Selective Laser Sintering (SLS), the SLS process is similar to the three-dimensional light curing technology SLA, except that SLS usually uses infrared laser beams, and the material has also changed from liquid photosensitive resin materials to powder particles. Molecular materials.
There are many molding materials for SLS process, and it is easy to support, including a variety of powder materials with different mechanical properties and a variety of nylon mixed materials. Such as the mixed material of aluminum powder and nylon suitable for molds, the mixed material of carbon fiber and nylon with extremely light weight and strong mechanical properties, a variety of plastic mixed materials and ceramic materials. In theory, any fusible powder can be used to make products or models, so the choice of powder material is one of the main advantages of SLS technology.
With the continuous maturity of 3D printing technology and continuous breakthroughs in material application science, the printed plastic or metal parts can now be directly applied to automobile production. The working principle of 3D printing additive manufacturing gives it a unique advantage in the production of complex structural parts. That is to say, the more complex the shape and structure of the parts, the more advantageous it is to use 3D printing to manufacture, such as the spool valve box of the automatic transmission, planetary gear sets, etc.
Among them, airless tires made in 3D are still quite advanced. Airless tires with customizable treads, customizable cushions and "fuel tanks", lightweight but durable diamond wheels, forkless steering systems, etc. The motor and battery are cleverly hidden by the car shell.
