- Аннотация: There are made box of machines and mechanism, parts of the skeleton, weapons by 3d printing technology. Parameters of the printing technology are mainly defined on a subjective choice of the operator. Research of the effect of the print settings on the physical and mechanical properties of the printed object was done at first. There were done experiments of stretching specimens made from ABS- plastic by 3D printing technology. Fig. 1 shows the elastic modulus vs. of the temperature manufactured. The process of filling a significant influence on the behaviors of the specimen. Research of the density of the specimens were done. We can conclude that the specimens with a transverse filling (2) have substantially less void volume of pouring than the specimens with longitudinal filling (1). Fig. 2 shows photographs of a rupture places vs. different manufactured temperatures (205˚C, 220˚C, 240˚C). It can be seen that denseness of the specimen is increased with increasing temperature manufactured of the specimen and the shape of the filament is changed. There was found optimum temperature range (220˚C) of melting, found pores of regular (1, Fig. 2) and irregular nature, found that specimens with transverse filling have less pores than the longitudinal ones. Irregularity strength between specimens with longitudinal and transverse directions of the filling can be greatly degraded if you use enlarged temperature printing and simultaneously forced air cooling. Printing accuracy is increased.
