The use of ultraviolet (UV) laser focused on the surface of liquid photosensitive resin, according to the layered cross-sectional trajectory scanning, so that the resin instant curing molding, layer by layer for three-dimensional parts
Mainly liquid photosensitive resin (such as ordinary resin, toughness resin, high temperature resistant resin, transparent resin, etc.), the material is relatively single, mainly high molecular polymer
The core advantages of SLA process focus on "high precision, high surface quality, rapid prototyping", especially suitable for scenes with strict requirements on appearance and details.
The use of high-power laser (mostly infrared laser) focused on the powder material (plastic/metal/ceramic) surface, according to the layered trajectory scanning, so that the powder particles in the laser high temperature sintering (fusion) molding, unsintered powder as a support
Mainly powdered materials, covering plastics (nylon PA12, PA11, TPU, etc.), metals (stainless steel 316L, titanium alloy TC4, etc.), ceramics (alumina, zirconia, etc.)
The core advantage of SLS process is "unsupported complex structure molding, excellent material mechanical properties, wide application scenarios", especially suitable for functional parts manufacturing and small batch production.
