Additive Manufacturing: The Laser Source Is Critical

Dick Rieley, Ophir-Spiricon LLC

Laser beam power, spot size and focal point must be measured and controlled to produce parts to specification through 3-D printing. Laser-based additive manufacturing (AM) involves the deposition of a precise amount of material in a layer- by-layer process to produce components of specific measurements and physical properties. Instead of milling a workpiece from a solid block, AM builds up components layer by layer using materials that are available in a powder form. A wide variety of materials from plastics to metals and even composite materials can be used. The process is...Read full article

    additive manufacturing
    Additive manufacturing (AM), also known as 3D printing, is a manufacturing process that involves creating three-dimensional objects by adding material layer by layer. This is in contrast to traditional manufacturing methods, which often involve subtracting or forming materials to achieve the desired shape. In additive manufacturing, a digital model of the object is created using computer-aided design (CAD) software, and this digital model is then sliced into thin cross-sectional layers. The...
