LIT OBJECT · PETG & PLA · CUSTOM LED LAYOUT
Arc Reactor
Building a mechanism that carries light, not a replica.
Parts were split by the job they do: the pieces that carry light and take heat were printed in PETG, while the structural surfaces that hold the detail were printed in PLA. The copper coils were remodelled from scratch for dimensional accuracy and fit, and the LED placement and internal wiring were planned so no hotspot shows on the surface.
THE FINISHED PIECE
The light does not
come from outside.
The ring under the dial is fed by an LED system set inside the body. The copper coils break the light up and the metallic finish spreads it back across the surface.
NO HOTSPOTS
Even light.
One ring.
Drawing the copper
from scratch.
The coils in the base model were not accurate enough in size or fit, so all twelve were remodelled. The goal was not only the look, but a profile that seats correctly in mechanical terms.
Two materials,
one body.
The lit parts were printed in PETG: it handles heat better and lets light through. The structural and visible surfaces went to PLA, where what mattered was detail and a clean finish. That split was a decision made up front.
