“…108 As per the literature discussion, PLA printed part surface as compared to ABS can be easily treated using this method. [109][110][111] Chen et al, 112 in his study exposed Cu fibre reinforced PLA composite to 5W power laser beam of 200 μm diameter. It was observed that surface quality as well as • The treatment reduces the staircase effect and layer thickness of product mechanical performance of the composite gets enhanced.…”

Fused deposition modeling (FDM) is one of the leading emerging technologies of Industry 4.0, which has been employed to develop sustainable engineering products, customized implants and sophisticated biomedical devices. However, the mechanical strength and durability of 3D printed parts is still lower than its conventional counterparts, which restrict its widespread use. In this regard, the use of short fibres (i.e. natural or artificial) and advanced nanomaterials to reinforce the existing polymer matrix has been drastically increased to improve the load bearing capacity of FDM printed parts. Hence, this article aims to provide a systematic review on thermoplastic composite structure prepared through FDM technology and summarizes the current knowledge about the use of various additives to improve the overall quality FDM parts. Moreover, the common defects associated with FDM printed composite structures and the methods required to improve the quality of FDM composite parts are discussed in this article.

Background Data on the birth prevalence of congenital anomalies in low- and middle-income countries report wide variations in prevalence estimates. We conducted a scoping review to identify the sources of bias in studies reporting birth prevalence of congenital anomalies in World Health Organization South-East Asia region (SEAR) countries. Methods PubMed and Google Scholar databases were screened for relevant literature. Data on study characteristics and sources of bias was extracted. A narrative synthesis of the data is reported using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses extension for Scoping Reviews checklist. A checklist for reporting studies on birth prevalence of congenital anomalies (CD-Checklist) was developed. Results The literature search retrieved 47 articles. Birth prevalence varied from 0.21% to 9.68%. Sampling bias was evident as studies were single hospital studies, lacked relevant description of sample, did not justify sample size or describe the process of sampling. Information bias was identified as studies did not mention classification system used, and failed to clearly distinguish between number of malformations and babies with malformations. Observer and reporting bias were noted. Conclusions Several sources of bias introduce variations in birth prevalence reports of congenital anomalies in SEAR countries. A checklist (CD-Checklist) has been suggested which can guide investigators to minimize the risk of bias in studies.
