Laser powder bed fusion is among the most widely used metal 3D printing processes.

In the LPBF process, the first step involves evenly applying a thin layer of powder material, ranging from 10 to 100 micrometers, onto the build plate using a coater. A directed laser beam then selectively melts the material. After the melting process, the build platform is lowered, and the cycle begins again. This method creates individual melt tracks that are placed next to each other, which together form a single layer. By stacking several of these layers, a complete component is formed.

The very thin layer thickness achieved in the LPBF process allows for high detail resolution in the components produced. This capability not only broadens the range of components that can be created beyond traditional manufacturing limits but also enhances the potential geometries that can be realized.

AconityMIDI+ offers a flexible approach to the additive manufacturing process. One of the main attractive concepts in MIDI+ is the ability to change the process chambers to use time efficiently. For maximum material flexibility and quality assurance, high-temperature preheating of up to 1000 ° C is possible. The AconityMIDI+ is equipped with the web-based control software AconitySTUDIO, allowing for remote access to all relevant process parameters and machine components.
