SLM Optical System supplier china 200W-1000W
Laser metal 3D printing technology mainly includes SLM (laser selective melting technology) and LENS (laser engineering net shaping technology), among which SLM technology is the mainstream technology currently used. This technology uses laser to melt each layer of powder and produce adhesion between different layers. In conclusion, this process loops layer by layer until the entire object is formed. SLM technology overcomes the troubles in the process of manufacturing complex-shaped metal parts with traditional technology. It can directly form almost completely dense metal parts with good mechanical properties, and the precision and mechanical properties of the formed parts are excellent.
Compared with the low precision of traditional 3D printing (no light is needed), laser 3D printing is better in shaping effect and precision control. The materials used in laser 3D printing are mainly divided into metals and non-metals。Metal 3D printing is known as the vane of the development of the 3D printing industry. The development of the 3D printing industry largely depends on the development of the metal printing process, and the metal printing process has many advantages that the traditional processing technology (such as CNC) does not have.
In recent years, CARMANHAAS Laser has also actively explored the application field of metal 3D printing. With years of technical accumulation in the optical field and excellent product quality, it has established stable cooperative relations with many 3D printing equipment manufacturers. The single-mode 200-500W 3D printing laser optical system solution launched by the 3D printing industry has also been unanimously recognized by the market and end users. It is currently mainly used in auto parts, aerospace (engine), military products, medical equipment, dentistry, etc. -
3D Galvo Scanner Head and Protective Lens for SLS optical system in china
SLS Printing uses selective CO₂ laser sintering technology which sinters plastic powders(ceramic or metal powders with binding agent) into solid cross-sections layer by layer until a three-dimensional part is built. Before making the parts, need to fill the build chamber with nitrogen and rise the chamber temperature. When the temperature is ready, a computer controlled CO₂ laser selectively fuses powdered materials by tracing cross-sections of the part on the surface of a powder bed and then a new coat of materiel is applied for the new layer. The working platform of the powder bed will go one layer down and then the roller will pave a new layer of the powder and the laser will selectively sinter the cross-sections of the parts. Repeat the process until the parts completed.
CARMANHAAS could offer customer Dynamic optical scanning system with High speed • High precision • High quality function.
Dynamic optical scanning system：means front focusing optical system, achieves zooming by a single lens movement, which consists of a moving small lens and two focusing lenses. The front small lens expands the beam and the rear focusing lens focuses the beam. The use of the front focusing optical system, because the focal length can be elongated, thereby increasing the scanning area, is currently the best solution for large-format high-speed scanning. Generally used in large-format machining or changing working distance applications, such as large-format cutting, marking, welding, 3D printing, etc. -
Stereolithography 3D SLA 3D Printer for UV Laser Additive manufacturing Processing
SLA(Stereolithography) is an additive manufacturing process that works by focusing an UV laser on to a vat of photopolymer resin. With the help of computer aided manufacturing or computer aided design(CAM/CAD) software, the UV laser is used to draw a pre-programmed design or shape on to the surface of the photopolymer vat. Photopolymers are sensitive to ultraviolet light, so the resin is photochemically solidified and forms a single layer of the desired 3D object. This process is repeated for each layer of the design until the 3D object is complete.
CARMANHAAS could offer customer the optical system mainly includes fast Galvanometer Scanner and F-THETA scan lens, Beam expander, Mirror, etc. -
