Powder characteristics are very important for successful powder bed fusion.
Renishaw make sure that the powders supplied for their additive manufacturing systems are of the highest quality.
A technician works with this 3D model to properly orient the geometry for part building and adds supports structure as appropriate.
Once this "build file" has been completed, it is "sliced" into the layer thickness the machine will build in and downloaded to the DMLS machine allowing the build to begin.
This technology is used to manufacture direct parts for a variety of industries including aerospace, dental, medical and other industries that have small to medium size, highly complex parts and the tooling industry to make direct tooling inserts. The technology is used both for rapid prototyping, as it decreases development time for new products, and production manufacturing as a cost saving method to simplify assemblies and complex geometries.) of 250 x 250 x 325 mm, and the ability to ‘grow’ multiple parts at one time, The Northwestern Polytechnical University of China is using a similar system to build structural titanium parts for aircraft.
On September 5, 2013 Elon Musk tweeted an image of Space X's regeneratively-cooled Super Draco rocket engine chamber emerging from an EOS 3D metal printer, noting that it was composed of the Inconel superalloy.
Inside the build chamber area, there is a material dispensing platform and a build platform along with a recoater blade used to move new powder over the build platform.The technology fuses metal powder into a solid part by melting it locally using the focused laser beam.Parts are built up additively layer by layer, typically using layers 20 micrometers thick.DMLS produces strong, durable metal parts that work well as both functional prototypes or end-use production parts.The DMLS process begins with a 3D CAD model whereby a file is created and sent to the machine’s computer program.
Additionally, DMLS allows for more rigorous testing of prototypes.
