Last 3D Printed Automatic-Resin-Mixing Vat Now Printed And Assembled

This is just a short video update to show you all where I'm at with this Automatic-Resin-Mixing Vat Project.

As always, my video quality is very low so again I'll be asking you to pause the video whenever you see any kind of text coming on screen.

This text is generally something that I screwed up during my ramblings or something I forgot to include.

In addition to this PETG filament 3D printed prototype resin vat, I'll also be machining two additional vats out of HDPE plastic within the next couple of days.  That way if my torture tests fail  to produce the desired results I'll still have a couple of usable Automatic-Resin-Mixing Vats to work with.

There is an embarrassing side note to all of this.  It's something that I had not taken into consideration in the designing, machining or printing of my resin vats.

I had not considered the fact that with the larger inside diameter hoses I'll be using to pump my resin into and out-of my Automatic-Resin-Mixing Vats, this means that the four or five ounces of resin I have left to work with will not be enough to actually print my next batch of single cavity bullet molds.

Initially everything would work as designed but, even if I put all four or five ounces of the resin I have left into the vat, enough of it would be sucked out of the vat in fairly short order that I'm afraid I'd run the risk sucking in air and blowing out bubbles on the input flow end.

I can't run the risk of bubbles getting into my resin mix. That would be a terrible mistake to make.

This just means that I'll have to save up some more nickles and dimes to buy another full bottle of the High Heat Resistant 3D print Resin before I can actually print more bullet molds.  With the thoroughly mixed resin that this Automatic-Resin-Mixing vat was designed to deliver, there's a far, far better chance of ultimate success.

I think it's still going to work out for me because I still have the HDPE vats to machine and test, followed by the fabricating of four more input and output flow ports and possibly having to fabricate a couple of the small rectangular metal frames that fit on the underside of each resin vat.  

The 3D printed frames I'm using now seem to be working fine but I'd feel more comfortable with ones made of a more rigid material than PETG filament.

By that time I should have the money saved up to buy another bottle of resin.

I'm inching my way toward the finish line.  I can't wait to print out that next batch of bullet molds.  I'm optimistic about the greater durability of my next set of those prototype bullet molds now that I've come up with a way to keep my resin thoroughly mixed.

In the end, I believe that all of this will have been worth while. Not just for me but for any 3D-Print-Nerd that happens to be a bullet caster or mold maker who dreams of 3D printing molds that are able to cast certain metals with. 

Thanks for sticking around for as long as you have.  I'll be back to show you all how the machined HDPE plastic Automatic-Resin-Mixing Vats turned out.

Even though it's outside the scope of a couple of the 3D resin print groups that are following this project, I may video record some short snippets of the machining process of those HDPE resin vats too.

I'll be back.
