c. preparing a mold (30) by providing one or more coating layers of a pre-defined coating material over the laminated template assembly;
d. providing pre-dried sand over the mold (30) to form a sand coated mold (30b);
e. de-waxing and baking the sand coated mold (30b) for melting out the template assembly (20) to form a de-waxed mold (30c);
f. pouring a pre-defined casting material over the de-waxed mold (30c) to form a casted mold;
g. cooling and solidifying the casted mold to form a casted implant (30e); and
