Challenges of 3D printing technology for manufacturing biomedical products: A case study of Malaysian manufacturing firms

Abstract

Additive manufacturing has attracted increasing attention worldwide, especially in the healthcare, biomedical, aerospace, and construction industries. In Malaysia, insufficient acceptance of this technology by local industries has resulted in a call for government and local practitioners to promulgate the development of this technology for various industries, particularly for biomedical products. The current study intends to frame the challenges endured by biomedical industries who use 3D printing technology for their manufacturing processes. Qualitative methods, particularly in-depth interviews, were used to identify the challenges faced by manufacturing firms when producing 3D printed biomedical products. This work was able to identify twelve key challenges when deploying additive manufacturing in biomedical products and these include issues related to binder selection, poor mechanical properties, low-dimensional accuracy, high levels of powder agglomeration, nozzle size, distribution size, limited choice of materials, texture and colour, lifespan of materials, customization of fit and design, layer height, and, lastly, build-failure. Furthermore, there also are six challenges in the management of manufacturing biomedical products using 3D printing technology, and these include staff re-education, product pricing, limited guidelines, cyber-security issues, marketing, and patents and copyright. This study discusses the reality faced by 3D printing players when producing biomedical products in Malaysia, and presents a primary reference for practitioners in other developing countries.

Exploring Regional Advanced Manufacturing and Its Driving Factors: A Case Study of the Guangdong–Hong Kong–Macao Greater Bay Area

“…The manufacturing structure of the Guangdong–Hong Kong–Macao Greater Bay Area (GBA) is constantly being upgraded, especially with intelligent manufacturing [ 1 , 2 ], equipment [ 3 ], and biomedicine [ 4 ]. However, in terms of the “reindustrialization” strategy [ 5 ] carried out by the United States, the Sino–United States trade war exposed a lack of key technologies in China’s manufacturing industry, giving it a disadvantage in international competition.…”

3D Silk Fiber Construct Embedded Dual-Layer PEG Hydrogel for Articular Cartilage Repair – In vitro Assessment

“…All these methods, the fiber spinning and construction of 3D layers are processed at the same time. However, limitations in materials choice and trial and error process would be the difficulties of these methods (Shahrubudin et al, 2020 ). In our case, we use off-the-shelf fibers and then construct the 3D layer.…”

Mechanical Properties of Porous Structures for Dental Implants: Experimental Study and Computational Homogenization

“…Small dental implants fall into this category. Therein, the size of a typical microstructural load-bearing element is the principal obstacle in producing reliable and patient-safe implants [ 52 ]. Some of the issues regarding the needs for both experimental and theoretical studies are presented in this paper.…”
