Clear in the Bottle, White After Curing: Siraya Tech’s Cast Ultra Clear Pairs the Highest Wax-Like Content with Easier Printing

With 30% wax-like content, the most in the Cast series, Ultra Clear prints more easily than Cast True Blue. Its ivory-white finish after curing is the visible sign of that content.

Siraya Tech has introduced Cast Ultra Clear, a jewelry casting resin priced at $99 and now available at Amazon in the United States. It carries 30% wax-like content, the highest in the Cast series, yet it is easier to print than Cast True Blue. For jewelers casting bracelets, large pendants, and thick ring bands, that means patterns that are simpler to produce and built for the burnout demands of substantial pieces.

More Wax-Like Content, Easier Printing

Jewelers who cast heavy pieces know the usual trade-off. More wax-like content helps substantial patterns through burnout, but it has typically made a resin more demanding to print.

Ultra Clear was developed so studios don’t have to choose. It delivers the highest wax-like content in the Cast series while printing more easily than True Blue, and it still captures fine textures, contours, and engraving.

Clear in the Bottle, White After Curing

Ultra Clear is transparent as a liquid. After washing and post-curing, printed patterns turn a matte ivory-white with a look and feel close to traditional carving wax. The name reflects both states: “Ultra” for the highest wax-like content in the series, “Clear” for the resin in the bottle.

The color change comes from the material itself. The wax-like component and the cured resin bend light differently, so light scatters where they meet, the same reason milk looks white. The white finish is a visible sign of the wax-like content inside every pattern.

The finish is practical, too. Prongs, filigree, textures, and engraving are easier to inspect before investing. Patterns photograph well for client reviews, and jewelers used to carving wax get a familiar look and feel.

Built for Substantial Pieces

Ultra Clear is aimed at designs where heavy sections and fine details share one piece, such as a wide ring band with engraving or a large pendant with filigree and slender prongs. Higher wax-like content supports the burnout of thick sections, while easier printing makes those patterns simpler to produce.

Where Ultra Clear Fits in the Cast Series

Ultra Clear joins Purple, Royal Blue, and True Blue, giving the Cast series four levels of wax-like content from 16% to 30%.

Material Wax-like content Key characteristics
Cast Purple 16% Harder patterns and straightforward printing; an accessible starting point in the series
Cast Royal Blue 20% A middle step in wax-like content between Purple and True Blue
Cast True Blue 24% A well-established choice for thicker patterns, including bracelets and large pendants
Cast Ultra Clear 30% The most wax-like content in the series, easier to print than True Blue, and ivory-white after curing

Studios with an established True Blue workflow can keep it. Ultra Clear adds a step up in wax-like content for designs that call for it.

Print Settings and Casting Workflow

Ultra Clear follows the Cast series’ burnout workflow and works with common jewelry investment materials, so printed patterns move straight into familiar investing and burnout steps.

Siraya Tech provides official print settings for printers from Elegoo, Anycubic, Phrozen, UniFormation, and Creality as a starting point for testing. Studios can then fine-tune for their own pattern geometry, investment material, and burnout schedule.

Pricing and Availability

Cast Ultra Clear is priced at $99 and is available now at Amazon in the United States. Additional regional Amazon marketplaces and the Siraya Tech website will follow. Other Cast series resins are available through Amazon and the Siraya Tech website.
