3D Printing For Tough And Flexible Models

Print with Simulated Polypropylene to rapidly produce durable prototypes that look and behave like polypropylene.


Using two Polyjet printing materials, manufacturers can print prototypes that simulate the appearance and functionality of polypropylene to test form, fit, and function for applications such as snap-fit assemblies, hinges, durable housings, and packaging. Rigur (RGD450) acts as an advanced polypropylene material substitute that offers durability and great surface finishes. Use Rigur in any office-friendly environment to gain reliable performance and stable prototypes. Durus (RGD430) is the original Simulated Polypropylene material that exhibits great impact resilience and an elongation at break of 44%.
