3d Printing Or Additive Manufacturing

3D printing or additive manufacturing is a process of making three-dimensional solid objects from a digital design. The creation of a 3D printed object is achieved using additive processes. In an additive process the desired object is created by laying down successive layers of material (usually molten alloy or plastics) until the entire object is formed. Each of these layers can be seen as a thinly sliced horizontal cross-section of the eventual object.

The process starts with a concept or idea.(Mashable) The first stage of 3D printing is planning out this concept with either computer aided

The drawing software used to designate slices into the scanned hand was 'Meshmixer' and 'Autodesk 123D Make'. The materials I used to make the replica were cardboard.

Imagine how a brick layer builds a wall. He lays down bricks one row at a time starting with the bottom row. After finishing the topmost row, the wall

It gives people power to create anything through knowledge and technology. According to Eddie Krassenstein, a co-founder and director of the largest 3D printing news publications on the web gave background information, on the history of 3D printers. The first 3D printer took 6-8 weeks to print an object, was invented by Charles Hull on March 9, 1983 (Eddie Krassenstein). With the advancement of technology, 3D printers can now printer within hours. As reported by, Robert Green a cadalyst author, a CAD programmer and an expert in CAD management expounds that, Three-dimensional printers are fast and easy to use nowadays. The printers allows people to print within hours instead of waiting weeks for your object to arrive. 3D printers use “plastics, nylon, rubber like materials, etc.” (Green 2). Mashable, a YouTube channel that uploads videos of the latest innovation in technology, global news, entertainment, and more. When we have downloaded the software into the computer and have a “blueprint or downloaded a design from thingiverse, then you can print” (Mashable). Thingiverse is a website where anyone can download free drawings and blueprints to various 3D objects and print them three dimensionally. After all the measurements of the object is correct and the design complete. You can send it or transfer it to the printer to print

There is little of what a 3D printer can’t create, as they have been used to create robots, prosthetics limbs, shoes, and musical instruments. After the blueprint is created then it has to be imported, depending on the file the 3D printer accepts. In my case we used the Dremel Digilab 3D45 3D Printer. The printer is very large for its size around 15.9 by 20.2 by 16 inches. This is a closed-frame printer, with a clear plastic door in front that opens outward, and a clear lid on top that swings upward to open. This permits easy access to the print bed when needed, and safety when a print job is in progress. Also the glass build plate is heated up to 100°C and 0.4mm steel nozzle heated up to 280°C. Also it uses filament, specifically a polylactic acid filament and can use up to 11 different colors and Eco-ABS which is a modified filament, and the one I used for printing. With the printer they include the Idea Builder with heated build plate to print Nylon, ECO ABS, PETG, PLA at 50 micron resolution. The printer uses Dremel Cloud to upload projects, which accepts them in STL format. STL files describe only the surface geometry of a three-dimensional object without any representation of color, texture or other common CAD model attributes and is used by all 3D printers. The reason I used Dremel Cloud is because it is the only program compatible with the printer and helps

3D printing can create object in any shape imaginable thanks to the two dozen printing processes. 3D printing first made its appearance in the early 1980’s by Charles Hull. In 1988, Hull founded the company 3D Systems, which developed the first commercially available 3D printer. Hull set great footsteps for future generations to follow. As known, 3D printing has been used in manufacturing industries for decades. Three dimensional printing can largely benefit healthcare and medical uses due to the customization, cost efficiency, and the rapid productivity. Customization is a great advantage to 3D printing because it allows for custom made medical products and equipment that is prepared for each body and fixture. The time

Have you ever lost a limb? Have you ever needed a new car part? If so, the marvel of 3D printing can deliver these things. The future has truly arrived today, almost any object we can think of can become reality through 3D printing. 3D printing is the process of making a physical object from a digital model by layering a material until it forms the object. 3D printing shows a lot of potential for both recreational and practical uses, and I believe will help shape the future of technology.

To start off with a basic definition a 3D printer is a machine ranging in size from a pen to that of a tank (http://www.dailymail.co.uk/sciencetech/article-2697306/Oar-Fully-functioning-plastic-boat-created-using-worlds-biggest-3D-printer.html). They create the desired design by continously spraying or to a surgical precision laying layers of material on top of each other layer to form the design that was created through one of the many programs made to create 3D printer designs. 3D printers can use a multitude of sources to create their three dimensional final products. These sources can include but are not limited to plastic polymers, titanium, aluminum, iron, steel, and almost any ductile metal or propane product that can be heated and placed without forming into a gas or melting to a point of no return. Of course these aren’t just typical polymers or metals they have been mixed with other certain chemicals and materials to give the materials new found properties. The cost of these 3D printers can be anywhere from $140 dollars all the way up to $846,000 (3ders.org). These are just the consumer models! Take a second to imagine the industrial and prototype models which are even bigger and more complex. When making the product the 3D printer creates it in a chamber where an arm like machine continuously lays material and forms the

3D printing technologies are changing the way we produce objects. 3D printing is part of a process known as an additive manufacturing, where an object is created by adding layer by layer. Additive manufacturing allows designers create complex parts for machines.

From car models to food and clothing, 3D printing will allow quick designing and modelling. 3D printers do save a lot of time and money, as it is entirely done through software tools and brings out the automated result, helping manufacturers to work within the deadline.

Why go to stores and spend lots of money buying toys, jewelry, cups and many other plastic utilities when you can only press one button and print them out for yourself. This futuristic idea is not only innovating the scientific and technological world, but it is also innovating modern day households. The possibilities of 3D printing are extremely captivating, making this one of the most exciting innovations in recent times. 3D printing, also known as additive manufacturing, makes three-dimensional solid objects from a digital model or command. To picture how this process works, 3D printers use an additive process, where adding layers of a successive material creates an object. Traditional machines, however, uses a subtractive process by

3D Printing is a unique kind of printing system, which takes a 3D image file and creates a physical 3D image. As I mentioned before 3D files are generated from what is called a .stl file, which is a compressed triangular meshed surface. “These .stl files were originally intended for a rapid prototyping process called Stereolithography, and in the beginning were generated by CAD programs; however, because MRI and CT’s are surface scans, they too can generate a .stl file. These .stl files have become a world standard for exchanging 3D mesh type objects between programs” (McNeel, Sep. 2015, par. 3). Since MRI’s and CT’s can be scanned and converted into stl files it has paved the way into many different aspects of the medical and dental industry for 3D printing. When I say the medical and dental industry I am talking about many different avenues within those industries.

With the very limited supply of organs, 3D printing creates functioning organs without a donation from a living organism. The definition of 3D printing from Charles W. Hull, the inventor of 3D systems, states that “...thin layers of a material that can be cured with ultraviolet light were sequentially printed in layers to form a solid 3D structure” (Murphy & Atala 773). The sheer narrow sheets play a vital role in bioprinting. They allow the printers to develop functional, layering individual cells, proteins, and an extracellular matrix. The three basic types of 3D printing include biomimicry, independent self- assembly, and miniature tissue blocks. The creation of the 3D structure creates all the difference between these types of printing. Three dimensional structure approaches include, creating exact duplicates of the cells and tissues with extensive knowledge, using a developing embryo as a template or using microscopic tissues to assemble into a larger developed tissue (Kalaskar). In other words, all these paths to bioprinting end up with a 3D structure but require different knowledge and materials. They all contain their own sets of challenges.

3D printing is a technology that was invented in the early 1980s by a man named Charles Hull (Ventola, 2014). Since its creation, 3D printing has branched into many different aspects of the world and is being utilized in fields like the automotive industry, medicine and is even being used for everyday purposes. Later on, Charles Hull founded a company called 3D Systems which developed the first ever 3D printer. In 1988, Hull and his company 3D Systems, put forth the first commercially available 3D printer. From this point on, 3D printing would be advanced and evolved to the point where it would have the opportunity to create a revolutionary impact on the world we
