3Dresyn IM-HDT-WS, high deflection temperature and water soluble for very high temperature sacrificial injection molding

Product description

3Dresyn® IM-HDT-WS is a water-soluble sacrificial mold-making photopolymer developed for the fabrication of injection molds intended for very high injection pressure and temperature materials, including plastics, ceramics (CIM) and metals (MIM).

Application framework

Designed for use in vat photopolymerization systems (SLA, DLP and LCD) within controlled professional environments. Suitable for the fabrication of water-soluble sacrificial injection molds for advanced molding workflows requiring high rigidity, dimensional stability and controlled dissolution behavior.

Typical applications

• Water-soluble sacrificial injection molds
• Molds for high pressure and high temperature plastic injection
• Molds for ceramic injection molding (CIM)
• Molds for metal injection molding (MIM)
• Thin-wall sacrificial molds requiring high rigidity and fast dissolution

Measured mechanical properties

• Shore hardness: D85 (ISO 868)
• Heat deflection temperature (HDT): <160 °C @ 0.45 MPa (ISO 75)
• Tensile and flexural strength: <40 MPa (ISO 527 / ISO 178)
• Young’s modulus: >3000 MPa (ISO 527)
• Elongation: <2% (ISO 527)
• Viscosity: <100 mPas at 23°C ± 2°C (ISO 3219)
  

Functional performance characteristics

• Fast solubility in water
• Tack-free finishes after light box post-curing
• Very high rigidity to permit printing of thin rigid mold walls for maximum solubility speed and minimum resin consumption
• Non-brittle at injection temperatures
• High resolution once tuned to printer specifications and after full workflow implementation
• Very low shrinkage

Processing and handling performance

• Printable with most commercial and professional SLA, DLP and LCD 3D printers
• Supplied in clear, cyan, magenta, yellow, black and white colors
• Cyan, magenta, yellow and especially black provide higher resolution than clear and white
• Improved water solubility is achieved with low light power printers, such as standard LCD printers
• Increased durability of the resin tank
• Metal- and organo-tin free formulation
• It can crystallise at temperatures below 15–20 °C
• Warm to 60 °C to dissolve crystals before use
• Recommended printing temperature: 20–25 °C
• Clean and post-cure 3D prints with Cleaning Fluid WS1 Bio
• Level of printing difficulty: medium

Processing note

Soluble materials may swell instead of dissolve in some printing settings, especially when they are cured at high relative power such as with high power laser and DLP printers.

Testing & processing disclaimer

Material performance depends on printer type, exposure conditions, mold geometry, dissolution conditions and full workflow implementation. Parameters must be validated by the user for each specific application.
