GENERAL OBJETIVE:
Molding and Casting
Design a 3D mold, machine it, and cast parts from it
This allocation should make a mold and get him a negative to occupy generate aftershocks.
The first is to obtain the basis for generating the 3D file and be able to model, this is done from CorelDraw, obtaining the contours of the logo FabAcademy as shown in Figure 1
Figure 1 Vectorizing in CorelDraw
Once you have the vectors can make an extrusion thereof to generate a solid, in this case a volume is generated with the image of FabAcademy in Rhinoceros 5, and then using Boolean operations subtraction extrusion was with an average area to generate a curve with the logo of FabAcademy.
Figure 2 Volume / Solid Rhinoceros 5
As shown in Figure 2, a solid which can be exported in STL format for 3D printing for example, or even what the case to model in Roland using FabModules was generated.
Figure 3 cutting routes FabModules
roughing the material in the bed of Roland work, in this case it will make use of jewelry wax is placed in green, and stick with some double-sided to fix it.
Figure 4 Wax Attaching the Work Area
Once the material has set as shown in Figure 3, you have to calibrate the machine to perform cutting, scratching the surface with the cutter and proceeds to make the cut.
Figure 5 Roughing Wax Jeweler
Figure 6 Cut Wax Finish (Mold)
For the negative of our wax mold can be made of various materials, in this case it will be made with silicone rubber, which allows a flexible negative and that can be obtained about 10 pieces of such negative.
Figure 7 Materials Getting Negative
To facilitate the process of stripping using a film which facilitates the process and have the consideration of the angles of the negative output can be easily removed (Figure 7) is made.
Figure 8 film layer Unmold
Figure 9 Draining Silicone Molde
Once emptied or placed silicone as shown in Figure 9 is expected to cure or vulcanize for later placing a cloth and make a new drain (to strengthen, thicken and prevent breakage or unmolding and easy handling.

Figure 11 Second Draining Silicone on Canvas
Once these steps are expected to cure / vulcanize silicone and unmold.

Figure 13 Molde and Negative thereof
In this case as it has a lot of detail you have to use a silicone with lower viscosity grade for the desired item.
