“…Bioprinting is an emerging technology that integrates robotic dispenser with multi-materials and living materials. It has brought many benefits to tissue engineering and other biomedical applications by fabricating customized tissue constructs and prostheses [ 1 , 2 , 3 ]. A typical bioprinting system consists of three components including: (i) living materials which mostly refer to cells; (ii) hydrogel or bioink; and (iii) a bioprinter [ 4 , 5 ].…”

A Mathematical Model on the Resolution of Extrusion Bioprinting for the Development of New Bioinks

et al. 2016

Pneumatic extrusion-based bioprinting is a recent and interesting technology that is very useful for biomedical applications. However, many process parameters in the bioprinter need to be fully understood in order to print at an adequate resolution. In this paper, a simple yet accurate mathematical model to predict the printed width of a continuous hydrogel line is proposed, in which the resolution is expressed as a function of nozzle size, pressure, and printing speed. A thermo-responsive hydrogel, pluronic F127, is used to validate the model predictions. This model could provide a platform for future correlation studies on pneumatic extrusion-based bioprinting as well as for developing new bioink formulations.

Purpose -The purpose of this paper is to describe a novel design workflow for the digital fabrication of custom-made orthoses (CMIO). It is intended to provide an easier process for clinical practitioners and orthotic technicians alike. It further functions to reduce the dependency of the operators' abilities and skills. Originality -Although some research has been developed on digital fabrication of CMIO, few studies have investigated the use of desktop 3D Printing in any systematic way. This study provides a first step in the exploration of a new design workflow using lowcost digital fabrication tools combined with non-manual finishing. Social implications -The feasibility of the process increases the impact of the study, as the great accessibility to this type of 3D printers makes the digital fabrication method be easier to be adopted by operators. Methodology -The technical assessment covers low-cost 3D scanning, free CAD software, and desktop 3D Printing and acetone vapour finishing. To analyse its viability, a cost comparison was carried out between the proposed workflow and the traditional CMIO manufacture method. Findings -The results show that the proposed workflow is a technically feasible and cost effective solution to improve upon the traditional process of design and manufacture of custom-made static TMC orthoses. Further studies are needed in order to become a clinically feasible approach and to estimate the efficacy of the method for the recovery process in patients.

El alginato es un biopolímero no tóxico, biodegradable, biocompatible, soluble en agua y renovable, extraído habitualmente de algas pardas o producido mediante cultivo microbiano. Este biomaterial está aprobado por la Food and Drug Administration (FDA) de Estados Unidos para su uso en humanos en ciertas aplicaciones biomédicas. Además, existe una amplia gama de tipos de alginato diseñados con propiedades diversas según la aplicación específica. En el presente trabajo de revisión se pretende mostrar las inmensas aplicaciones que ofrece este biopolímero y que siguen en crecimiento exponencial debido a sus excelentes propiedades químicas, físicas y biológicas. De este modo, se presentan aplicaciones actuales en áreas importantes como la industria farmacéutica, la industria química y textil, la industria gastronómica y de la congelación, la inmovilización biotecnológica de células y enzimas, la liberación controlada de biomoléculas, la industria biomédica y finalmente el análisis de su creciente uso en la bioimpresión 3D.
