Clear Resin v4.1 produces smooth, transparent, and accurate parts that are widely used across industries. It supports applications where visual inspection, light transmission, or fluid flow analysis are required, while maintaining the strength and precision expected from an SLA material.

This material is trusted for medical device development, optical models, fluid systems, and consumer products that benefit from a clean, high-quality finish. Clear Resin v4.1 is a versatile choice for both functional prototypes and production-ready parts where transparency and fine detail matter.

Key Benefits

  • Transparent Appearance – Enables visualization of internal features, light paths, and fluid flow.

  • High Resolution – Produces smooth surfaces and fine details with SLA precision.

  • Versatile Performance – Suitable for both prototypes and functional end-use parts.

  • Dimensional Accuracy – Reliable tolerances for complex and detailed geometries.

  • Visual Validation – Ideal for models where clarity and part inspection are critical.

  • Versatility – Trusted across consumer, medical, and engineering applications.

Applications

  • Transparent housings and enclosures – Product casings where visibility of internal components is important.

  • Concept models with a clear finish – Design validation, client presentations, and models where appearance matters.

  • Medical and research visualization – Inspection of internal features in surgical guides, educational models, and device development.

  • Fluidic devices and flow models – Microfluidics, manifolds, and lab equipment requiring flow observation.
