vat photopolymerization 3d printing or vat photopolymerization additive manufacturing uses a vat of liquid photopolymer resin, out of which layer constructs the model layer. An ultraviolet (UV) light cures or hardens the resin as needed, while a platform moves the object being created downwards after each successive layer has been cured. The technique involves using…
Sheet lamination is additive manufacturing (AM) technique in which layer glues together thin sheets of material to produce a single component that can then be cut into a 3D item. Laminated object manufacture (LOM) and ultrasonic consolidation (UC) are sheet lamination techniques. It can laminate sheets of paper, polymer, and metal, but each requires a…
Powder Bed Fusion is a popular method for producing 3D printed parts. The process uses a high-powered laser to sinter powdered material into the desired shape. Typically, powder manufacturing companies made this powder from plastics and metals, although it can also include ceramics, glass, and other materials. Powder Bed Fusion process Direct metal laser sintering,…
Material Jetting (MJ) is a type of additive manufacturing that works similarly to 2D printers. A printhead (similar to those used in standard inkjet printing) sprays droplets of a photosensitive substance that solidifies under ultraviolet (UV) light, layer by layer, to form a component. The thermoset photopolymers (acrylics) utilized in MJ are liquid. What is…
Material Extrusion 3D Printing (also known as Fused Filament Fabrication or Fused Deposition Modeling) is a 3D printing method that uses thermoplastic filament to build three-dimensional objects. The filament is molten and driven out of the nozzle after being fed from a big coil through a moving, heated print head (extruder). The material is then…
Directed Energy Deposition: What It Is, What It Is Uses for, And Why It’s The past few years have seen enormous progress and interest in Directed Energy Deposition (DED). We have made much progress on all fronts in materials, device configurations, and methods. The cross-disciplinary collaboration between engineering, materials science, and plasma physics has produced…
Binder jetting is an additive manufacturing process that deposits a liquid binding agent over powder particles. This creates high-value, one-of-a-kind parts and tools made from metal, sand, ceramics, or composites. The technique involves laying down layers of material, creating a solid object one layer at a time. This utilizes a map from a digital design…
