HELIUM CAR a 3D print once more.

Nice. It's exciting when you discover you can print things in larger sections or one piece.

Does the reservoir hold enough resin to cover a 24 hour print like this one?

dont know

it holds a liter.

I can't wait to see the finished print.  I don't think you;ll need much in the way of supports except along the horizontal members.  Any thoughts about splitting the tank section into tanks and ends?  That way you can hollow the tanks and reduce their weight and resin usage. You would have to have drain holes.

The tank holds 1.5? liters plus an additional litter bottle in the auto-filler.

Good work!

the outside end tanks are actually 1/2 tanks; and then 3/4 tanks at each corner.

the inside tanks are only there at the ends.  So the group of  tanks inside is hollow which can be a problem because of cupping; so I need to add some openings at the ends.

Do you have a Jupe?

Alan,

I would be interested in purchasing a Helium car off of you if you decide to sell them.

Alas, my Elegoo Saturn can't print something as large as o-gauge freight cars but at least I can print lots of figures & details

As a Navy Vet, I would love to have one.

Put me down for one as well!

Guys

Once again I must remind you that this is not the buy-sell forum.

I am not supposed to be  offering anything for sale here.

So please don't ask or the thread may be deleted.

Thanks.

My nephew in Colorado has our Jupiter.  He likes it, but because it requires a lot of resin it is reserved for only models that require the big build volume.  We both have a Saturn and Mars.  We have been making small items while developing CAD models of European style railcars.  In other posts I posted this picture of a PRR F22 flatcar printed in one piece on a Saturn.

@AlanRail,

This looks great!  So are there ready made decals for something like this?

Update:  I looked up the printer, and it looks like it's on sale for under $1,000 direct from the manufacturer.  Can that be correct?

Decals. There is a supplier that has ogauge helium car decals.

Jan - I planned on doing the truck frame in acrylic.  My thinking was that a resin frame as you  have made would not be strong enough. Is it?

I'm not planning on stepping on it, but normal operations it is plenty strong enough.  It has fallen 7 ft without damage, but I think it hit on a truck.  Brittleness was the original complaint about resins.  There are resins out there that are strong and/or more flexible and/or less brittle.  It's just like metal alloys.  People have been experimenting.  One combination is 75% standard resin plus 25% Siraya Tech Tenacious.  Siraya has a whole line of specialty resins just like Formlabs.

My trucks were printed on an early model FDM printer and show layer lines.  I intend to reprint them using standard resin and see howl well they hold up to use/abuse.  I need to spend some time research resin characteristics.  I expect there has been some work done and reported on YouTube.

Looks like another cool project.  I'm not familiar with helium cars, any pictures or stories behind them?

The new printer sounds like it really expands your capabilities.

Wow, very unique car and quite an undertaking too.  Looks like a fair amount of interest for such a niche piece of rolling stock.

As  young kid I remember seeing dirigibles in the air around Pittsburgh.  I would think that this car would be correct for post WW II,late 40's,up into the mid 50's.  I sure would go for one if offered.
