The king 😮great work

Absolute legend! Please keep going!

YOU WHAAATT!!!!?????

I'm 2.75 minutes in and I'm blown away by your confidence to design your own fuggin camera for your own laser welder. So smart, man

Dude, you are awesome! Tenacious. I want to help message me. I have very sophisticated 3-D sla printing abilities. I can print down to 10 µm. I also worked heavily with AI and also have the hardware to run simulations quickly and run AI quickly on my own systems.😊

hats off to you sir ,testament of what a man with will is capable of.

this is some great work! thanks for sharing it with the world!

I'm absolutely certain that even half of this project would've driven me to insanity. The world wouldn't have half the tech it does without people like you.

"Herb" grinder :D

I didn't understand 95% of what you are doing, but I can easily tell that you should be respected for your knowledge and dedication... I only know about normal 3d printing (pla, abs, nylon and CF etc.) and I call myself a maker... But compared to you, I am a teletubbie..

do you recover the argon at all?

honey wake up! Metal Matters is revolutionizing the world as we know it

I’ve… been waiting for this..!

Fyi, your 40-80 spine for your Nd:YAG laser is a little better than a wet noodle. The most stable lasers (of that size) that I've worked with milled a pocket for the cavity out of a 6" (150mm) block of solid aluminum. I'd personally stay with the Nd:YAG vs a fiber laser. These lasers are very durable and the large beam means it can survive 10's of Kw peak power during reflections or Q-switching. Also, I bet you're better off with a multi-mode beam. I'd bet a "top-hat" or "donut" beam profile would work best.

MAKE THE IRON DONG -- CYPHERPUNKS FREEDOM SYMBOL

Amazing work

This is so very kiwi, a very very clever kiwi, but clearly a kiwi, nonetheless. I have a personal question for you, how many generations of kiwi are you? My great grandfather was a POHM but his WW1 widow was an ex-Auckland kiwi and I'm not sure how far back before her it went. Great work and superbly narrated and edited. I look forward to the next one. I would offer help but it's clear to me that I not only wouldn't be help, but would also just slow you down. Keep up the great work. <3

Holy fuck man what an incredible achievement - I'm not sure if the result or the ironclad perserverance is more impressive

80% was too complicated for me.

SISU. Sheer tenacious perseverance.

An incredible amount of work for one pair of hands! Worthy of admiration!

Holy shit, this epic story has more drama, grit, heroic refusal of defeat and plot twists than the average HBO series! I absoultely salute you for the mental fortitude to not give up. o7

A job well done mate. Insane professional engineering for the money given. You've got some serious knowledge of optics and SLM printing. I've graduated my bachelors on experimenting with SLM printers, the second time I made a laser positioning system for my masters. The struggles I see in your video feels like a 10 of my project all cammed into one project. My respect! I hope you'll will have a lot more succes with these projects!

oh man, this is freaking awesome, will work with aluminum ?

Try throwing a welding lens over it?

You are awesome dude!

My little fly brain has exploded with too much information.

I keep wondering how difficult it would be to try this in a vacuum chamber. Could you keep the powder from gumming up and fusing to itself in a vacuum chamber? Given that you're using ferromagnetic metals, could you suspend particles in a vacuum using magnetic constriction? Might be an interesting thing to experiment with if you could keep powder suspended in a loop in a vacuum and use a laser to pulse it onto a surface. Perhaps calibrating the laser frequency to a multiple of the atomic vibrational frequency of the metal you're working with. Or how they managed to bring the temperature of rubidium close to absolute zero by using the inverse frequency. Probably a dumb thought, but who knows.

Make it a kit! Kickstarter!

This is a story of a stranger who I shall never meet, yet hold the deepest respect for.

times like these that you wish that you could give more than one like. This is so cool, and immensely well done!

Please dont shell out to the companies most likely waiting to buy you out or to "hire you" to take down your publications The 3d printing market is really sneaky in these areas

Extremely impressive! I've worked at two companies doing hardware engineering on LPBF machines. I can appreciate the complexity of what you are doing and cant believe you got this thing to print a benchy on the budget you are working with.

Were do you live in Australia

excellent work! hope this starts the DIY metal printing revolution!!

if you had flux on the wire, you could direct all energy on the flux. also k.i.s.s., complex systems by design are hard to implement. there is a more optimal solution to achieve the things you are now doing in a more complex way. namely SLS/SLM using the current implementation methods. copy is only a copy, not original.

NO WAY i just watched a few of your videos and thought well this is a really great high quality interesting content and was so sad seeing no uploads for over a year and now you come out with this banger. Keep it up amazing work.

We've been waiting! Glad to see you back

lol that's a lot of argon. But mega props for doing this. very badass.

'So I decided to do something challenging'... You gonna bring back the Buran program next? What an insane level of dedication man, I can't believe you never ragechucked that thing out the door. Thank you very much for putting your research out there, I'm sure this will become an iconic reference for the community. I feel inspired after this. I'm about to go beat the ever loving ---- out of a machine at a factory (that apparently manufactures frustration) and to be honest I was kind of dreading the work. Seeing you **hammer** through this gives me some motivation. I liked your weld idea, that was cool! You really answered some questions for me on why messing with powder is worthwhile, I'd say so for the reasons demonstrated with leveling and such. At least you have the spare parts lying around to build your country a laser missile defense system :D I hope you earn your money back soon.

Just brilliant! I too have spent many hours trying to film welding, your camera following the puddle was just wonderful. Bravo. Very interesting.

Are you familiar with the two industrial camera HDR welding glasses from over 10 years ago?

This guy is making youtube videos for 2124 not 2024.

How tf can you afford this

Huge work there thanks to share all of this with us 🙌

Just, wow.

I understood about 20% of the video, language barier and all but still this is over my pay grade :) I have no idea why I watched it fully but.. here we are. Thanks for the lecture :)

Superbe travail .....GROS GROS respect , je suis admiratif 👍👌👍

I understood some of those words

Me casually listening to mad scientist while driving, congrats
