The Best Light Bulb Moment

wLED light technology has been popping everywhere nowadays. What’s great about this technology is the lifespan which lasts up to 20 years for those that have 5 watts or fewer. Compared to conventional light bulbs which are above 50 watts, LED lights only make use of 10% of the energy that fluorescent and incandescent lights consume.

LED stands for light-emitting diodes which are the main source of light. LED has a longer life and higher energy efficiency, which makes it a little costly to produce as compared to the typical fluorescent and incandescent lamps. But what LED manufacturers and producers always highlight is how the LED produces as much lumen as conventional light bulbs but with lower wattage. Lumens are what manufacturers and producers use to measure the output of brightness. This means that LED bulbs can be as bright as or even be brighter than fluorescent and incandescent light bulbs but because it uses less wattage, it requires less energy.

Lower maintenance is required for LED light since it is enclosed in a plastic lens. Conventional bulbs are usually enclosed in glass or tubes made of glass. And since LED does not make use of mercury or other toxic chemicals, it is safer for the environment, too.

Also, UV rays which are usually found in halogen, fluorescent, and incandescent lights are not found in LED lights which make it a safer option since they will not cause the furnishings and coverings to fade. Because LED lights do not use infrared radiation, they do not create too much heat and are cool to the touch when they are in use.

LED lights can illuminate any size space. There are different types of light bulbs which can be used in different parts of the house. For instance, yellow lights, which are usually dimmer, are better for bedrooms, bathrooms, and hallways. There are soft white bulbs too which are perfect for the kitchen, living rooms or dining areas where a much brighter ambiance is preferred. But LED lights are not just used in households. There are traffic lights, flashlights, and even holiday lights which are beginning to make use of LED technology.

LED lights are becoming widely available nowadays and even big electrical and appliance companies are starting to make use of this brilliant technological advancement. One of the biggest corporations, Toshiba has also joined in the ball game. Toshiba LED bulbs are now available in the market and the consumers who have tried their product are very pleased with their purchase.

Revolutionizing Manufacturing

7g“3D printers”, the term defines itself. The first 3D printer was introduced in 1980 and at that time it was known as the rapid prototyping apparatus. It was named so, as the process was relatively fast and cost effective for creating prototypes. In 1986 the complete patent for the 3D printers was issued to the stereo-lithography apparatus by Chuck Hulls, who later on founded the 3D systems cooperation.

In simple words, a 3D printer creates a three dimensional object by using 3D models of the object to be formed & by using different types of raw material depending upon the type of object to be prepared.

The most common type of 3D printing technique is called stereo-lithography which uses a vat (container) of photo-polymer resin. During the process of manufacturing the liquid polymer is exposed to light, where the UV laser light draws the cross section of material by hardening it, layer by layer and repeats the same process to forma complete 3D structure or a prototype.

The designing process is called bottom up, i.e. pulling the object out of resin. This creates some space for the uncured resin at the bottom of the container which then leaves some scope for the formation of the next layer of the prototype.

Along with stereo-lithography many other 3D printing techniques are incorporated in the field of 3D printing nowadays.

Application Areas:

3D printing can be put to use in various areas such as Food, Manufacturing, Aerospace, Oil and Gas, Pharmaceuticals, Footwear, Medical, Electronics, Toys etc. Since a 3D printer can create three dimensional objects, it can be used in any product manufacturing area.

Industrial Impact:

3D printing might trigger another industrial revolution as it will tremendously affect the manufacturing world, both technically and economically. The concept of ‘Distributed 3D printing manufacturing’ also offers the promise of a lower working capital as it eliminates the need for large stocks of raw materials, semi-manufactured parts and labor costs.

Manufacturing near the point of demand makes the supply chain and logistics very simple and much more efficient, only the raw material needs to be transported. Also the waste product is nearly zero so there is no harmful impact on the environment which has become a great cause of concern in today’s world.

Future Advancement:

Although many advances have already been made in the 3D printing domain and it also seems to be a very advanced piece of technology, but soon 3D printing will become an obsolete concept and would then get replaced by a relatively new concept that is 4D printing.

Although there is very little that the inventors have achieved in the field of programmable matter and 4D printing, a lot of research & innovation is getting carried out. One of the patent documents, US 20150158244 A1, explains the concept of 4D printing in a thorough manner.

4D printing will become the continuation of 3D printing in which an additional ‘time’ dimension will get added in combination with the other 3 dimensions, which are already present and getting used in 3D printing.

The main concept of this technology is that the object which is printed in 3D is capable of transforming into different shapes with time and so, this way, it gets its predetermined shape.

After all many researches have been done and are still happening in the field of 3D printing due to which we can say that 3D printing is a big step in revolutionizing the Manufacturing world.
