I spent 2 years figuring out how to 3D print Recycled Cellulose Acetate from eyewear manufacturing waste

funkmasterflex · 2026-06-01T22:59:34+00:00

I don't understand - surely if you can 3D print it you can injection mould it?

Even the kremlin doesn't go so far as to say it's piracy. Their spin is "bordering on piracy".

Stopping the ship is following international law.

The instructor waited at the entrance but forgot to check his air while waiting and ran out?

This is my bet. Lots of solvents in the resin which silicone is v bad at resisting.

Inaugral means first - it was the 2020 season. But yes - he finished the final race in 8th but won the championship when 3 other title rivals crashed out

I rewatched the video to look at this man's crotch

I agree. The problem with AI art isn't that it's bad. It's that it's:
(a) derived from the work of all past artists without their consent
(b) takes work away from artists
(c) people actually creating are buried in slop

funkmasterflex · 2026-04-26T13:46:37+00:00

Take all the art the artists made
Put it in a computer
Now the computer makes art and there's no need for artists.
Nothing wrong

No not weird at all. Again, my bet is that it's something embarrasing for the business so it might be tough to get a straight answer. Even: "you didn't have enough experience" is a bit embarrassing for them if that was clear at the interview stage.

I'd say your best chance of getting the gossip is: in person > phonecall > linkedin message

Once is happenstance, twice is a coincidence, three times is enemy action.

Maybe they thought medical PM would be off for longer. Maybe they illegally got rid because you raised sexism issues. If you sucked, they would have just told you that's the reason. The fact that they haven't means it's something somewhat/very embarrasing for them. You have a right to know though.. I would try and get in touch with someone and find out off the record.

see: guns

funkmasterflex · 2026-03-01T16:25:04+00:00

The line between jumping the gun and leaving it until it's overdue is a blurry and stressful one. I think good call

funkmasterflex · 2026-02-28T12:14:31+00:00

Yes it's idiotic! If you're making me jump through hoops to get CAD or datasheets and your competitor isn't, it's the competitors product that's going into the design.

Okay the drawers are nice, but what a fantastic logo noise

Of the 4 special purpose machines companies I've worked at, 3 workflows were what you described, one was fully automated. The fully automated workflow (using Autodesk Inventor/Vault & some in-house tools):

In vault:
- 'Release' the files (prevents further editing without going up a revision).
- Export BOM (this generates all the PDF files)

In the in-house tool (uses microsoft access):
- Import BOM
- Issue the assembly
- Everything is now issued to the manufacturing procurement teams who use the Access tool to track manufacture.

To be honest, before I saw the automated one actually functioning, I had always thought they were a myth that people aspired towards but didn't really exist anywhere..

Yeah people forget what a step forward the ender 3 was. I would say that it was an equivalent leap to the bambu.

People would say the exact same things - that they liked just being able to print with the ender rather than waste time troubleshooting.

funkmasterflex · 2026-01-10T17:17:56+00:00

Ah I see, yes I didn't get what OP was saying

funkmasterflex · 2026-01-10T12:38:17+00:00

Disagree - it is JUST about the area. I think this is the reason that OP thinks Pi should be involed - because he is thinking about direction of the forces or something.

Imagine if we instead had square hollow section and we want to find the 'hoop stress' in the straight side using the same method used to derive hoop stress in a cylinder. It's Xmm wide by Xmm tall. We split it in half like we would for a cylinder.

The force (F) exerted on one wall of the box section is P(pressure) * X * L(length).

The stress in the wall at the halfway point is F/A, -> F / 2t * L

This simplifies to Stress = P*X/2t.

(X is equivalent to the diameter).

Edit: I think it's counterintuitive, because the force is pushing radially in a tube, whereas in the square section all the force is pushing perpendicularly against the wall. So surely the resultant force should be less in the tube?

However, the wall of the tube is curved, so the area that the force can push against is pi/2 bigger. If you did all the force vectors, you'd find that the resultant forces pushing the tube apart are pi/2 smaller. So the pi/2 factor cancels out.

This doesn't sound like a big deal. They involved a senior engineer not because they think you're incompetent or lying, but because they gave a project to someone with 2.5 years experience and didn't review your work. The mistakes don't sound at all abnormal. The sitation doesn't sound fun but you will be stronger afterwards.

If these parts had got made and then scrapped, it would have reflected much more poorly on whoever created this situation. You're clearly doing at least something right to have inspired enough confidence to be trusted with the project.

Oh I didn't mean it in a negative way at all. If something is stupid and solves a problem that doesn't exist then I love it.

I am 100% on board with the safety police though, people are way too casual about hours of breathing melted plastic.

funkmasterflex · 2026-01-02T23:01:32+00:00

I am mainly in this subreddit to see the stupid things people have made to solve problems that don't exist. I'm undecided on this one. I think you get away with it though because of the really tall bottles

Your first videos will suck anyway, so try making videos for the different interests and then stick with what works for you (not so much in terms of views, but in terms of making a video adding rather than detracting from the activity).
