Bioprinting parameters; such as pressure; nozzle size; and speed; highly influence the quality of the bioprinted construct. Moreover; cell suspension density and other critical biological parameters directly impact the biological function. Therefore; an approximation model that can be used to find the optimal bioprinting parameter settings for bioprinted constructs is highly desirable. Here; we propose a type-2 fuzzy model to handle the uncertainty and imprecision in the approximation model. Specifically; we focus on the biological parameters; such as the culture period; that can be used to maximize the output value (mineralization volume 21.8 mm3 with the same culture period of 21 days). We have also implemented a type-1 fuzzy model and compared the results with the proposed type-2 fuzzy model using two levels of uncertainty. We hypothesize that the type-2 fuzzy model may be preferred in biological systems due to the inherent vagueness and imprecision of the input data. Our numerical results confirm this hypothesis. More specifically; the type-2 fuzzy model with a high uncertainty boundary (30%) is superior to type-1 and type-2 fuzzy systems with low uncertainty boundaries in the overall output approximation error for bone bioprinting inputs.},
