AconityTWO is the latest high-tech production system developed by Aconity3D. It is designed for use in the production of larger industrial parts with a large-format building platform of Ø 400 mm. The Easy-Access machine cover enables quick material change with simultaneous access to all important technical components.

As with all Aconity systems, the AconityTWO offers access to all relevant process parameters and can be modularly equipped with a preheating device, process monitoring, or a modified laser configuration for maximum customer benefit.

The fully automated powder refilling system in combination with Aconity’s own sieving station AconitySIEVE further increases productivity at maximum operator safety. The passivation of the filter ensure fluent 3D printing and decreases the operational expenses.

The AconityTWO is also available as a FOUR-Laser system for further maximized productivity. At this, the AconityTWO allows for a full overlap of all laser sources onto the complete build area of 400 mm at variable laser spot sizes of 80 – 500 µm. In addition, the multi-laser configuration can be configured for master-slave operation for targeted preheating and postheating of local component areas during the build. This is enabled by Aconity’s own developed 3D scan head technology.
