Summary
3D printing is termed as additive manufacturing as it refers to the process of printing a three dimensional object of any shape using digital technology. It is called additive manufacturing because the printing is done using layers of materials which are laid down differently…

3D Printing in the world

Download file to see previous pages... This technique is a modern technique which differs in many ways from the machine techniques that were traditionally used. The traditional methods relied on the methods involving removal of materials such as cutting. This is why they were known as subtractive processes whereas 3D printing is known as additive process. The 3D printing uses the digital technology and these printers were initially manufactured by China. These printers came in the late 1980’s and ever since then they have been increasingly used all over the world. In the beginning of the 21st century, as the digital technology became more popular and advanced, the growth in the sales of the 3D printers was greatly observed. The sales of these printers increased in various parts of the world where they were used for new and innovative purposes. Gradually, as the sales and the demand grew, the costs of these printers fell immensely since they were first manufactured. Some of the purposes for which these machines were used were in industrial uses, architecture, jewelry, aerospace, engineering, medical, education, information systems and many others (Griffith, 2012). 3D printing is the technology to create materials and objects using a sequential layers technique. The materials which are produced by using the layering process can be anywhere in the product life cycle. However, the subtractive methods of manufacturing objects can be used as traditional methods in manufacturing. 3D printing was invented by Charles W. Hull (Chuck). In the mid 1980’s when it was invented, it used a stereolithography technique. This technique used a UV laser which was shined in the vat of an ultraviolet-sensitive photopolymer, and then it traced the object so that it was created on the surface. The polymer would solidify wherever it was touched by the beam, and that beam would print the particular object layer by layer as per the instructions fed in the CAD/CAM file through which it is working. CAD file is computer-aided design and CAM is computer-aided manufacturing. Chuck also founded a company which was called 3D Systems. The company made stereolithography machines which expensive machines of over $100,000 used in commercial techniques. 3D Systems is still operating today and now it sells the 3D printers of advanced technology. There is a variety of printers that are manufactured using different advanced technologies ranging from entry-level kits to the advanced commercial systems. The company also provides on-demand services manufacturing parts for business users. Many businesses and industries use the 3D printers and they need the machines to be up to date and maintained. There are many benefits of 3D printing which is why it is immensely used in the world today. Many designers use the 3D printing techniques to rapidly design the concepts and turn them into 3D models or rapid prototyping. It also allows for the rapid design changes which enables the designers to carry out their work rapidly and smoothly using the up to date technologies. The manufacturers are also allowed to produce the products rapidly on demand rather than on large run, which also increases the management of the sufficient amount of inventory and reduces the warehouse space. 3D printing techniques can help the people living in remote locations to fabricate the objects that would be inaccessible to them otherwise. 3D printing must be a onetime cost because once the designers and businesses have bought the machinery for 3D printing; they can save a lot of material and money which is used in subtractive techniques of manufacturing. The material in this technique is drilled, cut and shaved off; hence raw material can be wasted. 3D printing is ...Download file to see next pagesRead More

Use of 3D glasses in cinemas
Although many of these trends have arrived in the more recent years, the use of three-dimensional (3D) glasses in cinemas had been present in the 1950s. Also, such trend is only a recurring gimmick to attract movie goers, not necessarily giving viewers the “perfect” movie experience.
