A full factorial 23 matrix was designed to study the bending strength, permeability and hoop-stress of investment moulds. A novel method of ethyl-silicate hydrolysis; two-step hydrolysis, was used. The results indicate that the bending strength is directly proportional to the quantity of filler material in the slurry. Grain size of stucco material appears to exert the least effect on bending and hoop strength, whereas permeability increases slightly when coarser grain is used.

Abstract-Engineering drawing is a universal language of anEngineer which allows engineers to create designs, represent them on a drawing sheet, calculate distances, and create a blue print before manufacturing. All engineering students undergo a complete course on engineering drawing where orthographic projections are taught. In orthographic projections, the students are asked to imagine a 3D situation and make the 2D orthographic projection drawing. This part of 3D imagination and converting it into orthographic projection is difficult for students to mentally visualize. To ease the student's imagination, An Augmented Reality solution is developed jointly by BMSCE and Bosch (RBEI), Bangalore. A powerful 3D graphics association has been developed which forms the primary source of developing the drawing as orthographic projections that is viewable in 3D in real world.The current article focuses on the importance of AR in engineering education and its benefits.

A polymer composite material is a two phase material made up of a matrix and reinforcement. The constituents must be considered appropriate proportions for the desired properties in the final laminate prepared. Compared to other manufacturing methods of making polymer matrix composites, Resin transfer molding (RTM) allows better control over complex geometries and parts with larger diversities. The mold design becomes an important aspect of the process in RTM as the process is automated and quality of the part made depends on the design of the system. This work focuses on product design approach to designing and fabrication of mold for manufacturing fiber reinforced plastic laminates which is free from vacuum leakage. Although the RTM method is an old method, not much of the literature on optimum designing of the system is available. Product design approach is used in this work as it helps problem solving in a systematic way.
