3Dresyn Perfect Cast HS1 Bio, Heat Soluble, Meltable, Flowable & Castable photopolymer bio based solid wax

3Dresyn® Perfect Cast HS1 Bio is a heat-soluble, meltable, flowable and castable bio-based solid wax photopolymer developed for direct investment casting workflows using top-down SLA and DLP printers. The material is supplied as a solid photoreactive resin that melts before printing and, once printed and post-cured, can be fully eliminated from the investment mold by gravity due to its very low melt viscosity.

The formulation is designed for controlled wax-like casting workflows requiring full mold evacuation, negligible ash content and bio-based content from renewable resources.

Designed for use in top-down vat photopolymerization systems (SLA and DLP) with precise temperature control of the resin and printing environment. Suitable for direct investment casting workflows under controlled laboratory or production conditions.

• Direct investment casting (DC)
• Wax-like sacrificial casting patterns
• Relatively thick casting geometries
• Applications requiring full gravity elimination of the pattern before burnout

• Young’s modulus: <800 MPa (ISO 527)
• Elongation at break: <2% (ISO 527)

• Printing shrinkage: no measurable dimensional shrinkage after calibration under validated processing conditions
• Very low viscosity: <100 cps at 35 °C

• Melting point as supplied before printing: 32 °C (ISO 11357-3)
• Melting point after printing and post-curing: 47 °C (ISO 11357-3)
• Tensile and flexural strength: <2 MPa (ISO 178)
• Residual ash content: 0% (ISO 3451-1)
• No shrinkage during 3D printing
• No expansion during burnout

• Melts and flows like molten wax after printing and post-curing
• 100% elimination by gravity from the investment mold in upside-down position
• Excellent burnout without casting imperfections, even with low-cost gypsums
• Reduced brittleness for a wax-like material
• Non-rubbery behavior upon heating compared with conventional castable photopolymers
• Ideal for relatively thick prints rather than ultra-filigree fine-detail patterns
• 3Dresyn® Perfect Cast WS1 for water- and steam-soluble casting workflows
• 3D resins for printing durable molds
• 3Dresyn® IM-HF and 3Dresyn® IM-F for injection of 3Dresyns waxes or traditional waxes
• Cocoon sacrificial 3D resins
• 3Dresyn® IM-SF Cocoon and 3Dresyn® IM-SF Cocoon MF Bio
• Water soluble sacrificial 3D resins for injection of 3Dresyns waxes or traditional waxes

• 3Dresyn® Perfect Cast HPP for high power printers (monochrome LCD, DLP and laser printers)
• Direct printing of water-soluble sacrificial resins:

• Wax injection in durable 3D printed molds (for non-intertwined mold geometries):
• Wax injection in easy-breaking cocoon sacrificial molds (for intertwined mold geometries):
• Wax injection in water-soluble sacrificial molds (for intertwined mold geometries):

• Top-down SLA and DLP printing only
• Printable with temperature-controlled top-down printers at 33–34 °C
• Cyan version is recommended for increased dimensional accuracy vs clear version
  
• Prints can be cleaned in warm water at 33–34 °C to melt uncured resin from the surface
• Post-curing in air or water in a light box for 30–60 minutes is recommended to increase curing and melting point up to 47 °C
• Organo-tin free formulation
• Direct printing of castable sacrificial resins:
• 3Dresyn® Perfect Cast LPP for low power multicolor LCD printers

Warning: this material is recommended only for professional top-down printers because precise and homogeneous temperature control is crucial for successful printing. If the temperature is too high (above 35 °C), prints may melt during printing. If the temperature is too low (below 33 °C), the liquid resin may solidify around the prints. Constant temperature in both the resin tank and build platform is essential.

• Exposure times 20–25 seconds for 50 µm layers with low power (<1 mW/cm²) printers
• Exposure times 10–15 seconds for 50 µm layers with medium power (1–2 mW/cm²) printers
• Exposure times <10 seconds for 50 µm layers with high power (5–15 mW/cm²) printers

• Bio-based from renewable resources: >70% bio content
• Monomer-free as supplied

• 3Dresyn® Perfect Cast HS1 Bio is solid at room temperature
• Warm the material before printing to 33.5 °C
• Warm the bottle in a water bath or oven until fully melted
• Once liquid, pour into the resin tank and keep the resin at 33.5 °C
• Allow 15–30 minutes for full temperature stabilization before printing
• Stir the material well before printing to verify complete liquefaction

• Rinse printed parts thoroughly under warm water at 33–34 °C
• Allow parts to dry thoroughly after cleaning

• Post-cure for 30–60 minutes in a light box
• Post-curing increases curing level and melting point up to 47 °C

• Since the material melts completely above 47 °C, any gypsum or phosphate investment can be used
• The material is fully eliminated by gravity in upside-down position

Material performance depends critically on precise temperature control, printer type, exposure conditions, cleaning procedure, post-curing conditions, investment material and burnout cycle. Full workflow validation is required for each specific application.

• Heat-soluble and meltable wax-like castable system
• 100% gravity elimination from the mold for ash-free burnout
• Bio-based formulation with >70% renewable content
• Excellent burnout even with low-cost gypsums
• Reduced brittleness compared with conventional wax-like systems
• Designed for advanced top-down casting workflows

This material is supplied as a professional manufacturing material and is not marketed as a finished product. Final casting performance, melting behavior, burnout behavior and process validation remain the responsibility of the user depending on printer, temperature control, investment material and casting workflow.
