PPS (Polyphenylene Sulfide) is a high-performance polymer that exhibits exceptional chemical resistance along with high thermal and mechanical properties. Widely known as one of the most chemically resistant thermoplastic materials available, PPS is insoluble in any known solvent under 200°C. PPS is used in some of the most demanding applications in Auto, Chemical Processing, Oil & Gas, and Electronics. It is inherently flame retardant and self extinguishing, making it an ideal material for electrical / electronics applications.
Polycarbonate is used EVERYWHERE -- there’s probably some within reach of you, as you’re watching this video: Electronic components, as a good insulator while being heat-resistant and flame-retardant; construction materials, like dome lights, glazing, roofing sheets, sound walls; In data storage, all those CD’s, DVD’s, and Blu-Rays are made of polycarbonate… in sheets/films, it’s used for signs, displays, and posters. Widely used in the automotive and aircraft industries, it’s used for headlamp lenses, fasteners, bullet-proof glass, product packaging, even the cockpit canopy in the F-22 Raptor is made from polycarbonate. Ever sat in a massage chair? There’s a good chance the bulges massaging you are made from polycarbonate, especially if it has a heat function. It’s also used for many kinds of Bypass ducts, fluid routing tubes, high-strength brackets, and tool replacements

Print Temperature:315-345c
Bed Temperature 120-160c - for adhesive, our Nano Polymer Adhesive works great, this stuff sticks down on the bed very well.
Chamber Temperature: 60-90c
Support material: Supports: ThermaX High-Temp Support is specially built to work with high-temp materials like this, and Aquasys 180 is also another great option if you want solubility.

Annealing: Parts printed with PPS must be annealed after printing to ramp-up the crystallization in the resin. This will maximize mechanical, thermal, and chemical resistance properties. Full annealing generally requires 2-4 hours of heating at 130°C.

Drying: yes, you MUST dry this filament. Like almost every thermoplastic, this does need to be dried thoroughly before processing, which is the fancy word for melting.

In regards to drying, we’ve got an entire kit available on our site, including the vacuum chamber and ovens -- that’s basically all you need, so we put together the stuff WE use at OUR shop, so that you can do it just as easily as us. We also made METAL spools, so you don’t have to worry about melting or warping your spool when drying at high temps.
