So, one thing I did note is that a lot of the PETG vendors these days have been ratcheting up the speed that their normal non-rapid PETG filaments are printable at as well.
For example, Prusament PETG is good up to 200 mm/s and Elegoo’s Pro PETG is good up to 270 mm/s.
Not really, although that was clearly a popular impression created by the 1980s Right Stuff movie.
Both the US and USSR had the A4/V-2 rocket and both the US Redstone and USSR R-11/SS-1 “Scud” were grown-up and bug-fixed versions thereof.
The US kept the Operation Paperclip folks going throughout the program, leading to Von Braun’s team designing the Saturn V rocket, even though the Redstone Arsenal / Marshall Space Flight Center folks didn’t design some of the other rockets.
The USSR kept their Germans under a tight leash and every time they designed a rocket, they’d have the Soviet team design the same thing, they’d compare, and then after a few years, they sent back their Germans to live in obscurity because the Soviet team had gotten good enough.
Thus big rockets ended up being a German ex-Nazi party member, Von Braun and his Saturn V vs a Ukranian, Korolev and his N-1.
Thus, an astonishing number of rockets are based off of the A-4 design, many of them with the Scud as the middle step. And neither America nor Russia gets to really take credit for their chief designer, where obviously both men were mostly acting to provide structure to the giant armies of engineers who did the actual work (but doing it well, the USSR program really screwed things up after Korolev passed away). But there was a bunch of really neat bits of rocket science that the USSR did in the 70s-80s that was well above where the US was specifically because while Korolev was Von Braun’s generation, most of the newly taught Soviet scientists were not. Where, again, the real problem was that Korolev didn’t have any good successor leaders and the USSR was in a state of stagflation.
And you can say many things about the USSR space program, but they were significantly less “nazi” than the US program.
