3D PRINTING
Introduction
3D printing is a process of producing three dimensional object from a specific digital file that’s the reason why 3D printing is often referred to as additive manufacturing.3D printing takes raw materials from biodegradable plastic to nylon then melts it into very thin layers onto a surface and then moves up an prints another layer until the prints are done. This is controlled by a skilled individual using a CAD (Computer Aided Design) software.
In the old days the production of a prototype required a mold were else when a 3D printer is used it is possible to manufacture a prototype without using a mold. This reduces time to create and produce a prototype weeks to days
How it works
There is a number of 3D printers that exist currently, and every printer type uses different material and mechanism but they all have the same basic technique which is to print objects. 3D printers print on objects by spraying on or transferring multiple layers of a material onto a construction platform, starting with the bottom layer.
When printing a 3D object the end-user of the 3D printer must first produce a 3D image of the end product that they want to print by using an application software called computer-assisted design. The CAD software program send the end-user desired object onto hundred or thousand horizontal layers. All the layers are then placed on top of each other in a one-by-one manner until the whole 3D object develops.
3D Technologies
3D printers do not use the same technology to create objects that’s the reason why there are several ways of 3D printing technologies. 3D printing methods include melting or softening material to produce the layers.

• Counterfeiting: The biggest possible disadvantage of 3D printing is counterfeiting or production of "fake" stuff, and the copyright infringement issue arising due to it. This technology makes a manufacturer out of anyone who owns a 3D printer, and gets hold of the blueprint. Thus, it would be very difficult to trace the source of fake items, and copyright holders would have a hard time protecting their rights.
• Size Limitations: At present, 3D printers have limitations when it comes to size of the objects created. However, in the near future, we shall have printers that can even print architectural structures.
• Raw Material Limitations: Currently, 3D printing is viable for items made from a single raw material only. However, the technology of creating stuff using more than one material is being developed, and will soon be a reality.
Some of the issues presented above resulted from inefficiencies in the two distinct processes taking place in the same production facility at Custom Molds, namely the Molds Fabrication process and the Parts Production process (Exhibit 1a and b). The two processes serve different customer needs. Mold fabrication, a skill oriented and craftsman-driven process, requires flexibility and quality. Parts manufacturing, on the other hand, involves a more standardized process that competes on delivery and low cost. The margin for parts is also much smaller.
With the massive rise in the quality, lower prices and availability 3d printers anybody anywhere in the world now has the ability to produce almost anything they like. Websites like https://www.thingiverse.com/ offer millions of models for almost anything someone needs to produce. Websites like https://www.upwork.com offer online consulting for 3d modelers that will design anything you need. Prior to the availability of 3d printers anything that was designed had to be manufactured at professional production facilities at huge costs relative to 3d printing it. 3d Printing lowers the barriers of entry into a market that was previously dominated by a few people because of the cost of prototyping.
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.
Focus shall be on utilizing pre-production tools while developing the prototypes. Actual material, wherever possible, shall be used in the development of prototypes rather than having substituted parts. Make the prototypes as closer as possible to actual outputs.
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
In additive manufacturing, parts are produced by slicing a CAD model into thin layers and then depositing material one layer at a time to create the 3D part. While current methods are very precise and have high resolutions, I have identified 3 main limitations of additive manufacturing.
The process starts with a concept or idea.(Mashable) The first stage of 3D printing is planning out this concept with either computer aided design or animation modeling software. There are tons of programs out there today with these capabilities. Google SketchUp for example is known for being easy to use.(3ders) Using some easy tools that can be learned quickly, edges and faces can come together to make very intricate models. It can even be used with Google Earth. All those models of the world in that software are made in what is basically the same process digitally. Blender is the free 3D creation program that exists for the needs of major operating systems.(3ders) It is a high end software containing features that are much more capable than Google SketchUp. Tinkercad is a newer way of creating designs for 3D printers and works slightly faster than the others.(3ders) Containing only three simple tools, it’s effectiveness for creating models is among the best..
When you are making the prototype as instructed you will need various materials. These materials can vary depending on how you are instructed to do it. However, one way you can make this is by using twelve wooden dowels, eight craft sticks, sixty rubber bands, one wooden
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 normal people were and still are trying to discover more possibility of the usages and changes on this technology. Same as every invention of the new technology, with its undeniable beneficial effects, 3D printing also faces lots of limitations
In present time, if we look closely around everything we visualize: the clothes we wear, the colors of the room in which we find ourselves, the traffic signs, the television etc., everything around us had a process in which made the picture the sign the logo, Film, video, That where Graphic designs, photography, printmaking, computer-aided design and digital art come into play. Printmaking is a mechanical method to reproduce texts and images on paper, cloth or other materials. In its classic form, it consists of applying an ink, usually oily, on metal pieces to transfer it to a paper by pressure. There is a couple of different technique when it comes to printmaking like relief, intaglio, lithography, and serigraphy which matrices included wood
The idea was to improve 3d printer with special technology, a single printer, with multi material features, can transform from any 1D strand into 3d shape, 2d surface into 3d shape or morph from one 3d shape into another. The shape of 3d technology is basic mode for 4d. Objet Connex multi-material technology is an 3D printing important part of his work – and is being used extensively in this new process. The Connex multi material technology allows the researchers to program different material properties into each of the various particles of the designed geometry and harnesses the different water-absorbing properties of the materials to active the self-assembly process. With water as its activation energy, this technique promises new possibilities for embedding programmability and simple decision making into non-electronic based materials.
Imagine printing what ever it is you need from your own office or home. In addition to that, you will have full control customizing the product and the printer will have no difficulties achieving your designs. All you have to buy is the ink and the material additives and the printer will do the rest.
The second way is by using computer aided drafting (CAD) and computer aided manufacturing (CAM) programs on your computer.
The two main ways printers work is either impact or nonimpact. Impact printers have a device that touches the paper and then creates an image while nonimpact does not touch the paper. The type we use most often in our homes is the nonimpact printers; these include the ink-jet and laser printers. The ink-jet printer drops ink from a nozzle onto the paper. The laser printer is a bit more complicated because it uses toner, static electricity, and heat to get the ink where you want it on the paper. This is nice though because it decreases the drying time that may cause ink to smear, especially when you are printing pictures. (Tyson)
