3D printing for Casting Patterns

3D printed casting patterns for investment casting, lost-wax, and jewelry.

Investment casting and lost-wax processes require sacrificial patterns with fine detail, smooth surfaces, and clean burnout characteristics. Our 3D printing service produces casting patterns in Castable Resin on SLA — eliminating the need for traditional wax injection tooling and enabling complex geometries that would be impossible to mold conventionally.

Challenges we solve

What casting patterns teams need from a 3D printing service

Eliminating wax injection tooling

Traditional casting patterns require wax injection molds — $2K–$15K per mold and 2–4 weeks lead time. 3D printed patterns eliminate the mold entirely. Upload your CAD file and receive casting-ready patterns in 2–3 business days. For one-off pieces and short runs, this saves thousands of dollars and weeks of time.

Capturing fine detail in cast surfaces

Jewelry filigree, dental margin lines, and industrial precision features require patterns with sub-50 μm resolution. Castable Resin on SLA prints at 25 μm layer height with 1 Ra μm surface roughness — detail that transfers directly to the cast metal surface with minimal finishing.

Clean burnout without casting defects

Residual ash from pattern burnout causes porosity and surface defects in the casting. Castable Resin is formulated for clean burnout at standard investment casting temperatures (700–730°C) with minimal residue. Follow our recommended burnout schedule for best results.

Complex geometries impossible to mold

Undercuts, internal channels, interlocking features, and organic shapes that cannot be produced with traditional wax injection molds are standard for 3D printed patterns. If your CAD model is watertight, we can print it — regardless of geometric complexity.

Materials

Materials for casting patterns

Castable Resin on SLA is purpose-built for investment casting — clean burnout at 700-730°C with minimal ash residue, 1 Ra μm surface finish for smooth cast surfaces, and 25 μm layer height for capturing fine detail like filigree, prong settings, and micro-textures. For larger casting patterns or master patterns that will be used to create silicone molds, Standard Resin provides excellent surface quality at lower cost. For functional cast-metal prototype validation before committing to the casting process, Tough 2K provides a durable stand-in for handling and fit-checking.

How it works

Your project, step by step

01

Upload pattern file

Upload your STL or STEP. Include sprue and gate geometry if you want patterns ready to mount on a tree, or we can print the pattern body only for your casting house to gate.

02

File review

We verify wall thickness, feature resolution, and orientation for optimal surface quality on visible cast surfaces.

03

Print

Patterns printed on SLA in Castable Resin at 25 μm layer height. Support placement is optimized to avoid marks on critical surfaces.

04

QA & clean

Patterns are post-cured, supports removed, and surfaces inspected. Dimensional verification on critical features.

05

Ship

Patterns shipped in protective packaging to prevent damage. Ready for investment, burnout, and casting on arrival.

FAQ

Frequently asked questions

What resin do you use for casting patterns?

Castable Resin on our SLA platform — formulated specifically for investment casting. Clean burnout at 700–730°C, 1 Ra μm surface finish, and 25 μm layer resolution.

Can you print patterns with sprues and gates attached?

Yes — include sprue and gate geometry in your CAD file and we print them as part of the pattern. Or we print the pattern body only for your casting house to gate and tree according to their process.

What metals can be cast from your patterns?

Our Castable Resin patterns are compatible with standard investment casting processes for gold, silver, platinum, bronze, brass, stainless steel, and other alloys. Consult your casting house for specific alloy compatibility with resin burnout.

How many patterns can I order?

One pattern or hundreds. No minimum order. For jewelry production runs, we can produce dozens of unique patterns in a single build.

Do you offer casting services?

No — we produce the patterns only. We can recommend casting houses in the NYC area if you need a referral.
