Direct Ink Writing of Geopolymer Composites Reinforced With Polypropylene Fibers
Polypropylene fiber (PPf) reinforced geopolymer inks were systematically optimized for extrusion‐based additive manufacturing through regulation of ink composition, rheological parameters, nozzle size, and fiber content. The effects of polyethylene glycol (PEG) content and H2O to K2O ratio on printability were investig...
