  • Additive Manufacturing: The Future of Customization, Efficiency, and Sustainability

    Additive Manufacturing: The Future of Customization, Efficiency, and Sustainability

    Additive manufacturing, also known as 3D printing, has been rapidly gaining popularity in recent years. With its ability to create highly customized products quickly and efficiently, it has been hailed as the future of manufacturing. Here are five reasons why additive manufacturing is set to revolutionize the industry:

    Customization

    Additive manufacturing offers unparalleled customization options compared to traditional manufacturing methods. With the use of 3D modeling software, designers can create complex and intricate designs, with the printer capable of producing these designs in a matter of hours. However, with customization comes the risk of over-engineering or overspending on features that the customer may not want or need. To mitigate this risk, manufacturers can use data-driven insights to guide their design decisions, seeking feedback from customers at every stage of the product development process.

    Reduced Waste

    Additive manufacturing is known for producing significantly less waste than traditional manufacturing methods. As the printer only produces the exact amount of material needed to create the product, there is no excess material to dispose of. However, the use of plastic-based materials in 3D printing can also result in environmental risks. To mitigate this risk, manufacturers can use alternative materials, such as biodegradable or recycled materials, to reduce their carbon footprint.

    Faster Prototyping

    Additive manufacturing enables companies to prototype and iterate designs faster than traditional manufacturing methods. With 3D printing, manufacturers can produce and test multiple design iterations in a matter of days, allowing for more agile product development. However, there is a risk of over-prototyping or spending too much time on design iterations, delaying the product development process. To mitigate this risk, manufacturers should establish clear goals and timelines for each stage of the product development process.

    Sustainability

    Additive manufacturing offers significant sustainability benefits compared to traditional manufacturing methods. By producing parts on demand and only creating the exact number needed, it minimizes waste and reduces the carbon footprint of the manufacturing process. However, there is a risk of supply chain disruption or the availability of raw materials. To mitigate this risk, manufacturers can develop strategic partnerships with suppliers to ensure the availability of materials and reduce supply chain risks.

    New Materials

    Additive manufacturing enables the use of new materials that were previously difficult or impossible to work with. For example, 3D printing allows for the creation of complex geometries and shapes that traditional manufacturing methods cannot achieve. However, the use of new materials can also result in material defects or failures. To mitigate this risk, manufacturers should test and validate new materials before using them in production, ensuring that they meet the required performance standards.

    In conclusion, additive manufacturing is set to revolutionize the manufacturing industry by offering customized, efficient, and sustainable solutions. However, as with any technology, there are also risks associated with its use. Manufacturers must be aware of these risks and take appropriate measures to mitigate them. With its many benefits, additive manufacturing is undoubtedly the future of manufacturing.

  • Additive Manufacturing for The New Space Age

    Additive Manufacturing for The New Space Age

    The space industry is a great field for new technology development. The challenges such as lightweight and stronger components with the demand for higher trust and lighter rockets that can reach mars propel the demand for more advanced components. Emerging technologies are almost always initiated in space or defense industries because the demand for the better originates in these industries either by war or competition in the industry. Additive Manufacturing is also incepted in the aerospace industry and there are several great examples Large rockets, aircraft engines, satellites are all requires lighter and stronger parts. and the good thing is that the production volume for industrialization of these components way lower than the automotive industry. This makes these platforms a disruptive opportunity.

    Additive manufacturing provides faster cycle time and leaner production of testing components for a space platform program. This both the design cycle of the components and the overall schedule of the development programs. Another advantage of additive manufacturing for space components is the reduction of complexity. Additive manufacturing enables the complexity of the component while reducing the complexity of the overall realization of the component. Combining several sub-parts into a combined assembly that can be built by additive manufacturing. We will go over some of the recent advancements that are developed by different NASA research centers. We will go over Rocket engine component examples that are developed with additive manufacturing technology such as injectors, turbopumps, combustion chamber and more. These advancements are great examples and paves the way to new space age for reaching Mars and beyond.

    Rocket Engine Injectors

    Rocket Engine fuel injectors are simple but one of the most critical of a rocket engine because it defines the theoretical performance of the rocket nozzle. A well-designed injector enables efficient burning of the propellant. In addition to that, injectors help to reduce the thermal loads on the nozzle by cooling the internal nozzle surface with fuel. Injectors can be made by drilling small holes with a designed pattern that fuel and oxidizers travel. The holes break the fuel into small droplets, smaller the droplets burned easily and the efficiency of the combustion increased. The holes are can be drilled in conventional ways but it is costly when compared to additive manufacturing. Rocket engine injector successfully tested at NASA Glenn research center Rocket combustion lab with a benefit of lead time from 1 year to 4 months and 70% less cost. The main cost out opportunity is to reduce the number of parts. The additive injector has 2 parts, while its conventional version has 115 parts. This is a disruptive reduction for both cost, program execution, and simplification of the supply chain.

    Rocket Engine Turbopumps 

    Rocket Engine Turbopumps produce high-pressure propellant to feed rocket engine combustion chamber. These pumps are designed with turbo-machinery principles and the design of these components is as hard as a jet engine yet a well-designed turbopump can deliver 70–90% efficiency. This particular turbopump makes 90000 revolutions per minute (RPM) to pump propellant. NASA has developed a turbopump in 2015 for liquid hydrogen, which is an ideal propellant for space missions but it is pumped at -240 Celcius. Rocket engine turbopump has 45% fewer parts. Combining several parts into one complex additive part dramatically reduces both costs and the weight of the component. On top of that reducing the number of parts simplifies the supply and realization of the hardware.

    This rocket engine fuel pump has hundreds of parts including a turbine that spins at over 90,000 rpms

    Gimbal Cone

    There are many methods to change the exhaust direction of the rockets. One of the methods is to use a gimbal system. A gimbaled nozzle tilts the engine nozzle in the proper direction. Below Gimbal cone made of titanium at ORNL, The process used for this component is Electron Beam Melting. When compared to investing casting or other conventional manufacturing methods. The manufacture of titanium components like this gimbal has a great potential to reduce costs as well as lead time and overall weight of the component. Titanium alloys are expensive yet they provide lightweight and strong components. Especially Ti-6Al-4V is a great alloy for rockets, jet engines, and satellites. Of Course, there are challenges like material properties and how are these are changing with the variation of process features. Powder Process microstructure relations are complex and need to be investigated.

    Rocket Engine Combustion Chamber 

    Rocket fuel and oxidizer flow in to combustion chamber with the help of turbo pump since the pressure inside the combustion chamber is extremely high. The combustion chamber mixes oxidizer and the fuel. The temperatures inside of the combustion chambers is over 2750 Celcius. This is far more than the melting temperature of copper alloy. In order to protect the chamber from melting during this extreme operation, It is being cooled by the extremely low temperature (-173 Celcius ) gas circulation inside the 200 tiny channels. These channels can only be manufactured by additive technology. It takes more than 10 days to build this rocket component but it is way faster than to manufacture it with conventional ways. Copper is a good heat conducter and this makes it a great match for this application. However, it makes it hard to melt with a laser scan. Overcoming these obstacles is not easy but enables game change rocket engines.

  • Additive Manufacturing: An opportunity in a VUCA World

    Additive Manufacturing: An opportunity in a VUCA World

    In the future, we will remember 2020 as a good example or even the start of a Volatile, Uncertain, Complex, and Ambiguous world. VUCA is a term generally used by the military to define war situations. As most of the leadership traits taken from the military, VUCA is also coming from the military. Military trains soldiers for the worst-case scenario where people fight and suffer. Parallel with that best leadership skills and concepts that are leveraged to the business world comes from the military. It has been started to be used in post-cold world era. Globalization and global networks and a more connected world now show us what it really means. 2020 feels like the definition of what is VUCA. If you want to put this term into a dictionary, put it like that:

    VUCA : World in 2020

    World Health Organization is notified on COVID-19 on January 7, and the global economy comes to a risk of recession in 5 months. Travel, Aviation, and Retail industries are the ones that are heavily impacted. Think about the supply chain supporting all of the products and services in these industries. Suppliers in these complex networks are shrinking and going out of business right now.

    Shutting down economies and slowing down global trade disrupted supply chains dramatically. With the reduced demand rate in especially in aviation industry tier 1–2 suppliers started to shrink down their operations. Suppliers are very similar to muscles in the human body. When the economy shrinks like when you stop eating, your muscles shrink first. This is what happens to suppliers right know. They are shrinking and going out of business. As all bodybuilders know well enough, it is tough to rebuild these muscles. A supplier may have a history of 10–20 years, and it can go out of business in a crisis like this in 3–6 months or big suppliers can downsize their operations and shut down their not all but some of the shops. Recovering these muscles is not easy. It is not possible to gain back in 3–6 months what you have built-in 10–20 years.

    OECD data shows that 70% of global trade depends on global supply chains. This is where the global economy drives its power. On the other hand, this network business is so connected and involved that its prone to the butterfly effect. Sometimes weakness may be the result of strength. Viruses like COVID-19 spread much faster in a globally connected network of people.

    Is COVID-19 a Black Swan or an event gets us prepared to the new normal. VUCA is becoming the new normal. This is not only a case for COVID-19. There would be other global changes that have a considerable risk of disrupting the global supply chain by looking at the news from the first month of 2020

    • January 2: Bushfires in Australia
    • January 2:Iranian General Soleimani killed in a US drone strike.
    • January 7: The WHO is notified new coronavirus
    • January 8: Iran launched ballistic missiles to bases in Iraq.
    • January 15: Trump Impeachment Inquiry
    • January 22:Locust outbreak in Kenya
    • January 31: UK Exists EU.

    This was just the first month of 2020 in the 2019 global economy impacted by trade wars. Original equipment manufacturers cannot respond to these changes and quickly adapts to the new normal with a conventional supply chain. There will be disruptions in the global supply chain more than ever because of global, economic, geopolitical, and technological abrupt changes, natural disasters, or competitive strategies.

    Additive manufacturing, aka 3D printing, can help to balance the impact of global disruptions like COVID-19. How? Why?

    Additive manufacturing is a new tech that enables manufacturing of parts, even assemblies layer by layer from a computer file by consumable materials. The primary advantage of this technology is flexibility and complexity when compared to conventional methods.

    Oak Ridge National Laboratory

    You can check the above photo from ORNL (Oak Ridge National Laboratory) to understand what are the possibilities with additive manufacturing. The best thing is you do not need tooling for the manufacturing of different components. In conventional manufacturing, there is a set of tooling to enable the manufacturing of the components. For casting, a model and core needed to form casting mold for machining, a holder, and fixtures required for manufacturing. The worst thing is when you need to design the fixtures, tools, and molds before you can manufacture your actual part. It takes time to complete all of the tools and fixtures, and this is why conventional manufacturing is not as agile and flexible as additive manufacturing since there is no need of tools and fixtures for additive manufacturing, it is much easier to build several different parts and products with a single machine without the need of complex tooling.

    A conventional manufacturing shop has engineers technicians to support all of the efforts related to design, manufacture, and maintenance of tooling manufacturing and actual part manufacturing. In additive manufacturing shops, an operator can easily run 4–5 Additive manufacturing machines. An engineer can prepare part files that are needed for these machines. The good thing is when you have a part file that is capable of delivering the requirements of the part/product. The only need is to store this file and consumables. There is no need to store fixtures, tools, or there is no need to hold an inventory. It is possible to manufacturing when there is demand. It is possible to manufacture other parts when there is no demand for the work in hand. An additive manufacturing shop can be a medical device factory, a rocket part factory and automobile part factory at the same time or shift between industries with very little disruptions.

    Think about what we are going through right now. COVID-19 heavily disturbing century-old industries. A manufacturing supplier working in the aviation industry cannot survive this crisis. On the other hand, an additive manufacturing supplier can simply shift to the manufacturing of respirator parts for medical device OEMs instead of Aviation OEMs. It is also possible to continue to manufacture aviation components when the industry recovers from COVID-19 travel restrictions…

    Charles Darwin

    Think about a world that is not possible to plan for the next 6 months. Your production volume may change because of many reasons that are not in your control. An additive manufacturing shop is at least 10 times more flexible than a conventional manufacturing shop. Business with Vision to tackle challenges, Understanding to see the opportunities and Courage to take action and Adapt, it will thrive in a Volatile, Uncertain, Complex, and Ambiguous world.

    Vision, Understanding, Courage, and Adaptability are remedies to the VUCA world, while additive manufacturing is a remedy to the supply chain in a VUCA world.
