3D printing has opened up a completely new range of possibilities, including for example production of turbine buckets. However, the 3D printing process often induces internal stress in these components which can in the worst case lead to cracks.
Sustainable industry and resource use
High-grade biopolymers can be obtained from wood, which could replace fossil resources as a base material for a variety of products. However, this requires gentler processes than, for example, the production of cellulose for paper manufacture. So-called ionic liquids are suitable for breaking down wood in a gentle first-treatment step, and for making its components accessible for further processing.
