Non-recycled plastics (NRPs), which make up 12.4 percent of municipal solid waste (MSW), have high value as a feedstock for conversion to energy or fuel because of their potentially significant heating value. (Source: Gershman, Brickner & Bratton/US EPA)
That's pretty funny, bobjengr, thanks for the taco-shell story. Making fuel from various types of farm waste and food waste is not a new idea. There's sure a lot of methane and potential methane to go around. And when it comes to agricultural animal waste, these efforts are sorely needed.
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.
Engineers need workhorse materials with beefy mechanical properties for industrial designs made with 3D printing. Very few have been designed from the ground up for additive manufacturing, but that picture is beginning to change.
Focus on Fundamentals consists of 45-minute on-line classes that cover a host of technologies.
You learn without leaving the comfort of your desk. All classes are taught by subject-matter experts and all are archived.
So if you can't attend live, attend at your convenience.
