Revo Micro's small size is made possible by a manufacturing process that gives it titanium like performance – the strength and low thermal conductivity of titanium, without being titanium. Lightweight construction makes it ideal for squeezing extra motion system speed performance from your machine. - Works with Revo HeaterCore and Revo Nozzles – change nozzles without tools and hot tightening! - Titanium like performance – the strength and low thermal conductivity of titanium, without being titanium! - Anodised black aluminium heatsink keeps things cool and looks cool too - Lightweight construction takes the strain off your motion system for greater speed performance
