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 ...
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 The two proposed rules that were just withdrawn would have: Designated as ‘chemicals of concern’ three classes of chemicals for which evidence is more than sufficient to warrant such a designation: bisphenol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, ...
