63-533: A frequently cited criticism of the DoD is the expensive and often inefficient way that it buys and builds new things. The scope of this process can be seen in the Integrated Defense Acquisition, Technology, & Logistics Life Cycle Management Framework. One of the big challenges associated with these processes is the craftsmen-like nature of building these complex cyber-mechanical systems. A typical approach

126-417: A manufacturing process . Other terms that have been used as synonyms or hypernyms have included desktop manufacturing , rapid manufacturing (as the logical production-level successor to rapid prototyping ), and on-demand manufacturing (which echoes on-demand printing in the 2D sense of printing ). The fact that the application of the adjectives rapid and on-demand to the noun manufacturing

It can be done in a variety of processes in which material is deposited, joined or solidified under computer control , with the material being added together (such as plastics, liquids or powder grains being fused), typically layer by layer. In the 1980s, 3D printing techniques were considered suitable only for the production of functional or aesthetic prototypes, and

252-544: A 25% weight reduction, and reduced assembly times. A fuel nozzle is the perfect inroad for additive manufacturing in a jet engine since it allows for optimized design of the complex internals and it is a low-stress, non-rotating part. Similarly, in 2015, PW delivered their first AM parts in the PurePower PW1500G to Bombardier. Sticking to low-stress, non-rotating parts, PW selected the compressor stators and synch ring brackets to roll out this new manufacturing technology for

315-490: A 3D service provider specializing in Howtek single nozzle inkjet and SDI printer support. James K. McMahon worked with Steven Zoltan, 1972 drop-on-demand inkjet inventor, at Exxon and has a patent in 1978 that expanded the understanding of the single nozzle design inkjets (Alpha jets) and helped perfect the Howtek, Inc hot-melt inkjets.

META II was to begin in late 2010 and last 12 months. An infantry fighting vehicle library was to be compiled in late 2011 and continue for 1.5 years. Instant Foundry Adaptive through Bits (iFAB) attempted to design a manufacturing facility that could fabricate vehicles and could be reconfigured to manufacture other systems. The facility would be capable of manufacturing

504-405: A more appropriate term for it at the time was rapid prototyping . As of 2019 , 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; in this context, the term additive manufacturing can be used synonymously with 3D printing . One of the key advantages of 3D printing

567-510: A number of years. Both BPM 3D printers and SPI 3D printers use Howtek, Inc style Inkjets and Howtek, Inc style materials. Royden Sanders licensed the Helinksi patent prior to manufacturing the Modelmaker 6 Pro at Sanders prototype, Inc (SPI) in 1993. 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,

630-533: A proposal that won for system performance and manufacturability. 1,000 other competitors ultimately participated in the contest. The design then had to be validated for manufacturability feedback, foundry configuration, and instruction-generation tools, then tested and evaluated. DARPA was to award a $ 1 million prize for a hull design and $ 2 million in 2014 for the complete vehicle design. DARPA decided not to proceed with FANG 2 or 3 Challenges as originally planned. Open source challenges had received huge enthusiasm from

693-585: A record for shock absorption. In July 2024, researchers published a paper in Advanced Materials Technologies describing the development of artificial blood vessels using 3D-printing technology, which are as strong and durable as natural blood vessels . The process involved using a rotating spindle integrated into a 3D printer to create grafts from a water-based gel, which were then coated in biodegradable polyester molecules. Additive manufacturing or 3D printing has rapidly gained importance in

945-414: Is produced by additive manufacturing or 3D printing methods to enable quick prototyping and responses to tooling and fixture needs. Agile tooling uses a cost-effective and high-quality method to quickly respond to customer and market needs, and it can be used in hydro-forming , stamping , injection molding and other manufacturing processes. The general concept of and procedure to be used in 3D-printing

1008-466: Is the ability to produce very complex shapes or geometries that would be otherwise infeasible to construct by hand, including hollow parts or parts with internal truss structures to reduce weight while creating less material waste. Fused deposition modeling (FDM), which uses a continuous filament of a thermoplastic material, is the most common 3D printing process in use as of 2020 . The umbrella term additive manufacturing (AM) gained popularity in

1071-632: Is the technology's ability to produce complex geometries with high precision and accuracy. This is particularly relevant in the field of microwave engineering, where 3D printing can be used to produce components with unique properties that are difficult to achieve using traditional manufacturing methods. Additive Manufacturing processes generate minimal waste by adding material only where needed, unlike traditional methods that cut away excess material. This reduces both material costs and environmental impact. This reduction in waste also lowers energy consumption for material production and disposal, contributing to

1134-433: Is to break the system into subsystems and have separate teams embark on building the individual subsystems and optimize them for Size, Weight, and Power. Once the subsystems reach a reasonable level of development, an integration effort takes place to tie the subsystems together. The system is then tested against requirements which are almost never met on the first integration-testing cycle. The steps will then be iterated until

1197-580: The Amphibious Combat Vehicle program. The vehicle was to be capable of amphibious transport and have requirements similar to the U.S. Marine Corps Amphibious Combat Vehicle program. The vehicle design would be open source. In April 2013, DARPA awarded US$ 1 million to a three-man team of designers for its drivetrain for the Marine ACV. The team, Team Ground Systems, used the online design tools and open-source code provided by DARPA to put together

1260-543: The UV exposure area is controlled by a mask pattern or a scanning fiber transmitter. He filed a patent for this XYZ plotter, which was published on 10 November 1981. (JP S56-144478). His research results as journal papers were published in April and November 1981. However, there was no reaction to the series of his publications. His device was not highly evaluated in the laboratory and his boss did not show any interest. His research budget

1323-626: The stereolithography process. The application of the French inventors was abandoned by the French General Electric Company (now Alcatel-Alsthom) and CILAS (The Laser Consortium). The claimed reason was "for lack of business perspective". In 1983, Robert Howard started R.H. Research, later named Howtek, Inc. in Feb 1984 to develop a color inkjet 2D printer, Pixelmaster, commercialized in 1986, using Thermoplastic (hot-melt) plastic ink. A team

1386-448: The 1980s cost upwards of $ 300,000 ($ 650,000 in 2016 dollars). AM processes for metal sintering or melting (such as selective laser sintering , direct metal laser sintering , and selective laser melting) usually went by their own individual names in the 1980s and 1990s. At the time, all metalworking was done by processes that are now called non-additive ( casting , fabrication , stamping , and machining ); although plenty of automation

1449-515: The 2000s, inspired by the theme of material being added together ( in any of various ways ). In contrast, the term subtractive manufacturing appeared as a retronym for the large family of machining processes with material removal as their common process. The term 3D printing still referred only to the polymer technologies in most minds, and the term AM was more likely to be used in metalworking and end-use part production contexts than among polymer, inkjet, or stereolithography enthusiasts. By

1512-722: The 3D printing jewelry industry. 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. On 8 August 1984 a patent, US4575330, assigned to UVP, Inc., later assigned to Chuck Hull of 3D Systems Corporation was filed, his own patent for a stereolithography fabrication system, in which individual laminae or layers are added by curing photopolymers with impinging radiation, particle bombardment, chemical reaction or just ultraviolet light lasers . Hull defined

1575-541: The AVM program was to move to this model for building large, complex, heterogeneous cyber-mechanical systems for increased cost and schedule efficiencies. The goal of META was to analyse interactions between components and provide verification and validation (V&V) of designs without prototyping in order to shorten development time. META was to develop new languages or language extensions ( Generic Modeling Environment and CyPhyML ) that encapsulated sufficient complexity to compile

1638-528: The FANG challenge was built and tested successfully, and the meta design tools were transitioned to industry years earlier than planned. The vehicleforge.mil program attempted to provide the necessary infrastructure for sharing design files among distributed design teams. Similar approaches in software had proven very successful for collaboration and innovation, such as the "clone-and-own" paradigm commonly used on sites like github.com and sourceforge.net. Vehicleforge.mil

1701-413: The FANG vehicle. iFAB looked to lay the groundwork for development of a foundry-style manufacturing capability – taking as input a verified system design specified in an appropriate metalanguage – capable of rapid reconfiguration to accommodate a wide range of design variability and specifically targeted at the fabrication of military ground vehicles. Fast Adaptable Next-Generation Ground Vehicle (FANG GCV)

1764-445: The VIC 3D printer for this company is available with a video presentation showing a 3D model printed with a single nozzle inkjet. Another employee Herbert Menhennett formed a New Hampshire company HM Research in 1991 and introduced the Howtek, Inc, inkjet technology and thermoplastic materials to Royden Sanders of SDI and Bill Masters of Ballistic Particle Manufacturing (BPM) where he worked for

1827-456: The advantages of design for additive manufacturing , it is clear to engineers that much more is to come. One place that AM is making a significant inroad is in the aviation industry. With nearly 3.8 billion air travelers in 2016, the demand for fuel efficient and easily produced jet engines has never been higher. For large OEMs (original equipment manufacturers) like Pratt and Whitney (PW) and General Electric (GE) this means looking towards AM as

1890-449: The developing world. In 2012, Filabot developed a system for closing the loop with plastic and allows for any FDM or FFF 3D printer to be able to print with a wider range of plastics. In 2014, Benjamin S. Cook and Manos M. Tentzeris demonstrated the first multi-material, vertically integrated printed electronics additive manufacturing platform (VIPRE) which enabled 3D printing of functional electronics operating up to 40 GHz. As

1953-535: The early 2010s, the terms 3D printing and additive manufacturing evolved senses in which they were alternate umbrella terms for additive technologies, one being used in popular language by consumer-maker communities and the media, and the other used more formally by industrial end-use part producers, machine manufacturers, and global technical standards organizations. Until recently, the term 3D printing has been associated with machines low in price or capability. 3D printing and additive manufacturing reflect that

2016-597: The fabrication of articles on a substrate. On 2 July 1984, American entrepreneur Bill Masters filed a patent for his computer automated manufacturing process and system ( US 4665492 ). This filing is on record at the USPTO as the first 3D printing patent in history; it was the first of three patents belonging to Masters that laid the foundation for the 3D printing systems used today. On 16 July 1984, Alain Le Méhauté , Olivier de Witte, and Jean Claude André filed their patent for

2079-842: The field of engineering due to its many benefits. The vision of 3D printing is design freedom, individualization, decentralization and executing processes that were previously impossible through alternative methods. Some of these benefits include enabling faster prototyping, reducing manufacturing costs, increasing product customization, and improving product quality. Furthermore, the capabilities of 3D printing have extended beyond traditional manufacturing, like lightweight construction, or repair and maintenance with applications in prosthetics, bioprinting, food industry, rocket building, design and art and renewable energy systems. 3D printing technology can be used to produce battery energy storage systems, which are essential for sustainable energy generation and distribution. Another benefit of 3D printing

2142-449: The first commercial 3D printer, the SLA-1, later in 1987 or 1988. The technology used by most 3D printers to date—especially hobbyist and consumer-oriented models—is fused deposition modeling , a special application of plastic extrusion , developed in 1988 by S. Scott Crump and commercialized by his company Stratasys , which marketed its first FDM machine in 1992. Owning a 3D printer in

2205-426: The first decade in which metal end-use parts such as engine brackets and large nuts would be grown (either before or instead of machining) in job production rather than obligately being machined from bar stock or plate. 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

2268-449: The first patent describing 3D printing with rapid prototyping and controlled on-demand manufacturing of patterns. The patent states: As used herein the term printing is not intended in a limited sense but includes writing or other symbols, character or pattern formation with an ink. 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

2331-411: The first time. While AM is still playing a small role in the total number of parts in the jet engine manufacturing process, the return on investment can already be seen by the reduction in parts, the rapid production capabilities and the "optimized design in terms of performance and cost". As technology matured, several authors began to speculate that 3D printing could aid in sustainable development in

2394-414: The goal of many of them being to start developing commercial FDM 3D printers that were more accessible to the general public. As the various additive processes matured, it became clear that soon metal removal would no longer be the only metalworking process done through a tool or head moving through a 3D work envelope, transforming a mass of raw material into a desired shape layer by layer. The 2010s were

2457-427: The high cost would severely limit any widespread enjoyment of a process or apparatus satisfying the foregoing objects. It is therefore an additional object of the invention to minimize use to materials in a process of the indicated class. It is a further object of the invention that materials employed in such a process be salvaged for reuse. According to another aspect of the invention, a combination for writing and

2520-557: The like comprises a carrier for displaying an intelligence pattern and an arrangement for removing the pattern from the carrier. In 1974, David E. H. Jones laid out the concept of 3D printing in his regular column Ariadne in the journal New Scientist . Early additive manufacturing equipment and materials were developed in the 1980s. 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

2583-565: The manufacturing and research industries, as the technology was still relatively young and was too expensive for most consumers to be able to get their hands on. The 2000s was when larger scale use of the technology began being seen in industry, most often in the architecture and medical industries, though it was typically used for low accuracy modeling and testing, rather than the production of common manufactured goods or heavy prototyping. In 2005 users began to design and distribute plans for 3D printers that could print around 70% of their own parts,

2646-542: The mid-1990s, new techniques for material deposition were developed at Stanford and Carnegie Mellon University , including microcasting and sprayed materials. Sacrificial and support materials had also become more common, enabling new object geometries. 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 . The year 1993 also saw

2709-520: The original plans of which were designed by Adrian Bowyer at the University of Bath in 2004, with the name of the project being RepRap (Replicating Rapid-prototyper). Similarly, in 2006 the Fab@Home project was started by Evan Malone and Hod Lipson , another project whose purpose was to design a low-cost and open source fabrication system that users could develop on their own and post feedback on, making

2772-429: The price of printers started to drop people interested in this technology had more access and freedom to make what they wanted. As of 2014, the price for commercial printers was still high with the cost being over $ 2,000. The term "3D printing" originally referred to a process that deposits a binder material onto a powder bed with inkjet printer heads layer by layer. More recently, the popular vernacular has started using

2835-458: The process as a "system for generating three-dimensional objects by creating a cross-sectional pattern of the object to be formed". Hull's contribution was the STL (Stereolithography) file format and the digital slicing and infill strategies common to many processes today. In 1986, Charles "Chuck" Hull was granted a patent for this system, and his company, 3D Systems Corporation was formed and it released

2898-501: The project very collaborative. Much of the software for 3D printing available to the public at the time was open source , and as such was quickly distributed and improved upon by many individual users. In 2009 the Fused Deposition Modeling (FDM) printing process patents expired. This opened the door to a new wave of startup companies, many of which were established by major contributors of these open source initiatives, with

2961-523: The public, but military designs require specific engineering qualifications and the use of sensitive materials that must be kept out of the public domain. In February 2014, DARPA began transitioning AVM into the defense and commercial industry through the Digital Manufacturing and Design Innovation Institute (DMDII) effort, which is to be a national resource to accelerate innovation in digital manufacturing. The drivetrain and power pack developed under

3024-462: The start of an inkjet 3D printer company initially named Sanders Prototype, Inc and later named Solidscape , introducing a high-precision polymer jet fabrication system with soluble support structures, (categorized as a "dot-on-dot" technique). In 1995 the Fraunhofer Society developed the selective laser melting process. In the early 2000s 3D printers were still largely being used just in

3087-549: The surface for forming symbols, characters, or patterns of intelligence by marking. The preferred ink is of a hot melt type. The range of commercially available ink compositions which could meet the requirements of the invention are not known at the present time. However, satisfactory printing according to the invention has been achieved with the conductive metal alloy as ink. But in terms of material requirements for such large and continuous displays, if consumed at theretofore known rates, but increased in proportion to increase in size,

3150-443: The system meets its requirements. This is a costly approach, especially compared with something like chip production. Intel, for instance, has an excellent track record in getting systems right in the design phase so that extensive testing and integration are not needed. This "correct-by-construction" methodology is powerful and would not be possible without high-level design languages to support validation and verification. The goal of

3213-447: The technologies share the theme of material addition or joining throughout a 3D work envelope under automated control. Peter Zelinski, the editor-in-chief of Additive Manufacturing magazine, pointed out in 2017 that the terms are still often synonymous in casual usage, but some manufacturing industry experts are trying to make a distinction whereby additive manufacturing comprises 3D printing plus other technologies or other aspects of

3276-431: The term to encompass a wider variety of additive-manufacturing techniques such as electron-beam additive manufacturing and selective laser melting. The United States and global technical standards use the official term additive manufacturing for this broader sense. The most commonly used 3D printing process (46% as of 2018 ) is a material extrusion technique called fused deposition modeling , or FDM. While FDM technology

3339-555: The winning design. The Chassis/Integrated Survivability Challenge was to last three months and begin in the middle of 2013 subsequent to the Mobility/Drivetrain Challenge. A prize of $ .5–1 million for the winning design(s) was to be awarded. The third challenge, the Total Platform Challenge was to last six months and begin in early 2014. A prototype would be completed that would be eligible for consideration for

3402-504: Was a portfolio of three loosely related projects. The FANG GCV attempted to crowdsource the design of an infantry fighting vehicle culminating in prototypes. Participants were to use the META metalanguage with the option to use Vehicleforge. The program was to occur in three phases. The Mobility/Drivetrain Challenge lasted three months and began in 2013. A prize of $ 0.5–1 million was awarded for

3465-650: Was also described by Raymond F. Jones in his story, "Tools of the Trade", published in the November 1950 issue of Astounding Science Fiction magazine. He referred to it as a "molecular spray" in that story. In 1971, Johannes F Gottwald patented the Liquid Metal Recorder, U.S. patent 3596285A, a continuous inkjet metal material device to form a removable metal fabrication on a reusable surface for immediate use or salvaged for printing again by remelting. This appears to be

3528-509: Was applied to those technologies (such as by robot welding and CNC ), the idea of a tool or head moving through a 3D work envelope transforming a mass of raw material into a desired shape with a toolpath was associated in metalworking only with processes that removed metal (rather than adding it), such as CNC milling , CNC EDM , and many others. However, the automated techniques that added metal, which would later be called additive manufacturing, were beginning to challenge that assumption. By

3591-425: Was first described by Murray Leinster in his 1945 short story "Things Pass By": "But this constructor is both efficient and flexible. I feed magnetronic plastics — the stuff they make houses and ships of nowadays — into this moving arm. It makes drawings in the air following drawings it scans with photo-cells. But plastic comes out of the end of the drawing arm and hardens as it comes ... following drawings only" It

3654-565: Was invented after the other two most popular technologies, stereolithography (SLA) and selective laser sintering (SLS), FDM is typically the most inexpensive of the three by a large margin, which lends to the popularity of the process. As of 2020, 3D printers have reached the level of quality and price that allows most people to enter the world of 3D printing. In 2020 decent quality printers can be found for less than US$ 200 for entry-level machines. These more affordable printers are usually fused deposition modeling (FDM) printers. In November 2021

3717-464: Was just 60,000 yen or $ 545 a year. Acquiring the patent rights for the XYZ plotter was abandoned, and the project was terminated. A US 4323756 patent, method of fabricating articles by sequential deposition , granted on 6 April 1982 to Raytheon Technologies Corp describes using hundreds or thousands of "layers" of powdered metal and a laser energy source and represents an early reference to forming "layers" and

3780-428: Was novel in the 2000s reveals the long-prevailing mental model of the previous industrial era during which almost all production manufacturing had involved long lead times for laborious tooling development. Today, the term subtractive has not replaced the term machining , instead complementing it when a term that covers any removal method is needed. Agile tooling is the use of modular means to design tooling that
