UPDATE: Just so you're aware, some of this information is out-of-date. Keep in mind, I made this video over a year ago, and was only a couple months into 3D printing in general. It's just a generalized opinion and shouldn't be taken as serious advice.

I've learned a LOT since January of 2023, so I'll be posting an update with my current thoughts on the subject (I now use an all-metal heat-break, but NOT the "bi-metal" variety).

It's still a fun video and I had a lot of fun making it, with the animations etc...

---

This video should apply to most 3D printers, especially the E3D V6 and similar hot-ends -- any style where you have a choice between an All Metal (or Bi-Metal) and PTFE-lined heat break. Stick to the end for an issue specific to the Bi-Metal version that cost me time and money, and almost ruined Christmas!

This is also partly a follow-up to my video, where I created (and shared!) an adaptor, allowing the installation of a V6-style hot-end on the Monoprice MP10 aka Malyan MA10 3D Printer.

But it is mostly general observations I've made using the "all metal" and "bi-metal" heat breaks. I kept getting jams, and through the process of elimination, I found myself going back to a standard PTFE-lined heat break.

Watch the full video for all of the details as to why this may be a better choice in some (if not most) circumstances.

All animations and 3D graphics were created using OpenSCAD - I use it to create all of my STL models, and recently discovered that it's quite nice for just creating animations and models to use in videos. Let me know what you think of this style in the comments!

(I'm thinking of actually printing an over-sized V6 hot-end assembly cross-section... I think I have all the right colors on hand... might make for a nice prop, like the things you find in a doctor's office 😅)
