• Telemeter Electronic is pushing electromagnetic absorber design into everyday FFF with a new filament tuned for automotive radar frequencies. • As vehicles add more radar and higher frequency sensor packages, labs and integrators keep running into the same practical problem: absorber parts rarely fit the geometry they actually need. • Traditional absorber foam and machined fixtures work, but they are often bulky, slow to iterate, and awkward around complex housings and tight measurement setups. • Additive manufacturing has been working on this problem for years, mostly through custom fixtures, housings, and antenna mounts produced on desktop machines. • The missing piece has been material performance: common polymers can form the shape, but they do not really dampen electromagnetic energy in the right bands. • Telemeter’s answer is a new 1.75 mm filament, described as a 3D printable absorber targeting the 76 to 81 GHz automotive radar band, while also covering millimeter wave applications from 50 to 100 GHz.
