This chapter explores transformation of a virtually produced gear to a physical product using rapid prototyping technique. The same can be segregated into two parts. The first being selection of the best possible rapid prototyping technique using dynamic mechanical analysis and the next was optimization of the process parameters of the selected rapid prototyping technique considering tensile strength as the criteria. The results indicated that fused deposition modeling process provides the best solution amongst the techniques studied. Moreover, as orientation of the product in rapid prototyping techniques plays an important role in providing the strength and also accuracy of the product profile, from results it was also ascertained that strength and profile accuracy of the product was optimized with horizontal position.

Rapid Prototyping (RP) technology makes it possible for manufactories or Institutes conceiving the product directly from its CAD models without any tooling or human interference. This study explored the modeling process of toy aircraft based on Pro/Engineering through a component drawing, introduced the basic setups of Fused Deposition Modeling (FDM) process by using a rapid prototyping machine. Summarized the advantages and shortages of FDM,point out that the method using CAD&RP technology may be useful in designing a new product , it promising development in making of complex component or mould, and the need of colorful materials used in RP.

Development Area

In this paper, a comparison between CNC manufacturing and Rapid Prototyping technology (FDM – Fused Deposition Modeling process), applied for a cam fabrication, is presented. In the products development area, a substantial support is offered by models, as intermediate between product configuration and technology design. The CAD/CAM/CNC technology is a widely used technique for creating prototypes, as well as production parts, using a subtractive type material-removal procedure from a semi-manufactured article. The rapid prototyping (RP) technologies are additive processes, where the part is built up layer by layer until done, directly from the 3D CAD model, within the precision limits of the chosen process. Similarities and differences between these two coexisting computer driven prototyping processes, the subtractive CNC 3 – axes milled part production and the additive RP/ FDM technique, are pointed out for a disk cam manufacturing as sample part.

Part Orientation

The article focused on the influence of part orientation on the surface roughness of cuboid parts during the process of fabricating by FDM technology. The components, in this case, is simple cuboid part with the dimensions 15 mm x 15mm x 30 mm. A geometrical model is defined that considers the shape of the material filaments after deposition, to define a theoretical roughness profile, for a certain print orientation angle. Five different print orientations in the X-axis of the cuboid part were set: 0°, 30°, 45°, 60°, and 90°. According to previous research in the field of FDM technology by the author, the internal structure (infill) was set at the value of 70%. The method of 3D printing was the Fused Deposition Modeling (FDM) and the material used in this research was thermoplastic ABS (Acrylonitrile butadiene styrene). For each setting, there were five specimens (twenty five prints in total). Prints were fabricated on a Zortrax M200 3D printer. After the 3D printing, the surface “A” was investigated by portable surface roughness tester Mitutoyo SJ-210. Surface roughness in the article is shown in the form of graphs (Fig.7). Results show increase in part roughness with increasing degree of part orientation. When the direction of applied layers on the measured surface was horizontal, significant improvement in surface roughness was observed. Findings in this paper can be taken into consideration when designing parts, as they can contribute in achieving lower surface roughness values.

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
