3Dresyn IM-UHR-WS High-Resolution Water-Soluble Sacrificial Resin

3Dresyn® IM-UHR-WS is a water-soluble ultra-high resolution photopolymer developed for the fabrication of precision single-use sacrificial molds and micro-detailed components requiring very fine feature definition and controlled dissolution in advanced molding and casting workflows.

Designed for use in vat photopolymerization systems (SLA, DLP and LCD) within controlled professional environments. Suitable for high resolution sacrificial mold fabrication and micro-scale applications requiring exceptional dimensional accuracy, fine feature reproduction and clean post-process dissolution. This material is intended for single-use applications where the mold is removed after processing.

• Designed for single-use sacrificial mold fabrication
• Suitable for precision casting and micro-molding workflows
• Fast water solubility
• High dimensional accuracy and feature fidelity
• Broad compatibility with SLA/DLP/LCD printers

This material is supplied as a professional manufacturing material and is not marketed as a finished product. It is intended for use as a sacrificial tooling material. Final molding or casting performance, dissolution behavior and process validation remain the responsibility of the user depending on printer, mold design and processing workflow.
