AMAZEMET partners faced challenges in the Sunflower project under the Clean Energy Transition Partnership – CETP call. The project aims to develop novel solar energy receivers for Concentrated Solar Power (CSP) plants that could be both more efficient (from ~20% to ~40%) and manufactured more sustainably. The project investigates 2 paths to reach its goals regarding Energy absorbed - SiC, a ceramic material, and FeCrAlY heat-resisting group of alloys as candidates to fulfill the project's goals.

Additive Manufacturing is a process of creating objects by adding material layer by layer, in contrast to traditional subtractive methods that remove material from a solid block. Metal Additive Manufacturing specifically involves the use of hard-to-machine metals to produce parts and components using bottom-up approach. This method allows for greater design flexibility, material efficiency, and the production of complex geometries that would be impossible or extremely difficult with conventional manufacturing techniques.

Developing new alloys specifically tailored for additive manufacturing (AM) is crucial to unlocking the full potential of this innovative manufacturing technique. While legacy alloys, developed primarily for traditional manufacturing processes such as casting or forging, can be used in additive manufacturing, they may not fully leverage the unique capabilities and process conditions inherent to AM. Read the article to find out, why the development of new alloys is so important for additive manufacturing!

Bioresorbable materials for additive manufacturing represent an innovative area in materials science and engineering combined with biomedical engineering for novel treatment routes of patients. Bioresorbable metals are designed to degrade safely within the body over time, eventually being absorbed without causing harm or toxicity. When used in additive manufacturing these metals can be shaped into complex, patient-specific implant with precision.

It can be seen that alloying had taken place during atomization, with Al, Cr and Ru distributed relatively homogenously within the Pt-based powder particles. The powders were spherical with a low number of fine satellite particles. This work shows that with use of AMAZEMET rePowder it is clearly possible to produce spherical metal powders for additive manufacturing from compacted elemental powders with even as low as ten grams of feedstock.

High entropy alloys are hard to obtain due to often usage of refractory elements. Thanks to the fact that arcMELTER can be equipped with focus plasma torch working with such elements is much smoother than just standard TIG torch.
