Stereolithography (SLA): Precision and Detail for Professionals

SLA printing is revered for its precision and ability to produce smooth, detailed prints. It’s particularly popular among professionals who require high-quality prototypes and intricate models.

• How It Works: SLA printers use an ultraviolet (UV) laser to cure and solidify liquid resin into the desired shape, layer by layer.
• Materials Used: They utilize photosensitive resins, which offer a range of properties like flexibility, transparency, and high strength.
• Advantages: SLA is known for its exceptional detail and smooth surface finish, making it perfect for intricate designs and complex geometries.
• Limitations: The cost of SLA printers and their materials is generally higher. Also, the resin requires careful handling and post-processing.

Selective Laser Sintering (SLS): For Durable and Complex Industrial Parts

SLS is a choice for professionals who need robust, functional parts. It’s commonly used in industries for creating prototypes, tools, and end-use parts.

• How It Works: SLS printers use a high-powered laser to fuse small particles of polymer powder into a solid structure, based on the 3D model.
• Materials Used: This technology primarily uses nylon powders, known for their strength and durability.
• Advantages: SLS doesn’t require support structures, allowing for more complex designs and moving parts. The parts produced are durable and suitable for functional use.
• Limitations: SLS printers are expensive and generally reserved for industrial use. The process also requires a higher level of expertise to operate and maintain.
