Molding and Casting
This week assignment was to design a 3D mold, machine it, and cast parts from it following these steps:
My idea was to experiment with the geometry of molding and the constraints from using a 3-axis milled mold and at the same time make something useful. so I decided to mold and cast a phone charger holder which I urgently need as I always run out of battery and I always carry my charger around!
Design a 3d model - positive mold
I used solid works to built the 3d model for the positive mold. I created first a 3d cube pieces that had a lot of difficulties to mold. After a lot of trials about how will my pieces work, I finally decided to do one positive mold which will give two symmetrical negative molds.I had to take in consideration many factors :
I used the Roland SRM-20 machine to mill the block of wax.
Negative mold
After the preparaton and filling the block of wax with silicone, I had to keep it dry for 12 hours and try to fill the mold again for a second symmetrical negative mold.Because of the symmetric in the mold I had to 3d print fixing points so that the parts can fit together perfectly.
Casting
For the casting part, I have used:Download the file here : 3d module - solidWorks
