Elegoo Jupiter... 6k 12.8" print volume!

I'm really going to try and get on the initial run of this machine. It's a dream come true, especially with an auto resin feeder...

I’m excited for this, but was hoping for a larger print volume. It seems there is a huge gap between printers like the Jupiter and the Mono X to ones like the Phenom L.

$600 is a pretty good price point. Might get one of those once I use my Mars 2 a little bit more.
Keep in mind that $600 is the early-bird Kickstarter price. Standard retail is $1300.

Not to mention that it doesn’t include S&H.

I’m not saying the price for this printer isn’t good, just want people to be aware of what they can expect to pay vs the early-bird advertised price.

And also a huge price difference... The initial kickstarter price of $600 is unbeatable for this print volume. Even sitting at $1300, it's close to $1200 less than the Phenom L.

Print Volumes:

Elegoo Jupiter --> 277.848*156.06*300mm
Phenom L --> 345.6 X 194.4 X 400 mm

Aslo, 6k screen in the Jupiter versus 4k screen on the Phenom L. I guess it really comes down to if you need to additional print volume to meet specific deadlines/needs. I just want more print volume at an affordable price point to do larger projects.

On another thread, I did calculations on the pixel density of some printers.

Anycubic Photon
The build area X&Y is 115x65mm which is 7475mm squared per layer.
The screen resolution is 2560x1440 which is 386400 pixels.
This means that each square mm gets about 493.2 pixels.

Anycubic Photon Mono X
The build area X&Y is 192x120 which is 23040mm squared per layer.
The screen resolution is 3840x2400 which is 9216000 pixels.
This means that each square mm gets 400 pixels.


The Elegoo Jupiter looks like it has even less of a density.

The build area X&Y is 277x156 which is 43212mm squared per layer.
The screen resolution is 5448 x 3064 which is 16692672 pixels.
This means that each square mm get 386.3 pixels.

I know they talk about pixel pitch and stuff like that, which is just the X build length divided by the X screen resolution, but I don't think the above math lies.

Yeah that's the one I've been thinking of getting. I think quite a few people here have that model and like it.
I got mine about a week and a half ago and I'm loving it so far!

Keep in mind that doubling your pixels per square mm only gives you a 50% increase in linear resolution, which will determine what the minimum feature size you can resolve is. For that reason, I find pixel pitch more useful. It's more complicated than that of course, because of light bleed and exposure impacts on the actual voxel size, but it's a good start. :) Bottom line is you'll get great results on any of these printers and for me it comes down to build volume vs. cost, customer service, and other factors.

Elegoo is listing the pixel pitch as 51um on the Jupiter

Saturn (4K) and Mars 2 Pro (2K) are 50um
Anycubic Photon Mono X (4K) has the same screen as the Saturn, so the same 50um pixel pitch.

Photon Mono is back up at 51um

Mars 3 Ultra (4K) is 35um

If I hadn't already bought a Saturn, I'd be perfectly happy with the resolution on the Jupiter as a trade off for a much larger build volume.

Yeah, I'll take the trade off of size to a little less quality, any day. Plus with the monochrome lcd with the faster cure rate, it's a no-brainer.

But it's good to know the numbers, whether you use pixel pitch or pixel density so as not to expect that just because you can print bigger, it's not necessarily higher resolution. With how technology is progressing, it won't take long to have both size and high resolution at the same time.

Elegoo Helios, then Galaxy?
