While both CPE and CPE+ provide similar performance characteristics

Varying print speeds with different extrusion temperatures can be used

toughness and impact resistance

No PEEK or PTFE Reach Extremely High Temperatures 300ºC with supplied thermistor >400ºC with thermocouple (additional electronics may be required) CNC Machined Parts High precision High quality surface finish Aesthetically Pleasing Prints almost every material (including PLA ) Short Thermal Transition Improves extrusion accuracy Reduces 'blobbing' Lowers extrusion force Less retraction required Easy Mounting Plenty of community designed mounts (eg Thingiverse) Designed to fit in 16mm Groove Mount (ie J-Head) Version 5 of this HotEnd is more easily assembled and remains directly compatible with standard 16mm extruder bodies and should fit most extruder bodies accordingly

It was originally designed for printing with Boron Carbide (B4C)
