IRL antialiasing, who'd a thunk it

I worked for a Traffic Management Center that used DLPs in their video wall because they didn't burn in as much as LCD or plasma showing the same intersection for hours and could be had with almost invisible bezel. They also avoided the cooling problems of plasma at that scale.

Sam Zeloof even used a DLP project to expose photoresist to make homage silicon chips, so if it’s detailed enough for that, it makes sense that it could be used to make 3D printers more detailed

Watching the DLP 'home version' come to market has been exciting to say the least. If you take away nothing else from this video but are into resin printing, DLP defeats having to change the LCD screen for several years; you'll likely be replacing other major components before the DLP module. Just wish the Anycubic version was a bit larger, but all good things come to those who wait. And wait, and wait...

Yeah, really wishing for a larger one. I'm currently looking at getting into resin 3D printers, and would like something in the ~20 cm range, like the Saturn 2, but a DLP would be massively preferable overall. Even if it cost like a 1000€ or slightly over, that'd be basically 5 LCD swaps vs. the Saturn 2, and the DLP supposedly lasts 10x. I think simply because of the size I'm gonna have to go with an LCD printer (it's not like they're BAD), but DLP as a technology makes immense amounts of sense.

@sethstewart1103

Жыл бұрын

Actually, I have seen that good things come to those who build them.

Its also a lot to do with the fact that you are using a lens to focus the projected image. In LCD printers.. the image is sharp at the level of the LCD.. but the actual printing happens further away from it so the projection has already softened a bit. But this also requires a lot from the optics... as its really hard to design lenses that has zero distortion and equal resolution across the field. Though designing the lens for single wavelength really helps.

One of the best explanations and demonstrations about DLP, seriously good work Zack!!

Every one of your videos is so much fun to watch!

DLP truly is magical. I recently bought my first DLP projector and laser based autofocus and automatic keystoning is SO friggin' cool. I can't wait for DLP printers to become affordable! Also yes, I recall the rainbow years. Everyone said I was crazy until I finally figured it out.

This video was soooooo good. I know your a maker but I’d love to see more videos of you explaining how the world around you works. Great video!!!

Absolutely brilliant. it brought back a memory from many years ago, a school physics project making an LCD display, stannous chloride was heated and blown over the glass to make it conductive, if I remember correctly it was published in a practical electronics mag.

It's so pleasing. The setuping and mastering softs amazing.

I've been using a couple open DLP printers at work for a few years now, so I've been able to get any resin and make a profile for it, so so much faster printing than the old form 2 Edit: I work in dental, all of my models are fingerprint surfaced looking voxels lol,

That print quality is amazing. But I don't expect to see much more innovation in the hobby DLP resin printers anytime soon, aside from dropping prices.

Beautiful video explaining the difference in technologies, and introducing me to this beautiful innovation for resign printing. And like that I’ve found the point where I want to finally, finally jump into resin printing. Over 2 years of just straight printing before the sensor is expected to fail? Perfection.
