3D printing or additive manufacturing is a parts manufacturing process using a digital model can be drawn using suitable computer aided design (CAD) They can be created using 3D printing products of almost any shape. This article presents research concerning the deviation in shape of the parts obtained by additive manufacturing (3D printing). The digital model was made with Catia V5 and was imported by the 3D machine software to obtain the prototyping codes for nine specimens. The specimens were made according to a Taguchi L9 plan. On the basis of the code obtained with the printer software, the parts have been prototyped, using the Z-ULTRAT material with a ZORTRAX M200 printer. The input data that were varied are: layer thickness, infill and orientation. For each part obtained by 3D printing were measured: circularity, flatness and dimensional accuracy. All parts were measured and a database was created and following the regression analysis performed with the Minitab19 software was establish the influence of the parameters on the deviations and dimensional accuracy.
