Week_13 Assignments
- Group assignment
- Individual assignment
We needed to test multiple materials that can be used in molding to make the mold itself or make the object out of it.
I have to design and make a mold to make a 3d body that has a smooth finish.
Group assignment
We tested Silicon rubber to make the mold and Polyester and wax (candle wax) to make the object. The Material we used was Generic material which has no recipe or instruction on it so we tried mixing ratios and what we found having great results for Silicon a ratio of 100g of silicon to 1g of Solidifier and for Polyester it was 100g to 2g.
A note don't hold the polyester solidifier mixture to long of after it mixed as it heats up and could reach a tempreture not comfortable or easy to hold.
These are the good results.
Individual assignment
I started designing a simple shape in fusion and I made it symmetrical to make it easy to design and cut time.
I used draft analysis to see the surfaces where the mold could stick to and make and edite the draft angle according to this.
I used Meshcam to get the gcode files and make the toolpathes.

I tried to machine it but I ran into some problems
