• Adds material layer by layer until printing is finished.

• Allows for complex and intricate designs.

3D Printing

• A method of Additive Manufacturing that adds material to an object layer by layer to create the final product.

  • The Future Of 3D Printing In The Medical Industry

    2308 Words  | 5 Pages

    3D printing has the potential to revolutionize the way we make almost everything. 3D printing was invented in the mid 1980s and was initially known as additive manufacturing. It consists of the fabrication of products through the use of printers which either employ lasers to burn materials (sintering) or place layer upon layer of material (known as stereolithography), eventually resulting in a finished item. Unlike the traditional manufacturing process, which involves milling, drilling, grinding or forging molded items to make the final product, 3D printing “forms” the product layer by layer. There are many different technological variants but almost every existing, 3D printing machine functions in a similar way: a 3D computer-aided engineering (CAD) file is sliced into a series of 2D planar sections and these are deposited by the printer, one above the other, to construct the part.

  • Pros And Cons Of 3d Printing

    840 Words  | 2 Pages

    The way 3D printing works is by taking virtual designs from a special computer aided design or modeling software and “splits” them into separate cross-sections for the machine to use as a guide. The printer then lays down successive layers of the liquid or powdered material required (metal, plastic, paper, ceramics etc.) and eventually builds the model through these series of cross sections, creating the object desired. This printing layer by layer slowly develops the object.

  • The Pros And Cons Of Human Regeneration

    This will even be further refined and we will simply print out replacement parts as needed using a modified 3-d printer similar to what we have today. Whether printed or grown this advancement will have the potential to extended human life well beyond what we currently think the limits are. The pros for this advancement would be simply that what we consider life altering diseases or accidents would simply be a temporary condition until replacement parts are either printed or grown and then used to replace the defective areas. This has a clear potential to end several common modern conditions and allow people a normal life beyond what we can manage today. Cons to this advancement are numerous but the most apparent is when we combine genetic manipulation and this technology we can produce genetically superior body parts. Thus, the human condition we have at birth will be thrown out and replaced with something beyond our imagination. This also has a con in that as with genetic manipulation towards a superior human if someone had an ulterior motive they could in fact insert a type of gene marker that if activated could potentially kill the recipient or be used to control a person through either overt blackmail or covert control. AS is the case with all advancements we have looked at thus far we would need to manage this one and ensure the safety of anything being used to replace a body part is not modified to the detriment of the person receiving the replacement

  • The Dangers of 3D Printing

    1282 Words  | 3 Pages

    Is the creation of human organs via 3D printing morally acceptable? How could a printer cause one to lose his or her life? How do 3D printers attack the environment that is so sacredly protected? What will happen to the economy if everyone is able to own these mini factories? Printers allow for easier sharing of computer data and other visual objects. However, in this rapidly accelerating technology boom, a new type of printer has been created. This new printer has the ability to print three-dimensional objects and construction parts. This has revolutionized the modern age by allowing the ease and freedom of production to be done at one’s home. Unfortunately, this new idea of 3D printing also allows anyone to produce almost anything in his or her home and use it for whatever he or she wishes. Although 3D printing has medical advantages, 3D printing should not be allowed because it leads to playing God, it gives citizens the ability to print weapons, it is not environmentally friendly, and it hurts the economy.

  • Abrasive Operations: The Honing Process Of The Machining Process

    727 Words  | 2 Pages

    As the name of this group of abrasive operations suggests, their objective is to achieve superior surface finish up to mirror-like finishing and very close dimensional precision. The finishing operations are assigned as the last operations in the single part production cycle usually after the conventional or abrasive machining operations, but also after net shape processes such as powder metallurgy, cold flashless forging, etc. The finishing processes discussed in this section include honing, lapping, superfinishing, polishing, and buffing. Honing is a finishing process performed by a honing tool, which contains a set of three to a dozen and more bonded abrasive sticks. The sticks are equally spaced about the periphery of the honing tool. They

    In order to analyze its pros and cons, we need to know the technology first. As one of the advertisements states, “3D Printing: Make anything you want”. Of course, with the current maturity of this technology, this line exaggerates its effects, yet it certainly has a point. 3D printing is “a mechanical process whereby solid objects are created by ‘printing’ successive layers of material to replicate a shape modeled on a computer.

  • Trope Vs Pirate

    My aim is to examine certain past cases where a party claimed that their intellectual property was used without consent. Because most things are not black or white, rather a spectrum of grays, patents surely produce positive and negative outcomes. They can potentially block certain individuals’ access to certain essentials who might desperately need them. In economic terms, a deadweight loss exists might exist in economies where patents are implemented by a government. This is a controversial topic, since the firm or individual attempting to defend the patent in question can potentially lose profits due to the copyright infringement. 3D Printing: Cultural Property as Intellectual Property, written by Charles Croning will be one of my essential sources for my paper. His focuses on “how we perceive tangible works of cultural property, and how we resolve disputes over their ownership.” I will investigate the outcome of these cases to a higher degree, as well as, analyze the claims of the opposing

    The 3D printing of biological materials could potentially create an efficient alternative for patients who may be waiting to receive an organ as well as creating a new advancement while facilitating and increasing the success rate of surgeries performed by doctors. Bio-printing is the 3D printing of biological materials such as human organs and tissue by using cells from the individual’s body as well as other materials such as metals, plastic, powders, and liquids to make up an organ that will eventually take the place of the original organ, also known as stereolithography. The process Stereolithography was first seen in 1983, when invented by Charles Hull and several colleagues. The cost of Bio-printers can range from 10,000

    4D printing offers the ability to make things that literally pull themselves together. The technology could also create objects that last longer than their 3D-printed counterparts and adapt to specific conditions on command. 4D printing is relay about using a 3d printer to print self requfingering programmable material. For example you have a non-living object that can change his shape and behavior over time kind like a robot but no microprocessors, in fact something that looks like a plastic. Skylar Tibet’s, the man who came up with whole idea has gone even fodder; he created a programmable sheet material. It look like a plastic, that in combination with the water it could change the shape in the cube. And the cube is just a beginning. It will be a million of shapes. It could be so useful, not just on the Earth but in the orbit as well. This idea could change the world, and living on it. Imagine you could just print your furniture. An...
