Here are suggested tips. @David09 - A DDC control system is not just limited to air conditioners or heaters however. This metal AM machine is able to churn out serial production series efficiently and reliably; one of the company’s first DM P2500 printers has been running 24/7 since 2013, according to Digital Metal. For instance, a safety instrumented system might monitor the wellhead pressure of an oil well and take action if the pressure of that well exceeds what is considered safe. By contrast, a DDM designer would create a digital 3D model of the cup, then turn production over to the computer, which would digitally slice it into a stack of wafer-thin layers, print them out, and fuse them together. Many safety systems can also benefit from the technologies offered by direct digital control. Two decades hence, the defense industry may look vastly different, thanks to shrinking Pentagon budgets, industrial consolidation and continuing globalization. Contributors Include Industrial Designers and Mechanical Engineers on the FATHOM Engineering & Design Team While additive manufacturing (AM) has mostly been used as a prototyping tool, in the If you continue browsing the site, you agree to the use of cookies on this website. Introduction. Many military systems have been in service for decades — B-52s, A-10s, surface ships — yet spare parts often become hard to obtain. It is becoming price-competitive with traditional manufacturing techniques, especially ones for typical defense quantities. Most notably, digital textile printing is referred to when identifying either printing smaller designs onto garments (T-shirts, dresses, promotional wear; abbreviated as DTG, which stands for Direct to garment printing) and printing larger designs onto large format rolls of textile. If a university team can already design and build a small aircraft for fun, so can someone with more nefarious purposes in mind. @allenJo - I think that’s a fair point. The very large range of available 3D Printing technologies and materials often means that several of them may be viable, but each offers variations in dimensional accuracy, surface finish and post-processing requirements.. DDM can be used to produce these parts, which also turns our present thinking about niche firms and preserving existing markets on its head. Cyber Physical System (CPS) innovations that could find direct application in vertical sectors are currently accounting for more than $32.3 trillion in economic The entire structure including wings, integral control surfaces and access hatches was printed out. Other methods of printing include fused deposition modeling, which lays down liquefied plastic or metal through a thin filament that forms into the desired shape as it hardens; stereo-lithography, which uses ultraviolet lasers to cure photopolymer “resin” one layer at a time; and selective laser sintering, which uses a high-powered laser to selectively fuse powders of plastic, ceramic, glass and even metals such as titanium and aluminum into the desired 3D shape. In the 1950s, the Air Force and Army fostered the industry’s adoption of numerically controlled machine tools, lending these automated systems to contractors as part of a government-furnished equipment program. An automotive original equipment manufacturer (OEM) can design the entire manufacturing process digitally (tooling, machining, assembly sequencing, and factory layout) at the same time that designers are designing the next vehicle program. But the impact will not just be at the spare part or subcontractor level. Additive Manufacturing I Additive Manufacturing (AM) refers to a process by which digital 3D design data is used to build up a component in layers by depositing material. #1 MYTH You must have a Digital … With microprocessors as efficient as they are, I think they can act quickly to restore the target temperature. This future is bright for defense DDM, but not yet rosy. After it does kick in, how long does it take to bring the temperature back down to 75? Process & Material Selection : Biomaterials, Metal Technology & Processes, Multiple Materials, Hybrids, Ceramics and Bioceramics, Composite Materials and future directions 7. Digital manufacturing is utilized across industries. DDM’s impact thus might be felt in the area of components and parts, and interestingly enough, not just for new systems. For instance, a direct digital control system meant to monitor and maintain a certain temperature and air pressure within a building can monitor various factors. Direct Digital Manufacturing, Distributed Manufacturing and Mass Customization 8. Data Communication & Networking in. Chapter 2 Digital Manufacturing Today’s Business Requirements Drive Change & … What is Direct Digital Manufacturing (DDM)? What is Direct Digital Manufacturing (DDM)? I don’t know all the technical specs but I am sure that in the event of a fire, the unit sends a message to the central monitoring facility, based on temperature sensors. The computer kicks in with the AC to bring the temperature back down to 75. The Digital Metal DM P2500 is a certified metal 3D printer (CE and UL) that is compatible with certified metal materials (ISO 22068). As its name implies, additive manufacturing adds material to create an object. The technology can answer many needs, but unless the defense industry proves its interest in actually being innovative and the Defense Department proves its willingness to enable industry to take risks, DDM will simply be yet another technology whose research was initially paid for by the military, but where the military and defense industry end up behind the civilian sector in actual use and benefit — as happened in information technology. Instead of the old method of metallic braces and corrective retainers clumsily created out of putty, dental supply companies like Invisalign now use the stereolithography version of DDM to produce aligner trays for straightening teeth. Whatever lag times may exist will be minimal in my opinion. Presently, DDM is not an option, not just because of capability but due to issues of process, safety and certification. Fortunately we’ve never had to use this part of the service but it’s good to know that it’s there. As computers and processing technology improves, the possibilities for many of these systems may also improve. Other DoD-supported research projects are poised to take DDM to the next technical level, such as efforts to develop ever-more sophisticated lasers and manufacturing systems, further work on industrial- and military-strength products, and efforts to make DDM work at an even more scalable level, including through the use of nanotechnology. in Computer Integrated Manufacture Senior PLM Consultant, IBM Indonesia (Retired) Senior Manager, Product Development Multistrada Arah Sarana Data Communication & Networking in Manufacturing System. When evaluating Direct Digital Manufacturing for production, take a methodical analysis of cost, design, assembly, materials, and process to fully understand its benefits. Manufacturing System. manufacturing is related to ICT intensive services and out of every dollar invested in manufacturing infrastructure 19 cents go to ICT services. But what happens if the temperature begins to rise again? The Biden administration should relax, not expand, centralized regulatory reviews, The consequences of a fragmenting, less global internet, Four steps to undo the harms of legacy infrastructure in the COVID-19 recovery. Direct Digital Manufacturing (DDM) is a process that produces parts directly from a CAD file. Digital textile printing is described as any ink jet based method of printing colorants onto fabric. To accomplish whatever task the system has been created to maintain, it might rely on collecting and processing data before changing conditions or attempting to meet certain specifications. Unlike traditional machining methods, which involve working from a rough mold and then cutting away to achieve the desired complex shape, direct digital manufacturing creates the shape precisely and instantly, using additive fabrication. Still, a DDM future will happen only if we begin to work through the processes and procedures today. And for good reason: The Digital Factory promises to completely revolutionize not only manufacturing processes as we know them, but manufacturers themselves. Designing for Additive Manufacturing 6. This is not just a concern when it comes to other states, but DDM may even become a game changer for adversaries ranging down to the insurgent level, who stand ready to gain design and manufacturing capabilities once limited to nation-state arsenals. The use of DDM will only grow in the years ahead and may well alter forever defense design, manufacturing and acquisitions. What incentive exists for a company that wants to explore that risk for the reward? Moreover, it lowers the barriers of entry to innovative firms outside the defense space. Yet the lower energy demands and material waste mean lower manufacturing costs, thus producing savings that could get passed on to the Defense Department. That said, the digital transformation of pharma and biotech industries has already started, as many companies are developing roadmaps for digital transformation, and many have already started to adopt these newer digital technologies.
