Ring heater block

Hi all,

just want to ask you if anybody know where to buy ring heater for hotend like the one used for example on Mini Hotend from Deltaprint or another one . Do you have any experiences with such heaters or would you know where to get them?

Any advice will be appreciated.

Thank you in advance.

those are metal ceramic heaters. you can get similar ones from [www.aliexpress.com]

i personally thinks its a better design BUT is very fragile so you have to be careful with wire management.

the main reason i find it better is how quickly these things can change temperature. it can reach 240c in 30 seconds. its perfect for dual extrusion were you might wanna turn on and off a nozzle quickly.
