3D Printing.

Digital files become physical objects, one slice at a time.

A 3D printer doesn't carve a shape — it builds one. The model is sliced into a stack of layers as thin as a sheet of paper. The machine lays down (or cures, or sinters) one layer at a time, and the part grows upward as the bed drops. What was a polygon mesh in the morning is a holdable object by lunch.

01 · The thirty-second version

A pancake stack made of plastic.

Take any 3D model. A piece of software called a slicer chops it into hundreds of horizontal cross-sections — each as thin as 0.1 mm. For each slice, it generates a path that the printer's nozzle (or laser, or UV light) needs to follow to draw that layer in the correct material. That whole instruction list is exported as G-code.

The printer reads the G-code line by line. FDM printers melt plastic filament and squirt it through a heated nozzle, building each layer in molten ribbons that fuse as they cool. SLA printers cure liquid resin layer by layer with UV light, producing impossibly smooth surfaces. SLS printers fuse nylon powder with a laser, leaving the unfused powder around the part as built-in support.

Different processes give wildly different parts. FDM is fast, cheap, and rough. SLA is slow, expensive, and glass-smooth. SLS is the strongest, supports complex internal geometry, and produces functional parts that can be drilled, threaded, and used. We pick the process to match what the prop has to do once it's in the room.

02 · The workflow

From CAD to part.

Five stages, each with their own pitfalls. A failed print teaches you which stage was the weak link.

01
Model
Design in CAD (Fusion, SolidWorks) or sculpt (Blender, ZBrush). Export STL or 3MF mesh.
02
Slice
Slicer chops mesh into layers, generates infill, supports, and tool paths. Outputs G-code.
03
Send
G-code transferred to printer (USB, SD, network). Printer pre-heats, homes axes, primes nozzle.
04
Print
Layer by layer, nozzle follows path. Bed drops one layer height. Repeat for hours.
05
Finish
Remove supports, sand, clean, paint. SLA needs UV post-cure. SLS needs powder removal.
03 · The toolkit

Processes, materials, software.

Different parts demand different tools. We keep multiple printers in the lab so we can pick per project, not per default.

Process · FDM
Filament
Cheap, fast, large parts. Visible layer lines but very forgiving. The workhorse.
PLA · PETG · ABS · TPU

Resin
UV-cured liquid. 25 µm layers. Glass-smooth surfaces. Brittle and odorous.
Standard · Tough · Clear
Process · SLS
Powder + Laser
Nylon parts that survive real-world use. Complex geometry, no support needed.

Where we've shipped printed parts.

Prop · FDM
Brand-shaped controllers
Capacitive touch controllers in custom enclosures shaped like the client's product. PETG body, copper-tape contacts, ESP32 inside. Three iterations from sketch to working prop in a single afternoon.

Mount · SLA
Projection rig brackets
Glass-smooth mounting hardware for sensor + camera arrays in client-facing installs. SLA gives a finish that looks designed, not workshop. Hidden in the rigging once installed.
Tough resinForm 3UV cure
Functional · SLS
Sensor enclosures
Nylon enclosures that handle being touched, dropped, and rolled around by exhibit visitors for weeks. SLS produces parts that survive what FDM wouldn't. Outsourced print, in-house assembly.
PA12HP MJFheat-set inserts
Prototype · FDM
Iteration sprints
When a prop has to feel right in hand, two-day FDM cycles beat a three-week injection mold. We sketch, print, hold, revise — sometimes three iterations a day. Finalize the geometry, then commit to the production process.

Tell us what it has to do. We'll pick the process.

Prototype, prop, enclosure, structural mount — different jobs, different processes. We've got FDM in-house and SLS/MJF on demand. We'll quote material + process + timeline within a business day.
