Here is the wax mold filled with silicone
And here are the silicone rubber molds ready
Casting
Now I had to use the mold to make a new
object. First thing I had to do was to
was to make a hole in the silicone
rubber so I could pour the something in
it. This was something I probably should
have done in the computer but with a
sharp cutter knife and a drill I made
two holes, one bigger for the material
and one smaller for air to get out.
We had some Gypsum cement which I used
to make a new knight. To get the cement
wet I put some water in it, I heard
somewhere that the cement should be as
thick as an yogurt. When I was satisfied
with the thickness of it I got the
silicon rubber, first I put some soap in
it to make it easier to take the stone
knight out and then I put them together
and taped the sides so the cement
wouldn't leak out on the joins. Next I
got a stative and put the silicon on it.
Then I took my cup of wet cement and
poured it into the silicon mold. Now I
had to wait.
This is what the
stative looked like
The first one was not
working like I wanted to. The silicon
was not totally right so the two sides
where offset. Also I didn't put enough
cement in it so I didn't get the
bottom part. Round two went better, I
was more careful when I tapet the
silicone and put more cement in the
mold. Now I got good looking knight
the same size as the original one and
the one I printed out in the 3D
printer.
Here is the first
knight
And here is the knight perfected
Making plastic object
I have tried to use liquit plastic once
before and that did not work out, the
plastic got stuck on the silicone and it
all the air bubbles blew up and destroyed
the object. Now I wanted to try that
out again for some reason it didn't
work out too. I have to ask for some
help the next time I try the liquit
plastic.
Here is the plastic
knight piece stuck in the silicon
rubber
I made to much of liquit
plastic so I found an old puffin
mold and put the remnant in it and
that worked out good.
Here
is a picture of the puffin
