3Dresyn OD-HT “Hard & Tough” – Semi-Rigid Dental Photopolymer for Laboratory Fabrication Workflows

Product description

3Dresyn OD-HT is a versatile hard and tough photopolymer formulation developed for professional dental laboratory workflows requiring semi-rigid performance, dimensional stability and controlled flexibility depending on thickness.

Application framework

Intended for use in vat photopolymerization systems (SLA, DLP and LCD) for the fabrication of dental laboratory components such as copings, orthodontic bonding trays, prosthodontic and orthodontic models, and other auxiliary elements used in controlled professional environments.

Typical applications

• Copings
• Orthodontic bonding trays
• Prosthodontic models
• Orthodontic models
• Auxiliary laboratory elements

Measured mechanical properties

• Tensile strength: <30 MPa
• Flexural strength: <30 MPa
• Young’s modulus: 1000–1500 MPa
• Elongation at break: (ISO 527)
• Shore hardness: D60–70
• Elongation at yield: <30%

Measured physical properties

• Viscosity: <4000 mPas at 23°C ± 2°C (ISO 3219)
• Shrinkage: very low

Functional performance characteristics

• Hard and tough semi-rigid behavior
• Good dimensional stability
• Durable under laboratory handling
• Very low shrinkage
• Organo-tin free

Thickness-dependent mechanical behavior

• Thin sections (0.2–0.3 mm): suitable for flexible coping-type components and bonding tray applications
• Medium sections (1–2 mm): semi-rigid performance for model-based workflows
• Thick sections (>2 mm): rigid structural behavior for laboratory tooling and model applications

Processing and handling performance

• Printable on most commercial and professional SLA, DLP and LCD 3D printers
• Increased durability of the resin tank

Chemical and safety characteristics

• Organo-tin free
