Impact Coating™
Empire Group USA is a U.S.-based, ISO 9001:2015-certified, and ITAR-registered custom manufacturer specializing in HP multi-jet fusion (MJF) 3D printing, including durable coatings for MJF PA12. Impact Coating™ is our proprietary post-processing finish designed specifically for HP MJF PA12 parts, transforming them into durable, presentation-ready components with enhanced surface properties.
Learn more about how Impact Coating™ delivers production-quality 3D-printed parts and how working with a dedicated low-volume manufacturing partner benefits your overall program.
What Impact Coating™ Improves
While HP multi-jet fusion technology creates dimensionally stable nylon components, raw surfaces often retain a matte, granular texture from the powder bed. Visible layer lines, surface porosity, and slight color variations are common across low-volume batches. These superficial characteristics can make a functional component look like an early-stage prototype rather than an end-use part.
Impact Coating™ eliminates these aesthetic and physical limitations. As part of our comprehensive custom finishing and assembly services, this proprietary HP MJF PA12 finishing service is engineered to address four key performance areas:
Surface finish. This application reduces powder-grain textures, resulting in a smooth, uniform surface across complex geometries.
Scratch resistance. The hardened coating chemistry protects components against abrasion during assembly, shipping, and rugged field handling.
Multi-color finishing. We support custom, color-specific aesthetics beyond standard gray or black for branded hardware and customer-facing components.
Cosmetic consistency. As a form of cosmetic finishing for additive manufacturing, this process creates a uniform appearance across entire production runs, reducing part-to-part variation common in manually dyed outputs.
Built Specifically for HP MJF Additive Manufacturing
At Empire Group, we developed Impact Coating™ after years of working with HP multi-jet fusion technology and supporting customers who needed more than just functional prototypes.
Many additive manufacturing parts do not move into deployment because they still look like 3D-printed samples. Impact Coating™ helps close the gap between prototype and production by improving the visual and tactile quality of MJF PA12 components.
For engineering teams evaluating vapor smoothing alternatives for PA12, Impact Coating™ provides repeatable surface refinement without compromising critical tolerances. This makes it ideal for:
Low-volume production parts
Robotics enclosures and housings
Aerospace and defense components
Medical device prototypes
Consumer product development
Trade show and investor presentation models
Functional prototypes requiring a premium cosmetic finish
Low-Volume Manufacturing with Production-Level Finishing
Hard tooling and injection molding require substantial upfront capital investments and extended lead times, so committing to permanent molds too early can stall development budgets. That’s where Empire Group can help. As your low-volume manufacturing partner, we provide production-quality 3D-printed parts to keep your initial production agile and cost-effective.
In addition to our specialized HP MJF printing services, we provide PA12 finishing services like Impact Coating™, light assembly, painting and coating, and quality control inspection entirely in-house. By streamlining both fabrication and finishing under one roof, we help minimize program risk and accelerate your path to market.
Why Surface Finish Is a Strategic Decision
A component that functions perfectly but looks unfinished can inadvertently create business problems. Stakeholders and procurement managers often evaluate hardware visually before assessing its technical merits. A cosmetically unrefined component can stall critical approvals, delay commercial adoption, and lower overall program confidence.
Impact Coating™ overcomes this hurdle by making low-volume nylon parts look and perform like production-run injection-molded parts. Product teams can run functional field tests, present polished assemblies to decision-makers, and gather realistic user feedback before committing to a production-scale mold. By pairing premium surface treatments with low-volume manufacturing, we provide a streamlined, single-source manufacturing pathway.
