title: DFG SPP2122 Interlaboratory Study Dataset

description: &lt;p&gt;An interlaboratory study (ILS) has been designed within the DFG Scientific Priority Program 2122 “Materials for Additive Manufacturing” (SPP 2122) for testing nanoparticle-modified and virgin AlSi10Mg and PA12 powder feedstocks along the entire process chain of powder bed fusion using a laser beam. The dataset contains measured powder, process, microstructure, and structural properties of both virgin and nano-modified metals and polymers generated by central laboratories and PBF-LB machines following the standard operational procedures (DOI: &lt;a href="https://doi.org/10.17185/duepublico/82630"&gt;10.17185/duepublico/82630&lt;/a&gt;)&lt;/p&gt;
&lt;b&gt;Methods&lt;/b&gt;
&lt;p&gt;A comprehensive interlaboratory study (ILS) conducted across 32 international research institutions, investigating six feedstock types (virgin and nanoparticle-modified metals and polymers) along the entire PBF-LB process chain. For this purpose, a total of 69 different powder features were evaluated for each of the six powder material variants, as well as 15 process characteristics per print job and 78 part features, which were executed centrally (characterization) and decentralized (processing) strictly following SOPs (DOI: &lt;a href="https://doi.org/10.17185/duepublico/82630"&gt;10.17185/duepublico/82630&lt;/a&gt;) including Research Data Management regulations. From these features, more than 1,200,000 data points were extracted for research data processing.&lt;/p&gt;
