OK so first of all. If you havent done 2part casting, then read the description carefully
This is a 2 part cup pouring package. the cups have a ballshaped floor, so you can get all the liquids from the cup and so you wont lose any.
Why did I make it?
The Problem with casting is the cup shape. Please do not mix up the cups. One cup has a bar and one has a beak. The bar-cup is, so that when you print 100ml cups, then you know where to stop with pouring and the beak-cup is for APart and BPart of you 2k solution. The beak is for pouring and guidance of the fluid.
When calculating the height, I came up with a rough calculation of the cup sizes. Add a 5% buffer to the calculation, so you have enough room.
How do I know the right Cup-sizes?
Both cups are modeled in 1ml sizes (except for the printprofile. There It is meassured in 25ml). For calculating the right size the calculating is as followed
"Base volume" * (x/100)³ = “Desired volume” → z * (x/100)³ = y.........
An example: The cup is 20ml in volume and I want the volume that I would need for 250ml:
● 20 * (x/100)³ = 250 → (x/100)³ = 12.5
● x/100 = ∛12.5
● x/100 = 2.320794
● x = 2.320794 * 100
● x = 232.0794%
So the sollution is: x = 232.0794
What do the symbols mean:
● z: the value the cup currently holds
● x the scale that we want to get
● y: the value that the cup should have in the end
Why divide 100?
Simple. The scale of the object starts at 100% from the slicer per default. So if you start at 606% in the slicer per object, then use this:
z * (x/606)³ = y
For the root³ I used this site: https://www.omnicalculator.com/de/mathematik/kubikwurzel-rechner
Risks that can occure while pouring?
ALLWAYS read the description BUT in most cases there need to be 3 things checked:
● Do I have ventilated area?
● Do I have a respirator?
● And most important: Do I have any health issues!?!?!?
You should allways do outside if you have none of point 1 or 2.
Pouring guide
In my cases so far you have to do be fast, because the chemical reaction will hit pretty fast.
ALSO when the chemical reaction starts DO NOT TOUCH THE CUP. It can get over 100°C easily and you will get burns.
Thats why I stated in the printing file what materials you should use.
Dont want to scroll on top for the materials you should use for printing?
No problem. Here are they again:
● Strictly use ABS or higher. PETG can be used, but bare minimum and not recommended.
● Minimum: ABS/ASA/PETG
● Recommended: PA6/PA12
● Better: PC
● Best: PP/PPA-CF
Reason: HEAT, CHEMICALS
