Adom Chip Laser

Laser-etch a component's MPN into its CAD at the STEP layer — so the downloadable STEP, a Fusion 360 import, and the derived 3D model all carry the part number on the die. Not a viewer-only texture: it's real geometry in the STEP.

Why STEP-layer: Fusion imports a library via the STEP, not a GLB. And a laser mark on black epoxy is a color change, not a groove — so the mark is a shallow recess filled with a light-grey laser_etch inlay body, which reads on every surface (a bare recess is invisible in a flat-shaded render).

Call it (HTTP service)

Live at https://laserchip-6dn1tl7vjz5u.adom.cloud — POST a STEP, get an etched STEP:

curl -X POST "https://laserchip-6dn1tl7vjz5u.adom.cloud/etch?mpn=STM32F103C8T6" \
     --data-binary @chip.step -o etched.step

• mpn (required) — the part number to etch.
• frac (default 0.55) — mark width as a fraction of the die; smaller = subtler.
• Response is application/step; the X-Etch-Fontsize-Mm header reports the size.
• GET /health → {"ok":true,"version":"…"}.

No cadquery needed on your end — any Adom app can call the service.

CLI

adom-chip-laser etch  --in chip.step --mpn STM32F103C8T6 --out etched.step
adom-chip-laser board --in chip.step --mpn STM32F103C8T6 --name stm32f103c8t6 \
      --out-dir OUT --kicad-mod fp.kicad_mod

• etch — the core: chip STEP + MPN → etched STEP.
• board — full 3D deliverables: etched chip STEP + chip GLB (real materials + etch) + animated board GLB (chip on FR4/copper/solder/silk, toggleable laser_etch layer, pick-and-place animation).

What you get

• A downloadable STEP whose die carries the MPN — survives into Fusion.
• A 3D model with the mark and a toggleable laser_etch layer.
• Auto-fit, single subtle line, MPN-only. Proven across LQFP / QFN / TQFP / LGA.
