Lay Filaments Di-Electro-LAY Filament 1.75mm 0.10kg 72% TiO2

Experimental electromagnetic filament

This 1.75 mm polymer filament contains 72 % titanium dioxide and is supplied as a 0.10 kg spool. It is designed for researchers and advanced makers who need printed parts that respond strongly to electromagnetic fields. The material suits experimental antenna prototypes, sensor housings and RF test structures. Its niche behaviour makes it unsuitable for general structural printing.

High filler content and handling

The 72 % TiO2 loading gives the filament distinct electromagnetic properties but also makes it more abrasive and brittle than standard polymers. A hardened nozzle is advisable and gentle spool handling reduces the risk of snapping during long prints. No special bed surface is mandated by the supplier, though good first-layer adhesion remains important for dimensional accuracy in RF parts.

Upgrade from standard plastics

Makers moving from ordinary PLA or ABS gain the ability to print components that interact with electromagnetic fields rather than simply insulating them. The jump is worthwhile when a project demands custom waveguide geometries, near-field probes or experimental antenna elements that cannot be machined easily. It is not a replacement for mechanical-load parts or high-temperature applications.
