{"title":"What If Materials Could Think Ahead?","authors":"Anna Rosa Ziefuss,&nbsp;Stephan Barcikowski,&nbsp;Gerrit Albert Luinstra","doi":"10.1002/adem.202501628","DOIUrl":"https://doi.org/10.1002/adem.202501628","url":null,"abstract":"&lt;p&gt;Additive manufacturing (AM) has revolutionized how we shape matter, but perhaps more profoundly, how we must now think about materials. Traditionally, materials were designed to be shaped—cast, rolled, and extruded—and their properties fixed well before the part existed. In AM, this logic is no longer valid: matter is deposited, fused, or cured layer by layer, and properties emerge during the process. Microstructures become spatially heterogeneous; functionality evolves as a design parameter. This shift turns the old paradigm on its head. The goal is no longer to select materials that can tolerate the stresses of AM; the new challenge is to design materials that actively enable it. To fully exploit AM's potential, from lightweight, load-adaptive structures to multimaterial integration (heat-resistant), materials must become co-designers of the process.&lt;/p&gt;&lt;p&gt;This mindset sparked the German Priority Program SPP 2122 “Materials for Additive Manufacturing,” funded by the DFG (uni-due.de/matframe/). Launched in 2018, the program brought together researchers from powder metallurgy, polymer chemistry, materials modeling, and process engineering. Their shared goal is to establish a material-centric foundation for AM, spanning metal and polymer powder devalopment, theory and experiment, nanoscale control, and industrial relevance.&lt;/p&gt;&lt;p&gt;To build on this vision, the SPP 2122 began with a systematic state-of-the-art analysis of AM from a materials perspective. Two comprehensive reviews—one on metal-based&lt;sup&gt;[&lt;/sup&gt;&lt;span&gt;&lt;sup&gt;1&lt;/sup&gt;&lt;/span&gt;&lt;sup&gt;]&lt;/sup&gt; and one on polymer-based&lt;sup&gt;[&lt;/sup&gt;&lt;span&gt;&lt;sup&gt;2&lt;/sup&gt;&lt;/span&gt;&lt;sup&gt;]&lt;/sup&gt; feedstocks—mapped out the scientific landscape of laser powder bed fusion (L-PBF) over the past decade. The reviews identified the dominant materials (e.g., AlSi10Mg, PA12), prevailing process parameters, and emerging strategies such as nanoparticle additivation to overcome issues like anisotropy, cracking, or poor mechanical performance. By extracting and statistically analyzing material, process, and part properties across hundreds of studies, both works revealed that the future of L-PBF hinges on an integrated understanding of powder design, process control, and functional performance.&lt;/p&gt;&lt;p&gt;Complementing these reviews, a dedicated white paper laid the groundwork for a large-scale interlaboratory study (ILS) on powder bed fusion using a laser beam (PBF-LB) of metals and polymers.&lt;sup&gt;[&lt;/sup&gt;&lt;span&gt;&lt;sup&gt;3&lt;/sup&gt;&lt;/span&gt;&lt;sup&gt;]&lt;/sup&gt; It highlighted the urgent need for standardized test methods and reliable metrics to assess nanoadditivated powders across the entire process chain. The white paper emphasized how nanoparticles affect not only flowability and absorption but also microstructure formation and mechanical properties, and proposed a data-rich framework based on the findable, accessible, interoperable, and reusable (FAIR)-principles and principal component analysis to reveal hidden correlations across the material-process-part c","PeriodicalId":7275,"journal":{"name":"Advanced Engineering Materials","volume":"27 14","pages":""},"PeriodicalIF":3.4,"publicationDate":"2025-07-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/adem.202501628","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144681238","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Their role extends further into microfluidics, enabling precise manipulation of droplets in lab-on-a-chip devices and into stimuli-responsive materials, where controlled wetting behavior dictates adaptive and functional performance.&lt;/p&gt;&lt;p&gt;A cornerstone in our understanding of wetting behavior was Young's equation (1805), which established the balance of interface forces at the three-phase contact line, defining the equilibrium contact angle of a liquid droplet on a solid substrate. Followed by the pioneering studies by Wenzel (1936) and Cassie–Baxter (1944), which further refined this knowledge by introducing wetting models that explain how surface roughness and chemistry influence liquid behavior. The Wenzel model describes liquid infiltration into textured surfaces, leading to strong adhesion, while the Cassie–Baxter model highlights the formation of air pockets on structured surfaces, resulting in extreme water repellency. These principles laid the groundwork for modern surface engineering, guiding the development of superhydrophobic coatings, icephobic materials, and adaptive wetting surfaces. Building upon these fundamentals and drawing inspiration from nature, including the hierarchical microstructures of lotus leaves, the rose petal effect, and hydrophobic adaptations in animal fur and insect legs, scientists have engineered precise wettability control to create surfaces with remarkable water management properties. These innovations have unlocked new functionalities, including self-cleaning coatings, enhanced water repellency, and responsive wetting control, with materials ranging from superhydrophobic and oleophobic surfaces to slippery liquid-infused porous films (SLIPS) and amphiphilic coatings.&lt;/p&gt;&lt;p&gt;The control of liquid–surface interactions has been critical in the design of icephobic surfaces, where the behavior of water droplets before freezing determines ice nucleation, adhesion, and removal mechanisms. Ice accretion presents a severe challenge, affecting not only daily life but also critical industrial applications. Frozen power lines, traffic signals, and transportation systems suffer from efficiency losses and increased maintenance demands, while wind turbines, solar panels, and aeronautical surfaces face performance degradation and safety risks.&lt;/p&gt;&lt;p&gt;Developing next-generation icephobic solutions requires interdisciplinary advancements in surface engineering, ice adhesion reduction, and mechanical durability, ensuring optimal performance under extreme environmental conditions.
