When you ask for an engineering interview and they give you the marketing guy

For those who didn't get it - Hardware, software and chemistry that allows us to control light and oxygen !!!

This guy is really good at not answering questions. I know just as much about this printer as I did before I knew it existed.

4 year old me: "Dad, how do people see and breathe?" Dad: "Ok, so there's this new method of using light and oxygen..."

Q: How does it work ? A: Light and oxygen ! Q: How long will it take to print an object ? A: Light and oxygen ! Q: Ok but.. A: Light and oxygen, mah dude ! Q: Are you okay ? A: Light and oxygen ! Q: What time is it ? A: Light and oxygen !

Hmm yes, light, oxygen and molecular chemistry... Now tell us about that well it uses light, oxygen and molecular chemistry...

Tested: How do you make this stuff work? PR guy: We hire smart people.

13:47 "This is mind blowing for people..." -> 14:03 (not so distant gunshot)

I wonder if there is a marketing industry award for saying I don't know the most different ways, without people real good that's what you said.

Let me tell you about this really amazing thing, and how good it is, and that it's better than anything else, and how really smart people are doing some pretty amazing science, but its also really complicated, so I'm not going to tell you how it works, but trust me because it's the future... Basically sums up this video.

"Hey, Kirk, tell me about that light and oxygen!" "Right!"

Im glad they used great engineers and great technology and amazing chemistry.

When I'm 90 and I have a bunch of grand kids, I'll tell them about the first 3D printer. And they'll be like, "Grandma you scrub ass, I can 3D print in 3 seconds from the back of my smart hologram phone! Watch me print out a real hover board."

So you're saying it's oxygen AND light needed to make these great parts?!? Wow, glad you said it 3,472,379 times!

I have a question; are light and oxygen used in any way inside this machine?

15:00 “I love that you’re so informed on the chemistry side” - then proceeds to bullshit about nothing instead of answering his intellectual question.

If you listen closely at 14:03, you can hear the sound of someone in the office blowing his brains out. Immediately prior, he had fallen into the realm of oblivion, beset by a total knowledge of all reality, and the torrent of corporate-lingo-infused tech jargon at that moment had become the camel which broke his straw's back. eerie how they didn't edit that out.

Sooo... are you controling light together with oxygen? I missed that part... 37 times...

As far as I can tell, the purpose of the Oxygen is simply to prevent curing of the resin actually on the transparent plate at the bottom, thus avoiding the need for the 'peel' process and (kind of) making it a continuous process. The transparent plate at the bottom is presumably made of oxygen permeable glass/plastic similar to that used for contact lenses.

Owner: someone’s coming to do an interview Employee: ok hat should I tell him? Owner: light and oxygen

i wonder if he talked about light and oxygen... i don't remember

7/10 too much light and oxygen -IGN

Light and oxygen light and oxygen light and oxygen light and oxygen light and oh yeah oxygen.

The control of oxygen is done by using a micromirror chip which creates the light pattern required to print the shape you want. They were originally used in projectors for computers, It's made up of a lot of tiny mirrors each around 8 microns squared. The UV light hits the micromirror and creates a pattern, silicone is used between the resin and the light as it allows oxygen into the resin as it is highly permeable to gas. All the while the UV light prints it layer by layer. That's how they manage OXYGEN.

Have they tried to balance the light with oxygen to make amazing parts?

This video could have been 5 minutes long but they kept on repeating the same things

When can I buy one? Light and oxygen. How do you actually control the oxygen? Hardware software and chemistry. What kind of hardware? We live in an intersection on chemistry, hardware, software, light, and oxygen. This frees you to do what you want to do, because of oxygen hardware engineering, and engineering, AND light. Set the shape with light and oxygen. Good talk. Light and oxygen.

"Do you really know what you're talking about or are you just regurgitating bullet-points?" *"LIGHT AND OXYGEN"*

So... it's using darkness and CO2?

NOW! Make me a working calculator out of chocolate!!!!

Sounds like someone at 14:03 was done with light and oxygen.

It's kinda sad that Kirk's confusion at Norm's knowledge is understandable... a tech journalist that knows tech? Madness!

Whenever the patents expire, you'll see this technology get insanely cheaper. There's a consumer product right there.

Wait, so its controlling light AND oxygen???

6:43 "We hired some amazing engineers" Me looking in the background: i guess some engineers can't afford chairs

absoultely amazing interview. Norm is really getting better and better at this congrats

"How do you get even distribution of gas?" "Alright, so the answer is great engineering"

I started studying radiosity and SLS about ten years ago! The world has changed and it's very impressive! Thanks! Thumbs up!

i think their technique might involve light and oxygen..

Anyone else playing buzzword bingo? This guy is making it too easy.

We live at the intersection of marketing bullet point a, marketing bullet point b, and marketing bullet point c

the hardware, the software and the chemistry; controlling the interaction of the UV light and Oxygen etc

Bind the oxygen into your base resin, add a catalyst that will react with the oxygen under UV excitation, and have the UV projection wavelength and modulation matched so that it excites the catalyst, make it extract the oxygen from the resin, letting it harden. It's pretty genius, where as traditional printers avoid oxygen at all costs, this process distributes the oxygen evenly through the base resin and uses the light to get rid of it only where you need the resin to set. This will only get better as more sensitive resins and catalysts get developed, that need less light exposure to set, letting you pull the shape out faster.

He forgot talk about how they live at the intersection of hardware, software & molecular science.

He was really trying to push on how it was done and made.

How did you solve the problem? We hired some amazing engineers!

Wait what happens with the light and oxygen? I didn't quite catch it

For those who forgot: LIGHT AND OXYGEN!

"so how do you keep the entire build area sufficiently in focus?" "that's a great question. our great engineers use light and oxygen to come up with this bullshit pre-approved, rehearsed talking point sheet."

but isnt it still layering? the layers are just so small that you can see them

8:55 "I can't get into the details of how we control it" Ahh, yup. Alien technology!

We love Carbon. Using many of their machines for custom parts and prototyping.

This is actually one of the first technologies that genuinely made me excited.

These guys are so good they printed a robot and used it to answer questions in this interview!

To sum up: Light and oxygen. Techy projector. Chemistry, software, hardware. Fast parts. You're welcome.

Pretty impressive. There might be hope for the future after all. By the way, does this use light and oxygen to speed up the print?

This is awesome... can't say how it works.. Blah blah blah, light and oxygen! blah blah blah, chemistry!

So does this technology harness both light AND oxygen?

My home is CRAMMED with light and oxygen. I have to assume that any 3D printing I do here will be hella quick.

I like the part where he said right

After watching this I did a relatively quick search among specific sources and can confidently say that I very strongly suspect how they control the oxygen integration and reaction with these printers. The weight versus geometry issues I imagine that are also inherent with these printers can be relatively easily overcome by the application of equal density liquid buoyancy support.

That's pretty cool. I wonder if they're figured out how to use light and oxygen yet? That has always seemed like a big technological milestone.

Great job Norm, you did your homework and asked some great questions.

Please stop saying: *Light and oxygen.....*

this guy really likes light and oxygen

So this guy has basically just taken a sheet of marketing blurb and creativelyt rephrased the same info about 50 times. Well, got to admire his patience I suppose. I have my suspicions about the oxygen though. My guess is that there is a component in the resin that reacts differently when it's heated, so the projector combines UV light that sets the shape, and IR light that regulates the release of oxygen within the compound. I might be wrong on the specifics there, as I'm not an engineer or a chemist, but oxygen release would need to be controlled in a way that was just as fast and versatile as the hardening stimulus, so heat sounds most likely to me, as it can be projected in complex shapes just like UV. That, or fast-moving lasers or ultrasound, but that seems less likely as I imagine it requires a lot more precise engineering for a slower result. Interesting stuff, anyway.

I have an idea how it works. They are using a specail rasin, which i think is hardening under uv-light but is reseasing oxigen under a different section of the light spectre. They also used a kind of a 2 component rasin as you see, so they must seperate it otherwhise there would be a chemical reaktion. So i think the fast printing time is caused by this chemical reaktion, which is supported by the Uv-light to harden the rasin and is stoped by the "other light" beacause its releasing oxigen. sorry for my englisch im german...

The UV light causes a photopolymerization of the resin which builds a chain of polymers to create a physical object and then the oxygen is introduced to the system through a semipermeable oxygen layer which inhibits or stops the resin to cure or harden near that layer. Basically the light hardens and the oxygen is used to make sure the object doesnt stick to the bottom of the window in the resin pan. And then stuck in a oven afterwards to harden.

I'm *thoroughly* impressed with the salespitch this two-face presented despite all the marketing cliches.

Oh and Norm, you're too good for this channel haha. You put other video media journos to shame.

Wish they'd had an engineer give you the tour instead of a salesman.

With the top of the range production printers, inconel printing and such, the chamber is sealed and a non reactive gas such as argon is put in the chamber. By keeping the chamber open you allow oxegen in. Heat and oxegen create gas which creates bubbles of air that prevent bonding. What they do here is control the heat of the laser to control the amount of gas the oxegen gives off, bonding the resin only where they want it to.

When you've been waiting all day to tell someone that your car door handle broke

so basically this is the opposite of the hydraulic press

Wow! So fast! I had to play the video in slow motion to not miss what happened.

Wait! It is using light AND oxygen??? I'm so confused. Please, can anyone tell me?

Hey guys did you know it uses light,oxygen and molecular chemistry

But can it print a duplicate of itself to duplicate itself to speed up prototyping?

Nice, can it also print high temp plastics? If it can then this is one amazing invention!

Me: Yo i might buy one Carbon: Yea just 40,000 and 10,000$ installation fee Me: But its just light and oxygen?

that guy awnsers questions like a pr person would :(

He sounds very passionate about what his team has produced, which is understandable imagine in 20 years time or so when this print could be done within just a few seconds. I know there's the issue of having gravity push the resin into the opening, but with enough pressure you can force fill the resin under the new print as its extruded. This is why there was such talk of heat and pressure.

Does anyone here know if they use a combination of light and oxygen? I can't seem to find anything on the topic.

Looks like there may have been some old resin in the tray when they printed this guys neck.

I liked the part when he said light and oxygen.

When you try too hard to not reveal company secrets: "How does it work?".... "Light and Oxygen."

I've not noticed until now that Norm moves his mouth during the box people intro when the title comes down. It's like he does the swish sound with his mouth.

So, you need to replace that whole "cartridge" each print? Jesus, as if the machine itself wasn't already expensive, you gotta buy those too? I mean, from carbon's standpoint, that's great. But from an end user, that's nuts.

Dont forget kids: Light AND Oxygen!

8:05 i guess one of their (future) partners is Shimano. This pedal looks 100% like a Shimano Saint pedal

Light and oxygen guys, light and oxygen. Oh and we can't forget the physics and chemistry.

Television grade editing what has youtube become, I don't even whatch TV for like 2 years now

Physics, chemistry, light, oxygen. This guy is the prototypical PowerPoint guru.

Repeat after me: 1) Light and Oxygen 2) CLIP 3) light AND oxygen 4) Fortune 50 5) Materials 6) light and oxygen 7) chemistry Congratulations, you are now qualified to be the CEO, or the referee of a new drinking game.

Watch it slow down when the print something that has a higher fill volumer. While this oxygen-inhibition is nice, it doesn't address the need for fresh resin to flow back in to replenish the locally-depleted material at the site of the curing. Notice how all Carbon's speed demos are using prints that are mostly empty space (just thin cured meshes). Sure this is an improvement, but it's over-hyped and there are other fast resin technologies in the works that are not getting the same coverage.

Video summary : "It's complex"

He repeats himself a lot.

I think the secret is light and oxygen

Some advanced printing! I've never seen anything like it! You can even stretch the model! That is god damn cool!
