PEKK - POLYETHERKETONEKETONE
A leading material in the PAEK family, PEKK has exceptional mechanical, thermal, and chemical resistance properties, while being substantially easier to print than PEEK.

PEI - POLYETHERIMIDE (ULTEM™ )
Polyetherimide is an amorphous, amber-to-transparent thermoplastic with characteristics similar to the related plastic PEEK. Relative to PEEK, PEI is cheaper, but is lower in impact strength and usable temperature

PSU - POLYSULFONE

Polyetherimide is an amorphous, amber-to-transparent thermoplastic with characteristics similar to the related plastic PEEK. Relative to PEEK, PEI is cheaper, but is lower in impact strength and usable temperature

PPSF/PPSU - POLYPHENYLSULFONE

Polyetherimide is an amorphous, amber-to-transparent thermoplastic with characteristics similar to the related plastic PEEK. Relative to PEEK, PEI is cheaper, but is lower in impact strength and usable temperature

PPS - POLYPHENYLENE SULFIDE

PPS 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.

PP - POLYPROPYLENE

Polypropylene has incredible chemical resistance, low density and very light weight, and has great temperature resistance and overall toughness. 

PC - POLYCARBONATE 

Polycarbonates used in engineering are strong, tough materials, and some grades are optically transparent. They are easily worked, molded, and thermoformed. Tough, rigid, and temperature resistant. 

PCTG - Copolyester 

Stronger, Tougher, and Clearer - Essentium PCTG is an easy-to-use material with incredible surface finish, superior toughness, and chemical resistance – use it just like PETG. With isotropic Z-Strength, it's one of our favorite materials!

PA - NYLON

Nylons are very tough, high tensile strength, with excellent ductility. It is widely used for gears, fittings, and bearings, in automotive industry for under-the-hood parts, and as a material for power tools housings. Gun frames, like the Glock, use a Nylon composite.
