Clear coating
It is a post-processing technique commonly applied to parts to obtain a cosmetic finish. As painting is
also possible on 3D-printed parts, a little polishing is often needed to make the surface smooth, after
which the piece can be painted with whatever colors you like. You need to get the Pantone numbers with
your design upload, along with a CAD model showing which color goes where and the parts can be sprayed
with an automotive-grade paint or Soft-touch painting for an attractive finish.
Plating
Plating is required on 3D-printed parts to increase strength and durability. Electroless nickel plating
can make a cast aluminum or magnesium part look more elegant and suitable for lightweight applications.
Dyeing
Stereolithography (SLA), selective laser sintering (SLS), Multi Jet Fusion (MJF), and PolyJet parts can
be dyed black, green, red, blue, or yellow. The finished pieces are only briefly exposed to a hot dye to
achieve a prominent color. This is one of the quickest and most cost-effective ways to make printed
parts look more appealing.
Decaling
You can personalize a part by adding company logos, safety warnings, and other graphics. Adhesive and
thermal-transfer decals frequently do not adhere to the rough surface of some 3D-printed parts, so
sanding or smoothing is required before deciding.
Texturing
Making 3D-printed parts less slippery improves their finish, ergonomics, and cosmetic appearance. To
enhance weather and sun resistance on the UV-curable materials used with SLA, this technique can apply a
soft-touch paint or urethane clear coat to a 3D-printed part.
Polishing
It is practiced with 3D-printed parts to achieve a high-quality finish. Smoothing is frequently required
when applying paint and decals. However, If a higher finish is a requirement, then you need to specify
your finish expectations, and the manufacturer can do it for you.
Heat treating
It is ideal for removing heat-induced stress and potential warping from metal parts created with direct
metal laser sintering (DMLS). It also hardens, strengthens, and prevents cracking and fatigue in DMLS
metals. If you need a 3D-printed metal that is extremely tough and hardened, stainless steel 17-4 PH is
the best option.
Many post-processing options are available, and depending on the material type and requirement, the best
technique is selected and applied to the 3D-printed part to achieve the desired finish.
