After 35 years of rapid development, 3D printing has saturated the market with various solutions. For beginners, determining which technology is most suitable can be difficult, so purchasing decisions are usually based on two factors: availability and price. Most beginners choose between FDM (Fused Deposition Modeling) and SLA (Stereolithography), which are the most common and affordable 3D printing technologies. In contrast, SLS (Laser Sintering) seems less affordable and more expensive, deterring 3D printing novices. But is this really the case?
SLS technology uses laser light to fuse powder materials. The powder is spread and fills the entire 3D printing space inside the machine, eliminating the need for support materials and allowing the mechanical structure to be printed as a single piece. Because the object is molten and polymerized rather than glued, as long as it is cleaned properly, the finished product will not shed powder or disintegrate during use. Although the equipment is more complex and costly, it offers superior functionality. (Further reading: Introduction to SLS 3D Printing Technology )
Shane Mahon works for an IT company and is a product designer. He loves cycling and often comes up with ideas for bicycle parts, trying to use 3D printing to prototype the parts he wants.
He experimented with various 3D printing technologies such as FDM , SLA , and SLS . Through extensive research and component testing, he discovered that Sinterit Lisa SLS 3D printing could also meet the manufacturing needs of beginners. SLS 3D printing not only produces objects with high hardness, but also allows him to perform assembly tests with precise mechanical structures. The operation and post-processing are also easy, saving a lot of time and allowing him to focus on testing and modeling development.
FDM hot-melt stacking technology is the most common due to its affordability. Because of its small size and ease of operation, it can be quickly adopted by small and medium-sized enterprises, while requiring minimal post-processing and waste disposal.
SLA Photopolymerization technology is ideal for printing small objects, figurines, shaped objects, jewelry, etc. with intricate details; the finished product has a smooth surface and can display complex textures, with less physical and mechanical complexity compared to the other two technologies.
SLS laser powder sintering is relatively difficult to operate and expensive, but it has the best mechanical and functional prototype applications, a matte surface, does not require support, and the finished product is relatively strong and durable.
Each of the three technologies has its own advantages, disadvantages, and characteristics. With proper design and operation, the desired results can be achieved.
