An antenna bracket is primarily made by Metal Additive (DMLS/SLM). Metal 3D printing (DMLS/SLM) fuses metal powder with a laser layer by layer to build dense metal parts of complex geometry. Below is the full route to make an antenna bracket, the materials it suits, the tolerances to expect and the main design points. The route is free, from the finder.

Step by step

How an antenna bracket is made

The usual route, raw material to finished part. The amber step is where the antenna bracket gets its basic shape.

  1. CAD and slicing

    Prepare the 3D model, orient the antenna bracket and generate supports and layers.

  2. Metal Additive (DMLS/SLM)

    Build the antenna bracket layer by layer.
    Tooling None   Tolerance ±0.1 to 0.3mm   Lead 1 to 3 weeks

  3. Support removal

    Take the part off the plate and remove the supports.

  4. Stress relief and cut-off

    Stress-relieve, then cut the antenna bracket off the build plate.

  5. Machining

    Machine the mating faces, bores and threads: as-built metal is rough.
    Tooling None   Tolerance ±0.125mm, to ±0.025mm   Lead 1 to 10 days

  6. Surface finish

    Bead blast, tumble or sand to the finish you need.

  7. Inspection

    Verify dimensions and, for metal, check density and porosity.

Design tips

General pointers. The full design-for-manufacturing list for an antenna bracket is in the dossier.

  • Large overhangs. Design self-supporting angles.
  • Critical faces as-printed. Add machining stock.
Cost

What an antenna bracket should cost

Metal additive for complex, consolidated or conformal-cooled parts; expensive, justified by geometry you can't machine.
