Actually it’s not that hard to work out;

1ml = 1cm3
1000ml = 1 litre
24 inches less 3 inches = 21 inches
1 inch = 2.54cm
21 x 2.54 = 53.34cm
53.34 (wide) x 53.34 (long) x 1(deep) = 2851.6 cm3

2851.6ml or 3 litres

Edit - Ooopsy we both worked it out at the same time.

Roughly 1g = 1ml = 1cm3

There’s also a discount code that gets you 10% off LUKESAPS10 I think.

 

[RonBSM]

I'm really not sure that 1ml equals 1cmsq mind.

 

[ClockworkOrange]

Nah a millilitre is just another way of saying 1cm3 it’s the same thing - I’m just not sure 100% if weight is 1 gram I think that’s water not this resin @undertaker will know.

 

[RonBSM]

Yeah well good job I took it in millilitres not weight then... as what we are doing is volumes not mass.

Essentially, 1 full kilo came out at 860ml (860cm³) plus 19ml accelerant (19cm³) for that volume.

So 879ml (879cm³) in total for pouring from a 1kg pack.

So we can calculate from that.

2851.6cm³ requirement for you then is actually 3.25 bottles of resin for your needs. By the time you have an amount of shrinkage across your board I think you'll just want to go for full 4kg/4 bottles.

I can’t find the weight per ml of the stuff I linked but google suggests that clear casting resin is something like 1.055g per ml so for our purposes once you add the catalyst 5kg is 5 litres.

Anyhow I’ll be needing more than the litre I’ve already ordered.....

Granted.... but I literally poured out the 879ml from this one kilo pack, so without having weighed it beforehand and assuming it was correct then its heavier per ml.

Or I've been short changed in resin.

Either way.... LOL

 

[ClockworkOrange]

The other thing to be aware of is that stuff sets faster the thicker you pour it, it takes ages for thin layers to set. As I found out when I mixed up a big batch and it went to a gel / half set state before I’d poured it all.

But yeah these printed bulkheads are great. Just a shame they take so long to print. I just don't think about the time, I just keep the printer churning them out and I keep onto other things.

Sounds like you should get a strip of 3-4 half bulkheads, make a rubber mold and get some more resin in action casting them in batches.
Probably a lot quicker than repeatedly printing, especially if you’re doing loads of the same thing.

Fair point. However, the printer is new so I'm not over the novelty yet haha.

And I'm currently printing all the time at the moment, various things so I'm filling time with bulkheads. Its helping me to not go balls deep and try doing 19 boards at once....

That seems about right.

The chemical data sheet from that resin says:

BULK DENSITY : 1,1 - 1,15 g/cm3 (ISO 2811)

Take the inverse and that equates to 0.909 - 0.870 cm^3 per g. (presumably ISO 2811 is somewhere around room temperature and pressure )

And, yes the millilitre was originally defined as the volume of 1 g of water, but is now just a unit of volume equal to 1 cm^3.

 

[RonBSM]

So, there were one or two bits with some shrinkage that caused a little bit of separation.

Other than that, perfect, no bubbles. Clear.

Oh well, I'll just pour on another kilo.

 

[ClockworkOrange]

I’m wondering if it’s the thickness your poured or the product? That one I linked and have used before didn’t seem to shrink but I was pouring in 5mm layers.

Easily fixed though just pour more on top or fill it with sand and make it a river bank.

 

[ClockworkOrange]

Ta @undertaker I knew you wouldn’t let me down! I couldn’t find its weight to cm3, but that would seem to tie in with the volumes @RonBSM was getting with his real world experiments.

So 3 litres it is!

 

[RonBSM]

I'll pour more.

Its obviously more expensive to pour more, but it is fun.

Also, go with 4 litres. Deeper is better!!!! I know looking at this pour that i want it deeper now. The resin is SO CLEAR that I'm going to have to make the next pour (since it's grimy toxic sludge) a lot more murky.

Also I think that I'll add less catalyst next time as well. I think perhaps it went off a little too quick and that caused the separation.

Ah the fun of science.

More Hexwraith Flame it's gonna be!!!

 

[ClockworkOrange]

I tend to mix in Vajello livery green and it makes it more sludge like / less see through and therefore you need to use less resin.

That said I want to make a Frostgrave board next with a river that you can see fish through, complete with some ice and snow.

 

[RonBSM]

...that you can see fish through, complete with some ice and snow.

Well this stuff is crystal clear.
