For some users it will &ldquo, payback&rdquo, after first use! For UM2/ UM2+ Description This fantastic newly developed product by 3D Solex has a core of stainless steel and a multi-component molecularly interlocked tempered surface with 2 main advantages: 1) PLA ( or any other filament we know of ) simply refuses to stick to it. 2) Cold pulls work so much better, the inside of the nozzle is &ldquo, ICE&rdquo, too. 3) Its surface is much more wear resistant than that of stainless steel, so it will last much longer printing abrasive filaments. Compared with brass, &ndash, it is in a class of its own. It also works exceptionally well with chemically challenging chemicals, like glow, flexible materials, + many more. These are the three fantastic advantages of this nozzle. Now blobs of filament will not be carried around and deposited on your print. It still prints slower than a brass nozzle.
