“…The preparation includes the following stages in printing using FDM technology in general: the separation occurs of a three-dimensional digital model, as a rule, in STL format, which is a list of coordinates of the vertices of triangular faces (facets) forming a surface into many curvilinear layers; the task is to select the trajectory of the extruder relative to the part; finding is carried out by areas of filling with material in accordance with the shape of the part [16][17][18][19][20][21][22]. The layer is applied one by one until the object is completely built.…”

Abstract. This paper presents a solution to the problem of filling the internal structure of the workpiece with curve layer in 3D printing. A generalized model of filling the internal structure of workpiece with curve layer is designed. The results are presented for solving the problem on the example of curved layers of a conical shape with filling along a helical line. The research results can be in demand in the development of algorithms and software for technological equipment. They allow to ensure the formation of the internal structure of products in curved layers during 3D printing.

Purpose of research. Accuracy improving of product forming additive methods is described in the paper. Analysis is carried out; new device design for product forming by additive methods is done on the basis of parallel-serial structure mechanisms. This device design provides rigidity of technological system, increased accuracy of final element positioning of forming system, thus expanding technological capabilities of additive formation.Methods. Formation of parts surfaces by additive methods is characterized by high formation error size (approximation). It is necessary to ensure orientation of the surface in order to reduce the size at which normal will coincide with the axis of forming system final link at formed surface point. The paper presents results of the analysis aimed at existing structures installation of additive forming devices on the basis of parallel-serial structure mechanisms ensuring high accuracy of final link positioning of forming system.Results. Device design for additive product forming according to 3DMP technology - technology of additive forming with electric arc in protective gases, application of which provides high accuracy of final link positioning of forming system, excludes possibility of rigid consumable material jamming in the form of wire due to design of supply mechanism, which is rigidly fixed on the device base for additive forming.Conclusion. Application of developed device design will make it possible to eliminate disadvantages of existing devices for additive forming, to ensure accuracy of final link positioning of forming system for additive equipment, to exclude possibility of rigid consumable material jamming, thus expanding application field of additive technologies.

“…The questions [13] of the formation of errors during machining were investigated in the work. In it, the processing error was considered as a result of the action of the corresponding components: It should be noted that the shaping of parts by the method of welding with an electric arc in a protective gas, like most methods of additive shaping, is characterized by high values of the static component of the processing error, which, in general form, can be represented in the form of the equation [14,15]: There were published works [9][10][11][12], in which, as a result of theoretical studies, it was indicated that one of the measures to reduce the error in the shape of additive methods of shaping can be a change in the spatial orientation of the deposited layers. However, they do not represent information from experimental studies that confirm or refute the results obtained.…”

The paper presents the results of a study of the process of additive surface shaping by an electric arc in a protective gas. An analysis was made of the errors in the shape of surfaces obtained with different filling of layers. It has been experimentally confirmed that such process parameters as the orientation of the layers, the coefficient of their overlap are significant and affect the numerical value of the error in the shape of the resulting surface. In this connection, they should be taken into account when designing algorithms for dividing into layers and filling them with additive shaping by an electric arc in a protective gas.
