Direct ink writing of high-resolution cellulose structures

Three-dimensional (3D) printing has a significant role in membrane production for water purification and bio-separation, with capacity to create new and cleverly designed structures. Among the available 3D printing methods, the strategy of direct ink writing offers a process to print a wide variety of materials with high resolution. In a new report now published on Scientific Reports, Farnaz Rezaei and a team of researchers at the Uppsala University Sweden, used cellulose acetate as a biocompatible ink material. The researchers noted the printability and possibility of printing features as small as a few micrometers to examine the development of cellulose acetate with varying molecular weights. The nozzle's internal and external diameters affected the detailed resolution of the printed structure. The researchers used different inks to result in different widths of printed strands and successfully completed direct writing with high-resolution cellulose structures.
