Dental Model Resin grades and fills
Dental Model Resin is supplied in 4 conditions, soft to hard.
Compare all 4 grades and fillsHide
| Grade · open for datasheet | Best for | Yield MPa | Tensile MPa | Elong. % | Hardness |
|---|---|---|---|---|---|
High-speed / high-throughput model resin | Use the high-speed resin for large orthodontic model runs where short layer exposure and thicker layers raise throughput, accepting slightly lower accuracy and 48 MPa tensile strength. | 44 | 48 | 6 | 83 Shore D |
Ceramic/mineral-filled high-stiffness model resin | Pick the ceramic/mineral-filled resin for dies, occlusal adjustment and repeated thermoforming: 4.6 GPa modulus and 70 °C service, but it is brittle at 2% elongation and the vat needs stirring. | 60 | 2 | 90 Shore D | |
Orthodontic / thermoforming model resin | Choose the thermoforming grade for clear-aligner pressing, where 70 °C heat-distortion resistance and sharp margins come first and the formulation tolerates repeated forming cycles. | 60 | 4 | 87 Shore D | |
High-precision / low-shrinkage model resin | Choose the fine-detail grey resin for dies and implant or orthodontic measurement models needing ±50 µm accuracy; shrinkage and post-cure movement are minimal but elongation is only 3.5%. | 65 | 3.5 | 88 Shore D |

What is Dental Model Resin?
Dental Model Resin is a stiff, low-shrinkage photopolymer for SLA/DLP/LCD printing, formulated for dimensional accuracy in dental study and orthodontic models rather than for direct oral contact. It is used by labs and clear-aligner producers and is available in STD, HP, FAST, FILLED, ORTHO and BIO-CERT versions. Cured values are 58 MPa tensile strength, 5% elongation, 2.4 GPa modulus, 85 Shore D and service to 55 °C. Accuracy depends on complete post-cure and on dark, dry storage, since under-cured parts drift dimensionally and retain residual monomer; for intraoral or bone-contact parts use a certified Surgical Guide Resin. Dental Model Resin has a density of 1.18 g/cm³ (0.0426 lb/in³), heavier than 50% of polymer grades. Its glass-transition temperature is 78°C (172 °F). Dental Model Resin has a tensile strength of 58 MPa (8.41 ksi), stronger than 66% of polymer grades. Elongation at break is 5% and the elastic modulus is 2.4 GPa (0.348 Msi).

Working with Dental Model Resin
Is Dental Model Resin easy to machine?
Cured parts can be trimmed with small high-speed cutters or dental tungsten-carbide burs at light feed; the material is brittle and chips at edges, and dry grinding softens it through local heating, so work at low speed with dust extraction.
Can Dental Model Resin be welded?
Thermoset and not heat-weldable; join model sections by spotting on the same resin and curing under a 405 nm lamp, or bond with cyanoacrylate adhesive.
Can Dental Model Resin be formed, bent or molded?
Printed on SLA/DLP/LCD at 50–100 µm layers with the vat at 25–30 °C; after printing, wash 3–5 min in IPA, blow dry, then post-cure 5–20 min at 405 nm — under-curing causes dimensional drift and residual monomer.

Limits by weight percent from the governing specification, written the way the spec states them — a single maximum for impurities, a range for alloying elements, and the base element as balance. Nominal is the typical mid-range value.

What surface finishes work on Dental Model Resin?
Bead blasting or abrasive sanding gives a matte model surface; painting and plating are not recommended. Store models dry and away from light to prevent post-shrinkage and yellowing.

Dental Model Resin — frequently asked
What is Dental Model Resin used for?
Dental Model Resin is typically used for orthodontic study models, denture cast models and clear aligner molds. In short: high-accuracy dental models; low print shrinkage; not for intraoral use.
What is the tensile strength of Dental Model Resin?
Dental Model Resin has a typical tensile strength of 58 MPa (8.41 ksi) — stronger than 66% of polymer grades. Strength varies by condition: see the 4 listed tempers.
Is Dental Model Resin easy to machine?
Reasonably — machinability is rated good (55/100, worse than 64% of polymer grades). Cured parts can be trimmed with small high-speed cutters or dental tungsten-carbide burs at light feed; the material is brittle and chips at edges, and dry grinding softens it through local heating, so work at low speed with dust extraction.
Can Dental Model Resin be welded?
Not readily — weldability is rated not recommended (5/100). Thermoset and not heat-weldable; join model sections by spotting on the same resin and curing under a 405 nm lamp, or bond with cyanoacrylate adhesive.

Dental Model Resin is rated for continuous use to about 55°C (131 °F), and briefly to 80°C. Strength falls off well before that limit — check the elevated-temperature data for load-bearing parts.
