During my 6 months internship I worked in the R&D sector of the Airbond company for the designing of splicers for composite materials used in aerospace. My task were to turn a product idea into a functioning prototype. To do so I worked mainly with Solidworks software for the designing, PLC for the electronics part of the design and 3D printing for prototyping. I used FDM 3D printers as well as the advanced HP Jet Fusion 4200 3D Printer. I participate in trainings, prototype testing and brainstorming sessions of the company. I created a tutorial of my best practices to give my feedback on how the company can perform better in order to result in profit and time efficiency methods. The projects I participated would be introduced in a million pounds market.
