The purpose of this research is to study the accuracy of RP FDM Process. This research involves varying two parameters in building up the prototype which is the buildup angle and the sparse for each layer (volume of parts). The varying parameters were used in the FDM process for three types of specimen (profiles) which is the Cube, Cylinder and Pyramid. The varying parameters are the build up angle of 300, 650 and 900 and for the types of sparse, there are three types of sparse used which is Low Density (LD), High Density (HD) and Solid Type. The results of the dimensional accuracy are analyzed by calculating the percentage of difference of the dimensional measurement for the specimen and the actual dimension of it. The lesser difference, the better the dimensional accuracy. The conclusion of this study is the less complicated specimen shape for the FDM process, the more accurate of the dimensional accuracy with the optimum build up angle of 300 or less and the optimum type of sparse of Low Density Type (LD).

Deposition Modeling

The article focuses on the research of selected thermoplastic materials processed by the Fused Deposition Modeling (FDM) additive manufacturing method and dimensional accuracy of parts in particular. The selected thermoplastic materials were ABS, PLA and HIPS. The digital model of the object (upper teeth) was obtained by the intraoral 3D scanner of 3Shape TRIOS used in dentistry. Based on the 3D (Three Dimensional) scanned digital model, the manufacturing of the upper teeth was performed on the Zortrax M200 FDM 3D printer. Parameters of the manufactured parts were as follows: Layer thickness 0.09 mm, infill 20% and model orientation 0°. The manufactured parts were digitized by the GOM ATOS Triple Scan optical 3D scanner with the measuring volume of MV 170. The dimensional accuracy of the parts was evaluated in the GOM Inspect software.

Manufacturing Methods

With increasing usage of additive manufacturing methods for mechanical parts the need for precise and reliable simulations of the manufacturing process increases as well. In this paper various com- putations suited for simulating the fused deposition modeling process are considered in two dimensions. In fused deposition modeling a molten polymer is laid down on a prescribed path before the cooling of the melt begins. The occuring flows are treated as multiphase flows. To model the deposition of the filament, methods of computational fluid dynamics are used in ANSYS-Fluent, namely the volume of fluid method (VOF). Different numerical experiments are simulated
