Laser Metal Fusion Wiki

Selective laser melting slm also known as direct metal laser melting dmlm or laser powder bed fusion lpbf is a rapid prototyping 3d printing or additive manufacturing technique designed to use a high power density laser to melt and fuse metallic powders together.

Selective laser sintering sls is an additive manufacturing am technique that uses a laser as the power source to sinter powdered material typically nylon or polyamide aiming the laser automatically at points in space defined by a 3d model binding the material together to create a solid structure it is similar to selective laser melting. To many slm is considered to be a subcategory of selective laser sintering. Laser metal fusion is capable of generating fully functional metal prototypes and production parts using sisma 3d metal printers. It uses a variety of alloys which allow the prototype to be made from the same material as production components.

This is where the laser metal fusion technology focuses. Sisma laser metal fusion lmf technology utilizes a high power laser beam to realize 3d printed parts through the fusion of thin layers of metallic powder. Direct metal laser melting dmlm is an additive manufacturing process that uses lasers to melt ultra thin layers of metal powder to build a three dimensional object. Laser metal fusion is an additive manufacturing method where a workpiece is built up gradually in a powder bed.

Everything starts from the designer. One thing is designing and producing a ring another is exploiting a 3d cad design software to the highest levels being able to create unique items not duplicable recognizable objects of an upscale style. Sisma lmf 3d printers are able to directly produce finished prototypes pieces of jewelry and accessories with highly precise and elaborate details exactly the way you envision. To do so a laser melts down the metal powder in material layers precisely at the points specified by the component s cad construction data.

The two are instantiations of the same concept. In contrast laser metal fusion lmf or the process commonly known as metal 3d printing is a powder bed based laser fusion process that converts 3d digital data into a physical part built up layer by layer. Objects are built directly from an stl file generated from cad computer aided design data. The system with its 100 100 mm build volume and its 200 w laser has uses in research given its compact footprint open parameters high resolution printed parts high processing speed and the simple and intuitive operation.
