Precision Wax Casting Resin for DLP and LCD Printers

Clean Burnout, Low Ash, High Detail for Lost-Wax Jewelry & Dental Casting

Whether you are a jeweler casting custom gold rings or a dental technician fabricating gold crowns, inlays, and tooth covers, this wax-based casting resin gives you the same result: a 3D-printed pattern that burns out cleanly, leaves no ash in the mold, and transfers every detail of your digital design into the final metal piece.

This is not a generic castable resin with "wax" in the name — it is a wax-based photopolymer that actually contains wax as a core ingredient. That is what gives it the same burnout behavior jewelers and dental technicians have trusted for decades with hand-carved wax: clean combustion, minimal residue, low thermal expansion, and precise fit in the final casting. Print the pattern on your DLP or LCD printer, invest it the same way you would a hand-carved wax, burn it out on your existing schedule, and cast. The only step that changes is how the original pattern is made.

⚠️ Before You Print — Critical Handling Information for Wax-Based Resin

• ⚠️ This resin SOLIDIFIES below 18°C / 64°F. Because this resin contains real wax, it behaves like wax: it turns solid when cold. If your workspace, storage area, or the resin bottle is below 18°C, the resin will be too thick to print correctly — or will not flow at all. Before printing, confirm the resin is fully liquid and at room temperature (22–30°C / 72–86°F). If it has solidified during storage or shipping, warm it gently to room temperature before opening. Never microwave or apply direct heat.
• Shake for at least 2 minutes before every use, then wait 10 minutes. The wax component can stratify inside the bottle. Inadequate mixing leads to inconsistent curing across the build plate and unreliable burnout results. After shaking, let the resin rest for 10 minutes to allow air bubbles to escape before pouring into the vat.
• UV wavelength: Compatible with DLP and monochrome LCD printers in the 385–405 nm range. Confirm your printer's light source wavelength before ordering.
• PPE required during handling: Wear nitrile gloves and safety glasses when handling uncured resin. Work in a ventilated area. Wax content does not reduce the chemical hazard of the uncured photopolymer component.
• Filter before reuse. If a print fails and solid resin pieces end up in the vat, filter the resin through a standard resin filter before your next print. Cured particles in the vat damage the FEP film and LCD screen. Ensure the resin is above 20°C / 68°F before filtering so it flows cleanly through the mesh.
• Post-cure is required for clean burnout. An under-cured pattern does not burn out cleanly. Always fully UV-post-cure your printed patterns before investing — this is what guarantees ash-free burnout in the kiln.

How Does Wax Casting Resin Actually Work? (The Simple Version)

Imagine you want to make a silver ring with an intricate design. Here is what happens with this resin:

1. You design the ring digitally in CAD software — every detail, every curve, every engraving — exactly as you want it in metal.
2. You print it with this resin on your DLP or LCD printer. The result is a solid, ultra-detailed plastic pattern that looks exactly like the final ring — except it is made of wax-based resin, not metal.
3. You invest it — you place the pattern inside a metal flask, pour liquid investment plaster around it, and let it harden into a solid block. The pattern is now perfectly encased in mold material.
4. You burn it out. The flask goes into a kiln. The wax-based resin heats up, burns away completely, and leaves behind a perfect empty cavity in the exact shape of your ring — with every detail preserved. This is the critical step where "clean burnout" and "low ash" matter: any residue left in the cavity becomes a defect in your final casting.
5. You cast. Molten silver (or gold, or bronze) is injected into the cavity. It fills every groove and detail. Once cooled, you break away the investment, and your metal ring emerges with all the precision of your original digital design.

Why This Resin Produces Better Castings

• Clean, ash-free burnout: The wax-based formulation burns out like traditional jeweler's wax — fully and cleanly — leaving no carbon residue or ash in the mold cavity. Residue in the cavity creates porosity, rough surfaces, and inclusions in the final metal piece. Clean burnout means clean castings.
• Low thermal expansion factor: When heated during burnout, the wax component melts and shrinks away from the mold walls — instead of expanding into them. This protects fragile investment molds from cracking and preserves dimensional accuracy through the entire thermal cycle.
• Exceptional surface detail: The resin captures fine positive and negative engravings, milgrain edges, filigree work, and organic geometry with the resolution of your printer — which transfers directly to the surface quality of the final metal casting.
• Low shrinkage during printing and curing: The printed pattern dimensions stay close to the original CAD file, which means the final casting matches your designed sizes without requiring significant compensation factors in your design software.
• Compatible with all investment types: Works with standard phosphate-bonded investments used in jewelry casting — Plasticast, Optima, SRS, and similar products. No special investment required; use your existing casting materials and workflow.
• Smooth surface finish: Wax-based resins produce smoother surfaces than standard castable resins, which reduces post-casting polishing time and preserves fine surface textures in the final metal piece.

Dental Casting Applications

This resin works for dental casting using exactly the same lost-wax process as jewelry. The dental technician scans the patient's prepared tooth, designs the restoration in CAD, prints the pattern in this resin, invests it, burns it out in the kiln, and casts in the chosen metal alloy. The resin burns away completely — what ends up in the patient's mouth is only the metal, not the resin. This means the biocompatibility requirement applies to the metal alloy used, not to the resin itself.

• Gold crowns: Full-coverage restorations that cap a prepared tooth. The wax pattern is printed to the exact anatomy of the patient's preparation — the precision of 3D printing means better marginal fit and less chairside adjustment compared to hand-carved wax.
• Inlays and onlays: Partial gold restorations that fit inside or over a tooth. Because these fit into a prepared cavity, dimensional accuracy of the printed pattern is critical — any deviation translates directly to gaps or tight spots in the final restoration.
• Decorative gold tooth covers (grillz): Custom-fit gold covers worn over the teeth for aesthetic purposes. The workflow is identical to a crown: impression or scan of the patient's teeth → CAD design → print in wax resin → invest → burnout → cast in gold → polish and fit. The precision of 3D printing produces a closer fit than traditional hand-fabricated grillz.
• Removable partial denture frameworks: Metal frameworks for partial dentures cast in cobalt-chrome or gold alloys.
• Custom implant abutments and bars in castable metal alloys.

⚠️ Important note for dental applications: The resin is a casting pattern — it is fully consumed during burnout and never contacts the patient. The biocompatibility and regulatory requirements apply to the metal alloy used for casting, not to this resin. Always use dental-grade certified alloys for any restoration intended for intraoral use.

Technical Specifications

Recommended Print Settings

Wax-based resins behave differently from standard resins on the same printer. Because the wax softens at low temperatures, the printed pattern is more delicate than a standard resin print — handle with extra care before and after post-curing. Keep lift speeds slow to prevent delamination on thin, intricate jewelry features.

Investment Casting Workflow — From Print to Metal

1. Remove from build plate with care — wax-based resin patterns are more delicate than standard resin prints. Support the piece from below during removal.
2. Remove supports carefully using fine flush cutters or a sharp scalpel. Work under magnification for fine jewelry pieces. Sand support witness marks before investing if surface quality is critical.
3. Wash gently in IPA. Short, gentle immersion — 2 to 3 minutes maximum. Do not use an aggressive ultrasonic cycle on thin, delicate patterns. Pat dry; do not blow-dry with strong air pressure, which can stress thin walls.
4. Post-cure fully under UV. Full UV post-curing is mandatory before investing — an under-cured pattern does not complete combustion cleanly. Cure completely on all sides using a rotating UV curing station.
5. Sprue and invest using your standard phosphate-bonded investment at room temperature per the manufacturer's water/powder ratio. Allow the investment to set fully before beginning the burnout cycle. A minimum 2-hour bench set time is recommended before the flask enters the kiln.
6. Burnout cycle. Use a controlled ramp:
   • Stage 1: Ramp slowly to 150°C (302°F) — hold until wax component has fully melted and drained
   • Stage 2: Ramp to 700°C (1292°F) — hold until complete combustion of remaining resin (typically 2–3 hours depending on flask size)
   • ⚠️ Do not rush the ramp — rapid temperature increases crack the investment before the resin has fully evacuated
7. Cast at the appropriate metal temperature for your alloy. Use vacuum or centrifugal casting for optimal cavity fill. Quench, pickle, and finish as normal.

Who Is This Resin For?

This wax casting resin is the right choice if:

• You are a jeweler, goldsmith, or metal caster already using lost-wax investment casting and want to replace hand-carved or injected wax patterns with 3D-printed ones — without changing your investment, kiln, or casting setup.
• You are a dental technician fabricating gold crowns, inlays, onlays, or removable partial denture frameworks — the workflow is identical to jewelry casting. You scan the patient's tooth, design the restoration digitally, print the wax pattern, invest, burn out, and cast in your chosen dental-grade alloy. The resin is fully consumed in the kiln — only the metal contacts the patient.
• You make custom gold tooth covers or grillz — the process is exactly the same as a gold crown: scan or impression of the patient's teeth → CAD design → print in wax resin → invest → burnout → cast in gold → polish and fit. 3D printing gives you a precision fit that is impossible to achieve consistently by hand.
• You need a resin that burns out cleanly at standard wax burnout temperatures and leaves no ash residue that would contaminate the mold cavity and create casting defects.
• You produce highly detailed pieces — fine engravings, filigree, milgrain edges, organic forms — where surface quality in the printed pattern translates directly to surface quality in the final metal casting.
• You own a 385–405 nm DLP or monochrome LCD printer and a UV curing station, and already have an investment casting setup with kiln and casting equipment.

This resin is NOT the right choice if you only need a standard castable resin without the wax component, or if you are looking for a resin for display models, prototypes, or dental lab models that are not being cast into metal. For standard castable resins, see our Castable Resin collection.
