3D printing technology is a new word in recent years for the civilian market. In fact, in professional field, it has another name -- rapid prototyping technology.
Rapid prototyping technology is also called Rapid Prototyping Manufacturig (RPM).
FDM technology is less polluted, and materials can be recycled for forming small and medium-sized workpieces.
SLM printer laser selective melting forming technology (SLM) is an advanced manufacturing technology of laser augmentation based on prototype manufacturing technology.
3D printing, also known as 3D printing (3DP), is a kind of cumulative manufacturing technology, that is, rapid prototyping technology of a machine, it is a digital model file based.
Three-dimensional objects are made by printing layers of adhesive materials, such as special powders, metal powders or plastics.
