The AconityMIDI is Aconity3D’s approach for a flexible production system. Equipped with an optional second process chamber, this system allows for parallelizing setup times while the main system is still producing. Additionally, process monitoring or high- temperature preheating of up to 1200 °C is also available for this system.

The AconityMIDI is also available as DUAL-Laser system for further maximized productivity.

Additionally, the AconityMIDI may be equipped with the unique Vacuum option and Micro-LBM configuration.


AconityMIDI is the ideal combination of flexibilty and productivity.

Aconity3D is one of the leading providers of in-process monitoring systems for laser-based 3D printing of metals (L-PBF).
The process monitoring tool allows for in-line identification of the influence of changed process parameters on the to-be-built part.

The featured video shows a comparisson of the size of the melt pool for contour scans of two consecutively scanned layers.

Accordingly, the influence of changed laser processing parameters on the size of the melt pool may be identified.
The featured video is part of Aconity3D’s ongoing effort towards increasing process understanding in the field of Laser-Powder Bed Fustion (L-PBF) with the ultimate goal of qualifying AM of metals for series applications
Inline process monitoring is available for all Aconity systems. Try our online machine configurator to configure your individual system now:
