The ecosystem of 3D printing to fabricate objects from polymeric nanocomposite materials is important for wide use and rapid scale development towards high-performance materials. Other materials based on metallic, ceramic, hydrogels, and other non-metallic do not have as wide a range of properties leading to new structure-composition-property relationships. There is increasing interest in sustainable and recyclable materials. Nanomaterials together with sustainable biobased polymers can be used to enhance performance in thermoplastics, thermosets, and elastomers and their thermos-mechanical properties. In this talk, we emphasize the use of sustainable cellulosic and non-cellulosic additives to improve the performance of composite polymer materials. This has been demonstrated in the choices of 3D printing methodologies (FDM, SLA, SLS, VSP) which can make use of blended or formulated compositions of these sustainable filler materials. By incorporating nanomaterials with 3D printing new designs of toughened materials on commodity polymers, the value chain of biobased materials can be extended to higher values. 4D Printing will be demonstrated based on stimuli-responsive properties as reported.
