The analysis of the current state of 3d industry and prospects for its future. In the work, calculations were made and graphs of dependence were obtained, which influence the work of the auger and the installation itself. A new method of printing parts with polymer granules is described and the principle of operation of the equipment used is described. The picture of the working installation with the main components and the method of its attachment on a 3D printer is presented.
The results of research of concentration distribution of plasticizer on the radius of cellulose nitrate granules are presented in the article. A smooth handing down profile of this distribution is confirmed for the cellulose nitrate granules obtained with the varnish method on the example of camphor and dibutyl phthalate. The mathematical description of this distribution, the basic parameter of which is determined with the plasticizer content in granules, is offered.
