SLS 3D Printing uses a high-power laser to sinter and fuse the polymer powder together and build solid parts layer by layer, which can produce parts that are strong, durable, finely detailed, and flexible. SLS printer manufacturers are delivering various types of SLS printers to the market and boast that selective laser sintering outperforms injection molding, so in this article, let's learn and discover the best SLS printers of 2022.

Part 1. Why Choose SLS

Before talking about which are the best SLS 3D printers in the industry, there are some reasons that SLS is worth considering when choosing the right manufacturing technology to create functional parts.

1. High quality products. SLS can create parts with high mechanical properties and precision that can reach end-use quality.

2. Support-free. SLS printing doesn't need supports in the most cases, which means it is suitable for design and produce parts with complex shapes and geometries.

3. Sustainable. Much of the loose powder in depwodering process can be recycled, which means materials and maintenance cost is lower.

4. Material flexibility. Compared with SLA 3D Printing, there are a wide range of materials such as PA, PPGB, HP, etc., while blending materials is available according to specific requirements on product toughness.

5. Multiple post-processing available. To get detailed surfaces and unique colors, SLS printed parts can be processed with sand blasting, grinding, and painting, etc.
