Hello all. Looking to invest in new hot end, and wanted to know if there is any benefit to switching to a 1.75mm hotend from 3mm?
Other than the ability to go with a smaller nozzle, I would say no.
Higher pressures in the nozzle, less gearing to get to the needed pressure, lower likelihood of stripping filament…
1.75 is better. Less pressure, more accurate, less volume per mm, faster melting (yes it makes a difference), easier to work with
The only down side I can see is deviation in diamiter will affect you more .1/1.75 > .1/3
This won’t be an issue with high quality filament.
Now come the question is it worth switching? Thats up to you.
@Moshe_Kashani , @Sebastien_Plante , @Mark_Fuller . Thank you. I am building a new printer and may go with 1.75 hotend. Have any of you ran 1.75 with bowden? Are there any issues vs 3mm.?
I use 1.75mm with bowden, really like the setup !
@Sebastien_Plante That is cool. Def. going to try the 1.75. Thank you everyone.
@John_Santiago I use an e3dv6 1.72 Bowden and its great I don’t see what everyone is afraid of its actually easier, if something goes wrong its easier to find the problem. I was afraid in the beginning because I thought that movement of the tube would push more filament out but that’s not the case. I also just switched to a direct dive mk8 so far I got 1 benchy out and its pretty decent just need to so some more tuning.
If you are planning on doing it you should check out tech2c Chanel on YouTube he has very good videos and parts. You can also check my thingiverse page I have some parts there to.
From what I understand, 3mm will be increasingly difficult to source. So a 1.75mm could be a wiser move in the long run.
Yea. Think I will try bowden setup with e3dv6. @Moshe_Kashani what supplier did you purchase your e3dv6?
Fillastruder for myself, I’m in Canada.
@John_Santiago I got mine from https://www.printedsolid.com/ $98
but there are other distributors for cheaper now like filastruder and makerfarm both of which I’ve purchased from.
@Moshe_Kashani Cool thank you.
