This past week our students have been busy with the Molding and Casting assignment. Lots of beautiful little objects were produced and lots of sticky, liquid, chewy, blubby materials were stirred and cured.

Alessandra casted her lips and scanned the result with the Roland Modela, to then make a mold for chocolate. Check her page!
