Description
RCZ557
temporary dental crown 3D Resin
Characteristics:
The RCZ-502 is temporary crown and bridge resins which have good weatherability and molding
stability. It is a non-skin irritation and non-skin allergy 3D printing photosensitive resin. It has the
characteristics of fast printing speed, high precision, and smooth surface of the finished product. The material
has ultra-high fracture resistance, bending resistance and high wear resistance. Its printed products have a
natural tooth look texture and the color is a translucent tooth color. It is ready to use after a simple surface
treatment and polishing. Suitable for mass-produced products such as temporary crowns, temporary bridges,
temporary teeth, invisible models, trial models for various dental and medical applications. Stable in oral
environment, odorless and tasteless.
Key Features:
Natural tooth appearance texture (A2 color)
High printing accuracy
High printing speed
High fracture and bending resistance
High mechanical strength
