Laser Sintering and Milling Working Together | MoldMaking ...

Laser sintering and milling can be performed on one machine, providing additive machining in addition to more traditional, subtractive milling. Traditional machines start with a piece of steel and mill, drill and grind it to get to the finished piece. However, the hybrid process starts with nothing but a base plate and a bucket of metal powder.
