DescribeRapido hotend has a unque copper alloy cylindrical melting zone wrapped in a high powered ceramic heating element so that it has a more uniform heating section and a shorter heat transfer path Therefore greater flow and heating efficiency can be achieved The thin walled surgical grade stainless steel heat breaker and three titanium screws make the entire structure more robust With the heat sink firmly in place the nozzle can be changed with one hand and the heat breaker will not be easily damaged by collisions during printing The detachable groovvmount adapter allows for dual use of groovv mount and screw mount The rapido hotend has 16mm bolt circle diameter mounting screw hole same as the dragon hotend Pre set nozzle thread depth keeps leaks from happening again The rapido hotend has the same overall dimensions as the Volcano hotend with V6 or compatible nozzles installed by default it can be used as a direct replacement for the Volcano hotend while having a higher flow rate up to 45mm³ s and the same extrusion accuracy than the Volcano When the rapido hotend is fitted with a volcano nozzle and melting zone extender it has a even higher flow rate up to 75mm³ s while maintaining a relatively small size and weight High Heater CapacityHigh power cylindrical ceramic heating element up to 115W24℃ 280℃ less than 51 secondsMore information about Rapido Hotend1 https trianglelab net u file 2111 01 file Rapido hotendcylindricalce
