LaserCore-5300: The SLS Workhorse for Sand Molds & Wax Patterns
One platform. Two materials. Proven across 14+ units in our own smart manufacturing centers. The LaserCore-5300 delivers 80–300 cm³/h throughput with ±0.1 mm accuracy — so foundries can eliminate traditional pattern-making and ship castings faster.
What If You Could Eliminate Pattern-Making Completely?
Traditional sand casting relies on wooden or metal patterns that take weeks to produce, limit design freedom, and add significant cost. The LaserCore-5300 prints sand molds and wax patterns directly from your CAD data — no patterns, no tooling, no waiting.
Weeks-Long Pattern Lead Times
Traditional pattern-making takes 2–8 weeks. The LaserCore-5300 goes from CAD to mold in hours. That's your competitive edge in every bid.
High Tooling Costs for Low Volumes
Pattern tooling for complex castings can cost $5,000–$50,000+. With the 5300, there's no tooling. Print exactly the quantity you need — whether it's 1 or 1,000.
Design Constraints of Traditional Patterns
Undercuts, complex internal passages, thin walls — features that require multi-piece patterns. The 5300 prints complex geometries as easily as simple ones.
What the LaserCore-5300 Delivers
A production-grade SLS system engineered for foundries that need reliability, throughput, and material flexibility.
700 × 700 × 500 mm Build Volume
Large enough for most medium-to-large casting patterns. Print multiple small parts in one job or single large components up to 700 mm in any dimension.
80–300 cm³/h Throughput
Production-level build speed in its class. Complete a full-height build in a single shift. The RF CO₂ laser (55W / 120W options) ensures consistent sintering at speed.
±0.1 mm Dimensional Accuracy
Tight tolerances that meet foundry requirements. Sand molds come out dimensionally stable; wax patterns need minimal finishing before investment.
Dual-Material: Sand + Wax on One Machine
Switch between coated sand and PSB wax powder. Run sand molds during the day, wax patterns overnight. One machine, two production capabilities.
Proven Reliability — 14+ Units Running Daily
We don't just sell this machine. We run 14+ LaserCore-5300 units in our own manufacturing centers. Every improvement from our production floor feeds back into the product.
Compact Footprint: 1,960 × 1,460 × 2,690 mm
Fits in standard industrial spaces. No special foundation required. Power: 380VAC/50Hz/18KW three-phase. Standard factory utilities.
Sand Molds & Wax Patterns — One Machine, Twice the Value
Most SLS systems lock you into one material. The LaserCore-5300 gives you both — switch in under an hour. This means one capital investment covers two critical foundry workflows.
Sand Mold Printing
- Coated silica sand / ceramic sand — furan or phenolic resin binder systems
- Layer thickness: 0.08–0.35 mm, adjustable for surface finish vs. speed
- Direct mold-and-core printing — no pattern required
- Ideal for: pump housings, impellers, engine blocks, manifolds, large valve bodies
- Typical tensile strength: 1.5–2.5 MPa (comparable to traditional no-bake sand)
Wax Pattern Printing (Investment Casting)
- PSB (polystyrene-based) wax powder — burns out cleanly with minimal ash
- Layer thickness: 0.08–0.30 mm for fine surface detail
- Direct pattern printing — skip the wax injection mold entirely
- Ideal for: turbine blades, impellers, automotive turbocharger components, medical implants
- Compatible with standard investment casting shell materials and processes

Why Foundries Choose 3DPTEK's LaserCore-5300
Not just specs — here's what makes the difference in daily production.
30+ Years of SLS Mastery
We built our first SLS system in 1994. The LaserCore-5300 is the result of three decades of continuous refinement — not a first-generation product from a startup.
We Run What We Sell
14+ LaserCore-5300 units operate in our own smart manufacturing centers. Every software update, every process improvement is battle-tested on our own production floor before it reaches you.
Global Brand Core Components
CO₂ laser, galvanometer scanner, motion control — sourced from leading global suppliers. Not the cheapest components. The most reliable ones. Because downtime costs more than components.
Price Advantage vs. Competitors
Comparable build volume and throughput at a significantly better price point than European and American alternatives. Lower acquisition cost, lower operating cost, and faster local support.
Application Engineering Included

LaserCore-5300 FAQ
The LaserCore-5300 offers a larger build volume (700 × 700 × 500 mm vs 500 × 500 × 500 mm) and higher throughput (up to 300 vs 200 cm³/h) with an RF CO₂ laser (55W or 120W). Choose the AFS-500 for entry-level SLS or tighter floor space; choose the LaserCore-5300 for production throughput and the larger build envelope that handles mid-size molds, cores, and patterns.
Yes. It prints coated sand (silica or ceramic) for sand casting molds and cores, and PSB wax powder for investment casting patterns. You switch materials between builds — the changeover takes about 30–60 minutes. Many customers run sand during the day shift and wax overnight. In our own facilities, 14 LaserCore-5300 units run sand and 5 run wax around the clock.
Most customers achieve full ROI within 12–18 months. Key savings come from: eliminating pattern tooling costs ($5,000–$50,000+ per pattern set), reducing lead time from weeks to days (winning more orders), and reducing scrap through better mold consistency. We can prepare a customized ROI analysis based on your specific casting portfolio.
On-site installation, commissioning, and operator training (3–5 days). Remote diagnostics, process parameter optimization support, and preventive maintenance guidance included. With 14 LaserCore-5300 units running sand molds and 5 running wax patterns in our own smart manufacturing centers, our support team has deep hands-on experience with this platform — they're not reading from a manual, they're sharing production experience.
Absolutely. Visit one of our smart manufacturing centers in China to see multiple LaserCore-5300 units in production. Inspect print quality, talk to operators, and understand the full workflow from CAD to casting. We encourage site visits — seeing is believing. Contact us to schedule.
