Beschreibung
Zusammenfassung:	Embodiments of the present disclosure include methods of simultaneously manufacturing two or more hydrogel constructs (e.g., tubular hydrogel constructs). In some embodiments, the method comprises one or more of the following steps: providing a vat comprising a bio-ink composition containing one or more monomers and/or one or more polymers; applying electromagnetic radiation from an electromagnetic radiation source to cure a layer of the hydrogel constructs (e.g., tubular hydrogel constructs); and applying electromagnetic radiation from the electromagnetic radiation source one or more additional times to produce one or more additional layers of the hydrogel constructs (e.g., tubular hydrogel constructs). Des modes de réalisation de la présente divulgation comprennent des procédés de fabrication simultanée de deux constructions d'hydrogel ou plus (par exemple, des constructions d'hydrogel tubulaires). Dans certains modes de réalisation, le procédé comprend une ou plusieurs des étapes suivantes consistant : à fournir une cuve comprenant une composition d'encre biologique contenant un ou plusieurs monomères et/ou un ou plusieurs polymères ; à appliquer un rayonnement électromagnétique à partir d'une source de rayonnement électromagnétique pour durcir une couche des constructions d'hydrogel (par exemple, des constructions d'hydrogel tubulaire) ; et à appliquer un rayonnement électromagnétique à partir de la source de rayonnement électromagnétique une ou plusieurs fois supplémentaires pour produire une ou plusieurs couches supplémentaires des constructions d'hydrogel (par exemple, des constructions d'hydrogel tubulaires).
