some really exotic stuff like magnetic iron and ceramic (among many others). I assume that my r1, which still is using its original parts, would be able to handle most of these but I figured I should probably know where to draw the line. Thanks!

    You are fine on just about anything. Just know that most of the special exotics are a bit abrasive so you will need to replace nozzle eventually. In that case a hardened steel (not stainless) nozzle is a good investment

    And since it is a open design (not encased) a filament like ABS, while not impossible to print, can be more problematic than most.

    Can you recommend a place that sells kits of hardened steel nozzles of various sizes? From what I understand, materials like wood often require a larger nozzle size than what I have

    They suggest a 0.5 or larger for wood filament

    Also, you will not be able to reliably print flex filament with stock hotend

    Because you need something to guide the filament down to the heat break - or the hobb bolt will just chew up the filament. It's just not rigid enough. The way around it is to install a PTFE (Bowden) tube in it. Im sure this mod has been done to the stock hotend, but I am not familiar with that. Most of us just go E3D V6.
