Post-Processing & Painting Your 3D Prints — The UAE Hobbyist's Complete Finishing Guide
The print comes off the machine. What happens next determines whether it looks like a professional display piece or an obviously amateur hobbyist print.
Understanding post-processing is the single biggest gap between hobbyists who are happy with their 3D prints and those who are disappointed. This guide closes that gap.
The Three Finish Tiers — What You Get at Each Level
Tier 1 — Raw Print (Included in Base Price)
What it is: Your model straight from the printer. Supports removed, basic resin or stringing cleanup done.
SLA resin raw prints: Already have a smooth surface. Layer lines are essentially invisible to the naked eye. Paint can be applied directly, though primer is still recommended for adhesion.
FDM raw prints: Have visible layer lines at 0.2mm resolution — each line is a ridge that will be emphasised by painted colour if not addressed. For display pieces, post-processing is strongly recommended before painting.
Best for: Experienced painters who have their own prep workflow. Tabletop terrain pieces that will be dry-brushed at viewing distance. Functional parts where appearance is not the priority.
Tier 2 — Sanded and Primed (Add AED 20–50 Depending on Size)
What it is: We sand the print to remove or reduce layer lines, then apply grey primer evenly across all surfaces.
For SLA resin: Light sanding removes any slight stepping from support touchpoints, primer creates a consistent grey surface for clean colour application.
For FDM: Typically 120→240 grit sanding, one or two coats of filler primer, light sand between coats. Result: a near-smooth surface that accepts paint cleanly.
Best for: Hobbyists who want to paint their own models but prefer to skip the prep work. Miniatures where you want clean colour coverage. Cosplay props intended for convention display.
Tier 3 — Fully Painted (Price on Request)
What it is: Our painting team completes your model to tabletop or display standard. Base colours, wash shading, layer highlights, and fine detail work.
For miniatures: We work from reference images or your specification — colour for armour, skin tone, cloth, weapon effects. Tabletop-standard (optimised for 3-foot viewing distance) or display-standard (optimised for close examination and photography).
For cosplay props: Stage-ready colour, weathering, battle damage effects as specified.
Best for: Display collectors, gifts for non-painters, convention-ready cosplay pieces, and presentation models.
Material-Specific Finishing Guide
Finishing SLA Resin Miniatures
SLA resin is the miniature painter's ideal starting surface:
- Wash in isopropyl alcohol (IPA) — removes uncured resin residue
- UV cure — fully hardens the print
- Sand touchpoints — smooth any support contact marks with 400+ grit
- Grey primer — Vallejo, Army Painter, or any fine-surface model primer
- Base colours — acrylic paints (Citadel, Vallejo, Army Painter all work perfectly)
- Wash/shade — Nuln Oil or Agrax Earthshade for shadow and depth
- Layer highlights — progressively lighter mix of base colour
- Varnish — matte varnish (Testor's Dullcote) to protect and unified sheen
Finishing FDM Props and Cosplay
- Rough sand — 80→120 grit to knock down highest layer ridges
- Filler primer — automotive rattle can, 2–3 coats
- Sand between coats — 240 grit between primer coats
- Final sand — 400→600 grit for near-smooth surface
- Colour base coat — rattle can or airbrush
- Detail paint — hand-painted details, logos, insignia
- Weathering (optional) — dry brushing, washes, battle damage
- Clear coat — satin or matte depending on desired finish
UAE-Specific Painting Tips
The UAE climate affects painting in ways that guides written for the Northern Hemisphere do not cover:
Primer in the heat: Do not apply rattle-can primer in direct sunlight or above 35°C. The solvent flashes too rapidly, leaving a rough orange-peel texture. Paint indoors with AC or early morning outdoors before the heat peaks.
Humidity in summer: Dubai's summer humidity works against water-based acrylic paints — they can take longer to dry and the working time on the brush shortens noticeably. In summer, thin paints slightly more than usual and allow longer drying time between layers.
Storage: Resin-printed models should be stored away from direct sunlight — UV degrades standard printing resin over time, causing yellowing and eventual brittleness. FDM models in ASA or PETG are UV-stable for outdoor display.
Ready for Display Without Painting? — Color Jet Printing
For gifts, collector pieces, and display models where you want colour without the painting process — our Color Jet 3D printing produces full CMYK colour output directly from the printer. No painting required, no primer required. The colour is embedded in the material.
Color Jet is ideal for: anime figurines with specific colour designs, portrait figurines, architectural display models, and any project where the colour must precisely match a reference.
