The purpose of this study is to identify, analyse and model the post-processing barriers of 3D-printed medical models (3DPMM) printed by fused deposition modelling to overcome these barriers for improved operational efficiency in the Indian context.

The methodology used interpretive structural modelling (ISM), cross-impact matrix multiplication applied to classification (MICMAC) analysis and decision-making trial and evaluation laboratory (DEMATEL) to understand the hierarchical and contextual relations among the barriers of the post-processing.

A total of 11 post-processing barriers were identified in this study using ISM, literature review and experts’ input. The MICMAC analysis identified support material removal, surface finishing, cleaning, inspection and issues with quality consistency as significant driving barriers for post-processing. MICMAC also identified linkage barriers as well as dependent barriers. The ISM digraph model was developed using a final reachability matrix, which would help practitioners specifically tackle post-processing barriers. Further, the DEMATEL method allows practitioners to emphasize the causal effects of post-processing barriers and guides them in overcoming these barriers.

There may have been a few post-processing barriers that were overlooked by the Indian experts, which might have been important for other country’s perspective.

The presented ISM model and DEMATEL provide directions for operation managers in planning operational strategies for overcoming post-processing issues in the medical 3D-printing industry. Also, managers may formulate operational strategies based on the driving and dependence power of post-processing barriers as well as the causal effects relationships of the barriers.

This study contributes to identifying, analyzing and modelling the post-processing barriers of 3DPMM through a combined ISM and DEMATEL methodology, which has not yet been reviewed. This study also contributes to decision makers developing suitable strategies to overcome the post-processing barriers for improved operational efficiency.

This study aims to identify 3D-printed medical model (3DPMM) supply chain barriers that affect the supply chain of 3DPMM in the Indian context and investigate the interdependencies between the barriers to establish hierarchical relations between them to improve the supply chain.

The methodology used interpretive structural modeling (ISM) and a decision-making trial and evaluation laboratory (DEMATEL) to identify the hierarchical and contextual relations among the barriers to the 3DPMM supply chain.

A total of 15 3DPMM supply chain barriers were identified in this study. The analysis identified limited materials options, slow production speed, manual post-processing, high-skilled data analyst, design and customization expert and simulation accuracy as the significant driving barriers for the medical models supply chain for hospitals. In addition, the authors identified linkage and dependent barriers. The present study findings would help to improve the 3DPMM supply chain.

There were no experts from other nations, so this study might have missed a few 3DPMM supply chain barriers that would have been significant from another nation’s perspective.

ISM would help practitioners minimize 3DPMM supply chain barriers, while DEMATEL allows practitioners to emphasize the causal effects of 3DPMM supply chain barriers.

This study minimizes the 3DPMM supply chain barriers for medical applications through a hybrid ISM and DEMATEL methodology that has not been investigated in the literature.

The purpose of this paper is to provide systematic empirical evidence on the health planning through Village Health Sanitation and Nutrition Committees (VHSNCs) in India.

A micro-level study was carried out using qualitative study design. Data were collected through in-depth interviews with 105 respondents selected from 42 VHSNC sites. A thematic analytical framework approach was used to analyse the data.

The research results indicate that VHSNCs are playing a significant role in health planning. However, the committee meetings are not organised by the committee members on the regular basis. Most of the VHSNC members do not make village health plans. There are some challenges associated with the functioning of VHSNCs like insufficient resources, lack of people’s interest, insignificant attention and the unfair behaviour of the Panchayati Raj leaders.

The implications of the findings suggest that VHSNCs play a significant role in health planning. However, the leadership is ineffective due to their partial capabilities and approach that generate non-conducive environment. Studies of such nature will be helpful for policy makers in understanding the current situation and micro-level picture of VHSNC and also in analysing it in the existing health system.

VHSNC functions with a broader concern and cover range of social determinants at the village level. This study provides empirical evidence on the VHSNCs as lowest part of the health system.

This paper aims to explore the challenges and benefits arising from the involvement of Panchayati Raj Institutions (PRIs) in the provisioning of primary healthcare in a decentralised health system of India.

A qualitative study design was used in this study. Data were collected through semi-structured interviews from 89 respondents selected from nine primary health centres across the district. A thematic analytical framework approach was used to analyse the data.

The research results indicate that there are several challenges resulting from PRIs involvement, including prioritisation of service providers and users, coercive unethical work and lack of communication. However, there are some benefits associated with the involvement of the PRIs in service provisioning, including improved availability and regularity of healthcare providers at the health centres.

The implications of the findings suggest that the PRIs play an important role in healthcare provisioning; however, their involvement is ineffective due to their partial capabilities and approach, which creates a non-conducive environment.

Health issues are among the most important human concerns, and recognising and addressing the grassroot challenges help to locate, and overcome the challenges that hinder the smooth healthcare provisioning process.

National Rural Health Mission has recognised the PRIs as a platform to promote decentralised health planning and for achieving its goals in India. The PRIs are significantly involved in planning, monitoring and provisioning of primary healthcare services at grassroot level. This paper addresses the challenges and benefits that emerged due to their involvement.

The 12^th South Asian Games were held in India in Guawhati and Shillong in February 2016, after repeated rescheduling. There were a number of challenges to organizing the games such as lack of infrastructure, legacy of corruption from past games, shortage of time etc. However, the games were held within 90 days of the announcement of venues and final dates. Sri Yadav, the Secretary, Department of Sports wants to understand the key drivers of success behind organizing the event. He also wants to understand how the success of Indian athletes at SAG could be leveraged for success at larger events.

The purpose of this paper is to study the functionality of additively manufactured (AM) parts, mainly depending on their dimensional accuracy and surface finish. However, the products manufactured using AM usually suffer from defects like roughness or uneven surfaces. This paper discusses the various surface quality improvement techniques, including how to reduce surface defects, surface roughness and dimensional accuracy of AM parts.

There are many different types of popular AM methods. Unfortunately, these AM methods are susceptible to different kinds of surface defects in the product. As a result, pre- and postprocessing efforts and control of various AM process parameters are needed to improve the surface quality and reduce surface roughness.

In this paper, the various surface quality improvement methods are categorized based on the type of materials, working principles of AM and types of finishing processes. They have been divided into chemical, thermal, mechanical and hybrid-based categories.

The review has evaluated the possibility of various surface finishing methods for enhancing the surface quality of AM parts. It has also discussed the research perspective of these methods for surface finishing of AM parts at micro- to nanolevel surface roughness and better dimensional accuracy.

This paper represents a comprehensive review of surface quality improvement methods for both metals and polymer-based AM parts.
