Water-Washable Dental Model – Beige – Phrozen
Description
Water washable resin for dental models provides a high level of accuracy after curing with minimal shrinkage. Its water-washable formula makes it easy and safe to work with even in an office environment, providing convenience for patients and practitioners alike. With more than 90% variation with ±0.05mm tolerance, Water-Washable Dental Model Resin exhibits incredibly high accuracy when scanned and compared to the actual STL file, making it reliable for detailed diagnostic models.
Ideal for printing on:
。Models of crowns and bridges with movable moulds
。Analog models of implants
。Diagnostic models
Before we print the perfect object, it’s important to first understand the limitations of the material we’re working with and how it can be successfully printed under different conditions. With this in mind, Phrozen provides the following design suggestions to help you better understand the properties of each material and how best to use them to bring your wildest creation to life.

Suggestions for printing
Shake the resin well before pouring it into the vat.
Full plate printing
When printing prints in full plate, it is recommended to add 1-2 seconds of rest time.
Cleaning
After removing the printed object from the build stage, use an ultrasonic cleaner and clean water for 5 minutes to remove uncured resin from the surface. Make sure the object is thoroughly cleaned, then leave it in a dark place for up to 30 minutes or use an air gun to dry the printed object immediately.
Avoid scrubbing the printed object as this can cause excessive cleaning and affect precision tolerances.
After curing
Use Phrozen post-cure lamps (Cure V2, Cure Luna, Cure Mega) or other post-cure lamps of the same wavelength to cure printed objects. Cure for 30 minutes to achieve good mechanical properties and precision.
