Abstract
Purpose
This paper aims to study the different infill, printing direction against sliding direction and various load condition for the friction and wear characteristics of polylactic acid (PLA) under reciprocating sliding condition.
Design/methodology/approach
The tests were performed by applying the load of 1, 5, 15 and 10 N with sliding oscillation frequency of 10 Hz for the duration of 10 min at room temperature.
Findings
The results show that the friction and wear properties of PLA specimen change with a different infill density of printed parts. The oscillation frequency is 10 Hz and the infill density of plate is 50 per cent that shows the best friction and wear properties.
Originality/value
The potential of this research work is to investigate the tribological characteristics of three-dimensional printing parts with different infill percentage to provide a reference for any parts in contact with each other to improve friction and wear performance. There will be many opportunities exist for further research and the advancement of three-dimensional printing in the field of tribology.

Abstract
Purpose
The purpose of this paper is to deepen the understanding of the predictors and outcomes of knowledge sharing in a franchise system. An integrative framework is proposed to examine the influence of franchisee self-leadership on knowledge sharing and its subsequent influence on franchisee satisfaction and compliance.
Design/methodology/approach
On the basis of a survey of 111 franchisees of two leading bakery franchise brands in Korea, this study confirmed data validity and tested hypotheses by adopting partial least square–structural equation modeling.
Findings
Regarding the predictor of knowledge sharing, this research found that franchisee self-leadership has a positive effect on knowledge sharing. As outcomes, it found that active knowledge sharing has a positive effect on franchisee satisfaction and compliance. This study also shows that knowledge sharing mediates the relationship between self-leadership and franchisee satisfaction.
Practical implications
This research advises franchisors to actively develop programs and communication channels for knowledge sharing with franchisees to induce high levels of compliance and satisfaction. Furthermore, as selecting potential franchisees is key to the success of franchising, this research highlights the significance of self-leadership as a crucial personal trait of franchisees.
Originality/value
Despite the rapidly growing academic interest in franchise knowledge sharing, sparse theoretical approaches and empirical evidence are available. To address these limitations, this research presents an integrative model and empirical evidence.
