An advantage to 3D printing is that users can print prototypes from the same material that will be used for the final product. The same holds true for creating 3D molds and patterns, which historically accounted for significant cost and time delays due to outsourcing the work to another party. Molds are invaluable for a variety of products, from turning 3D printed parts into metal parts to creating food-safe molds and even jewelry molds. You also can easily create a one-off mold for yourself or a customer, which allows the freedom of unlimited creativity to come up with a truly unique design.
