The AconityMIDI+ represents Aconity3D‘s newest machine concept for efficient industrial L-PBF application. The exchangable process chamber allows for parallelized setup times yielding decreased part costs. For maximum material flexibility and quality assurance, high temperature preheating of up to 1000 °C and Aconity3D‘s all new process monitoring system are available. The AconityMIDI+ is also available with up to 4 Lasers in the QUATTRO-Laser configuration, further increasing productivity.

As for all Aconity systems, the AconityMIDI+ is equipped with the web-based control software AconitySTUDIO, allowing for remote access to all relevant process parameters and machine components.

The AconityMIDI+ is available with a revolutionary Multi-Material powder depositioning system, allowing for manufacturing of Dual-Metal parts.


The AconityMIDI+ is Aconity's newest machine generation, suited for all production applications.

The first multi-material copper/steel part is printed by means of L-PBF on an AconityMIDI+. For that purpose the system is equipped with the optional all-new powder depostion system from Aerosint. The processed material combination was stainless steel (1.4404) and a copper alloy (CuCrZr). More materials will follow shortly.
