Her work focuses on the mechanical and microstructural effects of modifying the crystallographic orientation while simultaneously reducing the volume of components in additive manufacturing. We had the opportunity to speak with her about her research, her experiences, and the insights she gained during her stay.

A Passion for Manufacturing

Maialen’s academic journey began with a thesis in the field of subtractive manufacturing. However, as additive manufacturing gained momentum, she recognized its growing importance. In Spain, she is closely connected to the CFAA, an advanced manufacturing center for the aerospace industry, which focuses on developing lightweight components. Her goal is to become a professor, and pursuing a PhD at UPV—where she also earned her bachelor's and master’s degrees—offers her valuable opportunities for research and industry collaboration.

International Collaboration and New Insights

A key aspect of Maialen’s stay was the opportunity to work in an international environment. She appreciated seeing how researchers in Germany approach similar challenges, gain new insights, and work with various machines. What impressed her most was the collaborative working style at PTW. She noted that although there are separate teams for additive and subtractive manufacturing, everyone is willing to support each other.

“The working environment here is fantastic. There are more PhD students than at my home institution, which creates a supportive atmosphere. We all understand the challenges of doing a PhD, and this mutual understanding makes a big difference.”

Cultural and Scientific Differences

While her hometown Vitoria and Darmstadt share similarities as walkable cities, Maialen also noticed cultural differences—like the earlier lunchtime hours in Germany. Nevertheless, she adapted quickly. One of her biggest surprises was how welcoming and supportive her colleagues were.

“I didn’t expect to feel so comfortable here. Germans are much warmer than I thought. Maybe it’s the city or the university, but I feel very safe and integrated.”

Her initial concern about the language barrier turned out to be unfounded. Although she had taken some German lessons before her arrival, she found that everyone at the institute speaks fluent English, which made the transition easier.

Challenges and Future Prospects

Despite the short duration of her stay – only three months – Maialen made significant progress in her research. She used the EOS M290 Additive Manufacturing Machine to print her components. Some colleagues supported her in using the Zeiss coordinate measuring machine and milling the samples on the GROB G350 machining center to analyze cutting forces and vibrations during the subtractive process. She wishes she had more time to complete her current project but plans to continue the collaboration remotely.

Looking ahead, she is excited to further analyze her results. She found the surface quality of the printed parts particularly noteworthy, as it provided unexpected insights. Maialen is convinced that developments in additive manufacturing will continue to advance rapidly, and she is eager to contribute to this progress.

Advice for Young Researchers

For young researchers considering an international experience, Maialen has a clear message: “Do it!” In her opinion, international research stays offer valuable opportunities, even if they come with challenges. Those who take on the experience grow not only professionally, but also personally. She also encourages researchers to attend conferences and take every opportunity to expand their professional network.

Personal Impressions and Future Plans

In addition to her professional development, Maialen also cherished her personal experiences in Darmstadt. Whether running, bouldering, or enjoying dinners and beers with new friends, she created lasting memories.

A particularly impactful moment for her was a software issue she faced early in her stay. When she felt stuck, her supervisor left a small note on her computer that read: “Never lose faith.” A small gesture with a big impact—it reminded her to keep going.

When asked about her dream research destination, Maialen mentions MIT or a university in China as exciting options – due to their innovative research and unique cultural aspects. Nevertheless, she hopes to return to Darmstadt one day – not only for research, but also to reconnect with the people she met here.
