While there are different types of metal 3D printing machines, methods and processes, the overall production process is very similar. Below we give you an easy explanation of how metal 3d printing works.
As always, it starts with an innovative design. Our engineers make sure the 3D model design is optimized taking all possible considerations into account.
When the design is finished we start with filling the production chamber of the printer with an inert gas, argon for example. This will make sure oxidation of a particular metal powder is prevented. The chamber will then be heated to the optimal temperature.
Then the scanning process starts. The high power laser scanner of the 3D metal printer spreads a thin layer of metal powder over the build platform. The model is constantly scanned throughout the process, the metal particles are melted together until it's ready for the next layer. This makes the object fully solid. The process is repeated layer by layer until the object is completed.
When the final layers are fusioned, the chamber starts to cool down to room temperature. Excess metal powder will now be removed and in most cases a heat treatment follows while the part is still located on the build platform. The final stage is detaching the object from the build platform and now the piece is ready for any post-processing, if necessary.
