Good grief, wasn't 3D printing a thing back in 2009 or so?

I use Cathy as a negative indicator.

retail printers only exploded with Bambu

Mold is only one of many methods of metal fabrication. Worked in business for over 30 years. We have had our eye on additive manufacturing for at least 15 years…evaluating the tech to see if it is viable for utilizing. The tech is far away from replacing traditional metal fabrication methods. We do utilize it for prototypes though…but not real world output. The current output is costly per unit and does not accommodate customer metalurgical specifications when tested.

3D printers will become more common as material science catches up

5:13 I know like a half dozen people who do and I've never touched one in my life

she literally proposed Proprietary Enshitification to make more $$

3d priting is good for prototype only

I bet Cathie Woods made plenty of money.

Both Kathy Wood and Wall Street millennial have no clue what they are talking about on this topic. AND the 3 companies he is listing are not the real players in the market. AND he is severely wrong about some methods logistics, for instance the negation of DED and WAAM.
From a technical standpoint I would give this video a 3/10 and say he completely missed the bus.

I'm a materials engineer
I am an avid 3d printing hobbiest and have built almost a dozen 3d printers. I also have experience with metal 3d printing technology.
I think 3d printing will never gain mainstream appeal. It is really useful to makers and engineers, in almost every material type. It is however largely used by the bulk of the community to make wasteful trinkets.

That said it is a revolutionary technology for some engineering applications. Especially, aerospace, nuclear engineering, healthcare and high end automotive. It is also extremely powerful for prototyping and building bespoke project solutions. I have personally used it for research purposes a lot and it is a game changer in a laboratory.

All this to say 3d printing is a revolution in materials science that will be happening for the next 25 years at least. At the same time, it is not for everyone and does not belong in every home, and it isn't going to be resulting in any mega profitable corporations.

Now how will AI make 3d printing better? /s

Your description on how metal is processed isn't correct in that all you are describing is casting, which isn't the comparative thing when looking at cost reductions (although there is less waste in printing a metal part via SLM technologies, which is also not the only metal AM technology, compared to casting). That is compared to machining, which not only reduces waste going with an AM route, uses far less complicated tooling for higher complexity designs. wax solutions to create voids for instance is unnecessary in an AM solution because you can directly print the voids into the shape. This means that you no longer need to form, melt out, braise, etc. those voids together.

If you want to compare casting to metal AM, casting has the limitation of mold design. Not only are molds expensive to make, they are often considered long term consumables unless the mold in question has delicate components within it (channels for fluid passage within the component for instance). Due to the small feature size and required tolerance, this will vastly reduce the mold lifespan. On top of this, casting is even worse than machining for complexity cost penalties. A mold can then easily end up costing as much as the AM machine and several months of operation alone.

Casting also has the issue of needing lots of energy to actually work. You're dealing with liquid metals to be able to cast, and as such, you have to heat up a bunch of metal to high temps. This is a much higher cost than doing localized sintering.

Cathy Wood track record is arguably worse than using a magic 8 ball.😂

I think 3D printing failed to productize the thing properly. They expected everyone to suddenly grow into engineers who understand material strength and how to use CAD. Actually going to the store is easier.

There is something seriously wrong with Cathie Wood
Surely and clearly
Everyone knows she burns dollars to heat her home

The strategy of buying every turd scam company in an immature technology space is not working!

Invoking Tesla does NOT help.
