The purpose of this paper is to investigate the effects of aging, pre‐conditioning, and build orientation on the mechanical properties of test samples fabricated using stereolithography (SL) and a commercially available resin.

American Society for Testing and Materials (ASTM) Standard D638 Type I specimens were manufactured in a Viper si2 SL system using WaterShed™ 11120 resin. The specimens were manufactured in two different build setups, designed to fit batches of 18 or 24 specimens with different build orientations. The specimens were randomly tested in tension, and a design of experiments (DOE) was used to determine the effect of aging (4, 30 or 120 days), pre‐conditioning (ambient, desiccant, or ASTM recommended conditioning), and build orientation (flat, on an edge, or vertical) on the ultimate tensile stress (UTS) and elastic modulus (E) of SL fabricated samples. Additionally, the fractured samples were imaged using scanning electron microscopy (SEM) to characterize the fractured surfaces.

Results showed that aging, pre‐conditioning, and build orientation each had an effect on the mechanical properties of the SL samples. In general, the samples aged at the shortest time frame (4 days) and the samples preconditioned according to ASTM recommendations had the lowest values of UTS. Regarding the effect of build orientation, the specimens built flat (with layers oriented along the thickness of the sample) had the lowest UTS and E values and the mechanical properties were statistically different from those built vertically or on an edge. The specimens built in the vertical orientation (with layers oriented along the length of the sample) had the highest values of UTS and E, yet the mechanical properties of the samples built on an edge (with layers oriented along the width of the sample) were not statistically different from the samples built vertically. SEM images of the fractured specimens showed fracture surfaces typical of polymers with a mirror zone and changes in surface texture from smooth to coarse.

The research was limited to a single commercially available resin. Through a statistical DOE approach, statistically significant differences in mechanical properties of SL fabricated samples were found as functions of aging, pre‐conditioning, and build orientation. These results can assist the ASTM F42 Committee with developing test standards specific to SL and the additive manufacturing community.

The statistical analyses presented here can help identify and classify the effects of fabrication, storage, and conditioning parameters on mechanical properties for SL fabricated parts. Understanding how the mechanical properties of SL resins are affected by different parameters can help improve the use of SL for a variety of applications including direct manufacturing of end‐use products.

The objective of this study is to investigate the use of a fibre Bragg grating (FBG) sensor for measuring of curing strains that develop during the solidification of a photocurable resin used in 3D microfabrication.

The followed approach consists of embedding a 1,300 nm FBG into a cylindrical specimen, fabricated into a transparent mould, being exposed to ultraviolet laser light. The further development of the cure induced strains under thermal treatment was also studied by post‐conditioning the cylindrical specimen in an oven at 70°C.

The experimental results demonstrate the capability of the FBG sensor to provide useful information on the strain build‐up during laser solidification and their post‐cure evolution under the presence of a thermal environment.

Future work should involve the use of smaller diameter FBG sensors in microstereolithography built parts.

It is shown that considerable cure strains are developed at the end of the photo‐polymerisation process that eventually can affect the structural resolution of final parts fabricated by microstereolithography.

The presented method can be used to investigate other photopolymers used in micro‐stereolithography.

The purpose of this study is to employ a user-centered approach to identify subgroups of people with similar profiles based on their perceptions of multiple dimensions of digital products' coolness and to test the differences across subgroups in the intention to use these products.

In Study 1, 1,161 adults rated a virtual digital product on four dimensions of coolness. In Study 2, 660 college students made similar ratings and also reported their intention to use a real digital product. Participants' ratings were analyzed using a user-centered approach, namely latent profile analysis.

Study 1 identified groups of participants who had similar profiles of product ratings on the four dimensions of coolness: niche cool, mass cool, uncertain cool and uncool. Study 2 replicated the findings of Study 1 and in addition showed that these groups varied in their intention to use the product and in whether a specific dimension increased or decreased this intention.

The cross-sectional data preclude inferences about causality, calling for experimental or longitudinal research. Additionally, future research should explore whether the results generalize to other product categories and other age groups.

Managers should design digital products, segment the market and develop flexible strategies based on combined responses to dimensions of coolness perception.

The present research employed a user-centered approach to identify groups of people who share similar patterns of coolness perception. This study provides new insight that was not available in variable-centered research.

Building on the theory of brand psychological ownership, this paper aims to explore the mediating role of brand psychological ownership in the relationship between brand personality (innocence/coolness) and consumers’ preferences, as well as identify the boundary conditions of this relationship.

To test the hypotheses, a series of four experiments were conducted in Wuhan, a city in southern China, using questionnaires administered at two universities and two supermarkets. Hypotheses were tested using PLS-SEM in SmartPLS 4.

The results indicate that brand personality, specifically the dimensions of innocence and coolness, has a significant impact on consumers’ brand preferences. Brands with a cool personality are preferred over those with an innocent personality. Moreover, the relationship between brand personality and consumers’ brand preferences is moderated by power motivation and identity centrality.

This study contributes to the literature by differentiating between brand personality of innocence and coolness as two separate constructs and proposing brand psychological ownership as a mechanism through which brand personality affects brand preferences. The study’s samples were drawn from universities and supermarkets in southern China, providing evidence for the significant moderating effects of power motivation and identity centrality on consumers’ brand preferences.

Purpose: Cool, a subjective, socially constructed concept has interested several researchers investigating its nature and successful marketing applications. However, the authors note a lack of studies investigating its perceptions in non-Western cultural contexts. The aims of this study are to investigate the meanings of cool in Tunisia, a North-African, Arab-Muslim emerging country.

Methodology: The authors conducted qualitative research through focus groups with Tunisian consumers. The authors used lexical, thematic, and semiotic analyses to investigate cool meanings.

Findings: Findings show that the term “Cool” in Tunisia is mostly related to lexical synonyms and meanings of lightness and flexibility, fun and amusement, humor, and trendiness rather than originality, divergence, creativity, and uniqueness long argued to be the significations of cool in Western literature, despite their minor presence in our results.

Originality/Value: Results show further evidence that the concept is culturally laden and that the socio-cultural characteristics of Tunisia altered its meanings established in the West, mostly associated to its origins and emergence.

This paper presents an experimental study undertaken to determine the polymerisation‐induced residual stresses generated in stereolithography (SL) built test specimens, by using the hole‐drilling strain gage method of stress relaxation. Experimentally measured strains, using special three‐element strain gage rosettes, were input into the blind‐hole analysis to calculate the induced residual stresses. The mechanical properties of resin specimens fabricated by the solidification process using an epoxy based photopolymer and post‐cured under ultraviolet (UV) and thermal exposure were determined and incorporated into the subsequent drill‐hole analysis. The effect of the pre‐selected fabrication parameters (hatching space and curing depth) and subsequent by the post‐curing procedure (UV, thermal curing) on the magnitude of the recorded strains is also presented.

Cool has been studied mostly in consumer samples drawn from Western countries. This study was inspired by paucity of literature on “cool” in an Indian context. There is certainty that “cool” adds value and bestows desirability but there is uncertainty about what “cool” means. Since “cool” is a cultural phenomenon, the purpose of this paper is to explore its meaning in the Indian context.

The data were obtained on an open-ended questionnaire followed by depth probes on a sample of young consumers. The obtained scripts were coded and classified into semantic categories based on the grounded theory.

The study found that cool is indicated by seven facets, including being oneself, living life to the fullest, sense of humor and socially networked, and calm disposition. Unlike Western notions, in India, cool is not being deviant and hedonistic. The cultural and religious imprints are palpable in what is construed as cool in India.

Transplanting the Western notions of cool for brand building is likely to be a risky proposition. It may not resonate with the inner cords of the Indian youth. The implication of this study is that it reveals possible ways in which cool can be incorporated in brand identity.

Cool is valued because it bestows distinction in subtle ways. Brands can gain traction among consumers by incorporating cool symbolism in their identity.

This study expands the understanding of cool in the context of an emerging market. This is one of the first studies to have probed the concept of “cool” in India.

Considering the growing prominence of millennials in the workforce, the current work explores the idea of cool employers as perceived, particularly by millennials.

Utilizing a mixed methods approach, the authors explore the polar concepts of cool and uncool potential employing organizations through a two-phase study that examined millennial's and nonmillennials’ perceptions of the components that constitute a cool or uncool organization to work.

The findings of the study indicate a difference between millennial and nonmillennial perceptions regarding the characteristics of a cool or uncool employing organization. Additionally, the authors discuss the dimensions of the cool and uncool organization concepts as perceived by millennials in the context of pertinent organizational theory.

Based upon the tenets of attraction–selection–attrition (ASA) theory and social identity theories, an organizational coolness concept is developed.

Web search is more and more moving into mobile contexts. However, screen size of mobile devices is limited and search engine result pages face a trade-off between offering informative snippets and optimal use of space. One factor clearly influencing this trade-off is snippet length. The purpose of this paper is to find out what snippet size to use in mobile web search.

For this purpose, an eye-tracking experiment was conducted showing participants search interfaces with snippets of one, three or five lines on a mobile device to analyze 17 dependent variables. In total, 31 participants took part in the study. Each of the participants solved informational and navigational tasks.

Results indicate a strong influence of page fold on scrolling behavior and attention distribution across search results. Regardless of query type, short snippets seem to provide too little information about the result, so that search performance and subjective measures are negatively affected. Long snippets of five lines lead to better performance than medium snippets for navigational queries, but to worse performance for informational queries.

Although space in mobile search is limited, this study shows that longer snippets improve usability and user experience. It further emphasizes that page fold plays a stronger role in mobile than in desktop search for attention distribution.

Marketers often select unique color names for products to heighten shopper interest. The purpose of this study is to use self-referencing as the foundation for assessing how a product color name that involves the self impacts product evaluation. This paper also investigates the salient element that might moderate consumers’ responses, in particular for product categories where color serves mainly as decoration and is of secondary importance.

Two between-subjects experiments examined how self-referencing mediates the influence of generic versus identity color names on product evaluation (Study 1) and also tested whether the effect of naming product colors in identity terms is limited to the scenario where cognitive load is low rather than high (Study 2).

The results of this study show that identity color names are more persuasive than generic color names. Self-referencing mediates the results, and the favorable effect of identity color names is diminished in the case of high cognitive load. Such evidence suggests that consumers might face impediments for self-referenced processing when factors exhaust their cognitive resources. The decreased elaboration results in less favorable evaluation.

This research enriches knowledge of how an element as modest as a creative product color name influences consumer evaluation, with suggestions for approaches to color naming.
