1. A method for additively manufacturing a waveguide utilizing an additive manufacturing system, the method comprising:
providing a build plate comprising a base, and one or more build surfaces oriented on an angle relative to the base;
successively layering material on the build plate in a build direction normal to a surface of the base, wherein the successive layering comprises:
forming a channel comprising an outer wall defining an inner cavity configured to propagate electromagnetic waves;
forming a filter disposed in the inner cavity of the channel, the filter comprising a perimeter edge, an aperture, and a downward facing surface relative to the base of the build plate; and
forming a support bridge comprising a first interface connected to an inner surface of the outer wall at a first location, and a second interface connected to the filter at a position between the perimeter edge of the filter and the aperture in the filter to support the downward facing surface of the filter within the channel.
