The researches used this kind of research design to test past theories about the efficiency‚ effectivity and usefulness of the laser light activated alarm. Determination of sample size The researchers had a total of 20 respondents‚ consisting of 4 respondents from different sections which are all in

case of lamination systems‚ thin layers are cut to shape and joined together. Selective laser sintering (SLS) Selective laser sintering (SLS) is an additive manufacturing technique that uses a high power laser (for example‚ a carbon dioxide laser) to fuse small particles of plastic‚ metal (Direct Metal Laser Sintering)‚ ceramic‚ or glass powders into a mass that has a desired 3-dimensional shape. The laser selectively fuses powdered material by scanning cross-sections generated from a 3-D digital

INTEGRATED PRODUCT DEVELOPMENT AND STRATEGIES ASSIGNMENT – I S.SATISH BABU 11MD34 RAPID PROTOTYPING Rapid prototyping is the automatic construction of physical objects using additive manufacturing technology. The use of additive manufacturing for rapid prototyping takes virtual designs from computer aided design (CAD) or animation modeling software‚ transforms them into thin‚ virtual‚ horizontal cross-sections and then creates successive layers until the model is complete. It is a

with other people. As a result‚ it enables other people to evaluate your innovation or learn from it. The David Laser Scanner is a 3D scanning software (David laser scanner‚ 3) made by a German scientist. A webcam is attached to the computer. White screens must cover the object. Than a small laser blue or green laser light is shone up and down a desired object. The David laser scanner software sends back data to the computer and visualizes the object. This can be exported to a variety of files

gyroscopes were patented for use on ships. Around 1916‚ the gyroscope found use in aircraft where it is still commonly used today. Throughout the 20th century improvements were made on the spinning gyroscope. In the 1960s‚ optical gyroscopes using lasers were first introduced and soon found commercial success in aeronautics and military applications. In the last ten to fifteen years‚ MEMS gyroscopes have been introduced and advancements have been made to create mass-produced successful products with

materials and utilize a light laser to harden the resin in layers. The most common process is deposition. This process uses plastic materials to form layers and create a shape of the object. Inkjet has superior materials to ink and binder to fix the layers. Deposition is the most common process which forces plastics in filament form through a heated extruder to create layers. 3D printing processes: Stereo lithography Digital Light processing Laser Sintering/Laser Melting Extrusion/Fused

or micrometres. Typical layer thickness is around 100 micrometres (0.1 mm)‚ although some machines such as the Objet Connex series and 3D Systems’ ProJet series can print layers as thin as 16 micrometres.[4] X-Y resolution is comparable to that of laser printers. The particles (3D dots) are around 50 to 100 micrometres (0.05–0.1 mm) in diameter. Construction of a model with contemporary methods can take anywhere from several hours to several days‚ depending on the method used and the size and complexity
