Control of geometrical parameters of a single layer at additive forming of products by FDM technology

Questions are considered about the accuracy of the formation of the surface layer by additive methods. The analysis of works is carried out on a research subject. High values of the error of forming (approximation) are revealed at forming of surfaces of a complex profile by additive methods. The spatial orientation of a single layer is proposed to reduce the error of forming products by additive methods . Mathematical dependences are proposed to determine the value of the parameters of a single directed layer on the results of experimental studies. (paper)
