3D printing of bone tissue engineering scaffolds
Open accessAbstract
Tissue engineering is promising in realizing successful treatments of human body tissue loss that current methods cannot treat well or achieve satisfactory clinical outcomes. In scaffold-based bone tissue engineering, a high performance scaffold underpins the success of a bone tissue engineering strategy and a major direction in the field is to produce bone tissue engineering scaffolds with desirable shape, structural, physical, chemical and biological features for enhanced biological performance and for regenerating complex bone tissues. Three-dimensional (3D) printing can produce customized scaffolds that are highly desirable for bone tissue engineering. The enormous interest in 3D printing and 3D printed objects by the science, engineering and medical communities has led to various developments of the 3D printing technology and wide investigations of 3D printed products in many industries, including biomedical engineering, over the past decade. It is now possible to create novel bone tissue engineering scaffolds with customized shape, architecture, favorable macro-micro structure, wettability, mechanical strength and cellular responses. This article provides a concise review of recent advances in the R & D of 3D printing of bone tissue engineering scaffolds. It also presents our philosophy and research in the designing and fabrication of bone tissue engineering scaffolds through 3D printing.

Extrusion-based 3D printing is a common strategy because of low cost, simple and eco-friendly fabrication, high availability of materials, and diverse raw material forms.
“extrusion-based 3D printing is a common strategy because of low cost, simple and eco-friendly fabrication, high availability of materials (metals, ceramics, polymers, hydrogels and their composites) and diverse raw material to process (wires, pellets, and powders) [18][19][20]”
From A strategy to tailor the mechanical and degradation properties of PCL-PEG-PCL based copolymers for biomedical application (2023) · cites this paper as [18]
The section on polyester scaffolds at high temperature says FDM is often adopted because it is low-cost, simple and eco-friendly, and that it uses wires or pellets. The Composition section describes ceramics, hydrogels, polymers and composites as printing materials and mentions powders, but the paper does not establish that extrusion-based printing accommodates the full listed range, particularly metals and powders, or that material availability itself explains its use.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
