3D-Printed Wax Patterns for Investment Casting Foundries

Industry Challenges

Foundry Pain Points We Solve

Traditional wood or wax tooling takes too long and costs too much to justify for small trial batches.
Complex-internal-cavity castings — valves, pump bodies — can't even be tooled as wax patterns conventionally.
Wax-pattern accuracy directly drives casting yield, yet conventional wax injection has uncontrollable shrinkage and warping.
Ash residue left after wax burnout degrades the cast surface finish.
Cutting steel tooling for a small order doesn't pay off, yet clients still demand a short lead time.

FAQ

Frequently Asked Questions

Can 3D-printed resin patterns really replace traditional wax patterns?

Yes, with low-ash-residue material the pattern can go straight into the lost-wax process — validated in automotive, aerospace and jewelry casting. For high-volume production, conventional wax injection may still win on per-unit cost.

What's the ash/residue level after burnout?

Our low-ash-residue resin leaves significantly less burnout residue than general-purpose print resin — request the material test report via the inquiry form for exact figures.

What dimensional accuracy can casting-grade patterns achieve?

Our SLA/DLP machines hold accuracy to roughly ±0.1mm; final casting accuracy also depends on burnout and pouring process — send a drawing for a first-article evaluation.

What's the fastest turnaround from CAD file to a castable pattern?

Standard-size patterns can ship in 48–72 hours; complex-internal-cavity parts take slightly longer depending on post-processing needs.
