Rigid Polysulfone Sheets

- Color: Amber
- Temperature Range: -40° to 285° F
- Tensile Strength: 11,800 psi (Good)
- Impact Strength: 1.3 ft.-lbs./in. (Poor)
- Hardness: Rockwell M120 (Extra Hard)
- For Use Outdoors: No
- Specifications Met: FDA Compliant 21 CFR 177.1655, UL 94 V-0
Widely used to make parts that require autoclaving such as trays and handles, these hard, rigid sheets are easy to machine and thermoform. Polysulfone resists expanding and maintains its strength when exposed to heat and steam.

High-Temperature 3D Printer Filaments


Parts made with these filaments remain strong and rigid in temperatures that would soften most plastics. They are a lightweight alternative to machined metal parts. Use with a fused filament fabrication (FFF) 3D printer to make parts that will be used near ovens, engines, and other hot machinery. These filaments require an all-metal extruder to reach the recommended printing temperatures. Print parts onto a heated bed to keep them from warping as they cool.
For parts that need to be sterilized, use PSU filaments. Parts printed with these filaments are rigid and hard. They won’t expand or deform when exposed to heat and steam, so you can autoclave them.
Tensile strength is the best measure of a filament's overall strength. Similar to the stress applied on a rope during a game of tug-of-war, it's the amount of pulling force a material can handle before breaking. A higher rating means a stronger filament. A tensile strength of 5,000 psi and above is considered good; 12,000 psi and above is excellent.
Maximum exposure temperature is the point at which a printed part will begin to deform. Above this temperature, your printed parts will start to lose structural integrity.
