3D printing has existed for decades within certain manufacturing industries where many legal regimes, including patents, industrial design rights, copyrights, and trademarks may apply. DMLS or Direct Metal Laser Sintering is the most popular method of 3D printing in metal. Inside the dead zone, oxygen prohibits light from curing the resin situated closest to the window therefore allowing the continuous flow of liquid beneath the printed part. , There are many different branded Additive manufacturing processes, that can be grouped into seven categories:, The main differences between processes are in the way layers are deposited to create parts and in the materials that are used. The heart of the CLIP process is Digital Light Synthesis technology. It stores information using curved triangulations.. Spence writes that "the world we are entering is one in which the most powerful global flows will be ideas and digital capital, not goods, services, and traditional capital. " After Defense Distributed released their plans, questions were raised regarding the effects that 3D printing and widespread consumer-level CNC machining may have on gun control effectiveness. Using CAD Software for 3D Printing CAD software are highly technical tools that are used in industrial design, architecture, aerospace engineering, mechanical design, and other fronts.  3D printing advocates have suggested that such regulations would be futile, could cripple the 3D printing industry, and could infringe on free speech rights, with early pioneer of 3D printing Professor Hod Lipson suggesting that gunpowder could be controlled instead. During the process, stainless steel reaches a temperature of almost 3000 °F.  The process was originally created by Adrian Bowyer and was then built upon by German RepRap.. ", "According to another aspect of the invention, a combination for writing and the like comprises a carrier for displaying an intelligence pattern and an arrangement for removing the pattern from the carrier.  Current circuit board manufacturing can be a tedious process depending on the design.  The earliest application of additive manufacturing was on the toolroom end of the manufacturing spectrum. It is still the case that casting, fabrication, stamping, and machining are more prevalent than additive manufacturing in metalworking, but AM is now beginning to make significant inroads, and with the advantages of design for additive manufacturing, it is clear to engineers that much more is to come. Automotive enthusiasts all over the world are using 3D printed parts to restore old cars. With 3D printing, making the master model has become easier than ever before. Image source: lboro.ac.uk, Material Jetting schematics. , 3D printing has entered the world of clothing, with fashion designers experimenting with 3D-printed bikinis, shoes, and dresses. However, strictly speaking when people ask: “What is 3D printing?” it can be defined as “the fabrication of objects through the deposition of a material using a … In an additive process an object is created by laying down successive layers of material until the object is created. Another technique fuses parts of the layer and then moves upward in the working area, adding another layer of granules and repeating the process until the piece has built up. Hull defined the process as a "system for generating three-dimensional objects by creating a cross-sectional pattern of the object to be formed,". "Once this is achieved, the marginal cost of the hardware is relatively low (and declines as scale rises), and the marginal cost of replicating the software is essentially zero. Multi Jet Fusion technology was developed by Hewlett Packard and works with a sweeping arm which deposits a layer of powder and then another arm equipped with inkjets which selectively applies a binder agent over the material. , Additional hazards include burns from hot surfaces such as lamps and print head blocks, exposure to laser or ultraviolet radiation, electrical shock, mechanical injury from being struck by moving parts, and noise and ergonomic hazards.  Each photopolymer layer is cured with UV light after it is jetted, producing fully cured models that can be handled and used immediately, without post-curing. 3D reconstruction often includes errors.. Wax and thermoplastic hot-melts were jetted next by DOD. The main considerations in choosing a machine are generally speed, costs of the 3D printer, of the printed prototype, choice and cost of the materials, and color capabilities.  A National Institute for Occupational Safety and Health (NIOSH) study noted particle emissions from a fused filament peaked a few minutes after printing started and returned to baseline levels 100 minutes after printing ended. To become a viable industrial production option, there are a couple of challenges that 4D printing must overcome. In April 1980, Hideo Kodama of Nagoya Municipal Industrial Research Institute invented two additive methods for fabricating three-dimensional plastic models with photo-hardening thermoset polymer, where the UV exposure area is controlled by a mask pattern or a scanning fiber transmitter. The Delta-TT Cup designed by Dr. Guido Grappiolo and LimaCorporate is made of Trabecular Titanium, which is characterized by a regular, three-dimensional, hexagonal cell structure that imitates trabecular bone morphology. Spence believes that labor, no matter how inexpensive, will become a less important asset for growth and employment expansion, with labor-intensive, process-oriented manufacturing becoming less effective, and that re-localization will appear in both developed and developing countries. 3D printing is like having a small-scale manufacturing device right in your home or office. Momeni, Farhang, Xun Liu, and Jun Ni.  Yet another approach uses a synthetic resin that is solidified using LEDs. Image source: Wikipedia, made by user Zureks. , The term 3D printing originally referred to a powder bed process employing standard and custom inkjet print heads, developed at MIT by Emanuel Sachs in 1993 and commercialized by Soligen Technologies, Extrude Hone Corporation, and Z Corporation. , As of March 2018,[update] the US Government has set 3D printer emission standards for only a limited number of compounds. The inkjets also deposit a detailing agent around the binder to ensure precise dimensionality and smooth surfaces. Nowadays there are numerous examples of end-use 3D printed consumer products. Car manufacturers have been utilizing 3D printing for a long time. Therefore, if a type of wheel is patented, printing, using, or selling such a wheel could be an infringement of the patent..  As of 2012[update], 3D bio-printing technology has been studied by biotechnology firms and academia for possible use in tissue engineering applications in which organs and body parts are built using inkjet printing techniques. ", In 1974, David E. H. Jones laid out the concept of 3D printing in his regular column Ariadne in the journal New Scientist. James K. McMahon who was hired by Howtek, Inc to help develop the inkjet, later worked at Sanders Prototype and now operates Layer Grown Model Technology, a 3D service provider specializing in Howtek single nozzle inkjet and SDI printer support. Printed prototypes are also very common in the arts, animation and fashion studies as well. Some printing techniques require internal supports to be built for overhanging features during construction. This appears to be the first patent describing 3D printing with rapid prototyping and controlled on-demand manufacturing of patterns. One example of AM integration with aerospace was in 2016 when Airbus was delivered the first of GE’s LEAP engine. However, there is not much jurisprudence to say how these laws will apply if 3D printers become mainstream and individuals or hobbyist communities begin manufacturing items for personal use, for non-profit distribution, or for sale. Why use 3D Printers for Rapid Prototyping? The nozzle is heated to melt the material and can be moved in both horizontal and vertical directions by a numerically controlled mechanism. As late as the 1970s the term recorder was associated with inkjet. , Internationally, where gun controls are generally stricter than in the United States, some commentators have said the impact may be more strongly felt since alternative firearms are not as easily obtainable. ", Spence believes that, unlike prior digital technologies, which drove firms to deploy underutilized pools of valuable labor around the world, the motivating force in the current wave of digital technologies "is cost reduction via the replacement of labor." , Hazards to health and safety also exist from post-processing activities done to finish parts after they have been printed.  For that printer resolution, specifying a mesh resolution of 0.01–0.03 mm and a chord length ≤ 0.016 mm generate an optimal STL output file for a given model input file. (by courtesy of Springer-VDI-Verlag, Düsseldorf) (https://www.dguv.de/medien/ifa/de/pub/grl/pdf/2018_148.pdf), Health and safety hazards of nanomaterials, European Agency for Safety and Health at Work, National Institute for Occupational Safety and Health, Institute for Occupational Safety and Health, List of notable 3D printed weapons and parts, "Learning Course: Additive Manufacturing – Additive Fertigung", "Most used 3D printing technologies 2017–2018 | Statistic", "ISO/ASTM 52900:2015 – Additive manufacturing – General principles – Terminology", "Additive manufacturing and 3D printing are two different things", "Disdpositif pour realiser un modele de piece industrielle", "Alain Le Méhauté, The Man Who Submitted Patent For SLA 3D Printing Before Chuck Hull", "Interview d'Alain Le Méhauté, l'un des pères de l'impression (Interview of Alain Le Mehaute, one of the 3D printinf technologies fathers) 3D", Apparatus for Production of Three-Dimensional Objects by Stereolithography (8 August 1984), "History of 3D Printing: When Was 3D Printing Invented?  Some US legislators have proposed regulations on 3D printers to prevent them from being used for printing guns. Both BPM 3D printers and SPI 3D printers use Howtek, Inc style Inkjets and Howtek, Inc style materials.  The toxicity from emissions varies by source material due to differences in size, chemical properties, and quantity of emitted particles. This revolution is spreading to the production of goods, where robots and 3D printing are displacing labor." DLP utilizes other light sources like arc lamps. Due to the individualized nature of healthcare, 3D printing is a perfect solution for this industry. The cores are then prepared for lamination. | Bureau of Alcohol, Tobacco, Firearms and Explosives", "State Dept Censors 3D Gun Plans, Citing 'National Security, "Wishful Thinking Is Control Freaks' Last Defense Against 3D-Printed Guns", "The Pirate Bay steps in to distribute 3-D gun designs", "US demands removal of 3D printed gun blueprints", "España y EE.UU.  As of 2019[update], the precision, repeatability, and material range of 3D printing have increased to the point that some 3D printing processes are considered viable as an industrial-production technology, whereby the term additive manufacturing can be used synonymously with 3D printing.  Sanders (SDI) first Modelmaker 6Pro customer was Hitchner Corporations, Metal Casting Technology, Inc in Milford, NH a mile from the SDI facility in late 1993-1995 casting golf clubs and auto engine parts. The LEAP engine is the best selling engine in the aerospace industry due to its high level of efficiency and GE saves $3 million per aircraft by 3D printing the fuel nozzles, so this single 3D printed part generates hundreds of millions of dollars of financial benefit. , Other methods cure liquid materials using different sophisticated technologies, such as stereolithography. Finally, the layer is exposed to a burst of thermal energy that causes the agents to react. The creation of a 3D printed object is achieved using additive processes. "3D printing technology in education environment." 3D printing services allow you to bring to reality the 3D designs that you have in mind. To be allowed to do these things, where an active intellectual property was involved, a person would have to contact the owner and ask for a licence, which may come with conditions and a price. Off the shelf machines were increasingly capable of producing practical household applications, for example, ornamental objects. Feeding the file to your printer can be done via USB, SD or Wi-Fi. Over the last decade, more than 100,000 hip replacements have been 3D printed by GE Additive. The 3D printing apparatus is usually attached to a multi-axis robotic arm and consists of a nozzle that deposits metal powder or wire on a surface and an energy source (laser, electron beam or plasma arc) that melts it, forming a solid object. The term ink as used in is intended to include not only dye or pigment-containing materials, but any flowable substance or composition suited for application to the surface for forming symbols, characters, or patterns of intelligence by marking". With RSM, a technician uses silicone to take an impression of the ear canal, that impression is 3D scanned, and after some minor tweaking the model is 3D printed with a resin 3D printer. , Vanessa Friedman, fashion director and chief fashion critic at The New York Times, says 3D printing will have a significant value for fashion companies down the road, especially if it transforms into a print-it-yourself tool for shoppers. Construction of a model with contemporary methods can take anywhere from several hours to several days, depending on the method used and the size and complexity of the model. DLP is relatively quick compared to other 3D printing technologies. ", Research on the health and safety concerns of 3D printing is new and in development due to the recent proliferation of 3D printing devices. The versatility of this technology and materials can lead to advances in multiple fields of industry, including space, commercial and the medical field.  RepRap is a wiki based website that was created to hold all information on 3d printing, and has developed into a community that aims to bring 3D printing to everyone. Acquiring the patent rights for the XYZ plotter was abandoned, and the project was terminated. As opposed to utilizing a solid block of material and removing all the unnecessary material until the desired object is created, 3D printing creates objects by bonding the print material one layer at a time. , In 2018, 3D printing technology was used for the first time to create a matrix for cell immobilization in fermentation. , Hazard controls include using manufacturer-supplied covers and full enclosures, using proper ventilation, keeping workers away from the printer, using respirators, turning off the printer if it jammed, and using lower emission printers and filaments.  Hull's contribution was the STL (Stereolithography) file format and the digital slicing and infill strategies common to many processes today. No chromium(VI) compounds were detected in the workplace air during the process when materials containing chromium were processed, and the assessment criteria were complied with during processes with the other metal powders. Layers of living cells are deposited onto a gel medium and slowly built up to form three dimensional structures.  The FAA has jurisdiction over such fabrication because all aircraft parts must be made under FAA production approval or under other FAA regulatory categories. Others have suggested that as more and more 3D printers start to enter people's homes, the conventional relationship between the home and the workplace might get further eroded. Traditional glass lenses don’t start out thin and light; they’re cut from a much larger block of material called a blank, about 80% of which goes to waste. Metallographic materials of 3D printing is also being researched. 3D printing, also known as additive manufacturing, is a manufacturing process where a 3D printer creates three-dimensional objects by depositing materials layer by layer in accordance to the … Charles Hull invented the first commercial 3D printer and offered it for sale through his company 3D Systems in 1986. The following example marks a significant 3D printing manufacturing milestone: GE Aviation has 3D printed 30,000 Cobalt-chrome fuel nozzles for its LEAP aircraft engines. ", Grujović, N., Radović, M., Kanjevac, V., Borota, J., Grujović, G., & Divac, D. (September 2011). for those who perform routine tasks. On-demand customization of glasses is possible with rapid prototyping. Using 3D printers for these purposes is called rapid prototyping. On this new liquid surface, the subsequent layer pattern is traced, joining the previous layer.  Based on animal studies, carbon nanotubes and carbon nanofibers sometimes used in fused filament printing can cause pulmonary effects including inflammation, granulomas, and pulmonary fibrosis when at the nanoparticle size. 3D printing enables you to produce complex shapes using less material than traditional manufacturing methods. . SLA was invented in 1986 by Charles Hull, who also at the time founded the company, 3D Systems. 3D printing in a one-step process where you do not need to connect different parts together has resulted in the huge popularity of 3D printing.  Many of these systems are used for rapid prototyping, before mass production methods are employed. Typically, a CAD model contains data such as tolerance, dimensions, material properties, specific information about the manufacturing process. The idea of investment casting with Solid-Ink jetted images or patterns in 1984 led to the first patent to form articles from particle deposition in 1989, issued in 1992. Image source: Merlin project. One such example is when Australian engineers printed parts to bring a Delage Type-C back to life.
