Matthew Gailey, EMD Chemicals (an affiliate of Merck KgAA)

The development and refinement of plastics additives or laser sensitivity enable high-contrast marking of plastics in combination with a suitable laser beam. Here’s how to choose the right additives for the job. Thanks to lasers, manufacturers can write characters and images on any plastic parts you can think of, no matter the shape or surface structure. Expiration dates on bottle closures, serial numbers on technical parts, or marking items with an ID number or even indestructible bar codes – it’s all possible with materials advances and lasers. The NIR laser 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...
