Aesthetic Finishing for Additive Manufacturing
Precision Cerakote ceramic coatings for aerospace, defense, and industrial components.
The Aesthetic Problem in Additive Manufacturing
Where surface texture blocks end-use applications
The challenge
Harsh environments demand coatings that hold.
The solution
ColoradoKote ceramic coating stops corrosion cold.
Why Cerakote for AM Aesthetic Finishing
Production-grade finish on printed parts
Delta E ≤1 on polymer and metal AM parts
Spectrophotometer-verified color accuracy on PA12, PA11, Ti-6Al-4V, AlSi10Mg, and stainless steel substrates. Multi-material assemblies match to the same color standard regardless of build material or print technology. Anodizing cannot coat polymer AM parts at all, and delivers Delta E greater than 5 on metals.
Surface smoothing at 0.5-2 mils
Cerakote fills the micro-porosity left by SLS and MJF processes, reducing Ra from 8-15 to under 3 micrometers. At 0.5-2 mils, the coating preserves the dimensional tolerances AM production demands, adding only 0.001 to 0.002 inches per coated surface. Topology-optimized features and lattice structures retain their design geometry.
AS9100 documentation for aerospace AM
Aerospace AM programs require full traceability from print parameters through post-processing. Every aesthetic finishing order ships with a Certificate of Conformance documenting material batches, Ra measurements, Delta E readings, thickness data, and cure parameters. First article inspection reports are available for new programs.
200+ colors for end-use applications
The Cerakote catalog provides immediate color availability, including brand-matched custom colors for consumer products and Federal Standard 595 defense colors. One coating process replaces the combination of vapor polishing for smoothing plus painting for color that many AM operations currently use, eliminating a process step and reducing lead time.

How We Deliver Aesthetic Finishing for AM Parts
Material-specific protocols for polymer and metal additive manufacturing substrates
Material Assessment and Surface Preparation
Every AM part begins with substrate identification: PA12, PA11, glass-filled nylon, AlSi10Mg, Ti-6Al-4V, or stainless steel. Polymer parts receive low-pressure aluminum oxide blasting at 30-40 PSI to avoid distortion of thin-walled features. Metal AM parts receive sandblast preparation matched to alloy type, removing support structure witness marks without altering geometry.
Color-Controlled Cerakote Application
Cerakote is applied via calibrated HVLP equipment at 0.5-2 mil thickness. The locked color formula ensures batch-to-batch consistency verified by spectrophotometer against the master standard. Polymer parts cure at 250 F, below PA12 heat deflection temperature, to prevent warping. Metal AM parts follow standard cure profiles at 250-300 F.
Surface Quality Verification and Documentation
Post-coating surface profilometer readings confirm Ra improvement from 8-15 to under 3 micrometers. Spectrophotometer verification confirms Delta E ≤1 color accuracy. CMM measurement validates dimensional compliance. Every order ships with before-and-after Ra data, Delta E readings, and a Certificate of Conformance with full material traceability.
Proven Aesthetic Results for AM Production
Aesthetic finishing performance is measured with instruments, not visual approximation. Surface roughness is documented by profilometer, and color consistency is verified by spectrophotometer on every production batch under AS9100 quality controls. Before-and-after data ships with every order.
Delta E ≤1 color consistency
Verified across PA12, PA11, titanium, aluminum, and stainless steel AM substrates. Multi-material assemblies match to the same color standard, eliminating the visual inconsistency that blocks end-use adoption. ColoradoKote processes 200+ AM parts per week with this standard maintained on every batch.

Frequently Asked Questions
Find answers about our coating processes and technical capabilities
Surgical instruments endure repeated mechanical stress from tissue contact, bone engagement, clamping forces, and tray handling. Cerakote's 9H pencil hardness and 4,000 cycles per mil abrasion resistance maintain the coating's protective barrier and visual appearance through the instrument's full service life. This reduces the frequency of instrument replacement compared to uncoated or conventionally finished instruments.
Coating adhesion requires a chemically clean substrate free of oils, machining fluids, fingerprints, and particulate contamination. Even microscopic contamination creates weak spots where the coating fails to bond, leading to adhesion failure in service. Ultrasonic cavitation reaches contaminants in blind holes, threads, internal passages, and surface porosity that manual cleaning and spray methods miss. This is why ultrasonic cleaning is integrated into our pre-coating preparation for critical applications.

Industrial pumps and valves face a combination of fluid corrosion, particulate abrasion, and pressure cycling that degrades conventional coatings. Cerakote's 3,000-hour salt spray resistance and chemical compatibility with industrial fluids prevent corrosion, while 9H hardness and 4,000 cycles per mil abrasion resistance protect against particulate wear. Our combined passivation-plus-Cerakote stack on stainless steel components provides dual-layer protection for the most demanding service conditions.
Yes. A properly passivated stainless steel surface forms a chromium-rich oxide layer that withstands repeated autoclaving, chemical sterilization, and harsh cleaning protocols. For medical devices needing additional protection against specific chemicals or color-coding for instrument identification, we can apply Cerakote over the passivated surface at just 0.5-2 mils, delivering 3,000 hours of salt spray resistance without affecting sterilization compatibility.
