3Dresyn® IM-S&C1 Cocoon MF Bio is a soft and crispy monomer-free (MF) sacrificial photopolymer developed for the fabrication of cocoon-type molds designed for easy manual breakage after casting of soft materials.



3Dresyn IM-S&C1 Cocoon MF Bio - Monomer-Free Soft & Crispy Sacrificial Resin
Product description
Application framework
Designed for use in vat photopolymerization systems (SLA, DLP and LCD) within controlled professional environments. Suitable for the fabrication of non-water-soluble sacrificial cocoon molds for soft material injection workflows.
Typical applications
- Soft & crispy cocoon sacrificial molds
- Molds for medical-grade RTV silicone injection
- Otoplastic and hearing aid manufacturing workflows
- Sacrificial tooling for flexible and soft materials
Mechanical properties
- Shore hardness: A70 (ISO 868)
- Low tensile strength (ISO 527 indicative)
- Very low shrinkage: <2% (internal method)
- High resolution: up to ~20 µm (process-dependent)
Physical properties
- Density: 0.90–1.20 g/cm³, depending on formulation and, where applicable, selected version (ISO 1675)
- Printing shrinkage: no measurable dimensional shrinkage after calibration under validated processing conditions
- Low viscosity: <100 mPa·s (internal method)
Functional performance characteristics
- Soft and crispy behavior for easy manual breakage
- Non-durable fragmentation into small pieces without damaging soft casts
- Non-water-soluble sacrificial system
- Optimized for cocoon wall thickness >2 mm
- Suitable for injection of soft materials such as RTV silicones
Processing and handling performance
- Printable with most commercial and professional SLA, DLP and LCD 3D printers
- Monomer-free and biocompatible formulation
- Bio-based from renewable resources
- Increased durability of the resin tank
- Organo-tin free
Testing & processing disclaimer
Material performance depends on printer type, exposure conditions, mold geometry and casting workflow. Breakage behavior and final results must be validated under the intended application conditions.
