SLM, the acronym for Selective Laser Melting, is an additive manufacturing process that fabricates metal parts directly from a digital 3D CAD file to a physical part. The SLM 3D metal printing process employs melting the layers of fine metal powder using state of the art fibre lasers and growing the part layer upon layer. With the wide range of superior metal alloy powders, SLM metal 3D printing technology offers unparalleled possibilities to manufacture production grade prototyping metal parts with a substantial advantage on the cost and quick turn- around time.
It is the only technology to offer an open-ended software architecture to develop the system parameters for new material development by the users on their own. Combined with the path breaking innovations like the ‘bi- directional loader movement’ with a highly efficient system for monitoring and consumption of the inert gas system and features like the dual lasers and the revolutionary ‘Hull – Core’ technology makes SLM unique in the class of metal 3D printing.
These innovative features have established SLM metal 3D printer parts to be comparable to the cast components in terms of repeatability, accuracy and 100% density – assuring the homogeneous property in every part build. SLM offers standard alloys of Aluminium, Cobalt Chrome, Titanium, Stainless Steel and other popular alloys making it the most sought metal 3D printing technology in the industry.
How SLM Metal 3D Printing technology works?
The pre-processing software slices the 3D CAD data into 2D cross sections with relevant support structures for overhangs and voids.
The bi-directional re coater spreads the fine metallic powder fed from the automated feeder on to the heated build platform to initiate the build.
State of the art fibre lasers heat up the cross section of the 2D sliced file and creates a melt pool to melt and fuse the metal powder – ensuring the homogeneity of the part. The same process repeats for the entire part build layer-by-layer.
