High-Precision Dental Model Resin 3160 for Orthodontics & Implants
The 3160 Dental Model Resin eliminates model warping, poor margin fits, and cast breakage across orthodontic, implant, and restoration workflows. Built with high heat deflection (120°C) and ultra-low shrinkage (<0.5%), it prevents distortion during high-temperature aligner thermoforming and guarantees true-to-CAD margin accuracy for crowns and surgical guides. Its high hardness (>82D) withstands repeated lab manipulation without chipping. By maintaining full-plate tolerances within 0.08 mm, this resin cuts reprint material waste, eliminates manual grinding time, and accelerates patient case turnarounds for dental labs and clinics.

Engineering Notes & Technical Interpretation
An engineering analysis of how key material specifications eliminate fitting errors and optimize daily dental laboratory production.
Why is a deformation temperature of 120°C critical for orthodontic applications?
Producing clear aligners requires thermoplastic sheets to be heated and vacuum-sucked over a printed model. If the resin's deformation temperature is too low, the heat from the plastic will cause the teeth on the model to shift or shrink. The 3160 resin’s 120°C threshold ensures the model remains rigidly locked in place, guaranteeing the resulting aligner applies the exact biomechanical forces prescribed by the orthodontist.
How does a shrinkage rate of < 0.5% impact lab profitability?
Photopolymers naturally shrink during the UV curing process. High shrinkage leads to models that are physically smaller than the digital design, causing crowns to fit too tightly and implant guides to misalign. By controlling shrinkage to under 0.5%, this resin ensures a true-to-CAD print. This eliminates the labor costs associated with technicians manually grinding restorations to fit, allowing a lab to increase its daily case output.
What is the manufacturing value of full-plate dimensional tolerance within 0.08 mm?
In high-volume dental labs, printers are often loaded with multiple models across the entire build plate. A tolerance variation greater than 0.1 mm can cause models on the edge of the plate to fail or fit poorly. By strictly controlling tolerance within 0.08 mm across the whole plate, the 3160 resin ensures unvarying batch consistency. You get the exact same precision whether you print one model in the center or twenty models edge-to-edge, heavily reducing scrap rates.
