Why ColoradoKote for AM Post-Processing
Complete workflow for every AM material and technology
Full-spectrum AM material coverage
ColoradoKote maintains validated protocols for every common AM substrate. Polymer materials include PA12, PA11, and MJF nylon. Metal materials include Ti-6Al-4V titanium, AlSi10Mg aluminum, Inconel, and 316L stainless steel. AM technologies covered include SLS (selective laser sintering), MJF (Multi Jet Fusion), and PBF-LB/DMLS (metal powder bed fusion). Each material class follows its own preparation sequence, blast media selection, pressure parameters, and cure profile. No generic one-size-fits-all approach.
Surface finish and protection in one coating step
Cerakote fills micro-porosity inherent in powder bed fusion processes, reducing surface roughness from Ra 8-15 micrometers to below 3 micrometers measured by stylus profilometer. Simultaneously, the ceramic-polymer matrix delivers corrosion resistance of 3,000+ hours (ASTM B117) on metal AM substrates, 8H-9H pencil hardness (ASTM D3363), and 100+ color options. Vapor polishing, tumbling, and infiltration each address one finishing requirement. Cerakote addresses surface finish, protection, and aesthetics together.
Dimensional integrity across every AM geometry
Thin-film application at 0.5-2 mils adds only 0.001 to 0.002 inches per coated surface. CMM measurement on every production batch confirms parts remain within plus or minus 0.005 inches. Lattice structures, conformal cooling channels, snap fits, and lightweighted brackets maintain their designed geometry. Powder coating at 3-5 mils forces post-machining that eliminates topology-optimized features and adds cost back into the production chain.
Transparent capacity with certified documentation
Dedicated AM post-processing capacity of 200 parts per week with standard turnaround of 7-10 business days and expedited service at 3-4 business days. Capacity data is published because AM production managers need vendor transparency, not vague lead time promises. Every order ships with a Certificate of Conformance documenting before-and-after Ra measurements, dimensional verification, material batch records, and cure parameters. AS9100 documentation covers aerospace AM. ITAR registration covers defense AM.
AM Post-Processing Specifications
How We Post-Process AM Parts
Material-specific protocols from raw build to production-ready component
Material Identification and Substrate Preparation
Every AM part begins with material and build technology verification: PA12 (SLS), PA11, MJF nylon, Ti-6Al-4V (PBF-LB/DMLS), AlSi10Mg, Inconel, or 316L stainless. Polymer parts receive compressed air blasting to clear embedded powder, followed by fine glass bead blasting at 40-50 PSI. Metal AM parts undergo ultrasonic cleaning to remove partially sintered particles, then aluminum oxide blasting at 50-60 PSI with targeted attention to support structure contact areas. Post-blast CMM measurement establishes baseline dimensions before coating. Selective masking protects threaded holes, datum surfaces, and critical mating features identified on engineering drawings.
Thin-Film Cerakote Application with Material-Specific Curing
Cerakote is applied via calibrated HVLP equipment in a climate-controlled spray booth monitored for temperature (plus or minus 5 F) and humidity (plus or minus 10%). DFT gauges verify coating thickness at 0.5-2 mils during application. Tight-tolerance parts receive 0.5-1.0 mil for maximum dimensional preservation. Cosmetic-priority parts receive up to 2.0 mils for maximum surface smoothing. Polymer substrates cure at 250 F, below PA12 heat deflection temperature, preventing warping on thin-walled features. Metal AM substrates cure at 250-300 F per standard Cerakote profiles. Multiple thin coats prevent buildup and sagging on complex AM geometries including lattice structures and internal channels.
Multi-Point Inspection and Production Documentation
Post-coating inspection covers five verification points: coating thickness (DFT gauge), adhesion (ASTM D3359), surface roughness (stylus profilometer, target Ra below 3 micrometers), color consistency (spectrophotometer, Delta E at or below 1), and dimensional tolerance (CMM, plus or minus 0.005 inches). Before-and-after Ra documentation shows the measurable surface roughness improvement for every order. Certificate of Conformance ships with every batch, including material traceability, process parameters, cure records, and all inspection results. Aerospace AM parts receive full AS9100 documentation with first article inspection reports available upon request.
Proven AM Post-Processing at Production Scale
AM post-processing performance is verified through dimensional measurement, surface roughness testing, and standardized ASTM protocols, not manufacturer claims. ColoradoKote documents results on every production batch under AS9100 and ISO 9001 controls, and all data ships on your Certificate of Conformance with full lot traceability.
200 parts per week, documented and verified
ColoradoKote processes 200 AM parts per week across polymer and metal substrates with material-specific protocols for PA12, PA11, MJF nylon, Ti-6Al-4V, AlSi10Mg, Inconel, and 316L stainless steel. Surface roughness consistently reduces from Ra 8-15 micrometers to below 3 micrometers, measured by stylus profilometer on every batch. Dimensional tolerances hold within plus or minus 0.005 inches, verified by CMM. Standard turnaround is 7-10 business days, with expedited service at 3-4 business days for production deadlines that cannot move.

Frequently Asked Questions
Find answers about our coating processes and technical capabilities
Yes. Our spectrophotometer-verified color matching creates a documented color standard for your program that we reference on every production run. Delta E within 1.5 ensures parts coated today match parts coated months or years from now. This level of consistency matters for aircraft cabin interiors, branded equipment, and any application where batch-to-batch color variation is unacceptable.
Surface preparation is the most critical variable in coating corrosion performance. Industry data consistently shows that 60-80% of coating failures trace back to inadequate surface preparation, not coating material failure. ColoradoKote achieves SSPC-SP 10 near-white blast with 2-4 mil anchor profile as standard, which is why our Cerakote applications consistently deliver salt spray resistance exceeding 3,000 hours. The preparation determines the result.
Yes. Cerakote's smooth, sealed surface resists marine biological adhesion better than rough, porous raw AM surfaces. When biofouling does occur, the coating withstands the aggressive chemical cleaning agents used for marine maintenance without degradation. For AM parts deployed in submerged or splash-zone applications, the sealed Cerakote barrier prevents salt water from penetrating AM surface porosity, which would otherwise create subsurface corrosion that undermines the part from within.
ColoradoKote is located in Johnstown, Colorado, along the Northern Colorado aerospace and defense manufacturing corridor. We are 50 miles north of Denver, 100 miles north of Colorado Springs, and 40 miles south of Cheyenne, Wyoming. We serve aerospace, defense, and industrial clients nationwide, receiving and shipping parts throughout the United States via standard freight and expedited carriers.
Yes. Fertilizer crystallization, herbicide residue, and pesticide deposits accumulate in sprayer nozzles, valve internals, and pump housings. These chemical deposits corrode metal surfaces and prevent coating adhesion if not fully removed. Ultrasonic cavitation at 40 kHz dissolves and dislodges these deposits from flow passages, orifices, and internal geometries that flushing alone cannot clean. Clean sprayer components accept Cerakote or polymer coating with full adhesion for lasting chemical protection through subsequent growing seasons.
