43:15 that problem could be fixed by using - Laptop cooling , as in Heat pipes/Heat sink, the copper that uses water convection to draw heat away from the processor ~1000 watts second .

I love this! people never get to see the level of detail that (good) engineers agonize about every little detail. Amazing. This should be required viewing for engineering students

[@emberprototypes]

On my list of things to watch when I get home!

Love all the thought that went into this machine, and would have loved to work on it with the dev team. If I was looking for a quality machine, this would be my choice. Just checked and yeah, it's still way outside my hobbyist budget. But thanks for the teardown video, and sharing the info. Good work.

It was very professional, especially the intelligent and organized presenter. One point that stands out is the temperature of the light produced and its impact on the LCD screen, causing the resin to heat up. This is particularly problematic for large parts where the LCD is fully illuminated, and the resin temperature can rise above 37°C or even 42°C, leading to resin degradation and part failure. In my opinion, the only solution is to use crystal to protect against the heat generated by the LCD, unless you upgrade the LCD technology and use heat-insulating materials. Additionally, you could use a glass LCD protector that is very transparent and easily replaceable to prevent dirt and scratches on it.

I've been looking forward to this today!

Do you think technology will advance to the point where, instead of using high-power LEDs with a frequency of 405 nm, we can have high-resolution LCDs that can produce such a frequency and power on their own, eliminating the need for a separate light source? Spilling resin on the LCD, incorrect penetration, changing resins to different colors, resin hardening in corners and crevices, and difficult cleaning are significant challenges for 3D printer farms. Replacing and maintaining parts with so many screws is very time-consuming, especially since the lifespan of FEP and LCD is short. When the hardened resin suddenly falls into the resin tank, the upper plate presses it onto the LCD because it cannot detect it, causing the LCD to crack or a spot on it to be damaged.

[@markus1000000001]

I have replaced the resin tank for the sixth time, and its sealing has deteriorated and deformed. If the tank structure is cost-effective, allowing for multiple resin tanks and replacing them after 10 or 20 prints, it would be much better.

just made my night

[@alfredanil]

Made my day 😊

[@CandyHam]

yes please lets get a 4L teardown!

Hi there! Is the top yellow microarray inspired by the concept of microarrays used in OLED TVs that were launched in last year CES?

[@jonnyhifi]

Can’t wait ! :) we’ll err yes I do have to wait … lol

[@jonnyhifi]

Superb ! So worth waiting for. It’s a real win win. I can nerd out learning from Shane’s deep insights about design and function, whilst it certainly strengthens my appreciation for the Formlab brand that there is such meticulous effort gone into making this just work. (I have a Form 2 btw - A lovely machine, which obviously was agonised over in turn during its design - yet clearly prehistoric compared to this given you have iterated through successive machines :) ) thank you so much for making this and posting it.

[@Rybek]

Awesome, I hope hobbyists will get something like that in 10 years bellow 1k Euro.

[@Haxzyr]

It looks like young engineering..

[@CorneliuTicu]

A test that would make a great difference is the distribution of material in a round object that is able to rotate at high speed. Could you please post such tests at different dimensions? The bigger the better. Thank you.

Why is he wearing a warm hat?

[@bloodtastesirony]

to maintain optimum cranial operating temperatures

Bad hair day, robot was buggy.
