11. Molding and Casting¶
Sounded as a fun week , yet I got happy too early . I tested positive for Covid so I had to stay home quaranteening with Bomba (the cat) and Sodawy (the laptop).
In 2 weeks I got better , thank God , and went to get back on track .
Reviewed the Group Assignment .
Design¶
Working on Fusion360 , I had a sketch of a cat paw .
Did some extroding to get the final Medallion I wanted .
Added the frame , registeration pins and pour

Process : First time roughing then Finishing
Set Tool
For Roughing I used the 3/32 Square .
and for Finishing I used the 1/32 BallNose .
Continue setting , Lines type
And before starting , I set my origin
After pressing Preview , I get to know estimated time for the process and I can see now the machine route
Roughing Done
And Finishing
and off to Mold2
Silicon¶
I made a mistake in the desing , Didn’t make walls . and the mold wasn’t deep enough .
So I made walls of wood , sealed by wax gun
Preparing the mixture with a ratio of 1:10
Probably I over-stir it as it came out very thick and mold wasn’t successful .
Try 2 , with 1:15 ratio , As I don’t want it to dry fast
This time it came out much nicer
Resin¶
Secured my two molds together using tape .
Prepared my resin with a ratio of 1 : 2 and a sprinkle of glitter .
And poured inside using a syring .
A lot of bubbles , yet I love it
