Key Features & Advantages of Graphy TA-28 Clear Aligner Resin
-
True Direct-Print Capability
Unlike conventional thermoformed systems, Tera Harz TA-28 is specifically formulated for direct 3D printing, eliminating the need for thermoforming steps. This streamlined workflow reduces production time and enhances design flexibility.
-
Advanced Photopolymer Formula
Engineered with a density of ~1.091 g/cm³ and viscosity of 700±200 mPa·s, Tera Harz TA‑28 delivers consistent print quality and dimensional stability.
-
Exceptional Biocompatibility
Extensive research indicates that aligners printed with Tera Harz TA‑28 meet EN ISO 10993‑5 standards for non-cytotoxicity—even at increased layer thicknesses (up to 6 mm)—when properly UV cured for 20 minutes. Cell viability reductions remain below 30%, ensuring safe intraoral use.
-
Tailored Mechanical Performance
This resin supports variable layer thickness within a single aligner, ideal for integrating features such as embedded wire reinforcements or localized stiffness zones. This capability enhances force control and treatment efficacy compared to uniform-thickness thermoformed alternatives.
-
Shape‑Memory Potential
Building on Graphy’s Shape Memory Aligner (SMA) technology, Tera Harz TA-28 offers predictable tooth movement and improved treatment dynamics, streamlining orthodontic workflows.
Optimized Post‑Processing
To ensure maximum safety and performance:
-
Centrifugal Cleaning – Use Graphy’s Tera Harz Spinner for even resin removal.
-
UV Curing – Cure under nitrogen for 20 minutes to achieve full polymerization and biocompatibility, even with thicker prints.
-
Wash & Dry – Hot water rinse followed by thorough drying completes the process.
