1.What is the strongest 3D printing technology? Polycarbonate (PC) Polycarbonate (PC) delivers high tensile strength along with high impact and heat resistance. It's widely seen as one of the strongest 3D printing filaments. 2.Why is SLS printing so expensive? Because the SLS technology requires a high-powered laser, a high level of precision, and tight control throughout the printing process, even the cheapest SLS printer is more expensive than most fused deposition modeling (FDM) and many stereolithography (SLA) printers. 3.What are the disadvantages of SLS manufacturing? Higher waste than other additive manufacturing Unfortunately, SLS does produce some waste since the powder in the chamber is preheated so that it will sinter with minimal exposure to the laser. This can cause particle grains in the loose powder bed to partially fuse which compromises its quality for reuse.3D printing is a manufacturing process that uses digital files to create physical objects. It works by layering materials together until the desired shape is achieved. The process can use a variety of materials, such as plastic, metal, and even food.Rapid prototyping is the process used to quickly create a physical model or prototype of a product design. It is used to test and improve product concepts before they go into production. 3D printing is often used as a rapid prototyping tool due to its ability to quickly create precise objects.SLA and SLS are two 3D printing technologies. SLA printing uses a liquid resin cured by a laser to create objects. SLS printing, on the other hand, uses powdered materials that are fused together by a laser to create the final product. Both technologies are used in rapid prototyping, product development and manufacturing in a variety of industries.● Resolution ● Appearance● Abrasion resistance ● Mechanical resistance
