<p style="color:orangered;"> <i>This week is a fun week. Because you can replicate a 3D design, much faster than with a printer and in different materials. I'm going to try to create a two-part mold, shaped like a train. And I want to use food silicone to create chocolate bonbons in the shape of the train ...

<p>To make the design of the mold I use <b>Rhinoceros.</b> I create the train, by extruding planes or using spheres. As it is going to be a mold in two parts, I cut the final shape of the train in half using a Boolean difference with a flat surface. Then I prepare the wax mold, that is, I empty a prism and add spheres that are the <b>registration</b> to join the two parts. It is through the wheels that I am going to introduce the resin; on both wheels I create a kind of funnel, one to fill and the other so that the aie comes out.</p>

<h1>Conclusions.</h1>
<p>For me this is one of the most fun Fab Academy classes and that at the same time you do things with your hands, you investigate and you seem like a little scientist. This is the progress and result of everything I have applied this week. I am very proud and have had a lot of fun. 😊</p>

<p>Surely in the not too distant future, I will apply this manufacturing process to the possibility of creating several model pieces, much faster and in greater detail than 3D printing.</p>>
