Toxic toys were a major story last year. The Chinese toy scare stirred up a lot of new business for wooden toys made in the United States. That feel good story is now getting even a little better. Two American toy manufacturers are rolling out this year toys or games made with “thermoplastic biocomposite compounds”. These compounds are made of waste agricultural products such as discarded rise hulls and recycled plastics held together with patented additives developed by the National Research Council of Canada. The new coupling agents are a powerful moisture absorber that allow a tight bond between the wood fiber and the plastic. The toymakers are Sprig Toys of Fort Collins, CO and Rolco of Kasota, MN. The materials supplier is JER Enviortech International of Vancouver, BC.
These new 3D-printing technologies and printers include some that are truly boundary-breaking: a sophisticated new sub-$10,000, 10-plus materials bioprinter, the first industrial-strength silicone 3D-printing service, and a clever twist on 3D printing and thermoforming for making high-quality realistic models.
Using simulation to guide the drafting process can speed up the design and production of 3D-printed nanostructures, reduce errors, and even make it possible to scale up the structures. Oak Ridge National Laboratory has developed a model that does this.
