3D printed dental mold
This dental mold was printed by Envisiontec using E-Denstone, a highly durable polymer. With 3D printing, it costs less to produce dental molds than it does with the traditional method, in which pliable latex is used to make impressions of teeth that are then sent to a third party that actually produces the mold. The 3D printing method is also twice as fast as the traditional method.
Invisalign, another dental mold company, uses 3D printing to make 17 million customized, transparent braces every year.
