DSM Somos® NeXt LV Grey
Categories: Polymer; 3D Printing/Additive Manufacturing Polymer

Material Notes: The second member of the Somos® NeXt family, Somos® NeXt LV Grey delivers the durability and functionality, with a finer resolution of details and faster part processing.

This third-generation, high-impact Somos® material is designed for creating tough, high-quality, complex parts that are more resistant to fracture and cracking than standard SL resins—leading to a longer pattern life.

Somos® NeXt LV Grey produces durable, grey parts with high resolution detail. The ABS-like parts have a high modulus while maintaining a low viscosity for easier cleaning and reduced part processing times.

This solution is ideal for functional end-use performance prototypes including snap-fit designs, impellers, duct work, connectors and electronic covers, automotive housings and dashboard assemblies, packaging and sporting goods. We serve the aerospace, automotive, consumer products and electronics industry segments with this solution.
