University of Turku Adds LPBF Platform for Three Powders in One Layer
The University of Turku has integrated a Schaeffler Aerosint SPD2.1-B5 recoater with an Aconity MIDI+, enabling research with up to three powders selectively deposited within one layer.
The University of Turku in Finland has integrated a Schaeffler Aerosint SPD2.1-B5 recoater into its existing Aconity MIDI+ laser powder bed fusion system. Three independent powder-delivery drums can place different powders in selected regions of the same layer before laser processing.
The installation is an experimental platform for co-designing component geometry and material placement, and for studying laser–material interactions, melting and solidification, interfacial bonding, and cracking. The University-led AM4Plasma project will investigate plasma-generator components that combine heat-resistant and heat-conducting regions, with possible relevance to fusion energy and aerospace propulsion.
This is a research-infrastructure announcement based on a University of Turku press release, not evidence that a three-material production component has been qualified or entered volume manufacturing. The University notes that reliable parts still require suitable material combinations, processing conditions, and interface quality.
Key facts
- A Schaeffler Aerosint SPD2.1-B5 was integrated with an Aconity MIDI+
- Three powder-delivery drums selectively place different powders within one layer
- The platform supports the AM4Plasma research project
- Research will cover interfaces, cracking, melting, and solidification
Context
Treating material placement as a design variable alongside geometry enables research into single components that combine thermal, structural, and wear functions.
