3Dresyn IM-UHT durable, ultra hard and tough for injection at medium high temperature

Product description

3Dresyn® IM-UHT is an ultra hard and tough mold-making photopolymer developed for the fabrication of durable molds intended for injection of medium-high melting temperature materials.

Application framework

Designed for use in vat photopolymerization systems (SLA, DLP and LCD) within controlled professional environments. Suitable for the fabrication of ultra-rigid molds for demanding molding workflows requiring high rigidity, dimensional stability and elevated thermal resistance.

Typical applications

• Durable molds for medium-high temperature injection
• Molds for engineering thermoplastics
• Rigid technical tooling
• High precision molds requiring high stiffness
• Advanced molding workflows requiring high dimensional stability

Measured mechanical properties

• Shore hardness: D90 (ISO 868)
• Tensile strength: 65–70 MPa (ISO 527)
• Young’s modulus: >3500 MPa (ISO 527)
• Elongation: <3% (ISO 527)
• Heat deflection temperature: up to 170 °C @ 0.45 MPa (subject to post-cure) (ISO 75)
• Very low viscosity: <300 cps (Brookfield)

Functional performance characteristics

• Recommended for injection of medium-high melting temperature materials
• Ultra hard and tough UHT behavior
• Ultra rigid with minor unavoidable brittleness for its rigidity
• Very high printing resolution down to 20 µm
• Very low shrinkage

Processing and handling performance

• Printable by most commercial and professional SLA, DLP and LCD 3D printers
• Increased durability of the resin tank
• Organo-tin free

Testing & processing disclaimer

Material performance depends on printer type, exposure conditions, mold geometry, post-curing conditions and molding workflow. Final mold performance and service life must be validated under the intended application conditions.
