The purpose of this study is to develop and test an integrated structural gastro-tourism wellbeing model consisting of food-related lifestyle and leisure attitude as a precursor of the consumption enjoyment of the gastro-tourism experience with satisfaction, life domain outcomes, tourism autobiographical memory and life satisfaction as outcomes of the consumption enjoyment.

The conceptual model was assessed with quantitative data collected from tourists based on their deliberate and incidental gastro-tourism experiences (N = 617).

The findings indicated that the enjoyment of gastro-tourism consumption experience significantly influences satisfaction, life domain outcomes, life satisfaction and tourism autobiographical memory. Life domain outcomes and tourism autobiographical memory have enduring influence on life satisfaction over time. Food-related lifestyle and leisure attitude are salient determinants of gastro-tourism wellbeing with their significant influence on consumption experience. Satisfaction with consumption experiences contributes to life satisfaction regardless of the experience type (deliberate versus incidental).

This research extends our knowledge of tourism consumption experience in the domain of gastro-tourism as well as quality of life or wellbeing.

This research has offered an integrated framework to measure the interplays of salient and enduring determinants of gastro-tourism wellbeing. Future studies will benefit from this research as a baseline model linking consumption experience and life satisfaction.

Environmental degradation has emerged as one of the major limitations of industrial revolution and has led to an increased focus towards developing sustainable strategies and techniques. This paper aims to highlight the sustainability aspects of three-dimensional (3D) printing technology that helps towards a better implementation of Industry 4.0. It also aims to provide a brief picture of relationships between 3D printing, Industry 4.0 and sustainability. The major goal is to facilitate the researchers, scholars, engineers and recommend further research, development and innovations in the field.

The various enabling factors for implementation of Industry 4.0 are discussed in detail. Some barriers to incorporation of 3D Printing, its applications areas and global market scenario are also discussed. A through literature review has been done to study the detailed relationships between 3D printing, Industry 4.0 and sustainability.

The technological benefits of 3D printing are many such as weight savings, waste minimization and energy savings. Further, the production of new 3D printable materials with improved features helps in reducing the wastage of material during the process. 3D printing if used at a large scale would help industries to implement the concept of Industry 4.0.

This paper focuses on discussing technological revolution under Industry 4.0 and incorporates 3D printing-type technologies that largely change the product manufacturing scenario. The interrelationships between 3D printing, Industry 4.0 and sustainability have been discussed.
