“…Given their central role, it would make sense to find a fast, inexpensive, and accurate way to produce tailored complex systems, not only to broaden the application range of these materials but also to give them a more ecological character. This versatility can be achieved with 3D printing methods, and especially by vat photopolymerization, one of the most accurate technologies. , Nevertheless, since pure carbon cannot be melted, sintered, or polymerized, this particular element is not directly applicable in additive manufacturing. Thus, most 3D-printed carbon materials are obtained by printing a carbon precursor, followed by a pyrolysis step.…”

Carbon structures, unlike metals or polymers, can hardly be directly implemented in additive manufacturing, and their sustainable nature is extremely limited. In this work, we demonstrate that porous carbon structures can be obtained by laser stereolithography of acrylate–tannin mixed resins, followed by a pyrolysis step. By adjustment of the initial acrylate/tannin ratio in the resin, the density and volume shrinkage of the resultant carbon, and consequently the mechanical properties of the corresponding carbon-based architectures, could be modified. The moderate electrical conductivity of the structures, reaching about 7 S cm–1, and their broad-band absorption in microwaves open up possibilities for electrochemical or electromagnetic applications. Thus, the possibility of obtaining complex freestanding structures with imperceptible warpage, low volume shrinkage, and adjustable density offers an opportunity to develop 3D-printed carbon materials with a significant proportion of bio-based precursors, which can be easily adapted for a large number of applications.

“…3D printing opens up new design possibilities for the fabrication of complex carbon materials with considerable application potential with specific customisation [ 1 , 2 ]. Obtaining a porous carbon material in 3D through a multi-step process, i.e., carbon precursor formulation, printing, and pyrolysis, is easily achievable with stereolithography (SLA), one of the most accurate 3D printing technologies [ 3 , 4 ].…”

Experimental Design Optimization of Acrylate—Tannin Photocurable Resins for 3D Printing of Bio-Based Porous Carbon Architectures

In this work, porous carbons were prepared by 3D printing formulations based on acrylate–tannin resins. As the properties of these carbons are highly dependent on the composition of the precursor, it is essential to understand this effect to optimise them for a given application. Thus, experimental design was applied, for the first time, to carbon 3D printing. Using a rationalised number of experiments suggested by a Scheffé mixture design, the experimental responses (the carbon yield, compressive strength, and Young’s modulus) were modelled and predicted as a function of the relative proportions of the three main resin ingredients (HDDA, PETA, and CN154CG). The results revealed that formulations containing a low proportion of HDDA and moderate amounts of PETA and CN154CG gave the best properties. Thereby, the optimised carbon structures had a compressive strength of over 5.2 MPa and a Young’s modulus of about 215 MPa. The reliability of the model was successfully validated through optimisation tests, proving the value of experimental design in developing customisable tannin-based porous carbons manufactured by stereolithography.

“…Carbon-based nanomaterials have been frequently incorporated into bioinks due to their excellent electrical and mechanical properties ( Blyweert et al, 2021 ). In addition to their ability to promote cartilage differentiation, they have numerous applications in nerve and muscle tissue engineering ( Lu et al, 2021 ).…”

As a microenvironment where cells reside, the extracellular matrix (ECM) has a complex network structure and appropriate mechanical properties to provide structural and biochemical support for the surrounding cells. In tissue engineering, the ECM and its derivatives can mitigate foreign body responses by presenting ECM molecules at the interface between materials and tissues. With the widespread application of three-dimensional (3D) bioprinting, the use of the ECM and its derivative bioinks for 3D bioprinting to replicate biomimetic and complex tissue structures has become an innovative and successful strategy in medical fields. In this review, we summarize the significance and recent progress of ECM-based biomaterials in 3D bioprinting. Then, we discuss the most relevant applications of ECM-based biomaterials in 3D bioprinting, such as tissue regeneration and cancer research. Furthermore, we present the status of ECM-based biomaterials in current research and discuss future development prospects.
