“…Following the research initiative of Lipson and Pollack (2000) on 3D printing autonomous (in terms of power, behaviour and even of design and fabrication) robotic systems based on structure and control building blocks, Kheifetz (2018) considers that it is necessary to use 3D machines to produce objects and that self-organization processes cannot meet this objective. The previous paragraphs seem to prove him right because it seems difficult, on reading the bibliography, to master precisely a shape that meets a prior instruction.…”

Additive manufacturing is based on a deterministic principle of spatially localized material transformation. By using spatial energy resolution modes, it is thus possible to produce an object that meets a set of specifications in a step-bystep manner. This paper attempts to take the opposite view by examining whether it is interesting to use knowledge on "morphogenesis" (cf. Alan Turing) and other conceptual ideas of spontaneous self-organization to achieve a desired shape. This new and more systemic form of 3D/4D printing enables the self-assembly and establishment of elements (voxels) in various environments through the use of programmable or smart matter. The necessary convergence of interacting elements requires a related decisive activity, however, to the sign of unknown, indecision, complexity, unpredictable bifurcations, in short of scientific promise that cannot be robustly kept. Beyond this frame of generalized non-decidability-a form of abandonment of self-organization paradigm in favour of deterministic doctrines-, there are paths to partial success where desired spatial transformations can be created through (mastered?) disorder. The paper presents the conceptual bases of 3D selforganization with some illustrative examples. The objective is to highlight the interests of this disruptive vision with its realistic limits.

The article presents the results of studies of the surfaces of parts processed by the contactless method of laser polishing. The results of technological surface treatment using a laser technological complex based on an ytterbium fibre laser with a power of 5 kW are presented. The results of studies of the surface roughness of the samples after laser treatment, including the non-uniform character due to the redistribution of the liquid metal melt over the surface, are shown. Requirements for metrological support of additive technology have been developed using the example of the process of laser remelting in order to improve quality and further automation.

“…The boundary conditions in the layer-by-layer formation of structures are recommended to determine by the size and position of the barriers describing the conditional interface of the layers [19,20]. During hardening and softening, the barriers are located on opposite sides of the coordinate axis (Fig.…”

Technological heredity of operational properties in the processes of manufacturing, operation and restoration of machine parts is proposed to describe by the graph reflecting the coefficients of transmission and mutual influence of physical, mechanical and geometric parameters. The technological control methods of the heredity of operational properties of parts are considered, including: measuring parameters of the most critical parts; determining technological heredity mechanisms on the basis of transfer coefficients and mutual influence of operational properties; analyzing technological barriers during intensive effects of energy flows, developing measures for controlling technological processes.
