A possibility to use vector fonts in the integrating frame of the "Virtual 3D-printer" software package is shown. It provides application of the text, symbols or a logotype of the company on the structures and items produced in the process of additive production using the method of layer-by-layer laser sintering of a metal powder mixture. SVG-format of computer scalable vector fonts is considered. Its brief description is provided in the language of commands of 2D Scalable Vector Graphics. An approach is proposed to produce the coordinates of the points that lie on the boundary of delineating the symbol of the vector font. A syntactical SVG-analyzer (a parcer of glyphs of the font symbols) and the rasterization library of quadratic and cubic Bezier curves realized for these purposes are described. There is an example of using developed programs to form a 3D scene from the line of symbols produced with a vector font. There are photos of the 3D text produced in the process of additive production. Keywords: SVG-format of vector fonts, Bezier curves, a parcer of glyphs of symbols, rasterization library, additive production.
