Beginning as a small orthodontic laboratory in 1964, Nice Lakes now designs, develops, manufactures, and markets greater than 4000 services to be used within the orthodontic, dental, and sleep/airway market.

The corporate has been a long-time adopter of additive manufacturing, initially utilizing the expertise over ten years in the past. Nice Lakes has invested in PolyJet, DLP, and SLS 3D print applied sciences in their very own services, and can also be a reseller for Stratasys and 3D Techniques dental options. Though the agency has efficiently built-in additive manufacturing into its workflow, finishing the method chain with post-printing options has confirmed troublesome. 

Since dental home equipment are custom-manufactured on a case-by-case foundation, no two designs are the identical.
