Hi everyone.
These pics are my first prints and casts with soluscast.
As in previous post about soluscast there were lots of suggestions in curing and casting and lots of fails i decided to make new one.
PRINTING
1-These 4 ring model were printed in 2:45 hours.
2-Cleaned with alcohol then rinsed in clean alcohol and stayed there about 10 mins.
3-They cured in 2 different times. Both in plastic bottle full of water. My cure unit is a nail dryer with 4، 8 watts lamps and i added two more at its bottom.
Two models in right side were cured in 6 houres. It was long time so it causes them to crash in some places.
Two in the left were cured in 2 hours. It was enough and they were fine. As you see one of them is a heavy ring.
Water temperature reaches about 60 degrees.
CASTING
1-As i notice The most important thing about this resin is your INVESTMENT.
I suggest you to buy G3D SYNERGY.
2- mix it 38:100
3- leave it 3 hours
4- put it in oven. This was my oven program :
Ramp to 250 c in one hour and stay for another one hour
Ramp to 400 c in one hour and stay 2 hours
Ramp to 800 c in one hour and stay 3 hours
Return to 700 c and stay another 2 hours.
Then i vaccumed inside flask about 0.4 bar(important).
Return back to oven for another 1 hour.
I cast it in 700 c.
And these are the result.

Cuted Rings

Very very nice!

An excellent example of design, print and casting.

I really like your designs. Great work!

Thanks for sharing.

Thank you

Excellent !

Are you vacuum casting or centrifugal?

Looks like they don't sell that investment in the states, where are you buying it at?

I use vacuum casting.
Its a british investment. It shwbe available in us.
I used to use prestige optima for my b9 models. I think that should work too. But synergy investment quality is much better.

Amazing prints and casts! Thank you for posting your results.

What type of kiln/oven/furnace are you using to burn out the prints?

You mention that vacuuming out at 0.4 bar as being important. How did you go about doing this? With a vacuum chamber or an actual vacuum? How did you measure the pressure?

I use an electric kiln. It can reach 850 c degrees.
I vacuum all of my resin models. As you can see my casted tree was all resins. Vacuuming flask for resin models makes sure you will have no ashes or unburned resin and so a better cast. Then you have to return it to oven for at least one hour.
I vaccum my flask with my vacuum casting machine. I simply put my flask upside down on its vaccum chamber
And turn its vaccum motor on and it has barometer. When it reaches -0.4 i turn it off.

Do you have additional air holes or vents in your kiln to improve combustion? What is your ramp rate when moving between the temperature stages?

I see. Do you know if you see any debris in the machine after you do that? That is a very interesting way of dealing with the ash.
