DETROIT—DuPont Transportation & Advanced Polymers recently unveiled new additions to its 3D printing portfolio.
The firm debuted new Zytel polyamide and Hytrel thermoplastic polyester elastomer pellets and Hytrel filaments. DuPont said the new pelletized materials were developed to help increase 3D manufacturing agility and improve cost-effectiveness by allowing customers to smoothly switch from prototyping to small-series, pre-series and mass production.
DuPont's glass fiber-reinforced, carbon fiber-reinforced and unreinforced grades of Zytel polyamide each have different specialties. The glass fiber-reinforced grade feature a heat deflection temperature greater than 150°C, good surface finish and resistance to common solvents and chemicals, the firm said.
The carbon fiber-reinforced grades are lighter and stronger, which DuPont said makes them more suitable for highly demanding industries such as aerospace and automotive.
The unreinforced grades are ideal for functional 3D printed parts that require good aesthetics, elongation and low friction properties.
The firm's Hytrel TPC-ET compound was developed for use in flexible and functional parts. DuPont said the pellets and filaments deliver strong 3D printing performance and are available in multiple hardnesses.
