3-D Printing Outpaces the FDA
By Alan Kelsky
The watchdog in the United States for medical devices is the esteemed government agency known as the Food and Drug Administration. The FDA, however, is flummoxed about how to handle 3-D printing of medical devices. It's not that the FDA has lost its smarts, it's just that the 3-D printing technology has spread so quickly, they are behind the curve. In late 2013, the FDA announced that it planned to publish approved guidance for this new technology by 2015. At this point, it seems unlikely that the agency will make its self-imposed deadline.

SPE HIGHLIGHTS


Real-Time Measurement of Local Permeability During Resin Transfer Molding
SPE Plastics Research Online
Resin transfer molding (RTM) is a popular manufacturing technique for producing composite materials whereby thermosetting resin is injected into a mold to impregnate the fiber preform. In RTM processes, permeability of fiber reinforcements is a critical property that affects the filling behavior of resin. In general, this parameter is nonuniform across the preform owing to fiber deformation and mold misfit. Consequently, real-time measurement of local permeability during RTM is crucial for both product quality control and numerical process simulation.

Modeling Multilayer Film Co-Extrusion
SPE Plastics Research Online
When two or more separately extruded polymer melt streams come together to form a single stratified structure with multiple layers, the resulting multilayer polymer film can combine the properties of different polymers into a single structure with improved features. During co-extrusion, the different melt layers must remain distinct but well bonded (or compatible) when in contact. For this, many factors must be considered, including the co-extrusion hardware and the flow properties of the polymer melts involved.

    Advancing Plastic Thermoforming Technologies — Let's Shape Up
    By Don Rosato, Aldo Crugnola and Nick Schott
    The thermoforming process typically consists of heating thermoplastic sheet, film or profile to its softening point and then forcing the hot, flexible material against the contours of a mold in three ways: pneumatic means, mechanical means, or a combination of pneumatic and mechanical means. Recent advances in thermoforming have come in both software and machinery. For example, injection molders are not the only plastic processors that can benefit from process simulation software.

    The 1st Entirely Plant-Based Plastic Milk Carton is Now on Shelves
    Gizmodo
    In January, anyone in Finland who buys a lactose-free skimmed milk drink called Eila at the supermarket will be buying the world's first carton made entirely out of plant-based plastics — right down to the cap. Tetra Pak, the packaging giant that produced the carton, is very proud of it. The company calls it "the world's first fully renewable carton package," and the key word here is renewable: The raw materials — the source — of the plastic in the carton came from plant-based sources, rather than petroleum-based ones.

    BPA Plastics Chemical Poses No Health Risk, says European Watchdog
    Reuters
    The chemical bisphenol A, used to stiffen some plastic food containers, poses no health risk to consumers of any age, including unborn children, at current levels of exposure, Europe's food safety watchdog recently said. Some studies have suggested possible links to everything from cancer to heart disease to infertility to kidney and liver problems, prompting European Food Safety Authority to re-evaluate the potential risks of BPA.

    A Look at Plastic Film Recycling
    Plastics Engineering
    In 1996, the American Plastics Council (the predecessor to today's Plastics Division of the American Chemistry Council) commissioned a whitepaper on plastic film. In its paper, the environmental consulting firm Headley Pratt noted that, compared to alternatives, commonly used plastic film typically: Uses much less material to package products; takes less energy to produce; takes up less space in shipment, storage, and at retail; and reduces environmental impacts of transportation.

    Hierarchically Porous Polymers with Fast Absorption
    Phys.org
    A research team at KAIST has developed a method to form micropores of less than 2 nanometers within porous polymers where 10 nanometers long mesopores connect like a net. The advantage of the porous polymers is fast absorption of molecules. Porous polymers with micropores of less than 2 nanometers, like a zeolite, have a large surface area. They are used as a means to store hydrogen-based molecules or as a catalytic support that can be used as a surface to convert a material into a desired form.

    BPF Talks Tough on Possible Levy Exemption for Biodegradable Bags
    Plastics & Rubber Weekly Magazine
    The British Plastics Federation is ramping up the pressure on the government over concerns that ministers might look to exempt biodegradable plastic bags from the single-use bag levy in England. Any exemption from the levy, which is due to be debated shortly by MPs and Peers and come into force in England in October, would be contrary to the recommendations of the government's own Environmental Audit Committee, the BPF said. It would also be opposed by "virtually all organizations within the U.K. plastics sector," according to Roger Baynham, chairman of the trade body’s recycling group.

    Chinese Doctors Build 3-D Printed Model to Repair a Shattered Shoulder
    3DPrint.com
    Chinese doctors and technicians have used 3-D printing to treat an injury referred to as "floating shoulder," a condition so dangerous to a patient that it often results in death. An 18-year-old male patient badly injured his shoulder in a traffic accident. An anteroposterior X-ray was performed and the patient was diagnosed with acromial fracture, scapular fracture, and displaced clavicle by the emergency doctor. Based on the patient’s CT data, the fracture model was built with a digital orthopedic workstation called Mimics from Materialise.

    A team led by MIT's Edward Boyden has found a way to expand biological tissue to several times its original size – giving researchers a more detailed look than ever at microscopic structures within the body. And as silly as it sounds, the substance they've used for this upsizing is the same polymer that makes baby diapers swell up when they get wet.

    Manufacturing executives like what they are seeing on their balance sheets, are increasingly confident about the U.S. economy and plan to do more hiring and operational spending in the year ahead, a new survey from PwC US reports. In its Q4 2014 Manufacturing Barometer, PwC found that 68 percent of senior manufacturing executives were optimistic about the U.S. economy, up from 57 percent in the third quarter. Optimism about the global economy also improved, to 38 percent from 30 percent in the last quarter.

    Nanotechnology Changes Behavior of Materials

    One of the reasons solar cells are not used more widely is cost — the materials used to make them most efficient are expensive. Engineers are exploring ways to print solar cells from inks, but the devices don't work as well. Elijah Thimsen, Ph.D., assistant professor of energy, environmental & chemical engineering in the School of Engineering & Applied Science at Washington University in St. Louis, and a team of engineers at the University of Minnesota have developed a technique to increase the performance and electrical conductivity of thin films that make up these materials using nanotechnology.
