Dr. Inka Dressler Pioneers 3D Printing in Construction
Dr. Inka Dressler, a researcher at TU Braunschweig, is at the forefront of innovative manufacturing processes. Her focus is on the 3D printer particle bed printing method, aiming to create precise and efficient production of complex structures. Meanwhile, 3D-printed houses have become a reality in Germany, with prototypes for single-family and multi-family homes.
Dr. Dressler's research involves exploring the material-process interaction of 3D printer particle bed printing. She studied this during a research stay in Brittany, concentrating on liquid penetration and distribution. The process involves applying a sand-cement mixture in layers and activating it with a liquid to form a three-dimensional structure. The goal is to achieve concrete strength comparable to normal concrete, currently around 20 megapascals.
In parallel, researchers at TU Braunschweig and TU Munich are collaborating in the SFB/TRR277 collaborative research center. They are investigating materials and printing methods for 3D construction. Dr. Dressler is involved in two projects within this center, focusing on 3D printer particle bed printing and reinforced shotcrete elements. Her work aims to develop a formula describing how particle size affects liquid penetration depth, ensuring geometrically precise and mechanically robust components. The 3D printer particle bed printing process offers flexibility in geometry choice and design, currently used in furniture and facade elements.
Dr. Inka Dressler's research is pivotal in advancing the field of 3D printing, particularly in construction. Her work, along with other researchers, is paving the way for more sustainable and efficient building methods. The potential of 3D-printed houses is now a reality, and further innovations are expected to shape the future of construction.
