The ExOne Company announced that innovative molded fiber technology supplier, Celwise AB of Norrköping, Sweden, is using metal tools 3D printed by ExOne in 316L stainless steel for its patented method of transforming wood and other cellulose fibers into a wide range of eco-friendly packaging and products. Invented, developed and patented over the past 10 years, Celwise technology aims to transform the paper and plastics industry with its innovation, which produces a water-resistant molded fiber product that looks and feels like a luxurious blend of wood and plastic. Celwise technology is enjoying rapid success, with adoption projects now underway with a wide range of global companies serving many industries, including consumer products, food and beverage, cosmetics, and electronics. Celwise’s patented process includes unique tooling and machines, as well as a novel process, to deliver its final product. Common cellulose fiber-based (paper) product manufacturing slowly removes water from cellulose fiber for molded products that must be coated for water resistance. Celwise, however, rapidly removes water in a new process that enables cellulose fibers to re-bond with each other quickly, creating a new type of paper product that is strong, wood-like, and water-resistant. What’s more, because a series of forming, transferring and pressing tools are 3D printed using ExOne binder jetting technology, the process gives Celwise even more design freedom to develop their client’s products. ExOne’s binder jet 3D printing transforms powdered materials metal, sand or ceramic into highly dense and functional precision parts at high speeds. An industrial printhead selectively deposits a binder into a bed of powder particles creating a solid part one thin layer at a time, similar to printing on sheets of paper. When printing metals, such as the Celwise tools, the final bound metal part must be sintered in a furnace to fuse the particles together into a solid object. Binder jet 3D printing technology is viewed as a desirable and sustainable production method, largely because of its high speed, low waste and cost, as well as material flexibility. ExOne is now providing prototype and production tools to Celwise specifications. While other metal 3D printing processes can produce the types of tools required by Celwise, Pierce estimates that ExOne binder jetting technology delivers a 20% time savings over those processes as well as a cost savings of 30-40%.
