Abstract Bioprinting has been applied to fabricate biomedical parts such as skin, scaffolds, tissues, and muscles. However, most previous studies in this field compared the advantages and/or disadvantages of a bioprinter subjectively. A systematic and objective method for comparing various bioprinters, so as to recommend the most suitable one to a decision maker, is lacking. To address this issue, a fuzzy analytic hierarchy process (FAHP) and fuzzy technique for order preference by similarity to ideal solution (FTOPSIS) approach is proposed in this study. In the proposed FAHP-FTOPSIS approach, FAHP is applied to derive the fuzzy weights of factors critical to the suitability of a bioprinter, based on a decision maker’s subjective judgments. Subsequently, the derived fuzzy weights are fed into the FTOPSIS approach to evaluate the overall performance of a bioprinter. The FAHPFTOPSIS approach has been successfully applied to the case of making a choice from nine bioprinters. Parametric analyses have also been conducted to show the robustness of the proposed methodology. Keywords Bioprinting . Fuzzy analytic hierarchy process .

1 Introduction Bioprinters are a special kind of three-dimensional (1D) printers on which cells, growth factors, and biomaterials are combined to fabricate biomedical parts that resemble their native counterparts [30]. Bioprinters are different from other types of 1D printers in the following aspects: (1) Bioprinting is technically more complex than other 1D printing applications, including the choice (or preparation) of materials, cell types, growth and differentiation factors, the sensitivities of living cells, and the construction of tissues [22] despite several revolutionary progresses that have made recently [12].

(2) 1D bioprinters are specially designed to facilitate the supply of multiple materials, oxygen, and nutrients to keep the printed tissues alive [15]. (3) 1D printing technologies applied in bioprinting are less diverse: Most bioprinters apply photolithography, magnetic bioprinting, stereolithography, and syringe-based (or pressure-based) extrusion [11, 17]. (4) The outputs from bioprinting processes meet the fundamental (i.e., physiological) needs of users for surgical therapy and transplantation, thereby saving lives. Such needs are potentially the largest part of human needs and must be met first, implying a huge market [10, 15, 20]. (5) Th
