Abstract

Additive manufacturing (AM) technologies is used to create plastic and metal parts layer by layer. Although AM provides lots of potential and benefit such as manufacturability of highly complex parts, the technology is still rarely industrial established for end-used part production purposes. One limiting factor that affects its establishment is the insufficient availability of design rules for AM. Indeed, large numbers of case studies are known that exemplarily present AM design freedoms. In order to support a suitable design for AM, concrete and function independent design rules are required. The effectiveness of the design rule is not well known. This project will study the effectiveness of the design rules for FDM system. To study the effectiveness of the design rules, the design rules will be applied to an existing design of a blender jar. The finite element analysis (FEA) will be analyzed on both existing design and redesign to make a comparison. There are advantages of using design rules. However, it is found that there are also disadvantages by using design rules. The advantages are it gives high Von Mises Stress which it is good because it can overcome more load to start yield. Besides that the deformation is smaller due to its smaller displacement than old design. The disadvantage is it has smaller factor of safety than the old design due to its high Von Mises Stress. The new design also takes a shorter time and using smaller material length to build the prototype than the old design. By comparing the existing design and redesign, the design rules that suitable to used to make a FDM’s prototype will be known. However, due to many flaws found during the development, proper analyses have been suggested for future study improvements.
