10. Molding and casting¶
This week I worked on molding and casting to broaden my skills with different fabrication methods.
indivisual project¶
Designing in Fusion 360¶
I decided I would make a heart shaped choclate with a gap in the center to put something in the center.
To create the heart shape, I used the curved line tool to complete half of the heart, and then I used mirror to complete the symmetrical shape. I did this once for the inside heart and once for the outside heart.
With the sketeches complete. I extruded the exterior by about a half inch, and the inner heart by half of that. I then used fillet to curve the edges of the pocket to create the shape of the chocolate.
In the screenshot above, you can see a preview of the wax block the mold will be milled out of. this was simply extruding a rectangle with the proper dimensions (5.88in x 3.47in x 1.47in). and cutting out an area to place my design.
milling the wax¶
Now that the design was done. It was time to take things to the axiom and mill it. I was assisted by my instructor Brandon, and in a short time, I was ready to create my mold
making the mold¶
(It should be noted that as of right now, I have forgotten which plastic mixture I used and need to ask then instructor that was there with me)now it was time to create the mold itself. I used 100 grams of (Liquid A) and 10 grams of (Liquid B) and poured that into the wax. After that. It would be time to wait and let time create my mold
adding the chocolate¶
After about a day, the mold was ready to add chocolate to. After placing melted chocolate into the mold and placing that in the freezer for the short time, my treat was almost complete. The last thing I needed to do was add peanut butter. It is a good thing I took pictures when I did, because my completed treat lasted for about 45 seconds before I took my first bite. What I was expecting to taste like a rees’e peanutbutter cup ended up tasting more like snickers.
