Advancements in 3D Printing

The process of 3D printing has been proven to be useful for various situations throughout society. We even have our own 3D printer located in the physics lab to expose students to the possibilities of this process. The concept serves as a beneficial way of reducing waste in production, creating products at lower costs, as well as creating more intricate designs in production. The only flaws within the operation of 3D printing are the materials themselves and the time required for operation. Many 3D printers do not utilize materials that are capable of withstanding the stress, and the creation itself requires hours upon hours of printing. The capabilities of standard 3D printers are not efficient enough for usage within manufacturing and other industrial processes.
MIT, the Massachusetts Institute of Technology, has developed a 3D printer that is capable of producing objects within minutes while utilizing stronger, more durable materials. The object is printed inside a container of gel which serves as a constant support of the filament used for printing. It is not necessary to allow the filament to cool in order to form support or structure for the object. Eliminating the effects of gravity, the gel allows the printer to perform at much higher rates while maintaining the quality of the object itself. This type of printing allows for more efficient production and, therefore, it is possible to utilize this method in various other ways.
3D Gel Printing 
When printing at higher speeds such as the gel printer pictured above, standard 3D printers lose the accuracy and precision of the printing itself and, therefore, the product is not as precise or sturdy as it would normally be. One project that would have normally take over fifty hours with a standard 3D printer was completed in just ten minutes using this concept of constant gel support. This is also not the first time the engineers of MIT have created a new and groundbreaking process of 3D printing. In 2015, the departments of MIT created a printer that was able to utilize glass, producing amazing sculptures and light fixtures.
3D Glass Printing
The usage of 3D printing creates a waste-free production process; this provides an environmentally friendly operation as well as a cheaper means of fabrication. These innovations within the 3D printing world open new possibilities for various industries and those looking to incorporate 3D printing into manufacturing.

Physics of Sound Dampeners and Active Noise Cancellation

Physics of Sound Dampeners and Active Noise Cancellation Sound dampening foam panels in a recording studio. ANC headphones worn by pilots and/or passengers in consumer aviation aircraft.  Acoustic treatment of soundscapes has grown alongside the sound production industry. Whether through absorption panels, diffusors and cloud panels to treat a space or headphones placed directly over the ears of listeners, acoustic treatment comes in many forms. Environments are treated acoustically to absorb excess sound to prevent sound levels from crossing a threshold above which the desired goal cannot be had. Before getting into sound dampening, we must discuss sound. Sound is produced when an object vibrates (a form of oscillation) and temporarily displaces nearby air molecules causing a wave effect as the displaced molecules collide with their neighboring molecules. Sound waves are fluctuations in pressure as the initial displacement of molecules experiences collisions that in ...

Large Hadron Collider

The Large Hadron Collider (LHC) is the world’s largest and most powerful particle accelerator. The LHC is the largest machine in the world. It took thousands of scientists, engineers and technicians decades to plan and build, and it continues to operate at the very boundaries of scientific knowledge. It first started up on 10 September 2008, and remains the latest addition to CERN’s accelerator complex. The LHC consists of a 27-kilometre ring of superconducting magnets with a number of accelerating structures to boost the energy of the particles along the way. Map of LHC (located in Geneva, Switzerland) Thousands of magnets of different varieties and sizes are used to direct the beams around the accelerator.  Just prior to collision, another type of magnet is used to "squeeze" the particles closer together to increase the chances of collisions. The particles are so tiny that the task of making them collide is akin to firing two needles 10 kilometres apart with suc...

Aerodynamics of a Golf Ball

One may wonder how a small golf ball can travel at incredibly high speeds for such long distances.  While the swing of the club is a major component, the structure of the golf ball is quite important.  Unlike a baseball or tennis ball, a golf ball has dimples all over it (usually 336 dimples).  These dimples allow the golf ball to travel without facing much air resistance.  This diagram shows how air travels around the golf ball. The dimples on the golf ball also prevent drag that would occur in the wake region, resulting in further distance.  Also due to the contact with the club during the swing, the golf ball has backspin during its entire flight.  This diagram shows the motion of the golf ball mid flight with the lift force of F. There are hundreds of different types of golf balls that a player can choose.  Some show little affect to a player's game while others can alter their performance completely.  Personally, I prefer Callaway Supers...
