Week 1

Die casting is a type of metal casting that can generate a large number of castings with excellent surface quality in a short time by pressing molten metal into metal molds at high temperature, speed, and pressure. A method is proposed to improve the accuracy of die casting by correcting metal mold. 3D scanning is adopted to measure the shape of cast aluminum. The 3D scan data of cast aluminum includes information about deformation in die casting; consequently, deformation and correction values can be estimated by comparing scan data with product CAD data. In general, 3D scanning technology is utilized for inspection of mechanical product. Thickness and clearance are basic parameters in product design. To assist the machine designer, some CAD systems provide part thickness visualization functions for wall thickness analysis methods for optimal design of casting parts, SOLIDWORKS and Dassault Systemes. A method is proposed for visualizing the thickness and clearance of three-dimensional (3D) objects in a polyhedral representation. The proposed method employs the distance field of an object for the visualization. The 3D distance field of the object is a uniform cell decomposition of the space where at each cubic cell (voxel) in the space, the distance from the center of the voxel to the closest point on the object surface is recorded. To develop a suitable method for designing fiber composite materials, two points must be considered. Since fibers are oriented in the matrix, products made of fiber materials have anisotropic mechanical properties. Therefore, designers should take into account the underlying directions of fiber in the final product. This point concerns the ability of materials to assume thick and complex shapes. To prepare a thick fiber material product, several planar woven fiber laminates are accumulated or 3D woven fiber materials are used. Woven materials have advantages in terms of manufacturing costs and the stiffness.

Week 1

2 Chosen Sketches: 

Selected Concept

The concept was selected from the image above, which was built by Sou Fujimoto and has the aspect of contrast and constructed. It has the aspect of contrast because there is a big difference in the size of the 2 beams and the other components of the structure. It also has the aspect of constructed because the structure has the beams, which has the similar look as a normal building, which has pillars and steel beams.

The basic of the structure is taken from the building above, which is Frank Lloyd Wright's building, which is called Falling Water. The structure has the aspect of complex and adaptable. The aspect complex comes from the irregular looking like planks which stick out from every sides of the building and the aspect adaptable comes from the original building, which the building itself is located in a forest.

Final Model:  

The structure is positioned as such because it is located in a two way, so that the two front sides are more emphasized and so that the people can have a better look of the contrast between the three types of shadings that are located on every sides of the structures.
