Start with PLA since PETG can be finicky with moisture.
Garages are nice but try to keep drafts to a minimum. PLA is more forgiving there too.
Have fun tinkering and figuring it out. There’s just some skills you’ll acquire as you go. Slicer experience giving you an understanding of orientation for strength and/or to minimize the need for supports.
PLA is also cheap enough to just figure it out. You’ll have bad prints, regardless but you’ll also make some cool stuff too.
Math is the language we use to write pseudo-code for the rules of the universe. It allows us to reasonably predict and share/write our understanding of the universe.
The best algorithms then match with the actual universe even if the real thing doesn’t use the math (looking at you -1, infinite points and black holes)
Basically you have 2 extruders and push the filament based on what’s needed.
You do need to purge the melt zone and I these don’t work well with different materials (PLA in one, ABS the other) because of PLA being too hot at ABS melt temps, etc.
As for these knockoffs if it’s cheap enough maybe but I can’t imagine the heat break being too good and it seems prone to jams.
It’s so weird how the character went from being an ad campaign to beloved tv and movie character.
It would be like the guy who smashed appliances saying “prices? smashed! Our competitors?! SMASHED!!!” Having a solo acting career.
Which leads me to cinematic perfection. The Advengers. A group of TV ad characters joining forces to save the world from an unstoppable force. A fed up Maytag repair man.
Don’t forget other such lovable characters as Local Town Attorney, Late Night blade master and their dauntless leader cable access QVC knockoff host.
And to add to the conversation(if there’s anything incorrect please let me know) from videos I’ve seen by MentourPilot, Captain Joe and online sources
The process will most likely look like the following (assuming an emergency descent is needed because the cabin can’t be pressurized like with the window vs some smaller hole air leak):
They will put on their own o2 masks (it’s critical to do this as you can lose consciousness in under a minute)
They will set the transponder to a code that denotes the emergency to both ATC and nearby traffic
They will radio the distress both for ATC but also nearby planes to give them a heads up that they’ll be rapidly descending. If it’s in a high traffic area they may wait for approval to begin descent (and you can be sure ATC is going to be moving planes out of the way.). If it’s taking too long they will begin descending anyway.
They’ll announce to the cabin that they’re doing an emergency descent
They will start a rapid descent to 10,000 ft (if terrain allows it, otherwise down to whatever they can safely get to). This is because the emergency o2 is limited to about 15 minutes.
Some interesting things I learned about this.
They will often use autopilot for the descent and level flight. This is because of limited visibility and a risk of possible issues caused by low o2.
They turn on all lights to make sure they’re as visible as possible to other traffic.
This descent will be really unpleasant. Not a gentle descent but the safest one (especially if they’re unsure if there’s any structural issues) they can do. Which will be quite a bit steeper than anybody is used to.
So passengers on the plane will experience this as:
Loud rushing noise. Possible moisture filling the cabin now that you have outside cold air mixing with warm air and surfaces inside
Masks dropping and seatbelt signs
Shortly after the Captain saying “Emergency descent” 3 or so times
Flight screw scrambling to seats and putting on masks
The sound of the wings adjusting for speed brakes, shuddering from the flight profile change,
The sounds of the engines being revved up to the planes maximum speed as the nose of the plane tipping down. It will feel like it’s faster than it really is with the shift in gravity followed by being pressed back due to the increase in speed during descent.
The plane shifting as they turn away from the main traffic area as they descend (unless told otherwise by ATC, etc)
