Spray Paint Colour Catalogue
Spray painting is how we put accurate, even colour onto a 3D print, a prop or a signage letter. We carry 30 plus stock colours covering primaries, metallics (chrome, gold, copper, brass), neons and matte tones, and for anything brand-specific we mix to your Pantone code using a 2-part automotive paint system. Pantone-matched spray with a clear coat runs S$30 to S$80 per hand-sized part, and the finished piece reads like an injection-moulded prototype rather than something off the printer bed.
Stock colours and custom mixes
The stock range covers most jobs straight away:
- Primaries and brights: reds, blues, greens, yellows, plus neons for display work.
- Metallics: chrome silver, gold, copper and brass for a sprayed metallic look.
- Matte tones: flat blacks, greys and whites for product mockups and architectural models.
If you need an exact brand colour, send the Pantone code at quote time and we confirm whether it is stock or needs a custom mix. The 2-part automotive paint cures harder than a spray can and is the right call for parts that get handled often.
Here is the full stock range, plus our fluorescent, metallic and special finishes:

Standard colours: over 60 stock shades, named and numbered.

Fluorescent colours for display and high-visibility work.

Metallic colours, formulated with aluminium flakes for extra sparkle.

Special finishes: heat-resistant paints and anti-rust primer.
Primer, base coat, clear coat
Good colour starts under the colour. A printed part fresh off the machine still shows layer lines or seam marks, so we wet-sand, fill with primer and sand back to 600 grit before any colour goes down. The substrate is invisible by the time we spray the base coat. We then lock it in with a clear coat in your choice of sheen:
- Matte: flat, no glare, suits scale models and signage.
- Satin: soft sheen, the usual pick for product mockups.
- Gloss: wet, mirror-like, hand-polished where needed.
When to spray, electroplate or UV print
Spraying is not always the right finish, so we match the process to the job:
- Spray paint for accurate colour across the whole part: props, product mockups, scale models, signage.
- Electroplating when you want real metal weight and shine: trophies and awards in chrome (S$60 to S$100) or gold (S$100 to S$180) over a printed master. See our Glenfiddich antlers project for that finish in use.
- UV print for flat artwork, logos and photographic detail directly on a surface, from S$10 to S$40 per part.
For brand colour with a clean even tone, spraying wins. For a cast-metal look, plating wins. Full ranges sit on the pricing page.
Durability and outdoor use
Standard spray and clear coat handle indoor display and normal handling without trouble. For parts that sit outside or take the Singapore sun, we switch to 2-part automotive paint and add a UV-cured topcoat so the colour does not chalk or fade. Tell us where the piece will live and we spec the topcoat to suit. Touch-dry takes 15 to 30 minutes, with full cure at 24 hours, so painted work adds one to two days on top of the standard 5 to 7 working day print lead time.
What it costs and how to start
Finishing is quoted per hand-sized part with no minimum order:
- Sand and primer: S$15 to S$30

Frequently asked
What spray paint colors does Additive Inn stock?
We carry 30+ stock colors covering primaries, metallics (chrome, gold, copper, brass), neons, and matte finishes. For exact Pantone matching, we mix custom colors using a 2-part automotive paint system. Send your Pantone code at quote time and we'll confirm whether it's stock or needs a custom mix.
How long does spray paint take to dry on 3D prints?
Touch-dry in 15–30 minutes. Recoat after 1 hour. Fully cured (handleable without damaging the finish) in 24 hours. Two-pack automotive paint cures harder than spray-can paint and is the right choice for parts that will be handled often. Add 1–2 days to the lead time for painted finish work.
Will spray paint stick to PLA, resin, or PETG?
Yes to all, with primer. PLA and ABS take primer easily. SLA resin needs a thorough wash (IPA + post-cure) before priming or paint will fish-eye. PETG is the trickiest, and needs a flexible primer or it'll crack. We use a tinted automotive primer that adheres to all standard 3D printing materials.
