Abstract
Purpose
Organizational incentives and structures play a crucial role in realizing explorative and exploitative innovations in firms. Existing studies have neglected the role of trade-off mechanisms between the two on innovation ambidexterity. This study aims to investigate these trade-off mechanisms and their position on innovation ambidexterity.
Design/methodology/approach
Given the limited theoretical understanding, the authors conducted a case study with a sample of two Chinese firms with abundant interview and secondary data.
Findings
The results show that firms can develop innovation ambidexterity at two levels, namely, the time and space levels, using incentive synergy as well as organizational structures. Furthermore, the authors explain the role of the trade-off between incentive synergy and organizational structure in promoting a balance between explorative and exploitative innovation.
Originality/value
The authors propose trade-off mechanisms between incentive synergy and organizational structure and explore how trade-off mechanisms can play a role in promoting a balance of explorative and exploitative innovation at both time and space levels.

Abstract
Purpose
The existing research rarely explains the role of dynamic capabilities in the creation of value co-creation behaviors. The purpose of this paper is to explore how dynamic capabilities play a role in avoiding value co-creation traps and generating new value co-creation behaviors.
Design/methodology/approach
This paper collects rich interview and archival data from two Chinese manufacturing companies to examine value co-creation in digital servitization by the case study.
Findings
The paper discovers the value co-creation traps that enterprises face in digital servitization and analyzes the important role of resource and technology integration capabilities in avoiding these traps. Also, the research explores how network capability affects the generation of new value co-creation behaviors.
Originality/value
This paper develops a framework for dynamic capabilities to avoid value co-creation traps and generate new value co-creation behaviors.

Abstract
Purpose
The purpose of this study is to find the best geometries among the cylindrical, enamel and honeycomb geometries based upon the mechanical properties (tensile test, compression test and shear test). Further this obtained geometry could be used to fabricate products like exoskeleton and its supporting members.
Design/methodology/approach
The present research focuses on the mechanical testing of cylindrical, enamel and honeycomb-shaped parts fabricated through multi-jet printing (MJP) process with a wall thickness of 0.26, 0.33, 0.4 and 0.66 mm. The polymer specimens (for tensile, compression and shear tests) were fabricated using a multi-jet fusion process. The experimental results were compared with the numerical modelling. Finally, the optimal geometry was obtained, and the influence of wall thicknesses on various mechanical properties (tensile, compression and shear) was studied.
Findings
In comparison to cylindrical, enamel structures the honeycomb structures required less time to fabricate and had lower tensile, compressive and shear strengths. The most efficient geometry for fully functional parts where tensile, compressive and shear forces are present during application – cylindrical geometry is preferred followed by enamel, and then honeycomb. It was found that as the wall thickness of various geometries was increased, their ability to withstand tensile, compressive and shear loads also enhanced. The enamel shape structure exhibits greater strain energy storage capacity than other shape structures for compressive loads, and the strength to resist the compressive load will be lower. In the case of cylindrical geometries for tensile loading, the resisting area toward the loading will be higher in comparison to honeycomb- and enamel-based structures. At the same time, the ability to store the stain energy is less. The results of the tensile, compression and shear load finite element analysis using ANSYS are in agreement with those of the experiments.
Originality/value
From the insight of literature review, it is found that a wide range of work is done on fused deposition modeling (FDM) process. But in comparison to FDM, the MJP provide the better dimensional accuracy and surface properties (Lee et al., 2020). Therefore, it is observed that past research works not incorporated the effect of wall thickness of the embedded geometries on mechanical properties of the part fabricated on MJP (Gibson, n.d.). Hence, in this work, effect of wall thickness on tensile, compression and shear strength is considered as the main factor for the honeycomb, enamel and cylindrical geometries.

Abstract
Purpose
The current investigation aims at observing the influence of the cooling channel on the thermal and residual stress behavior of the selective laser melting (SLM)316L uni-layer thermo-mechanical model.
Design/methodology/approach
On a thermo-mechanical model with a cooling channel, the effect of scanning direction, parallel and perpendicular and scan spacing was simulated. The effect of underlying solid and powder bases was evaluated on residual stress profile and thermal variables at various locations.
Findings
The high heat dissipation of solid base due to high cooling rates and steep thermal gradients can reciprocate with smaller melt pool temperature and melt pool size. Given the same scan spacing, residual stresses were found lower when laser scanning was perpendicular to the cooling channel. Moreover, large scan spacing was found to increase residual stresses.
Originality/value
Cooling channels are increasingly being used in additive manufacturing; however, their effect on the residual stress behavior of the SLM component is not extensively studied. This research can serve as a foundation for further inquiries into the impact of base material design such as cooling channels on manufactured components using SLM.
