🚀 Just a quick throwback to my Masterthesis at EDEK · University of Kassel under supervision of Philipp Alexander Eversmann and Benedikt Wannemacher : Additive Robotic Manufacturing Of Reusable Sand Molds For Complex Geometries Out Of Concrete In this project, I explored a novel approach to creating reusable sand molds for complex concrete geometries using robotic additive manufacturing. The traditional methods of concrete formwork are not only labor- and material-intensive but also generate significant waste especially if the geometrz is a little complex our has curves. My goal was to align with the Triple Zero® design principles—Zero Fossil-Based Energy, Zero Waste, Zero Emission—by employing fully recyclable materials and advanced tech. Over the course of a single semester thesis, I developed the first prototype. The project aimed to combine the versatility of waste blacksand from metal industry and water (which was the only binder) with the precision of robotic printing to create complex, reusable molds for concrete casting. This initial prototype serves as a proof of concept to investigate the potential of this approach. Watch the video below to see the prototype and get a glimpse of the potetial if this Idea. #3DPrinting #3DPC #Robotics #Smoothing #ResearchAndDevelopment #Innovation #SurfaceQuality #RoboticFabrication #AdditiveManufacturing #PathPlanning #StructuralEngineering #ConcreteTechnology #ABB #Algorithm #Rhino3d #Grasshopper3d #Automation #Precast #Industrie40 #3DDruck #3drcp #SandPrinting #ParametricDesign #PrefabricatedConcrete #Automation #ConstructionInnovation #3DModeling #ResearchAndDevelopment #E2E #automation #ComputationalDesign #Prototyping #Concrete #Innovation #ConstructionTech #WorkflowOptimization #3DPrinting #ParametricDesign #EngineeringExcellence

Had a great time presenting my research at the American Ceramics Society (ACerS) Cements Division (in a concrete 3D printing lab). I appreciated the friendliness of the cements community, stimulating research conversations on my work, and meeting many other researchers studying the materials science of cements. Concrete is the most used material on the earth after water. Concrete is a complex and dynamic material system that gets further complicated with new mix designs, admixtures, chemistries, and processing techniques (like 3D printing). Further, global infrastructure development and the ongoing climate crisis is pushing the cement industry to find ways to uphold society's building needs while mitigating negative effects on the planet. Materials scientists who understand small-scale interactions leading to large-scale performance, and who have a passion for sustainability, can help research new solutions for this age old and ubiquitous material.

"In the main hall of the research and robotics Arch Tec Lab on Hönggerberg campus, several robotic arms hang from the roof, while half-finished beige-colored curved structures reminiscent of sand sculptures are dotted around the floor. On one side of the room, mysterious parts protrude from wooden crates. Standing in front of one of these crates is Patrick Bedarf. He works in Professor Benjamin Dillenburger's Digital Building Technologies group and completed his doctorate at the end of September. As part of his doctoral thesis he studied how lightweight insulating construction elements—especially more complex shapes—could be manufactured to reduce materials." #3dprinting #insulationmaterials #materialscience #constructionmaterials

I came across an intriguing study on the mechanical properties of wood/PLA biocomposite filament in 3D printing, and I thought it was worth sharing. 🌱 The research focuses on blending PLA with wood powder to create a sustainable filament that's not only eco-friendly but also offers a natural look for 3D-printed parts! What really caught my eye was the use of machine learning to predict these mechanical properties. The researchers applied algorithms like XGBoost and AdaBoost, with XGBoost delivering exceptional accuracy (R² > 0.99) in predicting the properties based on the printing parameters. This study highlights the potential of combining sustainable materials with advanced technologies like machine learning to push the boundaries of additive manufacturing. A great read for anyone interested in 3D printing, materials science, or sustainable innovation! #3DPrinting #Sustainability #Innovation #AdditiveManufacturing #MachineLearning

#spotlight #on!💡   This is a new series of posts to bring the manifold #research of the whole #faculty into the spotlight and present what happens behind closed (lab) doors! Interested in being featured with your own project? Get in touch with Miriam Böhm! We will start this series with Dr. Elodie Donval, who is a postdoc in the working group of Prof. Matti Schneider - Engineering Mathematics, Civil Engineering:   “My current research project focuses on the mechanical properties of #3D #printed sand cores for #casting. This innovative process addresses two #challenges: the use of inorganic binders that are more environmentally friendly, and the generation of complex shapes through 3D printing. However, the behaviour of the printed material is not so well understood. My role in this project: to model the microstructure (i.e. how the grains are assembled) and provide insights into how it relates to the macroscopic mechanical properties.”   Want to learn more about Elodies work?

Pleased to see that another piece of research from my PhD has been accepted for publication, this time in Chemical Engineering and Processing - Process Intensification! Using OpenFOAM simulations, we looked closely at the relative contributions of fluid- and solid-phase heat transfer in 3D printed catalyst structures and correlated their performance to the operating conditions. The paper also contains some reactive studies, which are very heavy simulations. However, we could get a decent estimate of the reactive performance using a phenomenological model with the developed heat transfer correlations. This demonstrates the applicability of the correlations and presents some perspective on simulation scale-up. Many of these results are based on the fantastic work that Mattia Galanti did in his MSc. graduation project. Also thanks to Martin van Sint Annaland and Ivo Roghair for the continued supervision.

That's a wrap for the (2nd Annual) 2024 #SmartMTX in Red Deer! I didn't think it would be possible to beat the first one, but this one was even better. The connections made were of the highest caliber. 3DSpaceTerraform was invited to present our "alternative materials in construction and 3D printing" research and technology development display to Premier Danielle Smith, as part of her Expo Tour. It goes without saying that we are pretty excited about using local agricultural and earthen materials in engineered product development, and we daresay the Alberta Premier was intrigued and excited as well. Alberta is an incredible place for natural resources. From hemp fiber to local minerals for binders, we literally "have it going on." Our ability to develop technology and products is unmatched; we have the land, the resources, and the people who truly care. It isn't talked about in the news as much, but our holistic food movement, alternative building movement, and permaculture-focused living movement are rich and matured and very active. What's next? Well, we made additional connections at the show, particularly around funding for the next stages of technology development for hempcrete 3D printing (insulative extrusion development) - part of what we need for Canadian-appropriate 3D printed construction. It's time to scale up and apply our long experience in alternative conventional construction with the potential of 3D printed construction. Thanks Manufacturing & Export Enhancement (MEE) Cluster for another excellent SmartMTX. #3DEP #construction3dprinting #alternativematerials #CANBE #engineeredresilience #carboneconomy #alberta #3DCP #regionallyappropriate #3DST #3dspaceterraform
