3Dresyn LMM Perfect Cast PC1, castable solid photopolymer for printing heat meltable castings for Jewelry by Lithography-based Metal Manufacturing LMM

Product description

3Dresyn® LMM Perfect Cast PC1 is a heat-soluble / meltable, flowable and castable solid photopolymer developed for printing high-resolution castable patterns for jewelry using Lithography-based Metal Manufacturing (LMM).

Application framework

Designed for use in LMM systems within controlled professional environments. Suitable for the fabrication of high-detail castable patterns requiring clean burnout, zero ash residue and complete material elimination for precision investment casting workflows.

Typical applications

• Jewelry casting patterns
• Filigree and ultra-fine detailed structures
• Investment casting for precious metals
• Complex geometries requiring full burnout
• High-precision decorative and technical castings

Measured mechanical properties

• Melting point before printing: 32 °C (internal method)
• Melting point after printing and post-curing: 47 °C (internal method)
• Tensile and flexural strength: <5 MPa (ISO 527 / ISO 178)
• Young’s modulus: <800 MPa (ISO 527)
• Elongation: <2% (ISO 527)
• Very low viscosity: <100 cps at 35 °C (Brookfield)
• No shrinkage during printing (internal method)

Functional performance characteristics

• Photoreactive spreadable butter-like paste for LMM printing
• Melts at 32 °C before printing and flows like molten wax after printing
• 100% removal from the investment mold by gravity in upside-down position
• 0% residual ash content after burn-out
• Non-rubbery behavior during heating (unlike conventional resins)
• Excellent burnout even with low-cost gypsum investments
• No expansion during burn-out
• Reduced brittleness compared to standard wax-like materials
• Very high resolution suitable for filigree geometries
• Bio-based from renewable resources (>70% bio content)
• Safe formulation without toxic pictograms
• Organo-tin free

Processing and handling performance

• Supplied in cyan, magenta, yellow, black and white colors
• Printable with LMM printers
• Typical exposure times:
  • 20–25 seconds for 50 µm layers with low power <1 mW/cm² LMM printers
  • 10–15 seconds for 50 µm layers with medium power 1–2 mW/cm² LMM printers
  • <10 seconds for 50 µm layers with high power 5–15 mW/cm² LMM printers

Instructions for use (IFU) for LMM printers

Cleaning

• Prints can be decaked by melting at 35 °C the uncured resin
• Rinse parts thoroughly under warmed water at 33–34 °C and allow to dry completely

Post-curing

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

Investment casting

• Material melts completely above 47 °C allowing full gravity removal
• Compatible with gypsum and phosphate investments
• Enables clean burnout without defects

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.
