Application and Development of Modern 3D Printing Technology in the Field of Orthopedics

Abstract

3D printing, also known as additive manufacturing, is a technology that uses a variety of adhesive materials such as powdered metal or plastic to construct objects based on digital models. Recently, 3D printing technology has been combined with digital medicine, materials science, cytology, and other multidisciplinary fields, especially in the field of orthopedic built-in objects. The development of advanced 3D printing materials continues to meet the needs of clinical precision medicine and customize the most suitable prosthesis for everyone to improve service life and satisfaction. This article introduces the development of 3D printing technology and different types of materials. We also discuss the shortcomings of 3D printing technology and the current challenges, including the poor bionics of 3D printing products, lack of ideal bioinks, product safety, and lack of market supervision. We also prospect the future development trends of 3D printing.

Development of heparinized and hepatocyte growth factor‐coated acellular scaffolds using porcine carotid arteries

“…This result is consistent with previous observations that increased cross-linking inevitably leads to a decrease in porosity in network scaffolds. [25][26][27] Therefore, increased porosity compromises the mechanical properties of the scaffolds. For an optimal scaffold system, there should be a balance between the biomechanical and mass transport functions.…”

Dual nozzle 3D printing strategy to improve the surface quality of continuous glass fiber reinforced polyamide 6 composites

“…Continuous glass fiber reinforced PA6 (CGF/PA6) filament was self-prepared by a melt impregnation process. Short glass fiber reinforced PA6 (SGF/PA6) filament with 25 wt% glass fiber content was supplied by JF Polymers Co., Ltd., Suzhou, China, which had a diameter of 1.75 mm and density of 1.2 g/cm 3 . The antioxidant (1098/168) used in this work was provided by Dongguan Kangjin New Material Technology Co., Ltd. China.…”

“…3D printing is an additive manufacturing method, which enables rapid processing, manufacturing of precision parts with complex shapes and individualized production without mold 1,2 . 3D printing can effectively shorten the production cycle of parts, improve material utilization, reduce the manufacturing costs and break through the technical bottleneck that traditional manufacturing methods cannot achieve one‐time molding of single complex parts 3–5 . Compared with common 3D printing technologies, fused deposition modeling (FDM) 3D printing is easy to use and supports a variety of material types, which has a very broad application prospect 6,7 …”

[3][4][5] Compared with common 3D printing technologies, fused deposition modeling (FDM) 3D printing is easy to use and supports a variety of material types, which has a very broad application prospect. 6,7 3D printed products made of a single resin material have the defects of low strength and modulus, which cannot meet the performance requirements of automotive parts, medical devices, and other high-performance products.…”

Future directions in ceramic additive manufacturing: Fiber reinforcements and artificial intelligence

“…In order to assess and analyze recent review articles in this area, a Scopus search was conducted in April 2023 for the specific time frame of 2018–2023. This search resulted in 165 review articles on ceramic additive manufacturing or some subset of that topic 1,3–166 . Figure 1 shows a graphical representation of the number of review articles separated into five focus areas.…”
