So I’ve been pretty quietly been working on this project with my two good friends @willy_ckh and Henry. This is a sword design from @warcraft back from the WotLK Naxxaramus raid called “Life and Death”. For one of recent engineering courses in undergrad, Henry and I were tasked on performing finite element analysis (FEA) on a project of our choosing. FEA is typically used for boring but useful stuff like “will this bridge fall” before you spend the $$$ in time and resources, lol. Since 3D printing is a big thing in the cosplay world and it feels really bad when you build something cool only for it to break shortly after, I thought this was a creative way to use FEA and kill two birds with one stone. We built the said model based on in-game references, and tested (1) how sturdy said model was using popular 3D printing materials, namely ABS, PET, and PLA, and (2) which would be the best material to 3D print with for robustness. It turned out PET>>PLA>>ABS. We were going to 3D print with PET, but I goofed up and learned PETG is the common 3D printing plastic filament and PETG is significantly worse than PET as in terms of material properties and slightly below PLA as a sturdy material. So we opted for PLA instead. Swiping right you can see half the sword so far printed in black PLA. The last video is the LED strip we’ll be using to illuminate the fins and belly of the sword :) All the model was made by Henry, and 3D parts are printed by @willy_ckh . I just did the code, power, and lighting stuff :>) . . . . #3dprinting #worldofwarcraft #worldofwarcraftcosplay #cosplayprogress #cosplaypropmaking #cosplayprop #cosplaylights #engineeringstudent #finiteelementanalysis #microcontrollers #embeddedsystems #embeddedelectronics #led #engineeringproblems #sfumechatronics #mechatronicsengineering
