Very impressive work.

Thanks guys! The new printer is astounding in both it's resolution and producing parts without any failures. And of course, the paint's barely dry on this one and Elegoo is now marketing the Saturn 4 Ultra 16k. Mine has a 12k LCD screen, so the new one has a 30% resolution. I don't know what that means, but in the case of the my Saturn, the increase from 4k in my Mars 3 to 12k in the Saturn has made a huge difference in apparent performance. I used "apparent" becuase of the increase area of the larger build plate decreases the absolute increase in pixels per unit area, Regardless, it is a higher resolution machine. Since the new Saturn model has the same size build plate, it's pixel pre unit area is increased proportionately.

I'm producing one to two runs per day. Today, I cleaned up the full reduction gear sets and started printing the HP turbine in all its entirety. It will be done at 6:30 p.m. so I'll know if its a good print tonight. I've come to expect that all the prints are going to be good. I only had a single failure since I got this machine, and that was very early on. The more accurate exposure time and the resolution making much higher strength parts enables me to use medium supports throughout the part except for the starting surfaces at the build plate. This makes support removal much easier since the medium (and fine) supports pull off by hand and leave no nibs behind.

To give you all a reference of just how massive a 53, 000 hp gear box is, here's the bull gear with a scale person next to it.

The Gear sets are really nice. I knew in the drawing that one set was not in direct, tight contact with the input pinion and suspected that when supports were removed, it would be a separate part. It is! Not a problem since it will settle into it's bearing mounts and will look fine. Here's how they looked coming out of the machine.

And again, with our scale 1:48 man. There are some very minor blemishes in the gear teeth, but I'm totally okay with that and am pleased with the outcome.

Another view… I made the shafts hollow to reduce resin consumption.

I have all the propulsion system parts loaded (by WiFi) in the printer, so all I have to is pull the job off, fill up the vat to account for resin consumption, press go and in a few hours more parts will appear. Here's what it looks like in time lapse from the printer's build in camera. It's fascinating and a little sci-fi to have parts appearing of a 1/2" deep pool of resin.

Hope the video works….

The figure really adds scale to the work. It's pretty neat!

The HP print looks spectacular!

Even that very complex throttle assembly printed perfectly and I left it attached to the upper half.

I didn't know if it would work that way. It did!

The rotor is a beauty with no warpage and clearly define discharge-end blading.

And that very thin cross-section exhaust funnel seems to be okay too.

Lower shell is nice and clean and should work as drawn.

I haven't trimmed it or post-cured it so things can still break.

They come off the printer like that! WOW? So clean.

 

[SaparotRob]

That's sensational. It's hard to believe that much fine detail in one go.
