3D-printed lenses fresh (and wet) from the printer look clear, but have tiny surface imperfections that must be dealt with.

These materials and printing processes enable the use of high-resolution, scalable 3D-printing for complex RF dielectric components such as gradient index (GRIN) lenses or three-dimensional circuits.

Bambu Lab recently released the large-format H2D 3D printer. While I gave it a positive review, I did have some issues with ...
