The most important areas of the industry, need products with short development stages. Additive manufacturing (AM) techniques, as Fused Deposition Modelling (FDM), are an integrated solution to the overall conception and product development cycles; the same competition is based on the development of new products with technological features, design and functional solutions in the shortest time. In this paper are discussed different process parameters for fused deposition modelling that affects the parts quality by using a low-cost 3D printer machine in order to produce an industrial product. The process parameters taken into the analysis, resulted effective in improving final parts quality.

Recently, development in the 3D technology is becoming more evident. The diffusion of the acquisition systems is helped from the rapid evaluation of the information technology and Mechatronics, permitting low-cost system by using off-the-shelf hardware (webcam, projectors, etc.) for 3D scanning. This paper is focused on the development, implementation and testing of an automated low cost motorized active 3D structured light scanning system (SLS). The scanner is based on the software platform of the DAVID Laser Scanner Vision Systems GmbH’s. Advanced of basic technologies for comparing the scanned data, will show the differences in performance of the 3D data acquisition with a test to reference approach with a commercial scanning system.

The aim of this research it was the installation of an intake sea water GRP (glass-reinforced plastic) structure in Vlore Bay. A detailed study about the extreme wave condition offshore was carried out by the SWAN (Simulating Waves Nearshore) model. Then the mechanical structure stability calculation was performed with AxisVM8, a finite element modeler & solver. Conservative hypothesis were taken, such as to use the max static pressure value as per energy balance calculation on the sea waves. The program Fluid Flow was used to model the pipe line end with pipe chimney connections. The scope of the calculation was primarily to balance fluid flows in each chimney in order to match the range of 0, 2 – 0, 25 m/s velocity at each chimney entrance. The result of the mechanical and hydraulically stability verification for the sea water intake structure take in consideration it was positive and this structure was installed successfully.
