Methods, systems, and devices for extrusion-based three-dimensional printing are provided. The methods, systems, and devices allow for the printing materials such as fabrics, clothing, and wearable and/or implantable devices. A number of different enhancements are provided that allow for this improved form of three-dimensional printing, including: (1) printing using a polymer (e.g., cellulose acetate) dissolved in a solvent (e.g., acetone)； (2) selectively bonding portions of a deposited filament onto one or more surfaces and/or one or more previously deposited filaments； (3) using particular toolpaths to create a fabric or similar material by creating a woven pattern； and (4) printing across multiple layers even when previous layers are not complete. Other aspects of the present disclosure, including other enhancements and various printer configurations, are also provided.
