The Particle Processing Group at the Institute of Interfaces and Particle Technology (IPT), FAU, was founded in 2011 as an additive manufacturing (AM) research unit. It focuses on developing scalable processes for producing and functionalizing feedstock powders for AM technologies such as selective laser sintering and melting, alongside methods for feedstock characterization. The group investigates process–structure–property relationships across the AM value chain to design tailored particle systems, working closely with academic and industrial partners. Recently, its research expanded to include particle systems for printing and coatings, emulsion-based drug delivery, nanoparticle hetero-aggregates for catalysis and energy, soft-matter comminution, recycling, and sustainable materials, structured around four main research pillars.
