Abstract

Purpose

The aim of this paper is to examine the effects of light controlling system that combined high refractive particles (n-TiO2 [titanium dioxide – TiO2]) and tartrazine lake dye (TL dye) on thickness, flexural strength, flexural modulus and surface details of the 3D-printed resin.

Design/methodology/approach

Influences of different concentrations of n-TiO2 and TL dye in light-cured resin formulations for 3D printing (3DP) application were evaluated, including curing thickness, flexural strength and surface details under scanning electron microscopy.

Findings

The polymerization thickness of samples containing both n-TiO2 and TL dye was lower compared to samples with TL dye solely. Samples containing more n-TiO2 and more TL dye exhibited lower flexural strength and modulus. Ramp models showed that for samples containing 1 per cent TL dye, when their n-TiO2 content increased from 1 to 5 per cent, surface laminate structures became sharper. However, when the TL dye content doubled to 2 per cent, the surface laminate structures were indefinite compared to 1 per cent TL dye-containing counterparts.

Originality value

In visible-light 3DP, light controlling system in cooperate dye with high refractive particles provides better energy distribution and scattering control. High refractive particles, dyes and light exposure time had influenced the surface resolution and mechanical properties of the 3DP products.

Abstract

Purpose

To deepen our understanding about the development of turnover intention, the purpose of this paper is to develop a model that explains how ethical climate influences turnover intention based on the ethical climate theory and social identity theory.

Design/methodology/approach

The hypotheses of this study were statistically tested using a survey of working professionals from Taiwan’s high-tech industry. Of the 400 questionnaires distributed to the working professionals from five large high-tech firms in a well-known science park in Northern Taiwan, 352 usable questionnaires were returned for a questionnaire response rate of 88 percent.

Findings

The test results of this study first show that all three dimensions of ethical climate (i.e. instrumental, benevolent, and principled) are indirectly related to turnover intention via the mediation of firm attractiveness. Moreover, instrumental and benevolent climate directly relate to turnover intention, whereas benevolent climate negatively moderates the relationship between principled climate and firm attractiveness.

Originality/value

This study finds that benevolent climate plays a dual role as an antecedent and a moderator in the formation of turnover intention, complementing prior studies that merely concentrate on the single role of benevolent climate as either an antecedent or a moderator. The effect of principled climate on organizational identification complements the theoretical discussion by Victor and Cullen (1987) about deontology in which an ethical workplace climate (such as legitimacy) drives employees to invest in identity attachments to the organization and influences their future career decision (e.g. turnover).
