The basis for the dental SLM (Selective Laser Melting) manufacturing process is the digital design data from dental frameworks, which were created with the help of dental scanners and design software - in the dental industry, 3Shape, exocad or Dental Wings are usually used. These designs - often in the form of STL data – are digitally transmitted to us from the dental laboratory via our upload tool or via the order entry on the website.
After a random feasibility check of the orders, the data is prepared for the actual production process. This means, the digital construction is virtually divided into individual layers and transmitted to the dental laser system for production.
Before the laser process can start, the storage container is filled with laser powder. A metal plate - the so-called manufacturing platform - is inserted into the cabin space of the laser system, on which the support structure (support pins) is first built in the process and later the frameworks. The metal powder is applied in layers, therefore the manufacturing platform is lowered by the desired layer height (usually approx. 30 µ).
Then the first layer of fine-grain metal powder is applied to the platform by means of a coater.
