Enabled by a unique dual heater configuration of 200 W, Prime melts filament fast for a maximum volumetric flow rate of up to 116 mm3/s, (516 g/hr), with PLA and 64 mm3/s, (280 g/hr) with TPU.
Building on Mosquito’s Legacy
As an extension of the Mosquito line of hotends, Mosquito Prime features a copper alloy hot block rated to 500°C for ultimate material compatibility and a rigid "roll cage" design for enhanced durability. The Mosquito’s signature Bimetallic Heat Break™ ensures efficient thermal isolation of the cold block to prevent filament clogging.
