Printing high performance plastics on your 3D printer requires some special hardware such as a thermocouple and all metal hotend, but the most important thing is a heated chamber. Up to now all the DIY solutions have been made for aesthetics with transparent sides. To actually make a functional chamber for printing high temperature and high performance plastics you need to insulate, seal, and actively heat the chamber. Single wall acrylic sides won't do the job.
