“An MMT understanding allows us to appreciate that there would be no financial impediment for a government building national industries, funding research and development, providing first-class universities and apprenticeship training and the rest. If a nation with its own currency slides into oblivion by closing its manufacturing sector, cutting career public sector jobs and relying on low-paid and precarious service sector jobs for employment creation, then that has little to do with running external deficits, and everything to do with political choices.”

“FDM (Fused Deposition Modeling) printers There is no hard and fast classification of the FDM 3D printers Cartesian 3D Printers: These are the most common type, operating on a straightforward Cartesian coordinate system with linear rails guiding movement along the X, Y, and Z axes. They are recognized for their simplicity and reliability. Delta 3D Printers: Delta printers employ a triangular configuration of three arms attached to moving carriages at the printer's apex. The print head hangs from these carriages, executing precise movements to craft the intended object. Delta printers excel in speed and consistency, particularly in producing tall items. CoreXY 3D Printers: CoreXY printers utilize a distinctive belt-driven mechanism to maneuver the print head across the X and Y axes. This design separates the print head's motion from that of the build platform, resulting in swifter and more accurate prints. Enthusiasts favor CoreXY printers for their speed and precision. Polar 3D Printers: Polar printers feature a circular build platform and a print head that moves both radially and vertically. This configuration facilitates continuous rotation of the print bed, enabling the creation of objects with intricate geometric shapes. Polar printers are commonly employed for crafting artistic and sculptural pieces. SCARA 3D Printers: SCARA (Selective Compliance Articulated Robot Arm) printers utilize a robotic arm mechanism to navigate the print head in a two-dimensional plane. This design offers rapid and precise movement, making SCARA printers ideal for producing small, intricate objects with exceptional accuracy. Each variant of FDM 3D printer has its own strengths and is tailored to diverse applications, spanning from hobbyist endeavors to industrial-scale manufacturing.”

“What is Directed Energy Deposition in 3D Printing Directed Energy Deposition (DED) is a term that encompasses technologies involving semi-automated powder spraying and wire welding for manufacturing. When applied to 3D shapes, DED is considered an additive manufacturing process. It typically results in a rougher surface compared to Powder Bed Fusion, due to the larger bead sizes and coarser powder used, which often necessitates additional machining. DED systems generally fall into two categories: deposition systems and hybrid systems that combine a DED head with traditional machining equipment. The main advantages of DED include faster deposition compared to powder bed fusion 3D printing and the ability to create functionally graded material structures, especially when using powder. Additionally, since the feedstock and energy source move together, DED systems can manufacture very large structures, unrestricted by the size limitations of a build box. In some cases, DED can be more effective than traditional manufacturing methods or powder bed fusion. Most DED systems consist of a deposition head that uses either wire or powder and is mounted on a robot or CNC system. Common energy sources include Arc, Laser, or Electron Beam, with lasers being the most frequently used for powder feedstock. The process involves offline programming to generate a tool path from a sliced CAD file. The motion system then follows this path, depositing material in layers to build the desired shape. DED is compatible with a variety of weldable alloys, such as aluminum, steel, nickel, and titanium. Depending on the chosen alloy and process, shielding gas may be applied locally or within an enclosed environment.”

“What is Binder Jetting in 3D Printing The binder jetting 3D printing process involves depositing an adhesive binder onto thin layers of powdered material. These materials can be ceramic-based, like glass or gypsum, or metal, such as stainless steel. During the printing process, the 3D print head moves over the build platform, depositing droplets of binder, similar to how a 2D printer applies ink to paper. Once a layer is completed, the powder bed lowers, and a new layer of powder is spread over the build area. This layering continues until the entire object is printed. After printing, the parts are in an unfinished, or "green," state and require further post-processing. To enhance the mechanical properties of the parts, an infiltrate substance, such as cyanoacrylate adhesive for ceramics or bronze for metals, is often added. Another method involves placing the green parts in an oven to sinter the material grains together. Interestingly, the term "3D printing" originally described a process that used inkjet-like heads to deposit binder material onto a powder bed layer by layer.”
