1, SLA (Stereoscopic Light Curing)
SLA technology is known for its high precision and high surface quality. It uses laser or ultraviolet light of specific wavelengths and intensities to irradiate liquid photosensitive resin materials, solidifying them layer by layer and stacking them into three-dimensional solids. SLA technology has a wide range of applications in jewelry design, art production, biomedical and other fields. Its advantages include high molding accuracy, good surface quality, and the ability to produce complex structures. However, the cost of SLA technology is high, the requirements for the working environment are also high, and the strength and durability of the formed components are limited.
2, SLS (Selective Laser Sintering)
SLS technology is known for its applicability to various materials. It uses a laser beam to selectively sinter powder materials (such as nylon, metal powder, etc.) and layer by layer to form a three-dimensional solid. SLS technology is suitable for producing products with complex structures and high strength requirements, and therefore has a wide range of applications in fields such as automotive, aerospace, and mold manufacturing. Its advantages include a wide selection of materials, high strength of formed parts, and the ability to produce large-sized products. However, the cost of SLS technology is also high, and post-processing requires additional time and cost.
3, FDM (Melt Deposition Modeling)
FDM technology is currently one of the most popular 3D printing technologies. It uses thermoplastic materials (such as ABS, nylon, etc.) to melt and extrude, layer by layer stacking into a three-dimensional solid. FDM technology has advantages such as low cost, simple operation, and relatively wide material selection. It is widely used in fields such as prototype design, education, and small component manufacturing. However, the forming accuracy and surface quality of FDM technology are relatively low, and the printing speed is slow.
4, DLP (Digital Light Processing)
DLP technology is an emerging 3D printing technology that uses a digital projector to project images onto the surface of liquid photosensitive resin, solidifying and stacking them layer by layer into a 3D solid. DLP technology has advantages such as fast printing speed, high forming accuracy, and good surface quality. It is suitable for producing high-precision, high surface quality components and products. However, the cost of DLP technology is relatively high, and the requirements for equipment are also high.
