Dimensionics Density: Innovations in Automated Density Determination for 3D Printing

At Formnext 2023, Dimensionics Density has attracted great interest with its innovative technology for automated density determination. This development underlines the trend in additive manufacturing (AM) towards cost-effective, reliable and automated technologies that are suitable for series production.

Philipp Pruesse, Head of Sales at Dimensionics Density says “To say we were overwhelmed by the interest we received from attendees at Formnext would be an understatement, and in the days since the show, we have been busy securing commercial engagement from companies across industry. We are convinced that the level of interest is because our automated density determination technology exists at the sweet spot of demand in the AM ecosystem, where validation and automation are critical. Validation in AM is crucial when the technology is used for production because it ensures the reliability and quality of 3D printed parts, especially in industries where safety and precision are paramount, like aerospace and healthcare. Automated solutions in the AM ecosystem are essential because they enhance efficiency, reduce human error, and enable scalability, allowing for faster and more consistent production of complex parts at volume.”

Dimensionics Density’s density determination technology perfects the classic Archimedes’ principle by integrating advanced automation technology. The process is precisely designed: Samples are placed in specially designed carriers that are accurately positioned on vibration-isolated scales by a robotic arm. A special lifting frame lifts the sample out of the carrier for the weighing process. This automation eliminates human error and ensures consistent placement.

The system is also equipped with climate sensors that monitor temperature, air pressure and water temperature. This data is fed into a sophisticated evaluation algorithm that corrects each density measurement taking into account the ambient conditions.

Pruesse concludes, “Our density determination technology has already been adopted by among other companies FKM (Germany’s largest full-service powder bed fusion 3D printing bureau), and has been independently reviewed by Fraunhofer IAPT and recognised as a good fit for applications where a statement on the density has to be made quickly or frequently, therefore making it appropriate for volume production scenarios. The engagements that we made at this year’s Formnext event will ensure that we continue to support companies looking to optimise their quality control processes, giving confidence in outcomes, and therefore cementing the position of AM as a disruptive and agile production technology.”
