Metals are considered one of the most complex elements present in nature. Several metals can be used for making jewelry or other precious ornaments. What we want to imprint something on the metal. For this, the technique commonly practiced is the 3d metal printing machine. The technique is nowadays popular in the U.S. it is based on laser technology that uses powdered metals. The technique used in this machine works on the same principle that is shared by the laser sintering. Laser sintering is a high-powered laser that selectively binds together particles on a bed made from powder. In contrast, the distribution of metallic powder in layers is done through a machine.
How does the machine work?
Firstly a thin layer of metal powder is speeded on the floor then a laser beam is used to fuse the powder as it scans it. After that, one solid layer of the object is made, and a second layer using a recoater is made. Its platforms in the machine move downwards by 50 microns to 200 microns.
What does it make?
It creates parts with shapes and internal structures that could not be cast or machined. Metal 3D printing can create parts within parts for designing the most complex structures. The technique is costly as the machine is costly. Still, price rates vary according to the volume available for the 3D model, complexity, and the finishing it provides while embedding the things.
The machine is three times stronger than steel and made with some conventional techniques.
