• Medium impact and shattering resistance
• Very high resolution with fine feature capability

High Heat Deflection Temperature (HDT) photopolymer resins, despite their rigidity, may exhibit brittle behavior and reduced lifetime under prolonged thermal exposure. For applications requiring long-term durability at high temperatures, alternative materials such as machined polyimide, or injection-molded PolyAmide Imide (PAI) or similar high-performance polymers, should be considered.

• Printing technologies: SLA, DLP and LCD
• Compatible with most commercial and professional systems when properly calibrated
• Increased durability of the resin tank during printing

• Biocompatible (final part validation required)
• Synthetic resin base
• Organo-tin free formulation

Material properties are measured under controlled laboratory conditions and may vary depending on printer type, exposure conditions, layer thickness, build orientation and post-processing workflow.

This material is supplied as a professional manufacturing material for engineering and prototyping workflows. It is not marketed as a finished product. Final part performance and suitability must be validated by the user according to the intended application.
