Printed Materials for Passive-RF Hardware

Driven by system requirements we work with customers to identify the best material and processes for each design. Typical solutions include Ti Gr 23 with optional silver coating, AlSi10Mg, 6061-RAM2, Scalmalloy, or Cu.

Passive RF Materials

Pushing the Boundaries of Passive RF Hardware Design

  • Airbus Monolithic DMP Part Cutaway

  • Monolithic Design for Reduced Part Count

    Simplify complex RF hardware to reduce part count and eliminate costly assembly, test, and integration steps. Direct metal printing (DMP) helps our customers impact system level performance by reducing assemblies into single monolithic structures.

  • Martijn's antenna 3different views

  • Smaller Part Footprints

    Increasing the capacity for multiple beams within a single satellite is a major industry trend. While reduced weight drives major improvements, volume is also mission critical. Better packaging efficiencies allow more channels for more services within the limited satellite design volume.

  • Smooth Surface Topology

    Machined surfaces have sharp peaks and troughs, while 3D printed surfaces are made of spheroids melted together for a smooth surface topology. Testing has demonstrated that additively manufactured RF components can perform as well or better than machined surfaces even with higher Ra values. Additive manufacturing enables the ability to shape a part for more effective signal filtering with an optimized surface topology.

Case Study: Low Profile, Low Mass Metasurface Antennas

In collaboration with NASA’s Jet Propulsion Laboratory and the Univ Rennes, CNRS, IETR - UMR 6164, 3D Systems produced several thousand elements of this MTS antenna on a single base plate. Low profile and low mass make this an ideal Ka band antenna type for SmallSats and CubeSats.
