Genetic modification moves to a new level with a technology to produce bioacrylic under development by OPX Biotechnologies, Boulder, CO. Since beginning pilot scale development in 2009, the company says it has reduced bioacrylic production cost by 85 percent. The target price is $0.50 per pound.
Its proprietary technology, called EDGE (Efficiency Directed Genome Engineering), is said to rapidly develop a microbe and bioprocess. OPX generates mutations that track genes responsible for performance changes. OPX researchers then select genetic changes from a variety of randomly created strains and combine them. OPX claims its technology is 1,000 to 5,000 times faster than conventional genetic engineering methods. Biomass and other feedstocks are used.
OPX has retained Merrick & Company to design its demonstration and commercial manufacturing plants, which are scheduled to become operational in 2011 and 2013, respectively.
As the 3D printing and overall additive manufacturing ecosystem grows, standards and guidelines from standards bodies and government organizations are increasing. Multiple players with multiple needs are also driving the role of 3DP and AM as enabling technologies for distributed manufacturing.
A growing though not-so-obvious role for 3D printing, 4D printing, and overall additive manufacturing is their use in fabricating new materials and enabling new or improved manufacturing and assembly processes. Individual engineers, OEMs, university labs, and others are reinventing the technology to suit their own needs.
For vehicles to meet the 2025 Corporate Average Fuel Economy (CAFE) standards, three things must happen: customers must look beyond the data sheet and engage materials supplier earlier, and new integrated multi-materials are needed to make step-change improvements.
3D printing, 4D printing, and various types of additive manufacturing (AM) will get even bigger in 2015. We're not talking about consumer use, which gets most of the attention, but processes and technologies that will affect how design engineers design products and how manufacturing engineers make them. For now, the biggest industries are still aerospace and medical, while automotive and architecture continue to grow.
More and more -- that's what we'll see from plastics and composites in 2015, more types of plastics and more ways they can be used. Two of the fastest-growing uses will be automotive parts, plus medical implants and devices. New types of plastics will include biodegradable materials, plastics that can be easily recycled, and some that do both.
