As 3D printing steps forward, the hope is that it will absorb most traditional manufacturing functions. If this is to happen, the common thermoplastic resins used in most 3D printers are going to have to be improved upon. Though printers have been made to work with metals and other exceptional materials, the printable thermoplastics remain wanting in terms of their mechanical properties. In particularly, they lack an appropriate level of strength for load-bearing applications. Carbon fibers have managed to address certain needs, though they are too costly for many uses.
American Process Inc is currently working to solve this problem. This Atlanta-based company recently signed a contract with Oak Ridge National Laboratory to employ nanocellulose to create stronger printable plastics. The goal of this partnership is to create a resin that will replicate the qualities of aluminum in terms of strength and cost-effectiveness. Should they be successful in their ventures, it could improve the availability and quality of services provided by 3D printing companies and rapid prototyping groups throughout the world.
