Advantages Of 3D Printing:
- Complex geometry possible with 3D printing
- Develop a printing plan according to the use of the product
- The fastest lead time
SLA, or light curing molding technology, refers to a molding method in which liquid photosensitive resin is irradiated with ultraviolet light to undergo polymerization reaction to solidify layer by layer and generate a three-dimensional entity. The workpiece prepared by SLA has high dimensional accuracy and is the earliest commercialized 3D printing technology.
Machining accuracy is 0.05~0.1mm, the recommended minimum wall thickness is ≥0.4mm, and the minimum aperture is ≥0.8mm
SLS (Selective Laser Sintering)
Compared with SLA process, the product has high strength, good temperature resistance and smooth surface. It is often used for product functional verification, and can replace the injection parts in the early stage of R & D（ Nylon and Nylon glass fiber)
The machining accuracy is 0.15 ~ 0.2mm. It is recommended that the minimum diameter of the hole be ≥ 1.5mm and the minimum wall thickness be ≥ 0.6mm
FDM is the melt layering technology, which uses high temperature to melt the material, extrude it into filaments through the print head, and build it on the component platform. FDM is the simplest and most common 3D printing technology, usually applied to desktop 3D printing equipment.
SLM（Selective Laser Melting）
SLM, the selective laser melting molding technology, is currently the most common technology in metal 3D printing molding. It uses a finely focused spot to quickly melt the preset metal powder to directly obtain any shape and complete metallurgical bonding parts, and the resulting production density can reach More than 99%.
