Have fun and don't make full scale models!

[tricycleboi]

I like how he prints the scissors gripper to prevent himself from touching the dichtol but still dips his fingers in it to use the grapper

[Twig_ash]

That creation in the thumbnail is absolutely *imploding*

[noen-_-]

I love all the little jokes and reverence in the video, makes the video way more fun to watch and gives a nice atmosphere.

In industry, reinforced O-rings are used to seal vacuum lines. These have a metal ring on the vacuum side that prevents the seal from slipping.

[CarlinPlayz]

That 3D metal sub was cool. You're probably right that it could go deeper then the real thing

[sydnerd]

Props to JLCPCB/3DP for supporting this channel, shame others wouldn't because you folks are doing an amazing educational and inspirational job combined with top tier engineering.

Cheers from the openROV team. We actually thermally annealed our PLA to waterproof ours back in 2014, and this worked quite well by boiling them in hot water just to the point of deforming and then letting them cool. If you get the temp correctly it will work, though less well for solid fill.

[waterstudio]

I have some reasons for love your videos:
1. Good video editing
2. Stilling voice
3. Gripping content

[Arek_R.]

Doing second process with the dichtol stuff probably will seal it even more.
Btw. another technique to seal a FDM 3DP is by printing it in ABS and then doing acetone smoothing, it dissolves surface of the part and once dried creates solid layer all around.

You can put the print in dichtol and put it in a vacuum chamber. This allows air to escape from the pores and at normal pressure the dichtol diffuses into the pores.

[bendixflight]

0:55 better performance than the real thing

[saturated]

Would be quite interesting if someone made a full scale model for testing!

[segment]

To both prevent water damage your electronics and make the sub survive a deeper dive you could submerge the electronics in baby oil.
Then the submarine drone don't have any air in it, thus can not break from over pressure.

Panowie wysoki poziom. Fantastycznie opowiadacie o swojej pracy. Czapki z głów. Powodzenia

[LeeRox]

You could use a "clear transparent" setting for getting a really solid print which reduces gaps in between layer walls

[Travis]

I used to repair cracked/seeping plastic fuel tanks by pulling a vacuum on it, then applying epoxy. The same could be done with your printed vessel and the dichtol. Also pressure regulating the hull is a good idea.

i died laughing when i saw the submarine

[AnotherOtherMan-alive]

When using a gasket or o-ring, you need to design around it with a groove for it and having multiple sealing layers. You want to maximise the path the water takes to get in from a deliberate opening.
