From Body Scans to Sculpture: Working with the Human Form in Digital Fabrication
Figurative sculpture has always demanded a level of accuracy that’s genuinely difficult to achieve by hand. Capturing the specific proportions of a specific person — the exact set of their shoulders, the particular geometry of a face — requires either extraordinary skill, endless time, or both. Digital fabrication offers a third option: scan the subject, work from data, and let the fabrication tools deliver the accuracy. Body scanning for sculpture uses structured light or photogrammetric techniques to capture the three-dimensional geometry of the human form, producing data accurate enough to drive CNC machining, 3D printing at scale, and mold-making for cast work.
What body scanning for sculptural work actually looks like
The capture workflow depends on the scale and purpose of the work:
Portrait busts and head scans are typically done with structured light scanning — the subject sits still while a scanner captures their face and head from multiple angles. With good technique, the resulting mesh captures skin texture, fine hair geometry, and the subtle asymmetries that make a likeness read as a specific person rather than a generic type. Processing takes additional time: cleaning scan artifacts, filling areas that were occluded during capture (inside ears, under the chin, behind the neck), and preparing the mesh for downstream fabrication.
Full-figure scanning typically uses a turntable setup or multiple-scanner rig to capture the subject from all angles without requiring them to hold completely still for extended periods. Photogrammetry — using a large array of calibrated cameras to capture the subject simultaneously — is increasingly common for full-body work because it’s effectively instantaneous. The tradeoff is that photogrammetry tends to capture less fine surface detail than structured light; the right choice depends on how much surface texture needs to be preserved.
For large-scale public art, the body scan often serves as the reference for a scaled-up version rather than a life-size one. Scaling from a body scan is exact — the proportions and relationships in the data are preserved precisely at any scale, something that’s essentially impossible to guarantee in hand-scaled work.
From scan to physical sculpture: the fabrication options
Once the mesh is clean and prepared, the fabrication path branches based on the intended final material and scale.
CNC foam carving is the dominant approach for large-scale figurative work. A dense foam block is carved to the scan geometry by a multi-axis CNC machine, producing a form accurate to within a few millimeters at large scale. The foam can then be coated — hard coat for permanence, fiberglass for structural strength, or painted directly for painted surface finishes. This is how large public figures and monumental installations are typically produced.
3D printing works well for smaller-scale figurative work, artist editions, and maquettes. SLA printing gives excellent surface detail for portrait-scale work. For larger pieces, sectional printing with careful seam placement allows full-figure work at sizes up to life-scale, though post-processing and seam work is labor-intensive.
Mold-making and casting is the traditional finish for figurative work intended for permanence. A silicone mold taken from a printed or machined master allows the figure to be cast in resin, plaster, bronze-filled resin, or — through a foundry — true bronze. The bronze casting workflow is how scan data connects to the oldest tradition in sculpture: the physical surface of the scan becomes the pattern for lost-wax or sand casting.
Working with existing sculpture vs. working from the figure directly
Body scanning for figurative work doesn’t always mean scanning a live subject. Many of our projects in this space involve scanning an existing sculpture — a maquette, a life cast, or a studio model — as the starting point for scale production or reproduction. The scan workflow is the same; the source just happens to be plaster or clay rather than a person.
This distinction matters for artists working on public commissions: the artist can develop their work at a scale they can handle in the studio, finalize the surface treatment, and then hand off a scan of the studio piece to drive fabrication at monument scale. The creative work happens at the scale the artist controls; the technical scaling problem is solved digitally.
We’ve worked on projects like this with sculptors connected to New York Art Foundry and on figurative work for public art installations across the city.
