Abstract:
In recent years, bioprinting has emerged as a promising technology for the construction of three-dimensional (3D) tissues to be used in regenerative medicine or in vitro screening applications. In the present study, we present the development of an inkjet-based bioprinting system to arrange multiple cells and materials precisely into structurally organized constructs. A novel inkjet printhead has been specially designed for live cell ejection. Droplet formation is powered by piezoelectric membrane vibrations coupled with mixing movements to prevent cell sedimentation at the nozzle. Stable drop

Abstract:
Three-dimensional bioprinting has emerged as one of the manufacturing approaches that could potentially fabricate vascularized channels, which is helpful to culture tissues in vitro. In this paper, we report a novel approach to fabricate 3D perfusable channels by using the combination of extrusion and inkjet techniques in an integrated manufacture process. To achieve this, firstly we investigate the theoretical model to analyze influencing factors of structural dimensions of the printed parts like the printing speed, pressure, dispensing time, and voltage. In the experiment, photocurable hydro

Abstract:
 With high precision, drop-on-demand, and noncontact material delivery advantages, inkjet bioprinting technology has been widely used in tissue manufacturing. However, the main challenge of inkjet bioprinting is that the bioink must be liquid-like in the printhead to avoid clogging the nozzle, then form microdroplets, and finally undergo crosslinking to quickly form a gel and make an object with strength and precision. The primary solution relies on the fast crosslinking of sodium alginate by calcium chloride. Nevertheless, it is difficult to guarantee the precision of inkjet bioprint

Abstract:
Although inkjet-based bioprinting enables precise drop-on-demand cell deposition within three-dimensional (3D) tissue constructs and facilitates critical cell–cell and cell–matrix interactions, it faces challenges such as poor cell homogeneity and low cell viability. To date, there is a lack of comprehensive review papers addressing the optimization of cell deposition in inkjet-based bioprinting. This review aims to fill that gap by providing an overview of various critical aspects in bioprinting, ranging from bio-ink properties to the impact of printed droplets. The bio-in

Abstract:
Digital inkjet printing has been developed as a pivotal technology for precise, scalable, and cost-effective deposition of functional inks, enabling significant advancements in flexible printed electronics and bioprinting applications. Analysis of Deborah number (De), defined as the ratio between relaxation time and capillary time, serves as a critical parameter for linking between ink rheology and inkjet printability. However, determining the relaxation time of polymer-containing weakly viscoelastic fluids remains challenging due to the need for high-frequency measurements of storage and loss

Abstract:
In the field of additive manufacturing, laser or electron beam based 3D printing is widely investigated for biomedical applications. However, much less explored is the binderjet 3D printing, which allows processing of biomaterials at physiologically relevant conditions. In this context, this thesis presents a set of experimental and theoretical analysis to develop a quantitative understanding of the transient process physics of the binderjet 3D printing. In the first part, maltodextrin based aqueous binder, deployed to ‘direct’ print Ti-6Al-4V powder with the achieved mechanical properties ran
