why you might want to 3D print steels 3D printing tool metal is an established approach which facilitates complicated internal structures that cannot be otherwise machined and has been experiencing strong growth in recent years. Such structures are critical for establishing precise thermal control during high energy applications which correspondingly enables greater accuracy by reducing part warpage during temperature change, exceptional cycle times and part lifetime in a range of production industries: polymer injection molding is a certainty, but this probably also has applications in weaponry, engine design and some other aspects of aerospace.
