Wax 3D Printing Service
— Precision Wax Patterns for Investment Casting
Send us your CAD file. We print high-precision SLS wax patterns — ready for your foundry's shell-building and investment casting process. ±0.1mm accuracy, Ra<3.2 surface finish, up to 1,400mm build envelope. From the company that designs, builds, and operates the printers — nobody knows the process better.
What Is SLS Wax 3D Printing — And Why It Changes Everything for Investment Casting
Traditional investment casting requires a metal tool (die) to inject wax patterns — a process that takes weeks and costs thousands before you pour a single gram of metal. SLS wax 3D printing eliminates the tool entirely. We print your wax patterns directly from CAD data, layer by layer, using selective laser sintering. No tool. No waiting. No minimum quantity.
👑 Why 3DPTEK for Wax Patterns? We Build the Printers.
This isn't a third-party print bureau running someone else's machine. 3DPTEK designs and manufactures the LaserCore series SLS wax printers in our own factory (Fanchang, Anhui). We formulate the wax materials. We write the AFSWin control software. When you order wax patterns from us, you're getting parts from the company that knows every parameter, every nuance, every optimization — because we engineered the entire system. And if you eventually want to bring wax printing in-house, we'll sell you the same printers and train your team.
How Our Wax Pattern Service Works — 3 Simple Steps
Upload Your CAD Model
Send us your 3D model in STL format. Our engineers review for printability, shell-building clearances, and shrinkage compensation — usually within 24 hours.
We SLS Print Your Wax Patterns
Your patterns are printed on our LaserCore SLS printers using PSB polymer wax or PSB polymer wax, depending on your casting alloy and surface requirements. Layer thickness: 0.08–0.35mm.
Quality Check & Ship to Your Foundry
Every pattern is dimensionally inspected. We package carefully and ship — your foundry builds the ceramic shell, dewaxes, pours metal, and you get precision castings.
Need the Castings Too?
We can handle the full chain: wax pattern → shell building → casting → machining → inspection. See our Rapid Casting service.
Traditional Wax Pattern Tooling vs. 3DPTEK SLS Wax Printing
The wax pattern bottleneck is eliminated. Design → print → cast. No tooling in between.
❌ Traditional Wax Injection Tooling
- Metal injection die: 4–8 weeks to design and machine
- Tooling cost: $5,000–$50,000+ depending on complexity
- Design changes require new tooling or expensive modifications
- Minimum order quantities to amortize tooling investment
- Tooling maintenance, storage, and lifecycle management costs
- Parting line constraints limit geometry complexity
- Lead time kills rapid prototyping and design iteration
✅ 3DPTEK SLS Wax 3D Printing
- First patterns delivered in 3–7 business days — zero tooling wait
- No tooling cost — pay per pattern, scale with demand
- Design iteration: change CAD, reprint — same day turnaround
- One pattern or ten thousand — no minimum, no maximum
- Zero tooling overhead — digital file storage only
- No parting lines — print any geometry the laser can reach
- Rapid prototyping → production transition on the same process

Frequently Asked Questions
PSB (Polymer Styrene Binder) wax is our proprietary SLS wax material formulated for investment casting patterns. It is compatible with most common casting alloys: aluminum, steel, stainless steel, cast iron, copper-based alloys. For high-purity alloys such as titanium and nickel-based superalloys, we recommend PSB low-ash wax (<0.02% ash content) — the same material used in our aerospace customer programs. Both materials print on the same LaserCore machines with no hardware changes.
Both. Option A: We print and ship wax patterns to your foundry — you handle shell building, casting, and finishing. Option B: Full-service precision casting through our Rapid Casting service — we print the wax, build the shell, pour the metal, machine, inspect, and ship finished castings. Many customers start with Option A and transition to Option B for production runs or complex alloys requiring our in-house casting expertise.
Standard lead time: 3–7 business days from CAD approval. Rush orders can ship in 48 hours. This compares to 4–8 weeks for traditional wax injection mold fabrication. For recurring production orders, we can hold capacity to guarantee your delivery schedule — effectively functioning as your virtual wax room, without the overhead.
For prototype and small-to-medium production runs (1–500 pieces), SLS wax printing is significantly more economical because you eliminate tooling costs entirely. At ~$200/KG in wax material plus printing time, a typical automotive component wax pattern costs a fraction of the $5,000–$50,000+ injection mold. For very high volumes (>10,000 pieces), traditional injection molding may become more cost-effective per unit — at which point we can help you transition (and sell you the SLS printers for prototyping).
That's exactly what many of our customers do — and we support it fully. Start with our wax printing service to validate the process with your castings. When you're ready, we sell the same LaserCore SLS wax printers we use in our own service bureau, plus materials, training, and ongoing process support. You get the benefit of our real-world production experience — not just an equipment manual.
