PEEK offers excellent heat resistance, chemical resistance and mechanical strength, yet stable FFF printing is difficult, and getting from a printed shape to a part that can actually be used has been the real barrier. Working with Otsuka Chemical, Gutenberg has taken an approach that optimizes hardware and material together, combining the Japanese-made PEEK-capable printer G-ZERO MP1 with POTICON filament. This session reviews the techniques this required, from how to think about process conditions to suppressing warpage in thin plate geometries, and introduces the applications now opening up, including jigs and holders, sensor housings and electronic component trays. We also introduce a development grade with antistatic (ESD) performance and, as one example, the areas we aim to serve next, such as semiconductor cleaning, drying and reflow processes where static control is required.
