3Dresyn OD-HT Hard & Tough Semi-Rigid Dental Resin

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.

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.

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

• Tensile strength: <30 MPa (ISO 527-1 / ISO 527-2)
• Flexural strength: <30 MPa (ISO 178)
• Young’s modulus: 1000–1500 MPa (ISO 527)
• Elongation at yield: <30% (ISO 527)
• Elongation at break: (ISO 527)
• Shore hardness: D60–70 (ISO 868)

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

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

• 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

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