The trick lies in performing the join in a space only marginally wider than the filament width, in the case of 1.75 mm filament a short piece of 1.775 mm PTFE tube encased in a 3D printed clamp.

Nanoe has launched Zetamix TiO2, a sintered ceramic filament for radio frequency (RF) applications. The 1.75 mm Zetamix TiO2 filament is available in 500 g spools.

By the time the filament reaches the end of 40 foot bath, it has been gently stretched to its final 1.75 mm diameter. After the water bath, the filament travels through a pair of lasers to check ...
