Dental Resin is a photosensitive polymer designed specifically for dental applications, belonging to the SLA/LCD/DLP vat photopolymerization family of 3D printing materials. Its foremost characteristic is mandatory biocompatibility, allowing safe use in oral diagnosis, treatment, and dental model production, making it a key material in the digital orthodontic and restorative workflow.
Dental resins are categorized by application into dental model resins (orthodontic models, restorative models) and direct-print resins (crowns, bridges, temporary prostheses). Core requirements include biocompatibility (compliance with ISO 10993), high precision (±0.05mm), dimensional stability, and low shrinkage. The material system is primarily methacrylate-based, with bio-based components added to reduce toxicity. In clear aligner applications, the workflow of 3D printing a dental model → thermoforming a clear aligner with a vacuum press → demolding → trimming and polishing → patient wear enables customized and batch production.
Complies with ISO 10993 standards, safe for dental diagnosis, treatment, and oral-related applications.
Forming precision reaches ±0.05mm, finely reproducing tooth and gingival anatomy.
Low-shrinkage formulation keeps printed models dimensionally stable, ensuring thermoforming and restorative accuracy.
Bio-based components reduce toxicity and odor, improving handling and use safety.
Complies with ISO 10993 standards, safe for dental models and oral treatment-related applications.
Forming precision reaches ±0.05mm, finely reproducing tooth, gingival, and occlusal details.
Low-shrinkage formulation keeps printed models dimensionally stable, ensuring thermoforming and restorative accuracy.
Compatible with rapid vat photopolymerization, enabling batch production of dental models and aligner models in a short time.
Good edge stability and easy separation from thermoforming materials improve post-processing efficiency.
Intraoral scanning → CAD design → 3D printing → post-processing → clinical use, fully digital end-to-end.
Bio-based components reduce odor, improving the operating environment and use safety.

| Characteristic | Description | Impact |
|---|---|---|
| Requires Biocompatibility Certification | Must comply with ISO 10993 and other biocompatibility standards; high certification threshold | High R&D and compliance costs limit the number of suppliers |
| Not for Direct Oral Contact | Dental model resins are mainly for model production, not for long-term intraoral wear of directly printed dentures | Direct printing of dentures or crowns requires higher-grade direct-print resins |
| High Equipment Precision Requirements | Requires high-resolution vat photopolymerization printers to achieve ±0.05mm precision | Higher equipment investment; entry-level printers may not meet requirements |
| Strict Storage Conditions | Photosensitive resins must be stored away from light and are sensitive to temperature | High storage and logistics requirements; expired or degraded resin affects precision |
| Fine Post-Processing Required | Cleaning, post-curing, and thermoforming workflows must be strictly controlled to maintain precision | Non-standard processes may cause model deformation and affect aligner fit |
