Methods for forming metal articles are provided. The methods include forming foam casting molds from polylactic acid for use in lost foam and sand casting processes. The PLA-based foam casting molds advantageously reduce cycle time, reduce overall cost, increase reusability of the foam casting molds, reduce costs associated with shipping the foam casting mold, and improve yield and quality of cast metal articles.
