Skip the pattern shop entirely. Send us your 3D model, and our 45+ industrial sand printers produce your molds and cores — with ±0.3mm accuracy, in 24-72 hours. We have been printing sand molds since 1994.
No patterns. No tooling. No minimum order. Just upload your CAD and tell us what you need.
STL, STEP, IGES, or native formats. Tell us your alloy, quantity, and timeline.
Our casting engineers check printability and provide DFM feedback within 24 hours — free.
Fixed-price quote with sand type, binder selection, and delivery timeline. No hidden fees.
Molds printed within 24-72 hours, QC inspected against your CAD, export-packed, and shipped.
Every order includes these guarantees. No exceptions.
Every mold is CMM-inspected against your CAD. If any dimension is out of tolerance, we re-print at no charge. Full inspection report included.
Undercuts, internal channels, thin walls, organic shapes — if you can model it, we can print it. No pattern-making constraints.
Each mold is cured, cleaned, and export-packed in reinforced crates. Ready to pour the moment it arrives at your foundry.
Material certs, inspection reports, and process parameters shipped with every order. Traceability from sand batch to final mold.
Every case below was printed on our own equipment and shipped to a foundry. These are real molds, real castings, real delivery times.
China's largest power motor shell casting. 3D printed sand mold replaced traditional multi-piece pattern assembly. One-piece mold with integrated cooling channel cores.
5 prototype cylinder heads delivered in 15 days from CAD approval — 40% faster than traditional pattern making. All 5 castings passed dimensional and X-ray inspection.
Large-format thin-wall integrated molding. 3D printed sand mold enabled one-piece forming of geometry impossible with traditional pattern tooling. Zero draft angle required.
You do not need to decide. Send us your CAD and our engineers select the optimal process based on size, geometry, and your casting requirements.
Inkjet heads deposit our SS06 binder onto silica sand, ceramic sand, or ceramsite. Build volumes up to 4,000mm for the largest industrial molds. Fast. Economical. 25+ machines running 24/7.
CO2 laser sinters coated sand for superior strength and precision. Ideal for complex cores, thin-walled geometries, and high-pressure casting applications. 20+ machines running 24/7.
7 sand types available. Our SS06 binder delivers high strength, low gas evolution, fast curing, and low cost per mold. Or bring your own foundry sand — we optimize parameters to match.
SS06 Binder System — resin-based, proven across 500+ installations. High strength and hardness. Low gas evolution for clean castings. Fast curing speed for quick turnaround. High forming efficiency. Low cost per mold.
Sand Options: Silica sand, ceramic sand, ceramsite, coated sand, chromite sand, zircon sand, water-soluble mold material.
Already have a qualified foundry sand supply chain? Good. We test your sand composition, grain size distribution, and thermal properties — then optimize our binder parameters to match. No forced material purchases. No vendor lock-in. Your process, your sand, our printing expertise.
We design and manufacture every printer in our fleet. When you order molds from us, they run on the same machines we sell to foundries worldwide — refined over 30 years of continuous production.
Build volume up to 4000×2000×1000mm. Inkjet binder jetting at 200–400 L/h print speed. The workhorse of our fleet — delivering large-format sand molds and cores with 600 DPI resolution for heavy industry applications.

Build volume up to 1050×1050×600mm. CO2 laser with tensile strength 4.5–6.5 MPa. Dual-mode: prints both sand molds and wax patterns on one platform. Ideal for complex thin-wall cores and high-strength molds.
View SLS Printers →We eat our own dog food. The same printers we sell are the ones we use daily for commercial production. Every improvement from our service operation feeds directly back into our equipment design. When you order molds from us, you benefit from 30 years of iterative refinement that no print-only service bureau can match.
Most molds ship within 24-72 hours of CAD approval. 5-piece batches are typically delivered in 15 days including casting validation. Rush service is available for urgent projects.
3DP Binder Jetting: ±0.3mm dimensional accuracy, surface finish <Ra 25. SLS Sand Cores: ±0.1mm (≤100mm), ±0.1% (>100mm), tensile strength 4.5-6.5 MPa. Every mold is CMM-inspected against your CAD before shipping.
Yes. Send us a sample of your sand. We test its composition, grain size distribution, and thermal properties, then optimize binder parameters to match. Alternatively, we provide silica sand, ceramic sand, ceramsite, coated sand, and more with our SS06 binder.
Every mold is CMM-inspected against your CAD file before packaging. If any dimension is out of tolerance, we re-print at no charge. Material certifications and inspection reports are included with every shipment. We stand behind every mold we ship.
Yes, and it is free. Our casting engineers review your CAD for printability, optimal parting line, gating placement, and any geometry that could cause casting defects. You get actionable feedback within 24 hours. This alone often saves customers more than the cost of the molds.
STL, STEP, IGES, or native CAD formats (SolidWorks, NX, CATIA, Creo). Include your casting alloy, quantity, and desired delivery date for the fastest quote turnaround.
