SLM process is also known as selective laser melt forming technology. Its principle is that the metal powder is completely melted under the thermal action of laser beam and formed after cooling and solidification. SLM printable materials are stainless steel, aluminum alloy, die steel, titanium alloy etc. With high precision and good strength, metal printing has advantages for complex parts, with the precision up to plus or minus 0.1mm. The printed parts can be directly used as functional parts.

SLA process is also known as light curing process. Its principle is to take advantage of the sensitivity of photosensitive resin to ULTRAVIOLET light to control the resin curing and forming at a specific position. SLA printable materials are photosensitive resin, high toughness resin, transparent resin, high temperature resistant resin and soft plastic resin etc. The photosensitive resin material has high precision and is often used to verify the appearance parts and structural parts with high cost performance. The resin material has good surface quality and is easy to be polished, painted, electroplated and for other post-treatment processes. Precision is generally in the plus or minus 0.1-0.2mm. thread structure is printable. Disadvantages are: the material is brittle, temperature and wear resistance is not very good.

SLS process is also known as selective laser sintering process, which is based on the principle of sintering the specific position of the powder through the laser.
SLS printable materials are nylon and nylon with glass fiber. There are white nylon and black nylon. Nylon with glass fiber is brown. Nylon and nylon with glass fiber’s strength and toughness are relatively good, can be directly used for functional parts; Disadvantages are that the surface is relatively not very smooth, and has a sense of granularity.

FDM process is also known as fused deposition modeling process, which is based on the principle that the nozzle is used to heat and melt the filamentous material, and then the plastic is cooled and formed in a specific location. The printable materials of FDM include PLA, ABS, PETG, PEEK, PP, PC and carbon fiber. PLA and ABS have strong mechanical properties and are not easy to be deformed. Disadvantages are: slight lack of precision, obvious surface lamination.
