Optisys LLC, a provider of 3D-printed metal micro-antenna products for aerospace and defense applications, recently completed a project that documents the advantages of employing additive manufacturing (AM) to produce such systems for aerospace and defense purposes.

​The test-piece demonstrator project involved a complete redesign of a high-bandwidth, directional tracking antenna array for aircraft (known as a Ka-band 4×4 Monopulse Array). Optisys performed every aspect of the design work in-house and printed the component in a single piece on its Concept Laser machine, Optisys reports.

Optisys conducted a profitability analysis on how their redesigned microwave antennae test piece compared to a legacy design that is traditionally manufactured. By optimizing their design for additive manufacturing, Optisys says it realized the following benefits:

  • part count reduction from 100 discrete pieces to a 1 piece integrated assembly;
  • weight savings of over 95%;
  • lead time reduced from 11 months to 2 months;
  • production costs reduced by 20% to 25%; and
  • non-recurring costs reduced by 75%.
Optisys says it can print in a variety of metals with its Concept Laser machine, though for antenna products they prefer aluminum because of its surface conductivity, light weight, corrosion resistance and strength under shock and vibration.
