3D printing is one of the most speedily growing technologies in different sectors including the fashion industry. Though it is being implemented in the fashion industry, the application of 3D printing technology has been relatively slow in this sector owing to aspects like limitations related to materials, problems in the procurement of the technology, and concerns about whether the product should be worn on the human body [1].
Many researchers in the past have conducted studies on the use of 3D printing in the fashion industry. Vanderploeg et al., (2017) [2] conducted research on different applications of 3D printing in the fashion industry, Sun & Zhao, (2017) [3] presented a model on the impact and challenges of the use of 3D printing in the fashion industry, Chun, (2017) [4] studied the use of 3D printing technology to cultivate new designs, D. Sun & Valtasa, (2019) [5] conducted research on the integration of 3D printing technology into fashion clothing production processes, McCormick et al., (2020) [6] studied the Chinese fashion market for use of 3D printing, Spahiu et al., (2020) [7] researched 3D printing techniques.
Both in the fashion industry and in 3D printing, the material used plays a very important role. In this direction, one material that has started to grab the attention of the researchers, producers, and customers is thermoplastic polyurethane (TPU). It is known for its outstanding material properties like tear resistance, resistance to chemicals, abrasion resistance, skin compatibility, large elongation break, resistance to ozone, low-temperature resistance, resistance to oxygen, low long-term deformation rate, resistance to oil and fuels, antimicrobial properties, resistant to fungus, soft elasticity, and excellent bending and tension strength [9,10]
TPU can be coated onto a piece of fabric to deliver protection, comfort, and aesthetic values to the fabric. Owing to these properties and properties enlisted in Figure 1, TPU is considered to be a good choice for making garments and textiles. Owing to these aspects, many researchers have studied the use of TPU material for 3D printing fashion products. Kim et al., (2019) [1] and Han & Kim, (2018) [11] studied the use of TPU-based material for 3D printing fashion products, Jin & Li, (2020) [12] researched the development of 3D printing clothing using TPU material, Jeong et al., (2021) [13] used TPU material in 3D printing for developing parametric design in fashion products. Although TPU has certain limitations such as its rough feel and limitations in creating diverse designs such as those with severe curves, its biggest advantage is that it is sustainable, which makes it worth adopting.
Scree Plot for (a) Benefits (b) Challenges (c) Challenges Post Removal of Item C8 (d) Motivation to adopt and (e) Attitude towards adoption of TPU- Based 3D Printed Fashion Clothes
While many have studied 3D printing technology using TPU material in the fashion industry from different perspectives, fewer researchers have addressed the actual adoption of TPU-based 3D printing in the fashion industry. Thus, the present research has been focused to propose an adoption model for TPU-based 3D-printed fashion clothes.
The Chinese fashion industry is growing rapidly. This can be attributed to the fact that the purchasing power of the Chinese population is at its peak. Now, fashion has become an important for the Chinese population, and clothing is no longer a mere necessity. Moreover, fashion is now one of China's most lucrative industries. Not only local, but also foreign companies are looking for ways to get a strong foothold in the fashion market of the world's most populous country. Today, the Chinese fashion market is the second-largest apparel market in the world with an estimated value of USD 2 billion [14]. This scenario of the Chinese fashion industry makes it vital to study TPU-based 3D printed fashion clothes because TPU has the potential to be the future of fashion and the Chinese fashion market, which holds the maximum potential in the world as it has the biggest consumer market).
TPU is a comparatively new topic in the fashion world, which is why only a moderate amount of research has been conducted on it. It holds a bright future as the world is moving towards sustainability. The research that has been conducted so far on TPU usually discusses the challenges and/or opportunities of adopting TPU. But no research till now has focused on how to adopt it even though the material holds such huge potential. Thus, it is imperative to provide a framework for the adoption of TPU in the fashion industry so that the industry is able to completely utilize its excellent mechanical properties, and thereby make it more suitable and sustainable while dealing with as few hindrances as possible. Thus, the present research has focused on providing a conceptual framework for the adoption of TTPU-based 3D printed material.
The present research is based on providing a conceptual framework for the adoption of TPU-based 3D printed material. Adoption is done on two fronts – namely, the customer front the and producer front. On the side of the customer, adoption depends on consumer behaviour. Consumer behaviour is dependent on motivation to buy and customer attitude [15, 16, 17, 18, 19]. In the same direction, Duggal, (2018) [20] found that understanding consumer motivation has become very important as it facilitates the producer in understanding the focus of the customer. Furthermore, the researcher stated that customer attitude facilities understanding the reason behind customer behaviour. This means the motivation to buy and customer attitude are significant factors to assess when discussing adoption. Also, when it comes to producers, the challenges and benefits associated with adoption impact adoption the most [3, 21, 22]. In this direction, Berger et al., (2020) [23] stated that for the successful adoption of any product, it is important to assess the perceived challenges and benefits on the customer side. This means it is imperative to assess the challenges and benefits of adoption. Thus, the present research has focused on these four factors namely motivation to buy and customer attitude, and the challenges and benefits associated with the adoption of TPU-based 3-D printed fashion clothes.
In the present research, the deductive approach has been used. The study was conducted in China. Two populations of respondents have been used. The first is named “Producers”. The producer population includes the managerial level employees of different textile companies associated with 3D printing on TPU material in China, working in departments – namely, Fabric Testing Lab, Production Planning and Control, Quality Control department and Printing departments. The second population is “Customers”. The Customer population includes present and potential buyers who approach different fashion houses in China to enquire about and buy 3D printing fashion clothes made of TPU material.
For the administration of questionnaires for producers, they were e-mailed to the managerial employees in form of Google forms. The e-mail ids of the respondents were collected from the HR department of their associated companies. A total of 100 questionnaires were e-mailed out, of which 87 filled questionnaires were received. Furthermore, for the administration of questionnaires for customers, the fashion houses dealing with 3D-printed TPU-based clothes were approached and asked their customers to fill them in. The items used for the study are presented in Table 1 below-

Here, high extraction values (>0.5) were obtained which indicate that the factors thus received are good as the proportion of each variable's variance that can be explained by the retained factors are high.
The total number of factors retained in the total variance explained test is two. Furthermore, these two factors account for 77.85% of the variance, which is a respectable number pointing towards the credibility of the retained factors. The number of factors retained can further be observed in the Scree Plot presented in Figure 1(a). It can be observed in Figure 1(a) that factor 1 and factor 2 possess the highest Eigenvalues, thereby contributing to the highest variance. Post the second factor, the line is almost flat, meaning each successive factor is accounting for smaller and smaller amounts of the variance.

Since the study reported appropriate values for KMO-Bartlett Test, the researchers moved ahead with Factor Analysis as follows
Here, high extraction values (>0.5) were obtained, which indicates that the factors thus received are good as the proportion of each variable's variance, which can be explained by the retained factors being high except for item C8 (0.202).
The total number of factors retained in the total variance explained test is two. Also, these two factors account for 74.121% of the variance, which is a respectable number pointing towards the credibility of the retained factors. The number of factors retained can further be observed in the Scree Plot (Figure 1 b). It can be observed in Figure 1 (b) that factor 1 and factor 2 possess the highest Eigenvalues, thereby contributing to the highest variance. Post the second factor, the line is almost flat, meaning each successive factor is accounting for smaller and smaller amounts of the variance.
Table 5 presents the items segregated under two factors. It can be seen C3 lies under factor 2 while all other items lie in factor 1. Further, the correlation value of C8 was extremely small, which is less than 0.5 owing to which it has not been categorized under any factor.

Re-running the test after the removal of item C8. Post removal of C8, the value of KMO increased from 0.889 to 0.904.
Here, high extraction values (>0.5) were obtained which indicate that the factors thus received are good as the proportion of each variable's variance that can be explained by the retained factors are high.
Post-removal of item C8, the total number of factors retained is still two. Further, the variance accounted for by these two factors post-removal of C8 increased from 74.121% of variance to 82.925% thereby enhancing the credibility of the retained factors. This depicts an improvement in the quality of the retained factors.
It can be observed in Figure 1(c) that factor 1 and factor 2 possess the highest Eigenvalues, thereby contributing to the highest variance. Thus, not much difference was observed from the Scree plot with C8 (Figure 1c).
Table 7 presents the items segregated under two factors. It can be seen C3 lies under factor 2 while all other items lie in factor 1 which is the same as was the case with a rotated component matrix with item C8 (Table 10). Further, the correlation value of C3 can be observed to be increased from 0.898 to 0.996 post-removal of C8. On analysing the items under factor 1 and factor 2 (Table 1), it was found that the items under factor 1 were TPU material related challenges while those under factor 2 were printer related. Thus, factor 1 was named TPU Material Related Challenges while factor was called Printer Related Challenge.

Figure 1 presents the Scree Plot of all the above factors.
To assess the association of the above factors on “Adoption of TPU-Based 3D Printed Fashion Clothes” it is imperative to determine the factor structure (model). For doing so, exploratory factor analysis (EFA) has been conducted. EFA will facilitate variable reduction thereby identifying the number of latent constructs and the underlying factor structure of a set of variables.
As per the perception of the researcher, all the above factors might lead to the adoption of TPU-based 3D printed fashion clothes. Thus EFA has been conducted to establish a model for the same based on the factors extracted via factor analysis conducted in previous sections.
The model thus obtained post exploratory factor analysis has been presented in Figure 2. The analysis of model fit has been conducted as follows.
Proposed Model for Adoption of TPU-Based 3D Printed Fashion Clothes
Minimum discrepancy per degree of freedom (CMIN/DF)< 3 indicates an acceptable fit between the hypothetical model and sample data [24]. Thus, the proposed model of the present research has an acceptable fit based on CMIN/DF (2.621, Table 12).

NFI value between 0.8 and 0.9 is considered to be acceptable [25]. Thus, the NFI value (0.80, Table 12) in the present research makes the proposed model acceptable. Further, a TLI value of more than 0.9 is considered to be a good fit [25] but in the present research, the TLI value is lower (Table 12). Thus, the research has considered other matrices to base the results on. Finally, a CFI value between 0.8 and 0.9 is considered acceptable which is the case with present research as the CFI value obtained is 0.856.
For FMIN Model Fit Indices, the more the value is close to 0, the better the model fit [26]. Since the values of FMIN Model Fit Indices in the present research are close to zero, it points towards a good model fit.
According to MacCallum et al., (1996) [27], the RMSEA value of less than 0.08 is an acceptable fit, thereby making the proposed model in the present research acceptable.
Since all the model fit indices are within acceptable limits, the model can be stated to be a good fit. Thus, the proposed model has been presented in Figure 2.
By observing the model fit indices, the model seems to be a good fit with the observed data. Thus, the adoption of the framework on TPU-based 3D printed fashion clothes (Figure 2) has been suggested in the present research. As per the findings of the present research, on a broader spectrum, the adoption of TPU-based 3D printed fashion clothes in China is dependent on challenges and benefits faced by producers along with the motivation of customers and their attitude towards adoption. The study found the challenges faced by producers, which impact the adoption of TPU-based 3D printed fashion clothes to be of two types – namely, TPU material-based challenges and printer-based challenges.
The benefits were also found to be of two types – namely, customer-related benefits and strength-related benefits. The motivation for the customers to adopt TPU-based 3D printed fashion clothes in China was also found to be of two types: brand-centric and customer-centric. Finally, the attitude of customers towards TPU-based 3D printed fashion clothes was of 4 types – namely, subjective norm, personal norm, environmental concern, and customer knowledge and intention. It is imperative to assess the application of this model. Thus, for future research, it is recommended that this model is applied in a real-time market, on a pilot level, to understand its applicability and effectiveness. Furthermore, it is necessary to conduct an assessment of the suitability of TPU for 3D printing and for the textile industry for future research.
