We found a helpful discussion about using high-temperature 3D printing thermoplastics like PEEK and ULTEM as alternatives to metal.

A recent article in PlasticsToday showed how plastic gears molded of Vestakeep polyetheretherketone (PEEK) from Evonik are being used in automobile transmissions reportedly for the first time. To replace metal gears, Evonik developed a PEEK molding compound with the tribological properties and durability that can withstand the harsh environment of internal combustion engines. The component is manufactured by IMS Gear SE & Co KGaA and is used by Mercedes-Benz AG in various models.
