If you polled gun owners, you would probably find that most say one of the most tedious parts of owning a gun is cleaning it. The traditional way involves messy and smelly chemicals and oils, taking apart the weapon, and painstaking scrubbing at each individual part and the inside of the barrel with wire brushes.

Advances in Spinal Implants
3D printing, also known as additive manufacturing, has ushered in advancements across many industries, including the medical industry. One area, in particular, that has been impacted is the manufacture of medical implants. Additive manufacturing has allowed implants to be created that conform precisely to each patient’s anatomy, revolutionizing the industry. One area of implants which has been especially affected is in the treatment of spinal conditions. Not only can spinal implants that are precisely designed to fit each individual patient’s anatomy be fabricated, but advanced medical-grade 3D printing can use cutting-edge materials to create porous structures that encourage full integration with the human body. The goal of using these porous structures is an attempt to simulate the architectural properties of bone, while the material still offers the strength and durability of a medical implant.

For many home and business owners, a fire or flood are the worst possible nightmares. These disasters mean the potential loss of valuable items, some of which are rare and irreplaceable. After a fire, soot and smoke damage can cover household and business items. Water from the fire department’s efforts can also cause lasting damage to objects. In the case of flooding, there is water damage, of course, in addition to mold and mildew damage that can occur after the flood waters recede. In the past, it was often better to simply get rid of most damaged objects rather than try to clean them. Even in the case of cleaning efforts, the end results were not always desirable, and were both expensive and time consuming. [Read more…]
3D printing, otherwise known as “additive manufacturing,” involves “printing” a solid object using a computer-guided device which extrudes a substrate to form the object. This new process has come into its own over the last decade and is now being used for a myriad of applications across many industries, including the aerospace industry. Here are a few of the ways the aerospace industry benefits from 3D printing: [Read more…]
Sound travels in waves. Imagine that if you could see sound waves–they might look something like ocean waves. Then, visualize those waves or ripples passing by an object, such as a piling standing in the water. The number of waves that pass by the piling per second would be the frequency. Frequency is usually measured by “hertz,” a unit of measurement which corresponds to one cycle per second. High-frequency sound waves such as ultrasonic waves are measured in thousands of cycles per second, or kilohertz (kHz). Ultrasound starts at the upper limit of human hearing, approximately 20 kHz. Many animals can hear above this range, such as dogs and bats, and some, such as dolphins, communicate using it.
