About Castable Resin
production process
Castable resin and 3D printer seriously developed by a 65-year-old jewelry maker
If you are considering introducing a 3D printer or are having trouble with modeling or casting, please contact us.
Japanese jewelry manufacturer Ambrose has developed a jewelry castable resin for LCD/DLP printers, and we also recommend printers that can use it to its fullest potential.
from the developer

Recently, 3D printers have begun to penetrate the manufacturing site of jewelry. Technological innovation has improved the printing accuracy of low-cost LCD printers to a level that can be used in jewelry manufacturing operations.
I tried using castable resins from many manufacturers, but I couldn't find one that I was satisfied with, so I decided to develop it myself. Although manufacturing is outsourced to overseas manufacturers, all research and development, molding, and casting tests were conducted in Japan.
We have confidence in the molding accuracy and the texture of the casting. Even those who were not satisfied with castable resin until now will surely be satisfied. Gold and silver, which use gypsum-based and phosphate-based investment agents, are beautifully cast. Platinum is not yet on a stable rise, but it is almost there, so please look forward to the future.

Active Peeling System
▶ Resin tank add tilt motion to reduce peeling force while peeling, which helps big area peeling, and high viscosity resin peeling, meaning Prime 4K can applied for widely kind of resins, including hard to print resin like flexible resins.
Redefine 3D Print Precision
▶ Strictly control UV light engine uniformity and image distortion during manufacturing process.
▶ Built-in image optimization technology to correct image deviation caused by optical distortion and mechanism deviation, make the printing parts achieve advanced precision.
