A rigid black SLA material for durable, moisture-resistant parts with a smooth finish, offering up to 50% faster processing speeds.

Somos® WaterShed® Black is a specified stereolithography material engineered to produce strong, detailed parts with a true black finish directly off the machine. It combines defined mechanical properties with excellent surface quality, making it a reliable choice for both advanced prototyping and low-volume production runs.
Based on the proven technology of the WaterShed family, this material is a general-purpose resin that delivers specified performance data. Its key differentiator is a formulation that enables up to 50% faster processing speeds compared to other black SLA resins. This efficiency, combined with its inherent deep black color, eliminates the need for secondary painting, saving time and labor costs in the production workflow.
WaterShed® Black is designed for functional components that must withstand demanding conditions. It delivers parts that are stiff, tough, and dimensionally stable, featuring low water absorption (0.35%). This inherent moisture and chemical resistance ensures that components maintain their structural integrity and performance when exposed to harsh operating environments, making it ideal for automotive under-hood applications and consumer electronics housings.
Engineered for ease of use, WaterShed® Black streamlines the 3D printing process. Its fast print speed and minimal finishing requirements allow for quicker part delivery. The material produces a smooth surface finish that accurately captures fine details, reducing the need for manual or automated post-processing steps and allowing designers to achieve their desired aesthetic with less effort.
The versatility of WaterShed® Black supports the entire product development lifecycle. Its combination of speed, durability, and aesthetic quality makes it suitable for creating functional prototypes that closely mimic the look and feel of final products. Furthermore, its defined properties make it a viable solution for manufacturing end-use parts, jigs, fixtures, and other custom components for low-volume production.
