Now we are talking some seriously sexy heaters. I just got a newsletter from some electronics source mentioning these and I thought I’d share the info.
The ceramic ones have integrated thermocouples and a ramp up rate up to 150°C/s. Nice…
I’m trying to find some kind of indication of prices. Judging by the look and specifications they might just cost you your first born.
@Sanjay_Mortimer@Joshua_Rowley These look like something you might try to build into an advance hotend ! Built in thermocouple and one looks sized to fit around a nozzle … Could be a really short melt zone.
It’s been a while for me since I purchased heaters.
They have a whole series of products specifically designed for injection molding nozzles that’d be usable for hot-ends.
I’m leaning towards their Mini K-ring or wound-coil heaters.
@William_Frick yeah. I’m just brainstorming here but I’m thinking a ceramic ring heater with internal thermocouple around the filament path very close to the nozzle, small heating block for hysteresis if needed at all, water cooling through copper tubing coil around the heat break. Could be a pretty compact package if it worked.
Low thermal mass … multiple extruders … less ooze when doing mixed material prints. Could be the next big advance as materials were news last year, better ways to use them this year.
Watlow makes most of the heaters, TC’s, and temperature controllers for the equipment I work with. Their stuff is VERY high quality, to the point that I can’t recall a failure of their parts in the three years I’ve been working with them… Unfortunately they aren’t in my price range for hobby stuff.
