This is the new, awesome and huge resin 3D printer from ELEGOO, the Saturn 2.
It has a massive 8K screen, very sturdy build with metal parts, tempered glass protection
for the screen, very fast printing time, air filter and some other features.
In this video we will see what you receive, prepare the printer for printing, we make
some tests and even place the printed objects under the microscope.
In this way you get an idea about this product in case you want to buy it.
So guys, let’s get started.
What’s up my friends, welcome back.
I’ve just received the new resin printer from ELEGOO, and as you can see, the box is
huge.
This is the new SATURN 2 printer which is 8K and has a very big printing volume so let’s
check it out, and we start with a quick unbox.
As you can see the printer is well secured so it cannot be damaged during shipping.
Then when we take it out we get the box for the power cable and inside the printer we
have the tool box and the printing bed, and sincerely, this printer is really big.
Let’s check the toolbox.
Well inside we get dome resin filters, some gloves and protective masks, the power supply
of 24V, pliers, a plastic and a metal print removal tool.
A pen drive, some tools and spare screws, the user manual and this interesting part
which is an air filter to remove the smell and bad vapor from the resin.
That’s pretty much all you receive with this printer.
We are ready for some tests.
I take the film protector from the printing bed but also from the resin vat.
Put back the vat and let’s home the machine.
Connect power to the printer and use the main switch to turn it on.
Go to the menu and lift the Z axis.
Then place the printing bed over and tight the top knob.
Use the allen key to loose the screws holding the bed.
Make sure it can move freely and then go to the menu and click the home button.
The machine will go to the 0 position.
At this point tight back those screws.
Then you have to go in the menu and hit the set Z equal to 0 button and not the machine
is calibrated.
Move the axis upwards once again.
I also connect the air filter on the USB connector.
Let’s add some resin.
I think I should shake the bottle a little bit more next time.
Now insert the pen drive into the side USB connector.
Go in the menu to print and select the first example file.
And now is printing.
Till we get the results let’s talk a bit about this new printer and all its specs.
This printer is impressive.
Obviously, the part that calls our attention is the 8k resolution display.
Now that resolution is actually 7680 by 4320 pixels and that results in perfect details.
Actually, I can’t really see any layer line in the results at 0.05mm layer height, totally
perfect details.
Now the printing area is of 219 by 123 mm, so more than 26.000 mm squared so with a resolution
of 8K that equals to more than 1000 pixels per mm squared and the pixel size of 28 microns.
The height is also big at 250mm so you can get pretty tall prints on this machine.
The display is monochrome so the exposure time can be very low from 1 to 3 seconds so
you can finish your prints quite fast.
We have the power plug on the back just in the middle of the printer and you also have
this back lid that you could take out and access the main board if you want.
And as I’ve shown you before, they now included this USB powered air purifier to lower the
fumes from the resin.
Now have in mind this USB connector is strictly for the air purifier and can’t be used for
something else.
The air purifier is filled with carbon so it will filter some of the fumes.
Also, the plastic cover has a fume extractor hole on the back.
You can remove this and connect a tube for an external extractor if you have one.
The machine is using two metal linear rails so the movement will be smooth resulting into
better prints.
And about the screen, there is something more that I like.
It now has a screen protection because the screen might get very fragile.
That’s such a nice feature and the protection is a 9H tempered glass, just like those you
use to protect your smartphone.
This is a great feature because imagine you drop your vat or something else on the screen
and you break it.
That’s quite expensive.
It will also protect against resin spill and is easier to clean.
They have a new light system with a fresnel lens.
Basically they have a powerful UV light and to distribute the light evenly they use a
fresnel lens like this one and make sure the light will reach the entire area of the display
evenly.
The vat is made out of metal and what I like is that it has these screws below so when
you put it on the table it makes sure that the FEP film won’t touch the table.
That’s alsos nice and when you place it on the printer, it uses those same screws
and these holes to center itself on the screen.
Then all we have to do is to add these screws and tighten them.
I also like the new printing bed, especially the locking knob.
Is a lot bigger and very easy to use, very sturdy, made out of metal and maybe a bit
heavy, but I like it.
And the nice thing is that you can use it as a support and place the bed upside down.
The pen drive is inserted on the side, the power button is in the middle and then we
have a color touchscreen to control the printer, move the axis, start exposure, change some
settings and print from the USB drive.
The design is cool, the case is basically all metal and it looks pretty nice, right?
By the way, it is quite silent.
You can’t really hear anything when the motor is moving but all you can hear is the
fan inside but even that is not loud at all.
Ok now let’s see some results.
The first test was obviously with the Elegoo towers that you can find on the USB drive.
I’ve made a mistake of not shaking the resin bottle too much but anyway.
The prints turn out great.
Once you clean them with some alcohol you can then use a UV flashlight or let them under
direct sun for a few minutes.
In that way they get stronger.
This was actually not a great example because I haven’t cleaned them too well with alcohol,
let’s just skip to the next one.
I sometimes play league of legends so the next print was Jinx.
This time I had to generate supports because this object has a lot of hanging parts.
To generate the printing files I use Chitubox which is included on the USB drive.
In options select the Saturn 2 printer.
Then drag your object and add supports if needed.
Click slice and once it is ready, save the file to the USB drive.
Insert it into the printer and click print from the screen.
This print took a few hours and we can see the object going up and down, layer by layer.
When the print is ready, use the print removal tool and get it out from the printing bed.
Then we clean it with some alcohol.
Then I leave it under UV light or direct sun.
I have to say, it looks pretty promising.
Now we have to remove the supports using some small pliers and our hands.
And there you have it.
I still have to remove some small parts from the supports but the quality is amazing.
We can see very small details and you can’t see any line from the layer change.
It really looks like a mold injected part actually.
Here we can see it under a macro lens.
And once again, the details are prefect.
On the head we can see some lines so I thought it would be interesting to place it under
my microscope.
So I let you decide if this is good quality or not.
By the way, once the print was finished you can cover the printer to protect the resin
or use the filters and store back the resin into its bottle.
Next print was with some black resin.
I wanted to test the entire area of the printer so I’ve placed a few prints all around.
I have Ashe from league of legends, an elf, a horse from a chess game, these parts I need
for a future project and this tiny tiny test cube.
The printer took around 5 hours.
Once finished, again we clean them with alcohol.
Then we cure them and let’s take a look.
We start with Ashe which once again has supports and we have to remove them.
Ok so becasue this was printed with balck resin, we can’t see the details that good
but close enough it looks once again like mold injected plastic.
Since the color is so dark it also looks a bit dirty.
On the cape we can see some layering.
But have in mind that this part is less than 1mm thick and it was printed with not too
much support so I guess it moved a lot.
But the arrow and bow are quite good even if they are so thin and fragile.
Once again a good print and there are just a few spots where we can see some layering
effect.
But in overall it looks just as a mold injected part, very smooth.
Next let’s take a look at this very small cube.
Have in mind this is just 1 cm.
We can see some details but I think is better to place this print under the microscope,
right?
This time since we have so much zoom we can see some layering.
But look at these small details.
Have in mind these parts go from 0.1mm.
We can see that the 0.1mm slot is kind of closed but above that we have a clear slot.
On this other side we have some nice detail, especially this hole here.
On the other side we have 0.1mm walls and they turned out perfect.
That’s great.
And on this side, the part I most like is this X.
Have in mind this is very very small.
On the top part we can see a bit got broken while cleaning the part I guess.
But what do you think, is this good or what?
On the next print, which is this elf I used another type of alcohol and it did a terrible
job.
The print is full of blobs of dissolved resin that can’t get cured anymore and it looks
like paint.
In general, it was a good print but it now looks very dirty.
So I should use better alcohol and better cleaning method next time.
The same happened with this chess piece.
You can see that the print is very good but the part is very sticky and dirty now.
It has these blobs of resin and is very sticky.
And the last part with this resin was this here.
I need this for a future project and it turned out great.
I can work on my small projects with this printer and create more stuff with small details.
Ok and the next and final print was with transparent ABS.
I wanted to print this Millennial Falcon.
For this part is difficult to see because is transparent but it turned out great.
So many details.
And this print is quite big and took me a few hours.
So guys these were the prints I’ve made so far.
I will make more for sure and I will post the results on electronoobs.com with high
quality pictures.
I hope you now have a general idea about this printer in case you want to order one.

Thanks again and see you later guys.
