Particle-Bed 3D Printing by Selective Cement Paste Intrusion (SPI) – Particle Surface Functionalisation, Particle Synthesis and Integration of WAAM Reinforcement

Selective paste intrusion (SPI) is a particle-bed-based additive manufacturing technology in which aggregates are spread in thin layers and bonded by cement paste. To qualify SPI for structural concrete elements, the inclusion of reinforcement is mandatory. The innovation introduced here is that reinforcement will be implemented simultaneously in the SPI process using Wire and Arc Additive Manufacturing (WAAM). Different active and passive cooling strategies, e.g. particle surface functionalization and the synthesis of new particles, will be developed to deal with the high temperatures during WAAM.

Objective

Combination of SPI and WAAM:

  • 3D printable WAAM reinforcement with properties comparable to those of conventional rebars, validated through experiments and simulation
  • Development of tailored particles for cooling and storing water for the combined SPI+WAAM process
  • Optimized cement paste for enhanced temperatures

Approach

At the cbm, the Selective Paste Intrusion (SPI) is being researched. One research focus is the integration of reinforcement using Wire and Arc Additive Manufacturing (WAAM) during the printing process. Due to the temperature loads of the WAAM process, the system limits, such as the maximum temperature load in the SPI process, must first be quantified. From this, process parameters and strategies to reduce the temperatures are derived and also researched. Approaches here are the functionalization of the aggregates and optimization of the cement paste formulation to withstand higher temperatures. However, an increase in the distance between the particle-bed and the printer nozzles and active cooling of the WAAM process are strategies for reducing the temperature load. The aim is to combine the two individual processes, SPI and WAAM, into one process and produce a demonstrator.

The Institute for Particle Technology is conducting a closer inspection into developing tailored particles suitable for the hybrid process. On the one hand, an optimal combination of particle size distribution and morphology of the aggregate particles as well as cement paste are to be found to support the process. On the other hand, the effect of certain additives on both components are being studied to reduce or withstand the remaining thermal load. One approach involves integrating additional water into the aggregate bulk material and cement paste whilst maintaining sufficient material properties for SPI. Further studies will involve combining the aforementioned with binding accelerators to increase process speed.

At the iwb, suitable process parameters for the production of WAAM-manufactured reinforcement structures are identified and process investigations are conducted with an experimental setup. Thereby, the cooling behaviour of the manufactured reinforcement geometries is analysed using thermographic imaging. Based on this, the cause-effect relationships in WAAM of the steel reinforcement are quantified by regression analyses. Numerical process models are created to extend the understanding of the process. These models describe the temperature distribution in the WAAM-manufactured component and consider the influences of specifically cooled areas. Thus, a suitable cooling strategy can be derived theoretically and be validated, after integration into the experimental set-up.

Laser Powder-Bed Fusion (LPBF) of Steel Elements for Construction – Basics of Design and Mechanical Resilience.

This project aims to explore and evaluate the factors influencing the manufacturing of safe and durable structural steel elements by Powder Bed Fusion of Metals using a Laser Beam (PBF-LB/M). Thereby, the PBF-LB/M process, the post-treatment, and the geometrical aspects in terms of microstructure and mechanical properties will be investigated and correlations determined. In the first funding period, it is focused on analyzing small-scale specimens and complex facade elements with multiaxial stress states. Based on the results, a first methodology for a qualified Additive Manufacturing (AM) design of safe and durable structural steel elements will be derived.

Objective

Until now, a precise prediction of defined mechanical properties of PBF-LB/M-manufactured steel elements is not possible. To establish the application of PBF-LB/M in the construction industry, civil engineering, and architecture, it is necessary to develop a methodology for the reliable production of durable structural steel elements by using PBF-LB/M.

Approach

Initially, the influence of the process parameters on the cooling rates during PBF-LB/M is analyzed using in-process thermography. Besides, the effects of geometric aspects and post-treatments on the mechanical and metallurgical properties of the components will be examined. In the further course of the project, shape-optimized structural steel elements and large-scale components will be designed using the determined interrelations. Subsequently, the elements will be manufactured and tested under real operating conditions. Finally, a methodology for the economic and process-safe use of PBF-LB/M in the construction industry will be derived.
