3D printing is making it easier and faster to produce complex items with numerous moving parts with elaborate designs and is affordable enough to have at home. Additive manufacturing is a category of manufacturing technology that includes 3D printing according to its guidelines. Additive manufacturing is creating an item by adding a substance layer by layer to the item you are creating it into. Additive manufacturing has many aliases you may have come across, such as stereolithography, 3D layering, and 3D printing. Just as layered water droplets create icicle-like mineral deposits in caves, 3D printing performs a similar process in which it adds layer after layer of material to its base. In contrast, 3D printing is a faster process and hides a programmed design provided by the computer software. The computer instructs the 3D printer to add each new layer in a precise cross-section of the final object. 3D printing is based on the knowledge of inkjet and has been accessible for 2D printing since the 1960s. The nozzles on a 2D printer move back and forth dispensing a fluid. Instead, instead of nozzle movement, the print surface moves up and down in opposition to flat motions. Additionally, these printers use no ink; they dispense thick waxes and plastic polymers, which solidify to form each new cross-section of the robust 3D object. 3D printing was modeled after the generation of 2D printers that pioneered this exciting new technology. Binder printing is a major competitor and has some advantages over direct 3D printing. For example, it tends to be faster than direct printing because less material is applied through the nozzles. Plus, another benefit is that you can incorporate a wider variety of materials into the pro...... middle of paper ......eos on how to make them. The first models were not fully developed to what they are now. Some 3D printed guns that can work just as well as a real gun. Having access to this type of information on the Internet can potentially cause serious harm. Weapons could now be sold without serial numbers and have a high presence on the black market. Now anyone with access to a 3D printer can print a gun in their kitchen. This raised eyebrows and the government immediately removed it from the Internet once it was published, but the gun design remained on the Internet for three days. Which is enough for something to go viral and others to copy the design and post it elsewhere. A few days later the files spread to various web pages where they were downloaded over 100,000 times. How can the government keep up with the threats? As of now it's a cat and mouse game.
