3Dresyn BRS R1, for printing biocompatible rigid scaffolds

Product description

3Dresyn® BRS R1 is a rigid biocompatible photopolymer developed for scaffold fabrication and bioprinting applications requiring higher stiffness, controlled degradation behavior and partial bioabsorbability.

Application framework

Designed for use in vat photopolymerization systems (SLA, DLP and LCD) and compatible bioplotting systems with UV/Visible curing units within controlled professional environments. Suitable for research and development in tissue engineering, rigid scaffold fabrication and biocompatible device prototyping.

Important regulatory note

This material is partially bioabsorbable, not fully bioabsorbable. Degradation, resorption and biological response depend on geometry, curing conditions, post-processing and application environment. Final biocompatibility and bioabsorption performance must be validated by the user according to applicable regulatory frameworks (e.g. ISO 10993).

Typical applications

• Rigid 3D printed scaffolds for tissue engineering research
• Bioprinting structures requiring higher stiffness
• Bioactive composite scaffolds
• Biocompatible prototyping of medical research devices
• 2D and 3D bioprinting systems

Measured mechanical properties

• Shore hardness: D70 (ISO 868)
• Flexural strength: <10 MPa (ISO 178)
• Young’s modulus: <1000 MPa (ISO 527)
• Elongation: <10% (ISO 527)
• Very low shrinkage (internal method)

Functional performance characteristics

• Hard and rigid resin after curing
• 100% biocompatible resin without toxic risk pictograms (when fully cured and properly processed)
• Similar properties but slower biodegradation and bioabsorption than 3Dresyn® Bio Scaffolds1, 2, 3 & 4
• Ultra pure and safe, non-cytotoxic once fully cured and cleansed
• 100% solids formulation
• Bio-based from renewable resources (>75% bio content)
• Biocompatible, biodegradable and partially bioabsorbable
• Low-medium hardness and toughness with increased rigidity
• Very high resolution
• Very low shrinkage
• Organo-tin free formulation

Processing and handling performance

• Printable by most commercial and professional SLA, DLP and LCD printers
• Compatible with bioplotters using UV/Visible curing units
• Increased durability of the resin tank

Processing note

Biocompatibility and degradation behavior are strongly dependent on post-processing (cleaning, post-curing) and final part geometry. Incomplete curing or insufficient cleaning may result in cytotoxic effects.

Testing & processing disclaimer

Material performance, biocompatibility, biodegradation and bioabsorption depend on printer type, exposure conditions, geometry, post-processing and application environment. Full validation according to relevant standards (e.g. ISO 10993 series) is required for each specific application.

Regulatory & legal notice

This material is supplied as a professional R&D material and is not marketed as a finished medical device. It is not certified for implantation. Final biocompatibility, degradation, bioabsorption and regulatory compliance remain the responsibility of the user.
