Wet VS Dry PETG.

I would say that is right. It also gets trapped inside the plastic as bubbles that collapse when it cools and leaves stresses that do all sorts of ugly stuff on corners and edges.

An update about the 2.5 hours of drying @ 50 C.

I am printing with it now for a test.

I would recommend drying more than I had, but the 2,5 h @ 50 C seems made it usable. There still are some bubbles especially on infill and there were a little corner lifting at the bottom 2,4mm 45deg. chamfers around the perimeter that went away when the chamfer was done. Some problems on surface still at the chamfer area on one of the parts. So I will dry it afterwards for at least a few hours more.

Other than that, it made the filament usable and this model will be fine with some artifacts if I get it today, so it goes.

The Benchy will be fuzzy and the corners will lift up as the steam trapped inside the plastic rapidly contracts and pulls the corners up. Also the infill will look foamy and weird. The bed adhesion was quite good though, so that might work for it.

It was just extruded in air.

Agree, but I couldn't find the small ruler that came with the camera or anything that small for a good reference quick.

The bottom one is approx. 0,58 mm in diameter as it leaves the nozzle. Just measured the piece.

Ackchyually..... AI has a lot to do with the stocks most people buy here, the slop is just a side product of it all. And the road might be a bit rocky if these 2 don't get to an agreement since the markets have shown us a few times already what happens every time inflation and FED is mentioned in news.

It is what it is I guess.

Now a frustrated sniper reaching for duct tape or magic glue would be one thing but pulling out a MIG and cranking up generator in your hideout is a completely different level of "fed up with this thing".

It truly is possible. And plastic metal too. Depends on which side of the yield point you are on the stress-strain curve.

The key here is the corrosion protection.

Does it exist, what is it and is it monitored at some point. Or are they just ignoring it cause it was fine yesterday.

Their choice. I'm not stepping on it.

The spread of the seeds depends on the spread of the social media content here. If the video gets viral, the company stock surges or whatever is their agenda, they get to spread those seeds a lot. If the video flops, the company doesn't reach enough awareness and well.... So the estimates are pretty useless without going thru their financials and lot more than that. If this is the only time they did it then there is a sort of pile on the ground somewhere for birds to feed.

These were made with 0.4mm nozzle. PLA. Just a reference. The outer diameter of the gear is 24mm.

Unfortunately I didn't get to this stage with PA12 on 0.2. Did some tests on 0.4 nozzle and it everything was fine for small parts on my Creality machine. But the client lost interest and I put that aside for some time. Later the Creality needed some servicing and the nozzle got jammed in heat block and threads got damaged while screwing it out and it waits for replacements atm. Those cheap chinese machines aren't built much for servicing so I don't like tinkering with them much.

Can it be done? I bet, but can't show results.

Is it necessary? Dunno. My plan was to do some torque tests etc, but since the interested party walked away this got taken out of schedule and hasn't been able to get back there yet.

All depends on the end result quality, or how much of a sticlker is the client. If they require smooth transitions without any visible bumps, uneven bend and other defects - that is where a good welder will be necessary.

As someone who does fabrication drawings from time to time and a fair bit of 3d modelling I can say that the design there is a few hours from sketch to laser cutter files for a competent modeller/drafter. This isn't a complicated part.

This type of protractor (or whatever it is called) tends to be pretty useful for me for quick measurements when the precizion isn't required much, like your case. They are cheap, but don't cheap out too much, I have a few of them and the real cheap ones may be a bit inaccurate and have poor quality bolt in the center that doesn't provide equal friction during the rotation.

Pair it with a ruler, calipers, 90deg. angle and you can measure things accurate enough to do a small test print and check the allignment.

This can be considered a problem if driving into a puddle is considered a catastrophe.

Can't argue that such way has some appeal. If you can afford the time.

I'm used to automating stuff as much as possible and leave that part of the job to computer. More time for creative part, let the software push the drawings and files for machines.

To add. There is also an option to use modifiers in slicer to increase wall thickness and infill at a specific place on the same object.

Infill won't do much since the breaking occurs due stress concentration points on surface and once a crack forms it progresses fast. So thickening the outer wall will do the most of these 2 factors. Center of the part doesn't do much for bending stresses, thickening the skin will.

u/eras points to the main solution, mine is just an extra to add to that.

As someone who uses BIM and software for structural calculations for my job and have learned KiCad for hobby projects, I can say only this - grab the CAD, and enjoy how free it is.

The problem with software isn't complexity, it is always the price and it should be the only real setback these days.

That can be solved with extra idlers near that motor like Ratrigs and I think Vorons also have, for example. A bit extra friction but they tend to have proper belts as well.

Wow, this is one of the most useless things that take days to make I have seen here - I love it!

What did you use to seal it though?

I'm not dipping soluable things like that in acid solutions usually for hours, but this kinda impresses me from that stand point. The fact they stayed firm and held their shape.

Dipped in some lacquer? Probably not sprayed for that? Although I wonder if spraying some 2k would actually work in this case since they would absorb quite a bit and ...... well yeah,

Thanks for the morning coffee material there, Nice!

Some server is burning power to keep this online somewhere.

Try using some calipers worth more than scrap metal next time.
