Elizabeth Montalbano. (2019, January 25). Breakthrough 3D Printed Materials Make Strong, Lightweight Structures. Retrieved from https://www.designnews.com/materials-assembly/breakthrough-3d-printed-materials-make-strong-lightweight-structures/133147783059994 This article focuses on a stronger and lightweight 3D printed material through a new interior structure design. It provides the benefits of the new plate-lattice structure as compared to the truss-lattices structure which has been around for a long time. The most well-known truss-lattice structure would be the Eiffel Tower. For truss-lattices structure, whenever a force is being applied, one out of three of the structs withstands the incoming force, the two others being idle. Whereas, when it comes to the plate-lattice structure, the other two structs instead of being idle would provide stability to the structure. This new structure increases the efficiency of the entire structure, thereby improving overall strength and stif...

An Affordable Carbon-Fiber Bicycle For The Masses Team name: Lapis Bikes Lecturer: Professor Brad Blackstone Module: MEC1281 Date: Group Members: Matriculation No: Zulhusni (Leader) 1901740 Hilmi 1901699 Yong Wei 1901761 Yong Xun 1901704 Proposal Contents Executive Summary Introduction Background Problem Statement Purpose Statement Proposed modification Benefits Evaluation Limitations Methodology Concluding Statement References Appendix: A  Doi.  Executive Summary Background Today, the cost of a carbon fibre bicycle ranges from $2000 to upwards of $10,000. A majority of the costs incurred is due to the research and development required to develop these bicycles for the market.  According to Becker (2018), the cost of a mold of a carbon fibre bicycle “costs between $60,000 and $100,000 depending on a number of variables”. The high costs are due to a number of factors. Firs...
