Additive Manufacturing Progress Update: Optimizing Parameters and Advancements in 3D Printing Technology
The latest edition of the engineering.com Additive Manufacturing Progress Update brings exciting developments in the world of 3D printing. From ribbed concrete ceilings to thermal analysis in laser powder bed fusion, researchers are pushing the boundaries of what is possible with additive manufacturing.
One notable study from RWTH Aachen University in Germany showcases the creation of modular ribbed concrete ceilings using a combination of 3D concrete printing and carbon fiber reinforced polymer grids. This innovative approach reduces material usage by 40-50% and automates the fabrication process, making these structures more practical for real-world projects.
Another study from Norwegian University of Science and Technology and University of Bristol delves into the effects of pre- and post-heating on carbon fiber reinforced polyamide 6 in 3D printing. By optimizing temperature variations, engineers can enhance the strength of additive components and achieve near isotropic, complex parts.
In the realm of laser powder bed fusion, researchers from the University of Applied Science Muenster and University of Siegen in Germany explore the impact of high scan speeds on the quality of stainless steel 316L parts. By fine-tuning scanning parameters, they achieve parts with high relative densities and improved surface finish.
Additionally, researchers at the Empa Swiss Federal Laboratories for Materials Science and Technology are leveraging machine learning to reduce the computational cost of simulating laser powder bed fusion. Their open machine learning model for thermal analysis offers a faster and more efficient way to predict temperature profiles in 3D printing processes.
On the business front, publicly traded additive manufacturing companies are facing challenges, with share prices down across the board. However, sustainability is a key focus in the industry, with organizations like ASTM International and the University of Waterloo investing in research on AM’s environmental benefits.
Overall, the latest developments in additive manufacturing are pushing the boundaries of what is possible with 3D printing technology. From innovative construction techniques to advanced thermal analysis, researchers and businesses are driving the industry forward towards a more sustainable and efficient future.
