Overall the video has a clear message that has nothing wrong with it, so what I have to say is in no way anything negative, more so a correction. While talking about the heat transfer in mugs you say how vacuum insulation is no better than foam and so forth, while there is truth in the following statement that most heat escapes while being conducted via the steel to the top, the thermos itself would be a notably worse item if using other forms of insulation. As mention in the video, 3D printing is amazing at creating internal geometries: creating sealed of pockets of air, minimal contact structures, this tackles the two most well know forms of heat transfer- convection and conduction. While smaller air pockets are better at fighting convection transfer than large pockets, the simple act of eliminating convection is far better solution. Secondly, any and all material having a direct connection from inside the hot container to the cool outside wall is far worse (thermodynamically speaking) than no connection at all, hence vacuum insulation being prominent for longer lasting storage. Thirdly, the only form of heat transfer that is hard to fight for both manufacturing methods is radiation, but even here you can win some if you make the inside of the chambers as far away from a perfect thermodynamic black body (i.e. less heat absorption). I thank you for spreading the hype for 3d printing and hope that my words will be nothing more than a helpful addition.

I'm a tad bit surprised the cup wasn't designed with the hole the stainless steel sleeve slides into being a grip fin style hole like in you're other video about designing better holes. My thinking is it would reduce contact points between the sleeve and the cup to further insulate the drink. Fewer points of contact with the cup, slower heat conductance. Of course the rim would need to be closed up so the cells between the fins wouldn't be open to the outside air, as well as to prevent your drink from sloshing down into said cells.

My daughter likes to use Voss water bottles, and she re-uses them. They're a fairly heavy glass. After she broke a couple of them, I designed a cozy with a handle. The fit is good, and made better by a TPU ring around the top. I was surprised at how well it insulated the bottle. I was just running cubic infill. I printed it in PLA +, because she isn't using it for hot stuff. I don't print a lot of PETG. I have a hate-hate relationship with it. maybe I'll try one of the CF blends.

I haven’t been able to get a 3D printed liner the thermal properties of a vacuum sealed (with copper radiation insulator) tumbler, not even remotely close. However what I did find that worked really well was using a wal mart “contego” thermos which has a vacuum sealed interior but it’s very thin than printing a cup that goes around it that doesn’t tip as easy, has a handle etc etc. Since very little consideration needs to be taken for insulation it can be fairly thin but have a nice wide base. I also made it so my lips don’t touch the plastic which even if food safe is a gross sensation.

The mostly empty infill isn't as good an insulator as a vacuum flask but most people would actually prefer a mug that keeps hot drinks hot for a work day but don't want it still scalding hot two days later. Sometimes there can be too much of an engineered good thing. Most people want an insulated mug like this that has some ice left at the end of the day. The Amazon link shows a vacuum flask. Nice job capitalizing on the Stanley craze even after the brief wave crested.

You are not correct about the vacuum. Vacuum is more than 4 times better insulation at 0.1 mbar. You also cannot seal the air inside in 3d printed model. That means that additional heat transfer will occur through the micro holes. You argue that there is a heat transfer on the neck where 2 metal cylinders are connected to clove the vacuum chamber. That is correct, but the heat loss there is small, because the area of that part is small. It is not a problem and should not be used as argument in the way you used it. The TPU or any other rubber material is quite bad for the handle imho. I think you have created a new type of product. It is not Stanley, but u can do it cheaper and it is usually enough for the every day cup with some thermal insulation. I would say it is great of what you did. A bit more physics knowledge would help with arguments . :)

Conduction, convection and radiation are what you're trying to optimise with a tumbler, vacuum insulation cannot conduct thermal energy via conduction or convection, hence is the best insulator by far. A stainless insert with a 3D printed surround will make a very average tumbler, efficiency wise.

Do you have any data comparing thermal testing? I was inspired to design my own tumbler off this video and I've noticed that both PETG and TPU have higher conductivities heat than air so in my tests where I used a naked tumbler and tumbler with thin walls, thick walls, big air gaps, infill patterns, didn't matter, the plastic performed about 4% worse each time than the tumbler by itself because it allows the heat to conduct through it better than just leaving the metal tumbler exposed to the air. Sidenote it's not to say these things aren't still amazing it still took 8.5 hours to go from 210° to 120° and almost 36 hours for ice water to go from 34° to 48° in both tumblers so still great insulators but the naked one was slightly better always in my tests.

I value your deep knowledge of 3d printing, but you are completely wrong in your explanation of thermodynamics. Saying that air is "True" insulation while vacuum is not shows a complete ignorance of heat transfer. If air was "true" insulation, houses would not use fiberglass or foam insulation because there are air pockets between the studs. A vacuum thermos is far superior to any one using insulation. You claim that your 3d printed design has no pathways for heat transfer, but every bit of infill that touches the inner and outer walls conducts heat. Air pockets allow heat transfer by convection, conduction and radiation where a vacuum only allows radiation. Your design might keep a drink hot or cold for 30 minutes (maybe), but a vacuum thermos will hold its temperature for many hours.

bro i just made a post about this holy moly dude ... air - does not come close to NO molecules to transfer heat, lack of matter = true insulation, its like the time he said injection molding cant detailed textures, bro hasent seen a texture swatch from a injection molding company or somthing

bro just says crap, and TBH these lies probably create more anger/rage and engagement, he could play that card. but misinforming people is misinforming people, period.

The liner is a double-walled vacuum cup, so it doesn't really matter how good the insulation of the holder is anyway.

@j.f.christ8421 good but foam isn't better than vacuum

How do you go out of stock of an STL file? That makes no sense

3:52 I know that PETG is a really nice material for 3D printing, but demonstrations like these never fail to amaze and amuse me xD Also that one is one of the stiffest TPUs I've ever seen... Which is why I thought it was PETG too, just "shiny". It also really shows the "trust" in the product when the one who made puts actual effort into smacking it. Reminds me of the demolition test of the Fireball vice. That was a show.
