  • Spotlight: Additive Manufacturing: Building the Future
    Updated July 2019 Spotlight: Solving Industry’s Additive Manufacturing Challenges | 2 Critical Need for Additive Manufacturing Additive manufacturing (AM), often called 3D printing,1 uses a computer-aided design (CAD) file to precisely control layer-by- layer, or point-by-point, buildup of material into three- dimensional objects. The technology can vastly improve manufacturing processes by eliminating the design constraints and material waste of traditional processes like casting or machining. Ultimately, AM could produce parts energy efficiently that meet or exceed the functional requirements of existing products yet weigh far less. Today’s AM technologies already benefit critical economic sectors, from buildings to aerospace and defense (A&D). Applications include rapid prototyping, tailored medical prosthetics, on-site part repairs, mold casting, and other consumer and industrial products. Wider use of AM components is restricted, in part, by the inability to validate and verify AM part quality and structural integrity, particularly in tightly regulated industries like A&D, biomedicine, and transportation. In addition, materials costs can be high, and improvements are needed in process controls, surface finishes, and throughput to enable broader adoption of AM techniques and products. Despite these challenges, the potential economy-wide savings from broader adoption of AM systems are significant. The U.S. Department of Energy (DOE) estimates that (compared to traditional manufacturing) AM AM Adoption is Rapidly Growing for 3D Printing Applications might slash waste and materials costs by nearly 90% and cut Diverse Applications 2 manufacturing energy use in half.

  • Supplementary Appendix: the History of the 3D Printing Industry The
    Supplementary Appendix: The History of the 3D Printing Industry The advent of 3D printing can be traced back to a Frenchmen in Paris in 1859 named François Willème who created photo sculptures of real people using similar techniques of that to the techniques used by 3D printing in today’s world (Norman, 2016: Walters and Thirkell, 2007). In 1892 J.E. Blanther, a manufacturer of contour relief maps, proposed a layering method to make a mold for topographical relief maps. The method involved impressing topographical contour lines on a number of wax plates that were stacked, cut and smoothed to form a three-dimensional surface that created a raised relief map. In 1972, Matsubara of Mitsubishi Motors suggested a topographical process that used photo-hardening materials to produce layered parts (Bourell et al, 2009). Until the late 1970s the alternative primary manufacturing idea - adding material – had received comparatively little attention (except in the electronics industry for chip manufacture, where it was, and still is, ubiquitous, if microscopic). According to Bradshaw et al (2010) the advent of 3D printing started with a joke written in 1974 and a patent granted in 1977. David Jones a writer by the pen name ‘Daedalus’ described 3D printing as joke in the New Scientist. He gave a descriptive yet imaginative technique that proposed creation of solid objects. Coincidently, in 1977 Wyn Kelly Swainson was granted a patent for the similar idea. However, the patent was filed way before Jones piece was published. It wasn’t until 1981 that Hideo Kodama of Nagoya Municipal Industrial Research Institute published the first account of a functional photopolymer rapid prototyping system (Kodama, 1981: Bourell et al, 2009: AV plastics).

  • 1. Introduction 2. History
    1. Introduction 3D printing is a form of additive manufacturing technology where a three dimensional object is created by laying down successive layers of material. It is also known as Additive manufacturing. A method of Additive Manufacturing that adds material to an object layer by layer to create the final product. It can “print” in plastic, metal, nylon, and over a hundred other materials. A 3D printer is a type of industrial robot. There are many uses of 3D Printing e.g. architecture, construction, industrial design, engineering, dental and medical industries, biotech (human tissue replacement), fashion, 3D Printer footwear, jewelry, education, geographic information systems, food, and many other fields. The cost of 3D printers has decreased dramatically since about 2010, with machines that used to cost $20,000 now costing less than $1,000. For instance, as of 2013, several companies and individuals are selling parts, with prices starting at about €400/US$500. 2. History The technology for printing physical 3D objects from digital data was first developed by Charles Hull in 1984. He named the technique as Stereo lithography and obtained a patent for the technique in 1986. In Stereo lithography layers are added by curing photopolymers with UV lasers. He also developed the STL (Stereolithography) widely accepted by 3D printing software. Charles Hull STL is a file format native to the CAD (Computer Aided Design) software created by 3D Systems. Stereolithography is a "system for generating three- dimensional objects by creating a cross-sectional pattern of the object to be formed. STL is also known as Standard Tessellation Language.

    micromachines Review Application of Stereolithography Based 3D Printing Technology in Investment Casting Muslim Mukhtarkhanov, Asma Perveen and Didier Talamona * School of Engineering and Digital Sciences, Department of Mechanical and Aerospace Engineering, Nazarbayev University, Nursultan 010000, Kazakhstan; [email protected] (M.M.); [email protected] (A.P.) * Correspondence: [email protected]; Tel.: +7-(7172)-70-65-96 Received: 5 September 2020; Accepted: 13 October 2020; Published: 19 October 2020 Abstract: Advanced methods for manufacturing high quality parts should be used to ensure the production of competitive products for the world market. Investment casting (IC) is a process where a wax pattern is used as a sacrificial pattern to manufacture high precision casting of solid metal parts. Rapid casting is in turn, a technique that eases the IC process by combining additive manufacturing (AM) technologies with IC. The use of AM technologies to create patterns for new industrial products is a unique opportunity to develop cost-effective methods for producing investment casting parts in a timely manner. Particularly, stereolithography (SLA) based AM is of interest due to its high dimensional accuracy and the smooth surface quality of the printed parts. From the first appearance of commercially available SLA printers in the market, it took a few decades until desktop SLA printers became available to consumers at a reasonable price. Therefore, the aim of this review paper is to analyze the state-of-the-art and applicability of SLA based 3D printing technology in IC manufacturing, as SLA based AM technologies have been gaining enormous popularity in recent times.

  • History of 3D Printing: the Free Beginner's Guide
    3D Printing for the Bioscience Classroom History of 3D Printing: The Free Beginner’s Guide The earliest 3D printing technologies first became visible in the late 1980’s, at which time they were called Rapid Prototyping (RP) technologies. This is because the processes were originally conceived as a fast and more cost-effective method for creating prototypes for product development within industry. As an interesting aside, the very first patent application for RP technology was filed by a Dr Kodama, in Japan, in May 1980. Unfortunately for Dr Kodama, the full patent specification was subsequently not filed before the one year deadline after the application, which is particularly disastrous considering that he was a patent lawyer! In real terms, however, the origins of 3D printing can be traced back to 1986, when the first patent was issued for stereolithography apparatus (SLA). This patent belonged to one Charles (Chuck) Hull, who first invented his SLA machine in 1983. Hull went on to co-found 3D Systems Corporation — one of the largest and most prolific organizations operating in the 3D printing sector today. 3D Systems’ first commercial RP system, the SLA-1, was introduced in 1987 and following rigorous testing the first of these system was sold in 1988. As is fairly typical with new technology, while SLA can claim to be the first past the starting post, it was not the only RP technology in development at this time, for, in 1987, Carl Deckard, who was working at the University of Texas, filed a patent in the US for the Selective Laser Sintering (SLS) RP process.

For example, supply chains and product storage could essentially be eliminated if product design became entirely digital. Although 3D printing is potentially highly beneficial for the environment, awareness of 3D printing’s impact on the environment is essential for healthy development and should be addressed before the technology is used on an industrial scale.

Additive manufacturing is the most recent and the most revolutionary technology in the production industry. It is an unconventional method of manufacturing. In this manufacturing method, material is added one layer upon another layer to get the required shape and size of object. Most complex objects can be built very easily by this technology. Additive manufacturing has the capability to reduce the supply chain by reducing a number of processing stages of a product. Additive manufacturing technology developed a lot from the day 3D printing technique, introduced as Stereolithography in 1984 by Charles W. Hull. Today we have different types of 3D printing techniques such as polymer resin based printing, wire based printing(FDM) and powder based printing(SLS) and some hybrid Additive manufacturing like High speed sintering. Additive manufacturing has applications spread from Aerospace industry to Toy industry and from Biomedical industry to Construction field.

Since its beginning it was thought of as an open source project, in other words the engineering of the printer itself was meant to be open to peer review rather than patented and worked on by a small group of scientists.1 In a very short time, thanks to its open source platform the project gained momentum and today the desktop 3d printer has gone from open hardware projects like Ultimaker2 to closed source desktop 3d printers like Makerbot3 as well as service based companies which will print almost any shape and function out of plastic or even metal.4 Early on the RepRap team theorized that a cheap, affordable 3d printer would enable people to produce part of their household items on their own.
