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.
(1) Extremely low temperature drift (over 8 hours long-term offset drift ≤ 30 μrad);
(2) Extremely high repeatability (≤ 3 μrad);
(3) Compact and reliable;
3D scan heads provided by CARMANHAAS offers ideal solutions for high end industrial laser applications. Typical applications include cutting, precise welding, additive manufacturing (3D printing), large scale marking, laser cleaning and deep engraving etc..
CARMANHAAS is committed to offering best price/performance ratio products and working out the best configurations according to customers’ needs
