Yeah in the dental applications they deal with the topic almost like it's magic, starting off with a scaled up version of the final part, and then sintering it down under intense heat to get a pure ceramic result at a much smaller size:
...and that is being mindful that these sorts of private practices have crazy funding research! But we might get access to this stuff before we enjoy flying cars, which is nice.
It's super interesting because they seem to have fast results too.
I think a lot depends on how extreme the application is since ceramics are often used for very extreme environments. Perhaps the composition affects the process too? Dental ceramics are zirconia based IIRC. I'm not sure how the print process would differ from that compared to say, alumina though.
This is what I was recently told about the process
"3D printing is in the R&D stage but it is difficult to control the dimensions to fine tolerance; we often see defects in the product composition, with a large possibility to create a pore/space between layers, which is not reliable as a ceramic."
Even for high convection, wood and temp needed aren't really compatible, except for the handle. Even firerpoof..
It would be a convection heater, I just mean that the way logs are assembled is sort of based on low conductivity metals which works well since they don't transfer much heat to the wood, and trying to do that with a very high conductivity ceramic would take some tinkering.
PID have a long way to progress, aesteticaly. That's where i want wood.
The other day I was thinking colored ceramic PID cases might be kind of cool ........
I wanted to do some ceramic 3D printing but the minimum tolerances are too high for most of the stuff I would do, but I figured PID cases might be kinda cool. Always thought exotic wood PID cases would do well too, wish I still had a workshop to use!!
IH just can heat metal, so it won't gonna give anything more than what u get with all the titanium desktop. Or bring them back to conduction..
except for a vapcap, there is no really interest in, as desktop.
That's true that my induction concept would be based in metal as I do think it's neccesary for best performance with induction (less thermal resistance). What it would potentially offer that the other desktops don't is the ability to use on demand, free of any cords and cables. To be able to pull the water pipe out, load a bowl, and inhale while heating without any waiting would be ideal. Plus I think the manufacturability is good with my design as it could be likely made without any machining. But I would need to work with someone on a custom induction heater for it to really be anything special, and that's wayyyyyyy out of my wheelhouse! Cool idea, probably not the right time for it though.
But IDK.
I have so much fun *buzzing*
between stuff, though I do feel close!!
Rolling the dice, here's my
DABBED &
CAD idea for the night, based on various old sketches and doodles from 2020.
16MM CNC Machined borosilicate glass housing, heated by a path isolated & recessed cartridge heater.
Air is distributed through the 8 airways for heating, then passes over a 12mm glass bowl (14mm joint)
Ideally a
handle would thread in to this glass housing to make it handlable,
sort of like a desktop G43, sans beads. I didn't feel like drawing it in tonight, but I think this would be quite cool.
A true "injection" heater, nominal dose friendly, no exposed coils,
all glass.
Ceramic, i like where it is (u're) going
