3Dresyn IM-SF Cocoon MF Bio - Monomer-Free Bio-Based Soft Sacrificial Resin

3Dresyn® IM-SF Cocoon MF Bio is a soft and flexible monomer-free (MF) sacrificial photopolymer designed for the fabrication of cocoon-type molds intended for manual removal after casting of soft materials.

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.

• Soft flexible cocoon sacrificial molds
• Molds for wax and RTV silicone injection
• Otoplastic and hearing aid workflows
• Sacrificial tooling for soft materials

• Shore hardness: A90 (ISO 868)
• Low tensile strength (ISO 527 indicative)
• Very low shrinkage: <1% (internal method)
• High resolution: up to ~20 µm (process-dependent)

• 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
• Very low viscosity: <50 mPa·s (internal method)

• Soft and flexible mechanical response
• Controlled mechanical fragmentation without damaging soft casts
• Non-water-soluble sacrificial system
• Optimized for cocoon wall thickness ~1 mm
• Suitable for injection of waxes and RTV silicones

• Printable with most commercial and professional SLA, DLP and LCD 3D printers
• Monomer-free (MF) formulation
• Bio-based resin system
• Organo-tin free

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.

• Soft flexible sacrificial cocoon system for delicate applications
• Optimized for thin wall cocoon molds (~1 mm)
• Monomer-free and bio-based formulation
• High resolution with very low shrinkage
• Compatible with SLA, DLP and LCD technologies

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