  1. Nice collection.

    It would be great if you could share some comments about the features of the top 5. Things like price vs reliability vs ability to print 1.75 PLA.

    I am looking forward to buying my next hot-end and I found a lot of information, but it is all over the web.
    It would be nice to have an analysis in a central place.

    I've read things like low quality j-head clones, all metal hot-ends that can't print PLA or that alwasy need a fan blowing at the cold end, etc...

  2. Hi where can I find source files to produce your hot ends in exactly in the original form.

  3. This is an awesome collection of hotends, I too would love a bit of info about your personal experience with some of these, I have been using a ubis hotend which seems to be pretty good, although there is lifting issues coming up as it goes around a corner a particular way on the first layer, I fixed this with hairspray (I am only printing in PLA), but it started doing this after about 3 months of punishment. I'd rather support a fully opensource hotend :)

  4. I haven't, personally, used these hot-ends as I mainly collect them and read what comments others have posted regarding others experiences. From others' experiences, the best PLA hot-ends have a PTFE liner.

  5. good post! I think may be the article about nozzles at can help you a lot!
