RepRap. What is 3D Printing? An Overview. You’ve heard of 3D printing from newscasters and journalists, astonished at what they’ve witnessed. A machine reminiscent of the Star Trek Replicator, something magical that can create objects out of thin air. It can “print” in plastic, metal, nylon, and over a hundred other materials.
It can be used for making nonsensical little models like the over-printed Yoda, yet it can also print manufacturing prototypes, end user products, quasi-legal guns, aircraft engine parts and even human organs using a person’s own cells. Fantastical? Yes. True? Yes. We live in an age that is witness to what many are calling the Third Industrial Revolution. 3D printing, more professionally called additive manufacturing, moves us away from the Henry Ford era mass production line, and will bring us to a new reality of customizable, one-off production. Need a part for your washing machine? Each of these printed layers is a thinly-sliced, horizontal cross-section of the eventual object.

What is 3D printing? 3D printing is also known as desktop fabrication or additive manufacturing. It is a prototyping process whereby a real object is created from a 3D design. 2. 3D printing technologies There are several different 3D printing technologies. SLS (selective laser sintering), FDM (fused deposition modeling) & SLA (stereolithograhpy) are the most widely used technologies for 3D printing. This video describes how laser-sintering processes melt fine powders, bit by bit, into 3D shapes. This video shows how FDM works. The video below explains the process of Stereolithography (SLA).
Generally, the main considerations are speed, cost of the printed prototype, cost of the 3D printer, choice and cost of materials and color capabilities. 3. October 5, 2011 - Roland DG Corporation introduced the new iModela iM-01. Sep, 2011 - Vienna University of Technology, a smaller, lighter and cheaper printing device has now been developed.

Lindsay France/University Photography Hod Lipson, assistant professor of mechanical and aerospace engineering, right, and engineering graduate student Evan Malone work with a Fab@Home machine in the Computational Synthesis Lab in Upson Hall Feb. 22.
On the stage is a Lego tire duplicated by the Fab@Home. The Altair 8800, introduced in the early 1970s, was the first computer you could build at home from a kit. It was crude, didn't do much, but many historians would say that it launched the desktop computer revolution. Hod Lipson, Cornell assistant professor of mechanical and aerospace engineering, thinks a little machine he calls a Fab@Home may have the same impact. Some day, Lipson believes, every home will have a "fabber," a machine that replicates objects from plans supplied by a computer. Such machines could evolve from the 3-D printers currently used by industrial engineers for "rapid prototyping.

Times are changing and with time definitions of needs are also changing. There were times when necessities were few, with all other things falling into the comfort or luxury zone. With technological advancements and easy availability many luxury items have shifted into the necessary and comfort zone. Take for example 3D printing technology. You see an object on screen and with the help of a 3D printer you can get the very same object without having to purchase it.
It is true that 3D printers are not yet that popular but at the rate at which they are growing, it will not be long before every household also owns a piece. A normal 2D printer can be found in every second home. Same will be the case with this one in due time. Every one has a dream and a fantasy world but not all have the means and ability to bring it to life. With everything being machine made this printer could to some extent take away the pleasure of 3D modeling that many artists excel in.
Fab@Home - Make Anything | Fab@Home. Wiki. RepRap is humanity's first general-purpose self-replicating manufacturing machine. RepRap takes the form of a free desktop 3D printer capable of printing plastic objects. Since many parts of RepRap are made from plastic and RepRap prints those parts, RepRap self-replicates by making a kit of itself - a kit that anyone can assemble given time and materials. It also means that - if you've got a RepRap - you can print lots of useful stuff, and you can print another RepRap for a friend...
RepRap is about making self-replicating machines, and making them freely available for the benefit of everyone. Reprap.org is a community project, which means you are welcome to edit most pages on this site, or better yet, create new pages of your own. RepRap was the first of the low-cost 3D printers, and the RepRap Project started the open-source 3D printer revolution. RepRap was voted the most significant 3D-printed object in 2017.

Rapid prototyping. 3D model slicing 'Rapid prototyping' is a group of techniques used to quickly fabricate a scale model of a physical part or assembly using three-dimensional computer aided design (CAD) data.[1][2] Construction of the part or assembly is usually done using 3D printing or "additive layer manufacturing" technology.[3] The first methods for rapid prototyping became available in the late 1980s and were used to produce models and prototype parts.
Today, they are used for a wide range of applications[4] and are used to manufacture production-quality parts in relatively small numbers if desired without the typical unfavorable short-run economics. This economy has encouraged online service bureaus. Historical surveys of RP technology[2] start with discussions of simulacra production techniques used by 19th-century sculptors.

An ORDbot Quantum 3D printer. 3D printing or additive manufacturing[1] is a process of making a three-dimensional solid object of virtually any shape from a digital model. 3D printing is achieved using an additive process, where successive layers of material are laid down in different shapes.[2] 3D printing is also considered distinct from traditional machining techniques, which mostly rely on the removal of material by methods such as cutting or drilling (subtractive processes). A 3D printer is a limited type of industrial robot that is capable of carrying out an additive process under computer control.
The 3D printing technology is used for both prototyping and distributed manufacturing with applications in architecture, construction (AEC), industrial design, automotive, aerospace, military, engineering, dental and medical industries, biotech (human tissue replacement), fashion, footwear, jewelry, eyewear, education, geographic information systems, food, and many other fields.
