What's on the rack

Materials & stock

Solid outlines are on the rack today; dashed ones are special order (about four working days). Every note is the shop's honest word on how that stock lives here — salt air, UV, humidity.

Mild steel (CRS / A36)

Fiber · bends

Strong and cheap — and it rusts fast in salt air. Powder coat it or choose galvanised or stainless outdoors.

Galvanised steel (G90)

Fiber · bends

Zinc-coated: good for brackets and flashing outside. Cut edges are bare steel — touch them up.

Stainless 304

Fiber · bends

Clean and food-safe. Fine near the coast; within splash of the ocean, choose 316.

Stainless 316 (marine)

Fiber · bends

Marine grade. For boats, ocean-front rails and anything that lives in the spray.

Aluminium 5052-H32

Fiber · bends

Bends without cracking and shrugs off salt. The default for enclosures and boat parts.

Aluminium 6061-T6

Fiber

Stiff and machinable — flat plates, mounts, jigs. It cracks on a tight bend: choose 5052 to bend.

Brass 260

Fiber · bends

Warm gold that patinas. Nameplates, inlays, trim.

0.5 mm0.8 mm1 mm1.6 mm

Copper 110

Fiber · bends

Bus bars and art. Reflective — thin gauges only on the fiber.

0.5 mm1 mm

Cast acrylic

CO₂

Flame-polished edges straight off the laser. UV-stable cast sheet — fine in the sun.

1.5 mm3 mm4.5 mm6 mm10 mm

Baltic birch plywood

CO₂

Void-free and crisp to engrave. Edges come off the laser toasted brown.

3 mm6 mm9 mm12 mm

Koa veneer plywood

CO₂

Hawaiian koa face veneer on a birch core. Special order; engraving reads beautifully.

3 mm6 mm

MDF

CO₂

Cheap and flat — jigs, templates, prototypes. Swells in humidity: keep it indoors.

3 mm6 mm9 mm

Delrin (acetal)

CO₂

Slippery and tough: gears, bushings, wear strips.

1.5 mm3 mm6 mm

HDPE marine board

Router

UV-stabilised starboard: never rots, never rusts. Boat hatches, cutting boards, outdoor signs.

Plywood (router)

Router

Furniture, shelving, stage sets. Edges sanded on request.

Aluminium composite (ACM)

Router

Rigid, light sign panel that takes the weather.

3 mm6 mm

Local hardwood (koa, monkeypod, mango)

Router

Island-grown slabs, sourced per job — or bring your own board. Priced at quote.

3D printing

PLA

Indoor

Crisp and cheap. Softens in a hot car and fades in the sun — indoor parts.

PETG

Indoor

Tougher than PLA, handles heat better. Good for functional parts.

ASA

Outdoor

UV-stable — the outdoor plastic. Mounts, housings, anything in the Hawaiʻi sun.

TPU 95A

Outdoor

Rubbery and tough: gaskets, bumpers, grips.

Nylon-CF (PA-CF)

Outdoor

Carbon-filled nylon on the hardened-nozzle Bambus: stiff, strong, heat-tolerant.

Standard resin

Resin

Fine detail — miniatures, prototypes, visual models.

Clear resin

Resin

Polishes to glass-like clarity: light pipes, lenses, fluidics.

Tough resin

Resin

ABS-like toughness with resin detail. Snap fits, enclosures.

Nylon 12

Outdoor

The all-rounder: strong, slightly flexible, watertight at 2 mm walls. Housings, brackets, end-use parts.

Nylon 11

Outdoor

Tougher and more ductile than PA12 — takes impacts and living hinges. Plant-based.

Nylon 12 GF (glass-filled)

Outdoor

Stiff and heat-stable: jigs, fixtures, parts that must not flex.

Nylon 11 CF (carbon-filled)

Outdoor

The strongest powder: drone arms, robot parts, metal replacement.

TPU 90A

Outdoor

Rubbery and resilient with no supports: seals, grips, lattices, shoe soles.

Boards

Solder mask
GreenBlueBlackWhiteRedPurpleYellow
Finishes
  • Lead-free HASL — Solder-dipped. Cheapest, fine for most through-hole and SMD.
  • ENIG — Flat gold over nickel. Fine-pitch parts, edge contacts, salt air.
  • HASL (leaded) — Easiest to hand-solder. Not RoHS.
