Embedding stereolithography (eSLA) is an additive, hybrid process, which provides a flexible production of 3D components and the ability to integrate electrical and optical conductive structures and functional components within parts. However, the embedding of conductive circuits in stereolithography (SLA) parts assumes usage of process technologies, which enables their direct integration of conductive circuits during the layer-wise building process. In this context, a promising method for in-situ generation of conductive circuits is dispensing of conductive adhesive on the current surface of the SLA part and its subsequent sintering. In this paper, the laser sintering (λ = 355 nm) of conductive adhesive mainly consisting of silver nanoparticles is investigated. The work intends to evaluate the curing behavior of the conductive adhesive, the beam-matter-interactions and the thermal damage of the SLA substrate. The investigations revealed a fast and flexible laser sintering process for the generation of conductive circuits with sufficient electrical conductivity and sufficient current capacity load. In this context, a characterization of the conductive structures is done by measuring their electrical resistance and their potential current capacity load.

In this article I discuss some of the theoretical implications of adopting moral economy as an approach to analysing new forms of flexible production and work. Despite a growing interest in the anthropology of precarity and work, the linkages between political and moral economies have been relatively neglected. By discussing E.P. Thompson’s approach to moral economy as well as ways moral economy has been discussed in anthropology, the article argues it is a timely and encompassing approach for the study of flexible work and precarity, as well as compliance and resistance to inequality. A nexus of diverse moral frameworks of value converge at the production site and back home, contributing to the reproduction of precarity and capital under flexible forms of accumulation. The article suggests that moral economy may offer an encompassing approach to studying individual ideas and practices and their relation with collective moral frameworks and confinements and to exploring change and change potential. It draws from an ethnography based on long-term fieldwork in a privatized factory in Bulgaria, in the context of radical economic transformations and privatization projects. It scrutinizes solidarities, tensions and inequalities developed around the conveyor belt, with a particular focus on gender and employment status inequalities and their intertwinement with managerial and household practices.
