Week 12 Molding and casting

This week we are going to make a mold and cast something inside

For the third try I designed this little flower pot countermold on SolidWorks

Export as STL

Download Countermold STL
Import to ArtCAM, generate G Code to mill with 3mm Milling Cutter

Define zero


Machine it




Mix both parts of silicone

Cast silicone into the countermold. Let it dry.

Unmold


Now we cast resin into our soft mold to get the designed products. Let it dry



Unmold again. We could repeat this process several times, until the mold fails, here we proceed to repeat the process of making a new mold from the countermold.

For the second try I downloaded this Eagle Head and modified on Rhinoceros to make the countermold. I cutted the eagle head in half and then surround it with a box with demolding angle.

Print the countermold
Make a mix with silicone, cornstarch and baby oil
Oil the countermold, cast the mixture and let dry
Remove the silicone mold
Prepare white cement and cast into the mold
Remove the surplus and let dry
Unmold

I make a model on SolidWorks and then exported to Rhino to use RhinoNest

Then I generated G code with RhinoCAM by setting axis alignments, reference point, work zero, tools and operations
An then machined on the router

After this I prepared cement
And casted into the mold
