A printed part fresh off the bed looks printed. Finishing is what makes it look like a product. It’s also where most studios cut corners, and where we don’t.

Process by material

  • FDM (PLA, PETG, ABS): fill layer lines with primer-filler, sand to 600 grit, then paint.
  • SLA / DLP resin: already smooth; primer once, paint twice.
  • SLS nylon: porous; needs sealer before paint takes evenly.

Send the part (or print it with us) and tell us the desired finish. We’ll quote per part with no minimum order.

What's included
  • Sanding and primer prep
  • Pantone-matched spray paint

  • Clear coat (matte, satin, gloss)
  • UV-cured topcoats for outdoor durability
How we make it
  1. Surface prep

    Wet-sand layer lines and seam marks. Mask off the parts that should stay raw. Skipping this step is why most printed parts still look printed.

  2. Primer fill

    Filler primer in a downdraft booth, sanded back to 600 grit. The substrate is invisible by the time we move on to colour.

  3. Base coat

    Pantone-matched spray or 2-pack auto paint, depending on durability needs. Even tone, no orange peel, no runs.

  4. Detail & weathering

    Airbrush gradients, panel-lining, micro highlights, weathering, the difference between a toy and a hero unit.

  5. Clear coat

    Matte, satin, or gloss clear locks the colour and adds UV protection. Hand-polished where the surface needs to look wet.

Frequently asked

How much does it cost to electroplate a 3D-printed part in Singapore?

Electroplating runs S$60 to S$100 for a chrome or copper finish on a hand-sized part, and S$100 to S$180 for gold or antique. It looks and feels like real metal because it is, plated over a 3D-printed master that needs specific surface prep first. This is the workhorse finish for trophies and awards, chrome or gold over a printed master for premium presentation. We quote per part with no minimum order.

Can you match my exact brand colour on a sprayed part?

Yes, we spray to your Pantone code so the colour is brand-accurate. Pantone-matched spray with a satin clear coat costs S$30 to S$80 per hand-sized part and ends up looking like an injection-molded prototype. For parts that take handling or sit outdoors we switch to two-pack automotive paint or add a UV-cured topcoat to survive the Singapore sun.

Do you do airbrush weathering and detailing on scale models and figurines?

Yes, airbrush detailing covers fine gradients, panel-lining, micro highlights, and weathering, the work that separates a hero unit from a toy. It runs S$40 to S$120 per hand-sized part depending on how much detail the piece needs, then we seal it with a matte clear coat. Send the model or print it with us and tell us the look you want.

Which finish should I pick for my job?

It depends on the part. Trophies and awards suit electroplated chrome or gold (S$60 to S$180), product mockups want Pantone-matched spray with satin clear (S$30 to S$80) to read like a molded prototype, and scale models call for airbrushed gradients sealed with matte clear (S$40 to S$120). Outdoor signage and props get a UV-cured topcoat. Send the part and your intended finish to our Bendemeer studio and we return a quote per part, usually the same business day.
