small fan that cools the plastic as it comes out from the nib. This pen has a metal tip as hot as 270 degree C. Acrylonitrile butadiene styrene (ABS) ABS is the combination of butadiene, styrene, and acrylonitrile. Synthetic monomer acrylonitrile is produced from ammonia and propylene. Butadiene is a petroleum hydrocarbon obtained from the C4 fraction of steam cracking. Styrene monomer is made by dehydrogenation of ethyl benzene — a hydrocarbon obtained in the reaction of ethylene and benzene
The Ultimate Guide To The 3D Printer Filament What is 3D Printing? Technology has developed to such an extent that we can now manufacture products, previously only possible with expensive machinery, practically right in our living rooms. One such approach is the ability to use a special machine called the 3D printer or the 3D printing machine to create three dimensional objects, by means of an additive process. Whereas traditional machining techniques such as cutting, drilling and milling uses a
Still in use today to complete the electronic 'handshake' To transmit files for the printing of 3D objects. The 3D printer The 3D printer is a method of putting a 2D image on a 3D surface. So Basically The 3D printer take a plastic ABS (Acrylonitrile butadiene styrene) and PLA (Polylactic acid) And heats it up really hot and extrudes it on to the sulfas of the 3D printer. To get the thing you want i...
A year and a half ago, I attended a National Rifle Association (N.R.A) Basic Rifle Course. I, had a blast due to the fact I was the only student to show up. I, met with the owner of Zombie Combat Dive Team and learned about 30 different weapons in three days. One of the coolest weapons that I, played with in class was the AR-7. Although intended for use in the U.S. Air Force, the AR-7, originally designed by Eugene Stoner was not adopted. Henry U.S. Air Force Survival Rifle, is a semi-automatic
opaque materials. Some plastic materials have light transmission properties between transparent and opaque. These are called translucent. B. Papers 1. Definitions a. A material made of cellulose pulp, derived mainly from wood, rags, and certain grasses, processed into flexible sheets or rolls by deposit from an aqueous suspension, and used chiefly for writing, printing, drawing, wrapping, and covering walls. b.

FOAM MOLDING: Introducing: Definition: ''Any polymer process which gives a partly or fully foamed product.” (Science dictionary) Foam molding is a manufacturing process that creates parts of a product and artefact made out of foam. The foam molding process consist of mixing foaming agent and base resin in melted polymer, creating a mixture that will be injected into a mold, that will solidify and become a part or an object. History: In 1872 the American inventors John Wesley Hyatt and his brother
The museum of action figures and other amazing toys, will feature thousands of actions figures for guests of all ages. Action figures represent an amazing part of pop culture, thousands of people throughout the world decorate their homes with action figures. Action figures have been around since the 1960’s and they have a very interesting story of development. The story begins with the creation of the Barbie doll, and it was immediately popular and there was a problem there were no toys like Barbie

BOOMERANG INTRODUCTION A boomerang is an aerodynamically shaped object designed to fly smoothly through the air when thrown by hand and which follows a circular flight path that returns it to the thrower. Shapes vary from V-shaped to irregular shapes or with more than two arms. Two design components are the essential features which gives boomerang the capability of circular flight. One is the arrangement of the arms, and the other is the airfoil profile shape that allows the arms into wings.
The Blocks of Lego Introduction Some people have wondered how Lego has been going strong for the past 80 years. At the beginning Lego bricks just seemed like another invention that would fail within 10 years, but some people are surprised to see it is worth over $5 billion today. Though Lego has a ton of sets, Lego has an amazing history that will keep on going and still people just neglect it. Lego The beginning. At the start of the company Lego made wood toys until they had an idea to use plastic
3D Printing: The weapon to save or kill? People nowadays might get the impression that the 3D printing technology is a relatively new concept in our daily life. However, 3D printing technology is invented and utilized in many fields such as creating human organs in healthcare, building architectural models in engineering, even forming components that can be used in aeronautic fields long ago. Since Charles W. Hull has invented the 3D printing technology in the 1980s, scientists, engineers, and even

Arthur couldn't believe the things Morgana could guilt him into doing. Attending a nerd convention as a full-fledged participant really pushed the bounds of what a brother should be expected to do for his sister. Sure, Mordred had had a tragic accident with a butter knife—which may have pleased Arthur to no end—but couldn't she have gone alone? It was just a LEGO con, not a formal wedding where a plus one was a must. What if someone recognised him? He’d never live it down. Set up was on Thursday
Methyl ethyl ketone is one of the top 100 chemicals produced worldwide due to its high demand and versatile end use. This paper will analyze and compare the production processes of methyl ethyl ketone using patent protected methods of two of the industry’s chemical production leaders, Maruzen Petrochemical Co. and ExxonMobil Corp. The analysis of the two methyl ethyl ketone production methods will enable us to bring to light the evolution of the production process over time and the impact which these
The history behind Lego’s is an interesting story of how they came to be. The Lego was a great idea. The Lego is a fun, imaginative, creative, and educational toy! The story behind these amazing toys is interesting! The Lego goes way back to the great depression too! These bricks are cool to play with! The Lego is a plastic building brick. It was made by Ole Kirk Christiansen in Denmark. The first Legos were actually plastic but had to go back to wood because, the people did not like them. But lets
5.7. Name the four alloying elements that have the greatest effect on the properties of steels. Boron improves harden ability, without the loss of (or even with some improvement in) mach inability and formability. Calcium deoxidizes steels, improves toughness, and may improve formability and merchantability. Carbon improves harden ability, strength, hardness, and wear resistance; it reduces ductility, weldability, and toughness. Cerium controls the shape of inclusions and improves toughness in
Lego is made of a plastic called acrylonitrile butadiene styrene (ABS). It is very hard and is what makes Lego very hurtful to step on. The elements that make up ABS is carbon, hydrogen, and nitrogen. Carbon is one of the most essential for living organisms as it forms significant compounds. Carbon
The History of Water Pipes The earliest known evidence of a pipe being used for plumbing was found in Mesopotamia it is estimated to have been made around 3000 BC. The pipes were made from clay mixed with short lengths of straw. This was the first type of pipe to be used to transport water from different places. Both brass and copper pipes have been found in Egypt believed to have been constructed close to 2500 BC. The Romans used lead pipes, extensive use of lead pipe by joining sheets of lead into

Planned obsolescence, according to the Collins English Dictionary, is “the policy of deliberately limiting the life of a product in order to encourage the purchaser to replace it.” Planned obsolescence is the idea that a product is designed to fail, or fall out of style, rather than being designed for longevity and durability (Hindle; Landes). Planned obsolescence has occurred in many industries such as the textile and automobile industries (Hindle; Landes). Items such as dresswear and cars become
