3D Printing

Enclosures, jigs and prototype parts, printed fast

From filament (FDM) to resin, nylon and metal — six technologies for enclosures, jigs, brackets and functional parts. We can also help design enclosures that fit your board dimensions.

Materials

Pick a printing technology to see the materials it offers. Tap a colour to switch the photo. The estimator uses the same order: technology → material → colour → finishing.

Molten plastic is laid down layer by layer. The cheapest, fastest and toughest option. Layer lines (about 0.2 mm) are visible; parts ship as printed, with no finishing.

PLA+ (high-strength PLA) — Black
PLA+ (high-strength PLA)

Toughened high-strength PLA — more impact-resistant than standard PLA · stiff and dimensionally stable · soft sheen · heat resistance about 55 °C

Use ·
Look-and-feel prototypes, jigs, stands, models, light functional parts
Pros ·
Cracks far less than standard PLA · cheapest and fastest · 23 colours · little warping, fine for large parts
Cons ·
Softens in heat (car interiors, sunlight)
Finishing ·
Print only (no finishing)
Standard 3–4 days · rush 1–2 days
PETG — White
PETG

Tougher than PLA, better heat and chemical resistance · glossy surface · heat resistance about 70 °C

Use ·
Functional parts, enclosures, outdoor and kitchen-side parts
Pros ·
Resists cracking · handles moisture and chemicals · same family as food containers
Cons ·
Stringing marks are more likely · slightly softer than PLA
Finishing ·
Print only (no finishing)
Standard 3–4 days · rush 1–2 days
ABS — White
ABS

The plastic used for appliance housings · matte · heat and impact resistant · heat resistance about 95 °C

Use ·
Device enclosures, car-interior parts, parts near heat sources
Pros ·
Handles heat and impact · easy to sand and glue
Cons ·
Warps and shrinks while printing — large flat plates may bend · weak against UV
Finishing ·
Print only (no finishing)
Standard 3–4 days · rush 1–2 days
TPU — White
TPU

Rubber-like flexible material · stretches and recovers · Shore 95A

Use ·
Gaskets, bumpers, grips, cable protectors
Pros ·
Bends without breaking · absorbs vibration and shock · non-slip
Cons ·
Slow to print so it costs more · not for tight-tolerance parts
Finishing ·
Print only (no finishing)
Standard 3–4 days · rush 1–2 days

Price examples

Per-piece prices from our estimator for test shapes (VAT excluded, before the minimum order). Filament prices assume standard quality · medium infill · supports left on.

Discounts · minimum order

Minimum order $50
Counted separately for filament and for advanced materials (resin, nylon, metal). Small parts can be bundled to reach the minimum together.
Total print order over $100
Once your whole print order (filament and advanced materials together) passes $100, a lower rate applies to all filament parts.
Advanced materials over $250
Once the advanced-material (resin, nylon, metal) total passes $250, all of it is 20% off. Filament (FDM) is excluded from this discount.
Black filament (PLA+ only)
PLA+ in black prints at a rate about 40% lower than other colours — the most economical choice when colour does not matter.
Supports left on (default · filament only)
Filament (FDM) parts ship with supports attached by default, which is cheapest. Choosing removal adds manual labour.
Shipping $4 extra
A $4 shipping fee is added to each order on top of the print price. VAT is extra.

Options

Filament options
Infill (low · medium · high), supports (left on · removed) and lead time (standard · rush). High infill for load-bearing jigs and brackets; low is enough for fit checks.
Filament is print-only
Filament (FDM) parts ship as printed, with no painting or polishing.
Finishing (advanced materials)
Sanding, spray paint (gloss · matte — sky blue · silver · white · red · black), clear coat, clear dyeing (7 colours), black dyeing for nylon, metal polishing. Each material has its own options; the estimator only shows those available.
Lead time
Filament standard 3–4 days · rush 1–2 days. Advanced materials about 8–11 days depending on the material; current order volume adds some time.

How it works

  1. 1Upload a file

    Drop STL or STEP files into the estimator; we read the shape and show a price right away.

  2. 2Pick technology · material · colour · finishing

    The price updates with every choice, along with how much more unlocks a discount.

  3. 3Review & payment details

    We check printability after submission and send payment instructions. If something needs fixing, we tell you how first.

  4. 4Print · inspect · ship

    Dimensions are checked, then parts are padded and shipped by courier. Tracking is sent by e-mail.

File checklist

  • Units in mm — STL saved in inches or cm comes out 25× or 10× too big and the quote goes wrong.
  • Manifold (watertight) mesh — slicers fill holes arbitrarily, so run a repair pass before exporting.
  • Fit clearance — leave 0.2–0.3 mm per side where a board or part slides in, so nothing has to be forced.
  • Minimum wall — 1.2 mm for filament, 0.8 mm for resin, 1.0 mm for nylon. Thinner walls tear or warp while printing.
  • STEP is welcome too — if the design needs a tweak, having STEP makes it much faster.

No STL? We design board-fit enclosures

KEMI is also a PCB design house. Send your Gerber files or board dimensions and we design an enclosure with connector cut-outs, mounting holes and LED windows, then print it. If we made or ordered the board for you, we use its files directly.

FAQ

Can I order just one piece?

Yes. As long as the $50 minimum (filament and advanced materials each) is met, quantity 1 is fine.

I'm not sure which material to pick.

PLA+ for fit checks and jigs, PETG/ABS or nylon for tough functional parts, resin for smooth looks and small precise parts, SUS316L when you need metal strength. See the uses and pros/cons above, or tell us the use case in your request.

Do you paint filament parts?

Filament (FDM) is print-only. For painting or sanding, choose a resin material and add finishing.

Will the colour match the photo?

Material photos are renders, so colour and texture may differ from the real part. If exact colour matters, choose paint finishing or note it in your request.

Is my file safe?

Files are used only for quoting and printing and are never shared. Files from requests that do not proceed are deleted on request.
