3Dresyn LMM Perfect Cast PC3, castable solid photopolymer for printing (non heat meltable after printing) castings for Jewelry by Lithography-based Metal Manufacturing LMM

Product description

3Dresyn® LMM Perfect Cast PC3 is a non-heat meltable after printing castable solid photopolymer developed for printing high-detail castable patterns for jewelry by Lithography-based Metal Manufacturing (LMM).

Application framework

Designed for use in LMM systems within controlled professional environments. Suitable for Direct Investment Casting (DC) workflows requiring ultra-high detail, clean burnout and dimensional precision without melting behavior during thermal processing.

Typical applications

• Jewelry casting patterns
• Direct investment casting (DC)
• Ultra-fine filigree structures
• High precision decorative components
• Complex geometries requiring dimensional stability

Measured mechanical properties

• Residual ash content: <0.0001% (internal method)
• No shrinkage during 3D printing (internal method)
• No expansion during burn-out (internal method)
• Process-dependent viscosity before printing (Brookfield)

Functional performance characteristics

• Photoreactive spreadable butter-like paste with viscosity decrease upon heating before printing
• Non-meltable after printing behavior for controlled thermal degradation
• Ideal for Direct Investment Casting (DC)
• Excellent burn-out without imperfections even with low-cost gypsums
• Negligible residual ash content (<0.0001%)
• Water cleanable (no isopropanol required)
• No shrinkage during printing and no expansion during burn-out
• Excellent resolution and dimensional precision
• Monomer-free formulation for safe handling
• No toxic pictograms
• Organo-tin free
• Does not present reproductive toxicity concerns associated with competitor resins

Processing and handling performance

• Available in magenta, cyan, yellow and natural white colors
• Printable with LMM printers
• No post-curing required

Cleaning

• Prints can be decaked by melting at 40 °C the uncured resin
• Rinse parts thoroughly under warmed water and allow to dry completely

Post-curing

• Light post-curing is not required

Investment casting

Burnout process:

• Insert flask in the preheated oven at 200 °C
• Ramp 2 °C/min up to 550 °C
• Hold at 550 °C for 30 minutes
• Ramp 2 °C/min up to 720 °C
• Hold at 720 °C for 120 minutes
• Ramp −2 °C/min down to 640 °C
• Cast molten metal inside the mold using centrifuge or vacuum casting equipment

Testing & processing disclaimer

Material performance depends on printer type, exposure conditions, geometry, investment material and burn-out cycle. Full validation is required for each specific casting workflow.
