Easy Technology Questions and Answers

  1. Which manufacturing process is also known as additive manufacturing?

    3D printing

    Additive manufacturing builds an object layer by layer from digital instructions, which is why 3D printing is its familiar name. Subtractive processes such as milling instead remove material from a larger piece.
