Rov Reboot (3D Printed Rov)
Re: Rov Reboot (3d Printed)
It will only be two pieces now... with splitting it in half for ease of printing I really don't need the separate end caps anymore. I also designed it with thinner walls to be a little lighter and it will also print faster this time around.
The fun continues...................

Re: Rov Reboot (3d Printed)
Fortunately is was an easy fix, only one dimension to change and a few other easy changes that it effected. Using the section view this time I can see the walls should now be thick enough to hopefully resist the warping during printing. This view also shows how I had to use a slopping angle on the inside edge for the cut out of the relay box. This will reduce the inside volume a bit but will allow it to be printed without supports in there that I probably wouldn't be able to reach to remove later on. These are some of the design considerations you have to think about when it comes to 3D printing parts.
One half of this is going to take upwards of 11 hours to print. I think I'm going to have to wait another day to start it, if I start it tonight I don't think it will be done by the time I have to go to work tomorrow.

Just noticed this build thread, Very Cool it is amazing to me what you can accomplish with these 3D printers
Looking great

Re: Rov Reboot (3d Printed)
Off to do some volume testing.....

Re: Rov Reboot (3d Printed)
i'm flabbergasted, thats totally awesome!!
Re: Rov Reboot (3d Printed)
On a side note the print isn't very water proof as I had some small leaks while filling it up. I only printed it at 80% infill and with 3 Outline shells and 2 Top and Bottom layers (I think the top most layers on the curved section is where the leaks were.) So sooner or later I will increase these values and print a test piece to see if I can accomplish a print that at least stand up to a bit of pressure. Anyway that's a test for another day.....
I hope this micro balloons buoyancy stuff works at depth, I all ready have some ideas to make molds for tethers floats using this method.

Re: Rov Reboot (3d Printed)
micro/macrobaloons work just fine Steve.
I've got a chunk of 4000m rated buoyancy, which i was gifted for my Mk2 ROV, it's very heavy due to being 4000m rated but it's basically just microbaloons and epoxy.
just make sure you don't pour too much in one go or the epoxy could suffer cracking, though with microbaloons it's not much of a problem.

Now I wait... and see what happens
