DescriptionSLA uses a laser to cure liquid resin layer by layer. It provides high accuracy and smooth surface finish, ideal for prototypes and small parts.MJF uses a powder bed fusion process with inkjet technology for rapid and precise printing of complex geometries, ideal for functional parts and low-volume production.SLS uses a laser to sinter powdered material layer by layer. It is suitable for durable, functional parts, often used for aerospace, automotive, and industrial applications.FDM uses thermoplastic filament, melted and extruded through a nozzle. It’s one of the most common and cost-effective methods, suitable for prototyping, low-volume production, and educational purposes.SLM is a metal powder bed fusion process where a laser melts metal powder to build parts. It’s ideal for high-performance, metal-based parts in industries like aerospace, medical, and automotive.
