Polyamide specialist Solvay Engineering Plastics (Lyon, France) has introduced a new 40 percent glass-filled grade of its range of Sinterline polyamide 6 powders designed for selective laser sintering (SLS) in automotive under-the-hood components, electrical and consumer goods. Based on the same resin chemistry as Solvay’s established Technyl polyamides, Sinterline reportedly delivers prototyping parts with functional properties and bridges the gap between visual prototyping and injection molded PA6 or PA 6/6 components. Solvay says this material creates time and cost savings for OEMs and Tier 1 suppliers (e.g., in the automotive industry) as it can provide more predictable results in functional prototype testing, minimize the need for pre-production tooling and speed the way from design to market. Sinterline powder grade offers a tensile modulus of 6300 MPa at 23°C/73°F, combined with a porosity of 1.8 percent.
