Material Profile: AnyCast Resin for SLA / LCD 3D
Phrozen SLA / LCD Resin Technical Report Series
Compiled from Phrozen official datasheets, SDS documents, and third-party technical reviews
Abstract—Phrozen AnyCast (Green) is a versatile castable photopolymer designed for direct lost-wax investment casting of metal jewelry. The formulation is optimised for clean burnout (low ash residue) across a wide range of investment plaster types and casting machines, making it a practical 'one resin, many casters' solution for jewelry studios.
Index Terms—additive manufacturing, SLA, LCD, photopolymer, castable, jewelry, lost-wax casting, metal casting.

II. COMPOSITION AND PHOTOPOLYMER CHEMISTRY
A. General Resin Family
Generic photo-polymerisation: monomers (multi-functional acrylates / urethane-acrylates) + photoinitiator (e.g., TPO / BAPO) + 405 nm UV → crosslinked thermoset network. Exact formulation is proprietary. Wax-content additives engineered for clean burnout in lost-wax casting.

III. MECHANICAL PROPERTIES
Castable resins are not engineered for end-use mechanical service; the cured pattern is destroyed during burnout. Properties below are typical for the cured pattern strength.

Wash medium |
Isopropyl alcohol (IPA) or 95% ethanol |
30–60 s wash; do not over-soak |
|
Post-cure |
405 nm UV box, 15–30 min only (avoid over-cure to preserve burnout cleanness) depending on size |
Phrozen Cure Mega S or equivalent |
V. GLASS TRANSITION TEMPERATURE (TG)
Reported / typical Tg: Not directly applicable (casting pattern; not for end-use service).
Pattern is consumed in casting investment burnout cycle (peak ~720–760 °C).
VI. HEAT DEFLECTION TEMPERATURE (HDT)
HDT defines the temperature at which a 1.27 mm-thick standardised bar deflects 0.25 mm under the specified flexural load. Two test loads are reported per ASTM D648 / ISO 75.

VII. DISTINGUISHING CHARACTERISTICS AND STANDARDS
A. Wide caster compatibility — 'AnyCast' philosophy
Compatible with most investment plaster brands (R&R, Plasticast, Goldcast, etc.) and casting cycles. Reduces the need to change resin when switching investment supplier or casting house.
B. Clean burnout (low ash residue)
Wax-modified formulation burns out cleanly in standard investment heating cycles, leaving minimal residue and producing high-quality castings.
C. Universal jewelry casting suitability
Suitable for silver, gold, platinum, and most precious metal alloys. Pattern detail is preserved through investment due to dimensional stability of the cured photopolymer.
D. Cost-effective vs single-purpose castable resins
One resin replaces multiple specialist castable products in a typical studio workflow.
VIII. REPRESENTATIVE APPLICATIONS
AnyCast Resin is typically deployed in the following applications:
1) Jewelry casting masters: Rings, pendants, earrings, bracelets — direct burnout in investment plaster.
2) Custom-fit dental crowns and inlays: When designed for direct casting in noble or non-noble alloys.
3) Small precision metal parts: Custom hardware, fasteners, decorative elements for short-run casting.
4) Concept design verification: Cast a pattern in cheap metal to verify form before committing to precious metal.
5) Educational metal-casting demos: Studio / school demonstrations of digital-to-metal workflow.
