Inconel, an extremely strong and corrosion-resistant nickel-chromium superalloy, opens up new possibilities for EMC shielding of ventilation openings through 3D printing technology. Traditional honeycomb filters are often vulnerable to mechanical damage, but with additive manufacturing, these limitations are a thing of the past. Thanks to 3D printing, Parker Chomerics can create robust, complex geometries without the structural weaknesses of conventional manufacturing methods.

• With Inconel 3D printing, Parker Chomerics develops EMC honeycomb filters as a single homogeneous part, offering significant advantages:
  
• No secondary operations – faster production and fewer assembly steps
  
• Maintained filter effectiveness up to 24GHz, compared to traditional honeycombs whose performance drops around 4GHz
  
• Improved ventilation performance – optimal airflow and shielding
  
• Reduced risk of Foreign Object Damage (FOD) – no burrs or weak components
  
• Greater design freedom – custom solutions without standard material limitations

By no longer being constrained by fixed material dimensions, engineers can precisely tailor the honeycomb structure to the desired shielding and ventilation requirements. For example, larger cells can be applied for improved airflow, or customized shapes and sizes can be developed for specific enclosures. Even non-flat and complex surfaces are possible, allowing for bespoke ventilation solutions within reach.

With Inconel 3D printing, structural integrity, design flexibility, and enhanced EMC shielding are combined into one advanced solution.
