The brief
Create a branded hanging sign in the ArmMed Designs style: bold contrast, crisp lettering, and a premium look without paint. This was a first-time build from scratch, so the goal was to validate the full workflow — logo preparation, CAD, printing, and assembly.
What mattered
- A clean front face (no visible fasteners)
- Accurate colour match (red/white on black)
- “Floating” stacked layers that align perfectly
- A solid, durable base with a quality texture
Design and print approach
1) Textured black base (printed face-down)
The base is a rounded rectangle printed in black PLA at 100% infill for a solid feel. It was printed face-down on a carbon-texture build plate, so the visible front surface picked up the pattern automatically.
2) Embedded metal rings for a clean hanging mount
Instead of adding hooks after the fact, the mounting hardware is built into the print. Two upper rear standoffs were designed with holes for metal rings. During printing, the job was paused, the rings were inserted, and printing resumed — capturing them inside the part.
A ~40 cm steel chain was then attached to the rings.
3) Floating red background + floating white lettering
The design uses three physical layers:
- Black base (full sign)
- Red panel behind “ARMED” (appears to float above the base)
- White “ARMED” lettering (appears to float above the red panel)
To make assembly repeatable, each layer includes positioning features: shallow pockets on one side and matching tabs/standoffs on the other, with a tight clearance (a few millimetres). Parts were joined with a small amount of cyanoacrylate (super glue).
4) Logo workflow: JPEG → vector → Fusion 360
The logo started as a raster image. It was vectorised, imported into Fusion 360, and cleaned up so the typography would print reliably. Hidden rear supports were shaped to follow the lettering while staying visually discreet.
5) Print settings and minimal cleanup
The sign was printed at 0.16 mm layer height at around 220°C (PLA). Post-processing was intentionally light: sanding inside letter faces where needed and a quick flame pass to remove micro-hairs.
Result
A durable, high-contrast brand sign with a textured base and clean floating layers — a good template for future branded signage projects (different sizes, fonts, logos, colours, and background textures).
