From Editorial Desk…..

Dear readers,

MExpress has been a medium to excavate the minds of students. This newsletter aims to a platform for young minds to express their creativity. It offers the reader an encapsulated view of the academic, creative, literary and artistic ventures of the talented team students & lists the achievements of the session.

The latest publication of this newsletter reflects our progress in yet another academic ses-sion, which we have achieved by imparting value based education and conductive environment for overall personality development of students.

Editorial board sincerely acknowledge the contribution of all authors and gratitude

towards the management.

TECHNICAL

Perhaps the best known form of additive manufacturing is fused deposition modeling (FDM), which was invented by Stratasys in the late 1980s. Using the same STL files created by 3D Systems for their stereo lithography system, the fused deposition modeling 3D printer squeezes melted thermoplastics through a small nozzle to create an object.

The process is much like the way you squeeze out toothpaste to cover your toothbrush. By building up layers of melted plastic, the object can be created and rapidly cooled to room temperature in a matter of minutes.

The thermoplastic used in this type of 3D printer is typically sold in spools of thin filament, varying in widths between 1.75 and 3.00 mm. This filament can be made up of acrylonitrile butadiene styrene (ABS) polymer, polylactic acid (PLA) bioplastic, water-soluble polyvinyl alcohol (PVA) for support, nylon, and composite materials. One such experimental wood/plastic composite filament can be sanded and painted like wood, and even given a grain-like pattern by varying the temperature at which it is squeezed out.

APPLICATIONS:

Medical implants

Item personalization

Clothing and textiles

Military fabrication

In space

Material used :

Polylactic acid (PLA)

Acrylonitrile butadiene styrene (ABS)

Polycarbonate (PC)

Polyamides (nylon)

Polyvinyl alcohol (PVA)

High-impact polystyrene (HIPS)

High-density polyethylene (HDPE)

The benefits include:

✓ Flexibility: Individual molds can be re-created as multi-cavity molds

by simply creating multiple copies of the base design several times in

the computer model and then printing a new model, with updates that

improve corner-radius issues or add channels to increase flow efficiency.

✓ Repeatability: As older molds slowly degrade (for example, with the

softening of the sharp edges), new molds can be created — even years

later — with perfect repeatability of the original mold.

✓ Scalability: Digital designs can be printed at any desired scale, allowing the creation of precise duplicates at half scale or double scale — or

duplicates that include specific distortions to facilitate specialized brand identification (or other artistic manipulation of the original image).

The first 3D printer, which used the

stereo lithography technique ,was created

by Charles W. Hull in mid1980s.

1.Indian Railways launches first solar powered train

PAGE 3 W RLD AT NEWS…..

Indian Railways on July 14 launched first solar-powered DEMU (diesel electrical multiple unit) train from the Safdarjung railway station in Delhi. The train will run from Sarai Rohilla in Delhi to Farukh Nagar in Haryana. A total of 16 solar panels, each producing 300 Wp, are fitted in six coaches.The cost of these solar panels, manufactured under 'Make in India' initiative, is Rs 54 lakh. This is the first time in the world that so-lar panels are being used as grid in railways. The train has a power back-up and can run on battery for at least 72 hours.

The railways are planning to introduce nearly 50 more such coaches in the coming days. Solar power would be introduced first in urban trains and later in long-distance trains as well. By saving an estimated 1.2 lakh kilo litre of diesel every year, the railways will be able to pocket Rs 672 crore per year. The solar power will also help in reducing 2.7 lakh tonnes of carbon dioxide emission per year. Railways has plan to generate 1000 MW solar power in the next five years. Steps are being taken to install solar plants at railway building rooftops and level crossings across the country.

2.Drones

Unmanned Aerial Vehicles (UAVs) are aircrafts which are remotely-piloted eliminating the need for a pilot to be on board during a given flight. In the civilian life, drones are a common occurrence and hardly will a week pass before you set your eyes on one. They have an array of applications ranging from being mere hobby gadgets to their increasing use in professional photography and cinematog-raphy, intelligence, mapping, reconnaissance as well as target destination besides being used in rescue missions.

The 96km Kalka-Shimla track is on the heritage list of UNESCO. The train passes through 102 tunnels and 864 bridges is considered as an engineering marvel.
