The Future of 3D Printing and Healthcare

When it comes to 3D printing, the sky is the limit. As 3D printing technology continues to advance, applications can be as far reaching as  airplane  and  automobile parts  to medical devices and even anatomically correct, biocompatible models. Although 3D printing technology is developing at a rapid pace, the technology itself is not new. It emerged in  the 1980s  as a means of creating rapid prototypes. In recent years the applications for 3D printed models have evolved with the available hardware, software, and printable materials. Evolving technology, paired with the creative and innovative minds of scientists, engineers, and physicians, has been the launching pad for developments within 3D printing technology specific to healthcare. One way 3D printing technology is poised to create better patient outcomes is in creating an anatomically and  patient-specific models  to aid in surgery and medical procedures. With the capability to 3D ...

Delivery Truck Redesigned With Lightweight Plastic

United Parcel Service of America, Inc. (UPS) was looking to cut fuel costs for its delivery trucks. The company has a few thousand plug-in electric and natural gas-powered vehicles in its 70,000-plus fleet, but batteries only go so far, and natural gas stations aren’t usually along rural routes.
UPS was looking for a diesel-powered cargo van with increased fuel efficiency that could travel through city and country like the existing van. Turns out that Utilimaster Corp. and Isuzu Commercial Truck were developing just such a truck, reports Rhoda Miel at Plastics News.
Starting in 2008, Utilimaster and Isuzu began work on the Reach in response to customer requests for better fuel mileage. The new vehicle promises to be 35% more fuel-efficient than standard vans, which the designers estimate could save delivery companies $3,000 in fuel per vehicle, per year.
UPS is currently testing modified versions of the Reach, “which has a composite skin, structural plastic floor and roof and injection molded bumpers,” according to Plastics News.
“This was developed from a clean sheet of paper,” said John Knudtson, vice president of product development for Utilimaster told Miel. “The architecture is unique. It doesn’t exist just off the shelf.”

Many delivery trucks have a design traditionally called an aluminum step van because they are made with aluminum body panels that are connected to vertical structural supports. Miel gives more details about how plastics were used in the lighter-weight Reach:
By rethinking the entire vehicle, rather than merely replacing one material for another, Utilimaster was able to eliminate metal supports in favor of a composite body that is molded in color to eliminate the need to touch up paint from scratches.
The floor is a one-piece composite structure with a polyester skin on the top and bottom and a urethane foam core. The PE outer layer also means that the floor will not corrode while the multilayer structure improves acoustic and thermal performance, Knudtson said.
The side walls also are made of PE with a honeycomb inner core, while the front and rear bumpers are made of urethane.
Utilimaster declined to name the plastics suppliers making the Reach’s components. Isuzu makes the chassis and engine and delivers them to Utilimaster, which builds the rest of the vehicle.
UPS spokesman Michael French told Miel that the company will be making a decision about whether or not to order more trucks after the trial period ends in December. The vehicles are currently being road-tested in various climates and terrains, including Roswell, GA, Flint, MI; Albany, NY; Lincoln, NE, and Tucson, AZ.

Phthalates and BPA Regulations: Are We There Yet?

It’s better to be safe than sorry.  But the Environmental Protection Agency  recently withdrew two proposed rules regulating chemicals  that it had developed under authority of the Toxic Substances Control Act (TSCA) and submitted to the White House’s Office of Information in 2010 and 2011.  Dr. Richard Deninson  of the Environmental Defense Fund explains it further: Faced presumably with the reality that OIRA [Office of Information and Regulatory Affairs] was never going to let EPA even propose the rules for public comment, EPA decided to withdraw them.  The two proposed rules that were just withdrawn would have: Designated as ‘chemicals of concern’ three classes of chemicals for which evidence is more than sufficient to warrant such a designation:  bisphenol A (BPA), a category of phthalates, and a category of polybrominated diphenyl ethers (PBDEs).  By listing a chemical as ‘of concern,’ EPA may obtain, and provide to the public, ...

Virginia Tech Students Create Foldable Bike Helmets

Helmets: Something you may have hated with a passion as a child, but your parents made you wear. As adults, one could argue helmet use is pretty divided. If you head down your local bike path or along a neighborhood street, you’ll see a good number of riders not wearing their helmets. Two Virginia Tech students think that’s a problem. Co-founders David Hall and Jordan Klein started  Park & Diamond  and set out to create a safe, compact, and stylish helmet to hopefully convince people to wear them every time they bike. The interest in refining technology to prevent bike related head injuries is  incredibly personal  for the team of innovators, especially for Hall. In 2015 Hall’s younger sister was involved in a bike accident in Philadelphia and remained in a coma for four months. The bicycle crash occurred at the corner of Park Avenue and Diamond Street in Philadelphia—which is reflected in the name of their company. How Helmets Work Just like the...

The Science Behind 4 Of The Greatest Polymers Of All Time

PMMA Applications: Lucite, dentures, aquarium windows Developed in: 1877 Polymethylmethacrylate is a very versatile polymer. If you ever see a clear plastic block, it's probably PMMA. It was first commercialized in the 1930s in Germany, and is now found anywhere one needs clear, strong material. This includes bulletproof "glass" at your favorite corner liquor store and the huge shark tanks at the Monterey Bay Aquarium. But my favorite use of PMMA is in so-called "frozen lightning" or Lichtenberg figure sculpture. Basically, put a chunk of PMMA into an electron accelerator, fire a bunch of electrons into the plastic until it's got about two million volts of charge, then touch the side of the plastic with a bit of wire and watch as bolts of lightning carve tracks inside the clear plastic. Superabsorbers Applications: Diapers Developed in: 1960s Back in the day, diapers were made from cloth. Frequently, those cloth diapers were filled with wads of n...
