SLS technology uses polymer powder materials. After spreading a layer of powder in the molding cylinder, the scanning of the molding area is carried out using a laser beam. The scanned powder is melted and sintered layer by layer until it forms the final product, while the powder that is not scanned provides support until the completion of the process. SLS 3D printing technology can print PP materials and various PP composite reinforced materials. Compared with other printing technologies such as FDM and photo-curing, SLS printing technology has the advantage of small anisotropy in the XYZ three directions of the printed part, and no need for support structures.
PP materials and various composite materials have good comprehensive performance and lower printing costs. They are applied in multiple industries and fields. Now they can be rapidly prototyped using laser sintering 3D printing technology, which can reduce costs and improve efficiency in medical support equipment, new product design and development, and small batch customization production. It can help companies reduce costs and increase efficiency, and provide accurate medical services to patients.

Now let's take a look at the applications of SLS printing PP:
Because PP materials are particularly stable in water, with a water absorption rate of only 0.01%, they are very suitable for making various complex and irregular pipelines and joints.
PP materials have good comprehensive mechanical properties, especially good toughness and secondary shaping ability, and can be widely used in the medical rehabilitation field. The fixed finger brace is specifically used for finger, palm, wrist joints, and bone injuries or postoperative fixation.
PP fiberglass composite materials, with their advantages of light weight and good toughness, are also widely used in the automotive industry. At present, most of the interior and exterior parts of cars are made by PP powder.
