Casting Methods: Investment Casting - Investment casting uses a pattern made from a wax or a foam form. The form is then covered with a suitable casting media such as sand or plaster. When the casting media has set or dried, the form is removed. The casting material is then poured into the void left by the form.
Lost Wax - Lost Wax Casting Uses Wax Patterns as the Investment.
SLA Prototypes - Stereolithography
