3Dresyn Perfect Cast HS2 MF Bio, Heat Soluble, Meltable, Flowable & Castable photopolymer bio based liquid 3D resin

3Dresyn® Perfect Cast HS2 MF Bio is a heat-soluble, meltable, flowable and castable bio-based and monomer-free liquid photopolymer developed for direct investment casting workflows using heated top-down and bottom-up SLA, DLP and LCD printers.

The material behaves as a viscous liquid before printing and transforms into a flexible thermoplastic solid after curing, capable of melting or thermally degrading during burnout to enable clean elimination and defect-free casting.

Designed for use in heated vat photopolymerization systems (top-down and bottom-up SLA, DLP and LCD). Requires controlled temperature conditions during printing to ensure optimal viscosity, flow and printability.

• Direct investment casting (DC)
• Wax-like sacrificial casting patterns
• Fine-detail and thick casting geometries
• Applications requiring meltable or thermally degradable patterns

• Young’s modulus: <60 MPa (ISO 527)
• Elongation: <1–2% (ISO 527)
• Shore hardness: D60 (ISO 868)

• Density: 0.90–1.20 g/cm³, depending on formulation and, where applicable, selected version (ISO 1675)

• Heat deflection temperature: ~25–30 °C @ 0.45 MPa (ISO 75)
• Melting temperature range after curing: >100–200 °C (workflow dependent) (ISO 11357-3)

• Thermoplastic behavior after printing
• Tensile and flexural strength: <4 MPa (ISO 178)
• Very low shrinkage (<1%)
• Residual ash content: 0% (ISO 3451-1)

• Flows like molten wax upon heating after printing
• Gravity-assisted elimination from the mold
• Excellent burnout without imperfections, even with standard gypsums
• Compatible with both filigree and thick geometries
• Flexible thermoplastic behavior during processing
• Soluble in acetone

• <90,000 mPa·s at 25 °C: poor flow, non-printable
• <30,000 mPa·s at 30 °C: limited flow, top-down only
• <10,000 mPa·s at 35 °C: printable with controlled conditions
• <7,000 mPa·s at 40 °C: good flow, suitable for most systems
• <2,500 mPa·s at 45 °C: optimal flow and reduced stickiness
• <800 mPa·s at 60 °C: excellent flow but reduced structural stability
• <400 mPa·s at 65 °C: very high flow, risk of deformation in fine features

• Printing technologies: SLA, DLP and LCD (top-down and bottom-up)
• Cyan version is recommended for increased dimensional accuracy vs clear version
• Requires heated printing conditions
• Recommended printing temperature: 40–50 °C or higher
• Monomer-free formulation as supplied
• Bio-based from renewable resources: >75–80%
• Organo-tin free formulation
• Improved printability compared to 3Dresyn® Perfect Cast HS1 Bio

Depending on formulation tuning, exposure energy and post-curing conditions, the material may melt or thermally degrade during burnout. In both cases, complete elimination and defect-free casting can be achieved.

• Follow 3Dresyns Instructions for Use (IFU)
• Typical exposure: 10–25 seconds for 50 µm layers depending on printer power
• Higher temperature reduces viscosity but also reduces green strength
• Use dense and robust supports to prevent deformation
• Excessive exposure may reduce melt flow and cause rubber-like degradation instead of melting

• Clean parts using warm Cleaning Fluid UNW2 Bio

• Post-curing is not required
• Optional light post-curing increases melting temperature
• Excessive post-curing may reduce melt flow behavior

• Suitable for gypsum and phosphate investments
• Position upside down for molten elimination by gravity
• Final burnout ensures complete ash-free removal

Material performance depends on printer type, temperature control, exposure conditions, cleaning, post-curing, investment material and burnout cycle. Full workflow validation is required.

• Heat-soluble and meltable wax-like casting system
• Compatible with both top-down and bottom-up printers
• Improved printability vs HS1 solid wax system
• Excellent burnout with zero ash content
• Bio-based and monomer-free formulation
• Wide processing window via temperature control
• Suitable for both fine and thick geometries
• Advanced casting flexibility (melting or thermal degradation)

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