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 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.

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

Here's that YouTube Video in the correct format.

The parts being "clean" is also a function of cleaning in two alcohol baths and 15 minutes in an ultrasonic cleaner. But if you're referring to perfect edges and details, that IS a functioon of the printer and good drawing practices.

The printer continues to hum along turning out very nice parts. I test assembled the HP turbine. The rotor broke in the middle. I temporarily glued it back together, but am reprinting another. It appeared to be a structural flaw, and after reviewing the drawing, there were some discontinuities in the central core. I made some mods and in the slicer it appears to be nicely solid all the way through. It's set up to print with the main steam pipe. The rest of the turbine came out great with no changes necessary. My removal of the supports left all the throttles in good shape. Just finished on the machine is the entire HP foundation frame printed as a single part and it's appears to be perfect. I also printed the "steel" stiffener that resides on the fire room side of that bulkhead that provides the necessary to support the ledge on which 1/2 of the turbine rests. I have that part to display tomorrow.
The massive lower half of the main reduction gear box is done. As the rest of this work, this one was very nice also.
This part consumed a lot of resin! It supports the output shaft from the bull gear.
Looking at it from the bottom shows the lower half of the output seal and bearing.
This picture is a bill silly since there's no shaft supporting the big gear, but this shows where it resides and why the gear case is do darn big.
Creating a model of this complexity and novelty is like the aphoism about how to eat an elephant; "One bite a time." With each successful drawing and subsequent print, I am more sure that the project will meet my goals. And I've said this before. When doing a completely custom build, you're thinking on a few levels at the same time. It's very easy to get the forrest and the tree, or roots, moss, fungus…etc. It's so easy to get down to very tiny details before you have control of the overall design and how it will work together. I can just imagine putting a show together like Game of Thrones (GOT). My wife finally agreed to watch it. I saw it when it first ran years ago. When you look at the scope of the script, the locations it was shot at, the costuming, sets, and then the cinematography, you wonder how they do it at all. Each episode was like a 1st run movie. My project IS NOT that.
My daughter's, brother in law's brother is one of the two fellows who created GoT, D.B. Weiss. We had the pleasure of visiting D.B.'s family home in a Chicago suburb. We talked at length about the creation of the show. It turns out that a pilot was created, but it was terrible and HBO didn't want anything to do with it. Dan and David told Netflix that wanted to rewrite and produce the pilot. No one bit, but the president decided to give it a shot. The rest is history. Netflix made billions on that show over its 8-year run and the two fellows didn't do so bad either. It just shows that sometimes even folks that are supposed to know, do know nothing. His mom presented us the full 8 year set on Blue Ray DVDs. We fianlly are watching it.
