3Dresyn PMMA-like, Polymethylmethacrylate like

High-stiffness transparent biocompatible 3D printing resin with PMMA-like mechanical behaviour and enhanced toughness.

Product description

3Dresyn® PMMA-like is a high-performance photopolymer engineered to replicate and exceed the properties of polymethyl methacrylate (PMMA), combining high stiffness, optical clarity and improved toughness. The material provides transparent to light orange finishes depending on formulation, printing and post-curing conditions, while maintaining excellent dimensional stability and ultra low water absorption. It is available in HV (higher mechanical performance) and LV (lower viscosity) versions for compatibility with SLA, DLP and LCD printing systems.

Intended use

Intended for professional use in vat photopolymerization (SLA, DLP and LCD) additive manufacturing.
Final suitability of printed parts must be validated by the user according to the specific application, processing conditions and applicable regulatory requirements.

Typical applications

• Transparent rigid engineering components
• Optical and light-transmitting parts
• High-stiffness housings and structural elements
• Medical and dental components requiring clarity and rigidity
• Functional prototypes requiring high dimensional stability

Material properties & test methods

Mechanical properties

• Flexural strength (break): 80–100 MPa (typical) (ISO 178)
• Tensile strength: <40 MPa (typical) (ISO 527-1 / ISO 527-2)
• Young’s modulus: 2.7–3.3 GPa (typical) (ISO 527-1 / ISO 527-2)
• Elongation at break: <6% (typical) (ISO 527-1 / ISO 527-2)
• Impact resistance (Notched Izod): moderate to high (typical for toughened PMMA-like systems)
• Shore hardness: D85–90 (ISO 868)

Thermal properties

• Glass transition temperature (Tg): >130 °C (typical)

Physical properties

• Color: clear to light transparent orange depending on formulation and post-processing
• Density: ~1.0–1.1 g/cm³ (typical)
• Water absorption: ultra low (ULWA, hydrophobic behaviour)
• Optical behaviour: high clarity with controlled transparency
• Shrinkage: very low (typical)

Biocompatibility & regulatory framework

• Biocompatible formulation platform
• Non-cytotoxic under validated conditions
• Biocompatibility must be evaluated on the final printed and post-processed device according to ISO 10993
• Manufacturing aligned with ISO 13485 quality management systems
• Organo-tin free formulation

Testing & processing disclaimer
Material properties are measured on printed and post-processed specimens and may vary depending on the selected material version, printer type, printing parameters, build orientation, post-curing conditions and test specimen preparation. Reported values are indicative and provided for reference only.

Printing & processing guidelines

• Printing technologies: SLA, DLP and LCD
• Wavelength range: 385–405 nm
