The level of integration between the marketing and research and development (R&D) functions may be gauged by degree of communication, information sharing, and collaboration between the functions during the new product development process. This article examines how a firm's strategic choice regarding market orientation may influence the relationship between marketing and R&D personnel, and how this relationship may affect organizational success. Under examination are both the responsive form of market orientation, in which a firm focuses on immediate customer needs and tends to be market driven, and the proactive form, in which the firm focuses on future market needs and tends to be invention driven. It is theorized that responsive market orientation will be more positively related to marketing‐R&D integration due to the market‐driven nature of the orientation. Conversely, it is theorized proactive market orientation will be more positively related to organizational success than responsive market orientation due to the innovation‐driven nature of the orientation. The study was implemented via a Web‐based survey and data analysis was performed using structural equation modeling techniques. The results of this study provide empirical evidence that both proactive and responsive market orientation exhibit a positive relationship with marketing–R&D integration, indicating that both forms of market orientation may lead to closer collaboration between the marketing and R&D functions. Despite the assumption that a proactive orientation is driven by innovation and technology in which R&D may play a more significant role, there is evidence that a high degree of synergy is developed between the groups when the focus is on future market needs. A market‐driven responsive orientation by necessity requires high integration between departments to commercialize products in a timely manner to meet current market needs. Proactive market orientation exhibits a positive relationship with market performance, whereas responsive market orientation does not. The result may show evidence of the “new product paradox," whereby developing products to address immediate market needs may result in lower market performance because the new products may be replacements for obsolete offerings or are actually cannibalizing sales of existing products.

Abstract:A useful and increasingly common additive manufacturing (AM) process is the selective laser melting (SLM) or direct metal laser sintering (DMLS) process. SLM/DMLS can produce full-density metal parts from difficult materials, but it tends to suffer from severe residual stresses introduced during processing. This limits the usefulness and applicability of the process, particularly in the fabrication of parts with delicate overhanging and protruding features. The purpose of this study was to examine the current insight and progress made toward understanding and eliminating the problem in overhanging and protruding structures. To accomplish this, a survey of the literature was undertaken, focusing on process modeling (general, heat transfer, stress and distortion and material models), direct process control (input and environmental control, hardware-in-the-loop monitoring, parameter optimization and post-processing), experiment development (methods for evaluation, optical and mechanical process monitoring, imaging and design-of-experiments), support structure optimization and overhang feature design; approximately 143 published works were examined. The major findings of this study were that a small minority of the literature on SLM/DMLS deals explicitly with the overhanging stress problem, but some fundamental work has been done on the problem. Implications, needs and potential future research directions are discussed in-depth in light of the present review.
