For my customers needing special parts, of course at-home (repairs, mods, hobbies, sculptures, etc) and at-work (my regular job). For the latter I design and print parts for R&D test rigs which are one-off.

Continuously moving towards more technical plastics. ABS is the main workhorse. Poly-carbonate (PC-MAX is a dream to work with) is well under control now, and getting to grips with PEI filament (need special parts for 160 C working temperature and organic solvent resistance). For the latter I am modifying a printer to reach 360 C hot end temp, and a temp-controlled heated chamber (ceramic heater+fan) up to 60 C.
