PROCESS

>>> DESIGNING
I made the 3D model in Sculptris and divided in 2 parts (positive and negative) in Rhinoceros.

>>> MOLDING
I used industrial wax and the MODELA machine to make my positive and negative mold.
In this case I used the knowledge acquired in ELECTRONIC PRODUCTION about Modela machine.
Paremeters:
I needed to repeat the process twice. * Mill: first: mm, 1/8, wax, rough. | second: mm, 1/8, wax, finish

* Tool diameter: 1.875
* Error: 0.9
* Top z: 0.0
* Bot z: -4.2

After made the firts molds I had this result.

So I did a new and better version.

>>> NEGATIVE MOLD
Before to do the casting I needed to cover the imperfection of my mold with glue.

After using dry Urethane rubber (PMC-121/30).
The PMC®-121 Series urethane rubbers feature convenient one-to-one by volume mix ratios. PMC®-121/30 Dry and PMC®-121/30 Wet are exceptionally strong and abrasion resistant for soft urethane mold rubbers. These rubbers will meet the stringent demands of production casting of wax, plasters, concrete, resins and epoxies

STEPS: Combine equal amounts of liquid parts A and B >>> mix liquid rubber content thoroughly >>> pour over prepared model and let it cure to a solid, flexible rubber mold >>> demold to reveal mold cavity.
This was my negative flexible mold.

I had some problems with parts I divided in rhinoceros, so I could not use both parts.
