Description
Graphy TA-28 is an advanced photopolymer resin engineered for the direct 3D printing of clear orthodontic aligners. It enables the creation of precise, crystal-clear, and biocompatible aligners that maintain consistent orthodontic forces through its patented shape memory technology. This resin eliminates the need for traditional thermoforming processes, simplifying fabrication while improving patient comfort and treatment effectiveness.
Key Benefits
-
Direct 3D Printing: Streamlines aligner production by removing thermoforming steps.
-
Shape Memory Polymer: Ensures aligners fit snugly and retain effective force over time.
-
Exceptional Clarity: Produces nearly invisible aligners with superior transparency.
-
Biocompatible & Safe: Certified by CE, FDA, and KFDA for medical device safety.
-
Customizable Thickness: Supports variable thickness to optimize orthodontic force distribution.
-
Durable & Flexible: Resistant to cracking and deformation, offering long-lasting performance.
