“…However, the construction of 3D hollowed network structures of in vitro BBB models has not been achieved. A similar limitation representing a significant challenge in the biofabrication of normal vasculature has been addressed using sophisticated 3D printing and bioprinting methods, including inkjet, laser-assisted, micro-extrusion, and vat-polymerization bioprinting ( Aazmi et al., 2021 ; Santoni et al., 2021 ; Wang et al., 2021 ; Zhu et al., 2021b ).…”

“…The recent efforts made by numerous scientists to “imitate” these organs have formed many research fields, including 3D bioprinting, [ 205 , 206 , 207 ] tissue engineering, [ 202 ] organ‐on‐a‐chip [ 208 ] or 3D printed microfluidic devices, [ 209 ] and even the 3D printing of biomimetic materials and structures. [ 210 ] These studies are closely associated with organ models, while the difference is whether cells are involved or not. The developments of these similar fields are not independent, but on mutual promotion and common progress with others.…”

Physical organ models are the objects that replicate the patient-specific anatomy and have played important roles in modern medical diagnosis and disease treatment. 3D printing, as a powerful multi-function manufacturing technology, breaks the limitations of traditional methods and provides a great potential for manufacturing organ models. However, the clinical application of organ model is still in small scale, facing the challenges including high cost, poor mimicking performance and insufficient accuracy. In this review, the mainstream 3D printing technologies are introduced, and the existing manufacturing methods are divided into "directly printing" and "indirectly printing", with an emphasis on choosing suitable techniques and materials. This review also summarizes the ideas to address these challenges and focuses on three points: 1) what are the characteristics and requirements of organ models in different application scenarios, 2) how to choose the suitable 3D printing methods and materials according to different application categories, and 3) how to reduce the cost of organ models and make the process simple and convenient. Moreover, the state-of-the-art in organ models are summarized and the contribution of 3D printed organ models to various surgical procedures is highlighted. Finally, current limitations, evaluation criteria and future perspectives for this emerging area are discussed.

“…One solution is 3D printing of custom shoe midsole, where 3D scanning techniques helps in getting the exact shape and size of the foot which act as input to design. Custom soles are more suitable for plantar structure of patient[ 16 ] and can further be improved if traditional support structure is optimized; therefore, further damage reduction at a lower cost, material waste, and fabrication time[ 17 , 18 ].…”

This study introduces a design procedure for improving an individual’s footwear comfort with body weight index and activity requirements by customized three-dimensional (3D)-printed shoe midsole lattice structure. This method guides the selection of customized 3D-printed fabrications incorporating both physical and geometrical properties that meet user demands. The analysis of the lattice effects on minimizing the stress on plantar pressure was performed by initially creating various shoe midsole lattice structures designed. An appropriate common 3D printable material was selected along with validating its viscoelastic properties using finite element analysis. The lattice structure designs were analyzed under various loading conditions to investigate the suitability of the method in fabricating a customized 3D-printed shoe midsole based on the individual’s specifications using a single material with minimum cost, time, and material use.
