Art Casting and Digital Sculpture — From CAD to Monumental Bronze
When artists conceive monumental visions, traditional lost-wax handcraft becomes the bottleneck. 3DPTEK SLS wax mold 3D printing replaces weeks of manual wax work with digital precision, enabling complex surface textures, thin-walled structures down to 5 mm, and sculptures up to 9 meters tall. Two landmark projects: Peaceful Elephant and Deep Sighs of the Pacific.
What We Cast for Artists and Sculptors
Art casting is fundamentally different from industrial casting: every piece is one-of-a-kind, surface texture is paramount, and the artist vision must survive the journey from digital model to monumental metal. Our SLS wax mold technology makes that possible at any scale.
Monumental Sculpture
Up to 9 meters tall, 9 tonnes. Single-piece or segmented assembly casting for public art and memorials.
Architectural Relief
Wall panels, facade elements, and ornamental building features. Complex bas-relief detail preserved.
Heritage Restoration
Replicas of damaged or missing sculpture sections. 3D scan to wax mold to exact metal reproduction.
Custom Installations
One-off artistic commissions, gallery pieces, and corporate art. Any metal, any finish, any complexity.
Sculpture Casting Services We Provide
Every art project has unique requirements — size, material, surface detail, timeline. Here is the full range of sculpture casting we deliver, each with documented landmark projects.
Monumental Outdoor Sculpture Casting
Large-scale public sculptures, war memorials, national monuments, and iconic commercial installations. Our 9-meter Peaceful Elephant in 316L stainless steel (9 tonnes) demonstrates our capability at the extreme end of scale. We print SLS wax mold segments, assemble them into casting clusters, and pour in our foundries equipped for multi-tonne pours. Weather-resistant alloys: 316L stainless, silicon bronze, aluminum.
Bronze Portrait and Figurative Sculpture
Life-size and larger-than-life human figures, busts, and animal sculptures. Silicon bronze captures every nuance of the artist clay or digital model — from skin texture to fabric folds. Our SLS wax molds reproduce details that hand-carved wax cannot match: consistent wall thickness, zero mold seams on critical surfaces, and perfect symmetry.
Architectural Art and Relief Casting
Building facade panels, ornamental grilles, decorative reliefs, and entrance sculptures for hotels, cultural centers, and corporate headquarters. Our digital wax mold process maintains perfect registration across large relief panels, ensuring seamless assembly on-site. Materials: bronze, brass, aluminum, stainless steel.
Custom Art Installation Casting
One-off artistic commissions, gallery exhibition pieces, and corporate art collections. Artists work directly from their digital files (STL, OBJ, STEP) and receive a finished metal sculpture without weeks of manual wax carving. Ideal for complex geometries with undercuts, thin sections, and interlocking parts.
Heritage Restoration Casting
Replacement casting for damaged or missing sections of historic sculptures, statues, and architectural ornaments. 3D scan the surviving original, digitally reconstruct the missing portion, print the SLS wax mold, and cast a perfect replica. Same metal, same patina, seamless integration with the existing artwork.
From Digital Art to Finished Sculpture
Unlike traditional lost-wax casting which requires weeks of manual wax carving, our digital pipeline compresses the journey from artist vision to physical metal into a streamlined, repeatable process.
Digital Model
Artist provides CAD file (STL, OBJ, STEP). For existing sculptures, we 3D-scan and digitize. Model optimization for printability and casting flow.
SLS Wax Mold Printing
Laser-sintered wax patterns printed at 700×700×500mm per build. For monumental works, segments are printed and assembled into casting clusters.
Investment and Casting
Ceramic shell investment, wax burnout at 800°C, and metal pour. Silicon bronze at 1,150°C, 316L stainless at 1,550°C.
Finishing and Patina
Shell removal, metal chasing, weld assembly for segmented works, surface finishing, and chemical patina to artist specification.
Art Casting Case Studies
These landmark projects demonstrate 3DPTEK capability at the intersection of art, engineering, and additive manufacturing.
Peaceful Elephant — 9m Monumental Sculpture
A 9-meter-tall elephant sculpture weighing 9 tonnes — one of the largest SLS wax mold investment castings ever produced. The segmented approach required 3D-printed wax mold clusters assembled with sub-millimeter precision. The 316L stainless steel provides permanent outdoor weather resistance without protective coating.
Deep Sighs of the Pacific
A 1,445 kg silicon bronze sculpture featuring deeply organic, flowing surface textures. The artist digital model contained surface details that would have been impossible to reproduce by hand in wax. SLS wax mold printing captured every nuance — the finished bronze is indistinguishable from the digital render.
Metals for Art and Sculpture
Three alloy families for artistic expression, each with distinct aesthetic and performance characteristics.
Silicon Bronze
Warm golden-brown. Patinas to greens, browns, blacks. The classic sculpture metal. Pour at 1,150°C.
316L Stainless Steel
Bright silver-white. Zero corrosion, zero maintenance outdoors. Pour at 1,550°C. Ideal for monumental works.
Aluminum Alloy
Lightweight silver-gray. Anodizable in colors. Ideal for interior installations and suspended artworks.
Brass
Rich golden tone. Develops natural patina over time. Excellent for architectural ornaments and decorative elements.

Art Casting FAQ
Traditional lost-wax requires an artisan to hand-carve or hand-model a wax positive from the artist original — a process that takes weeks for large or complex works and introduces human interpretation between the artist vision and the final metal. SLS wax mold printing eliminates this step: the artist digital model goes directly to the printer, which laser-sinters the wax pattern with micron-level fidelity. The result: faster turnaround, perfect fidelity to the digital model, and the ability to produce geometries (thin walls, undercuts, complex textures) that hand-carved wax simply cannot achieve.
We have produced a 9-meter-tall, 9-tonne elephant sculpture in 316L stainless steel — among the largest SLS wax mold investment castings ever made. For sculptures exceeding single-piece mold capacity, we use segmented printing and casting: individual wax mold clusters are printed, the metal segments are cast separately, then welded and chased to create a seamless final assembly. Our LaserCore-6000 builds wax molds up to 1050 x 1050 x 650mm per piece.
STL, OBJ, STEP, and IGES are standard. For artists working from physical maquettes or existing sculptures, we can 3D-scan the original and produce a digital model for wax mold printing. We also accept ZBrush and Blender native files. Our engineering team will review your file for printability and casting feasibility, suggest any optimizations (wall thickness, draft angles, parting lines), and provide a detailed quotation within 24 hours.
Yes. We produce sample patina panels on the same alloy and surface finish as your sculpture, which you review and approve before we apply the final chemical patina. Silicon bronze can achieve a wide range of colors: golden, brown, green (verdigris), blue-green, dark brown, and black. Stainless steel can be brushed, mirror-polished, bead-blasted, or electroplated.
Typical timeline: 1 to 2 weeks for wax mold printing (depending on size and segmentation), 2 to 3 weeks for investment casting and shell removal, and 1 to 2 weeks for metal chasing, welding assembly (if segmented), surface finishing, and patina. Total: approximately 4 to 8 weeks from approved digital model to finished sculpture. Rush timelines are available for gallery exhibition deadlines.
