Rhodia, the engineering plastics business unit at Solvay, has introduced a range of polyamide 6 powders called Sinterline for selective laser sintering (SLS).

Ralph Rissé, the business development manager at the unit, said: “Laser-sintered parts manufactured using Sinterline display a thermal resistance and stiffness similar to those injection moulded in polyamide 6. This innovation extends the limits of rapid manufacturing enabling cost-effective production of functional prototypes and small series components.”

Rhodia said Solution F/E2R, a company specializing in engineering and rapid prototyping techniques for recreational vehicles and aerospace applications, has manufactured parts such as air-intake ducts and brake fluid tanks which highlight the inherent qualities of the material. Other parts are being developed to equip the cockpit of the Solar Impulse, a solar-powered plane.
