Why Choose Castable Wax Resin?
Castable Wax Resin is a specialized photopolymer containing wax, designed for producing metal parts via the traditional “lost wax” investment casting process. Produced with Resin 3D Printing (SLA / DLP), these patterns burn out completely with 0% ash content when placed in a investment mold and fired. This creates a perfect cavity for casting everything from intricate jewelry settings to precision industrial components. It eliminates the need for hand-carved wax or expensive metal molds, bringing digital precision directly to the foundry.
Advantages
Clean Burnout (Zero Ash): Leaves no carbon or ash residue after burnout, preventing porosity or surface defects on the cast metal part.
High Detail Resolution: Capable of printing micron-level details, ensuring crisp settings and patterns for jewelry and dental applications.
Standard Process Compatibility: Works with standard wax burnout schedules, requiring no major changes to existing foundry workflows.
Rapid Production: Turns CAD designs into castable wax patterns in hours, skipping the tooling stage for Low Volume Production.
Limitations
Fragility: Softer and more brittle than standard prototyping resins; requires careful handling when assembling on the casting tree.
End-Use: Strictly for creating casting molds; not suitable as a functional end-use part.
Shelf Life: Sensitive to light and humidity; recommended to be cast shortly after printing.

Castable Resin FAQ
Which metals can be cast with this resin?
Patterns printed with Castable Wax Resin can be used to cast precious metals like Gold, Silver, Bronze, and Brass, as well as industrial alloys like Stainless Steel and Titanium.
Does it leave residue after burnout?
No. The formulation is designed to turn completely into gas at high temperatures (typically 750°C – 900°C). With 0.00% ash content, it ensures a flawless metal surface free of inclusions.
Is it suitable for jewelry?
Absolutely. It is the industry standard for rings with stone settings, pendants, and filigree designs requiring high precision. Besides jewelry, it is also used in Medical and Healthcare Technologies for casting dental crowns and bridges.
How is it different from standard resin?
Standard resins do not burn out cleanly; they swell and carbonize, ruining the investment mold. Castable resin behaves like wax, melting and evaporating cleanly. Therefore, it is the only choice for direct investment casting.
Does it require a special burnout schedule?
Most Castable Resins are compatible with standard wax burnout cycles. However, for optimal results, following the manufacturer’s recommended temperature ramps is advised. You can find general guidelines in Investment Casting Burnout Cycles – Delmer Group.
Do I need to sand the model?
Generally, no. SLA technology already provides a smooth surface. Excessive sanding might damage fine details or alter casting tolerances. Simply removing support marks is usually sufficient.
