Understanding 3D Printed Concrete and Its Applications Concrete for 3D printing is a specialized material influenced by its rheological properties. IIT Madras established the Imprint Lab, collaborating with Tasta, a leading Indian company in concrete 3D printing that evolved from manufacturing plastics to construction applications. This technology allows for complex shapes without traditional formwork, enhancing design flexibility.
Additive vs Subtractive Manufacturing: A Paradigm Shift Unlike subtractive manufacturing which involves cutting materials down to size, additive manufacturing builds objects layer by layer from digital models. This method minimizes waste and digitizes processes in construction akin to factory production methods. The goal is increased productivity through techniques like pre-cast concreting or on-site fabrication using advanced machinery.
Techniques of Concrete Printing: Extrusion and Beyond The primary technique used in concrete 3D printing is material extrusion; however, other methods such as binder jetting are also explored but suited for smaller components due to their intricacy requirements. Various machine types can execute these prints either onsite or offsite depending on project needs while different mixes including geopolymer can be utilized during the process.
From CAD Models to Final Products: The Printing Process Explained 'Creating a model via CAD software initiates the journey towards physical products through slicing into layers suitable for printers.' Conversion tools available online facilitate this transition from three-dimensional designs into executable formats like STL files before actual printing begins with careful attention given post-processing steps essential for curing and finishing concrete structures effectively.
