Stereolithography (SLA)

Stereolithography (SLA) produces extremely complex prototypes with excellent accuracy and surface finish. The strength and detail resolution of SLA makes it the best 3D printing technology for form and fit test models, appearance models and master patterns for RTV molding.

InterPRO offers many SLA materials to choose from, including glass clear, high impact strength, high HTD and Class VI medical grade. The wide range of available materials makes SLA ideal for flow testing and visualization, functional testing, wind tunnel models, metal casting patterns, thermoforming molds, and fixtures for assembly.

InterPRO operates nine SLA high resolution and large frame SLA systems in-house.

Recommended Minimum Feature Size

SLA Nano: 0.008″
VIPER high resolution: 0.015-0.085″
Standard resolution: 0.030″
