Automotive & Motorcycle Casting — From CAD to Cast Part in Days
3D printed sand molds and SLS wax patterns eliminate tooling for automotive castings. Engine blocks, cylinder heads, transmission housings, structural frames — prototype in 3 days, serial production in weeks. Aluminum, cast iron, and magnesium alloys.
Why Automotive Manufacturers Choose 3DPTEK for Castings
Traditional sand casting requires wooden or metal patterns that take weeks to produce and thousands of dollars in tooling. 3DPTEK replaces patterns with digital files — print the mold directly and pour metal the same day.
Zero Tooling, Maximum Speed
No pattern shop, no CNC pattern machining, no storage racks. Upload your CAD file at 9 AM, and we can have a casting-ready sand mold printed by end of day. For serial production, digital molds eliminate pattern wear and maintenance entirely.
Complex Geometries Without Compromise
Internal cooling passages, thin-walled sections, organic shapes, undercuts — geometries that would require multi-piece patterns or are simply impossible with traditional methods become routine with 3D printed sand molds.
Prototype to Production on One Platform
The same 3D printing technology that delivers your first prototype casting in days scales directly to serial production. No process change, no tooling transition, no requalification. When your design is approved, production starts immediately.
Typical Automotive & Motorcycle Casting Parts
From engine components to structural frames, 3DPTEK casts the parts that automotive and motorcycle manufacturers depend on.
Powertrain
Engine Blocks & Cylinder Heads
Aluminum and cast iron engine blocks with integrated water jacket cores printed directly into the sand mold. Cylinder heads with complex port geometries that maximize flow. Single-piece or multi-cylinder configurations.
Drivetrain
Transmission Cases & Housings
Thin-walled aluminum transmission cases, bell housings, and gearbox covers. Internal ribbing and mounting bosses printed in a single mold.
Chassis
Structural Frames & Subframes
Large aluminum and iron structural components for NEV skateboard platforms, motorcycle frames, and suspension mounting points.
Brake Calipers & Masters
High-integrity aluminum brake calipers, master cylinders, and ABS housings with internal fluid passageways cast in place.
Turbocharger Housings
Heat-resistant cast iron and stainless steel turbo housings with spiral volute geometries printed directly from sand.
Casting Technologies for Automotive Parts
Different parts demand different casting approaches. 3DPTEK offers the full spectrum.
3DP Sand Mold Casting (Binder Jetting)
Ideal for large structural parts, engine blocks, and low-to-mid volume production. Print the entire sand mold package in one piece. Build volumes up to 4,000 mm. Furan, phenolic, and inorganic binders available.
SLS Wax Pattern + Investment Casting
For high-precision, thin-walled parts like turbocharger housings and motorcycle components. SLS-printed wax patterns deliver investment-casting surface finish with 3D printing speed. No wax injection tooling required.
Gravity & Low-Pressure Casting
Production-scale aluminum casting for cylinder heads, intake manifolds, and structural frames. 3D printed sand molds integrate directly with existing gravity and low-pressure casting lines.
SLM Direct Metal Printing
For ultra-complex, low-volume metal parts that cannot be cast. Direct metal 3D printing of aluminum, stainless steel, and titanium for functional prototypes and end-use performance components.
From CAD to Production Casting in 4 Steps
One partner from design review to certified castings — no handoffs between pattern shops, foundries, and machine shops.

Frequently Asked Questions
3DPTEK supports 3DP sand mold casting (Binder Jetting) for large structural parts up to 4 meters, SLS wax pattern + investment casting for high-precision components, and gravity/low-pressure casting for serial production. We also offer SLM direct metal printing for ultra-complex, low-volume performance parts.
For prototype castings, 3DPTEK can go from CAD file to casting-ready sand mold in as little as 24 hours. Including casting, finishing, and inspection, typical prototype delivery ranges from 3-7 business days depending on part complexity, material, and post-processing requirements. This compares to 6-12 weeks for traditional pattern-based methods.
3DPTEK casts aluminum alloys (A356, AlSi10Mg, 319, etc.) for lightweight structural and powertrain components, gray iron and ductile iron for engine blocks, brake components, and heavy-duty parts, and magnesium alloys for ultra-lightweight applications. All castings undergo dimensional inspection and can include mechanical testing certification upon request.
Both. We operate 10 smart manufacturing centers with dozens of industrial 3D printers and casting lines. We produce 2,000+ units/month for several automotive customers. The same 3D printed sand mold process used for prototypes scales directly to serial production without tooling changes.
