DuPont Transportation & Advanced Polymers is the global business unit of Dow DuPont's Specialty Products division, which officially officially launched at 2011 at the International Precision Molding and 3D Printing Manufacturing Exhibition (Formnext 2018) in Frankfurt, Germany. Introduced a new 3D printed composite filament.
3D printing using DuPont's Zytel specialty nylon's "Ultra Low Shrinkage Technology", this new product meets the industry's need for harder, stronger materials. According to DuPont, the performance of this material is comparable to existing reinforced grades, but it does not affect its printability, smoothness and surface quality .
The two new products will be available in January 2019, including fiberglass reinforced polyamide and carbon fiber reinforced polyamide. According to DuPont, both grades allow users to achieve greater design freedom, lighter weight, and shorter product development cycles for rapid prototyping, making part production, tooling, and product customization easier.

Formulation, mechanical (performance) and chemical properties. New glass and carbon-enhanced 3D fiber materials are a new step in this direction, helping the industry move towards cost-effective, automated and mass production. â€
Two new grades are:
â—Zytel 3D12G30FL BK309 is a black, heat-stable 30% glass fiber reinforced polyamide with a modulus of 4-5GPa and a heat distortion temperature of >150°C. It is resistant to most solvents, detergents, and at room temperature. Automotive liquids and fuels.
â—Zytel 3D10C20FL BK544 is a black, 20% carbon fiber reinforced polyamide suitable for lightweight parts with a modulus of 4-5GPa and a heat distortion temperature of >150°C. It is resistant to most solvents and detergents at room temperature. , automotive liquids and fuels.
Both products are on display at Formnext 2018 in Frankfurt, Germany. To demonstrate the quality of the materials, DuPont's partner, RepRap's X400 and X500 3D printers, were printed on-site.
