Chuck Hull is the father of 3D printing. It was invented in 1986. I found a source about the reason behind the creation.
At the time, he was working for a company that used UV light to put thin layers of plastic veneers on tabletops and furniture. Like others within the industry, he was frustrated that the production of small plastic parts for prototyping new product designs could take up to two months.
He had an idea that if he could place thousands of thin layers of plastic on top of each other and then etch their shape using light, he would be able to form three dimensional objects. After a year of tinkering with ideas in a backroom lab after hours, he developed a system where light was shone into a vat of photopolymer – a material which changes from liquid to plastic-like solid when light shines on it – and traces the shape of one level of the object.
He had a clear idea and goal when he wanted to invent 3D printing. It is similar to personal project. For example, I came up with my idea of 3D printing the phone case, which then I research and accomplish it. Innovation is part of the reason why Chuck Hull could invent 3D printing. In my opinion, it is important to not be afraid by the obstacles we face and never give up on making our ideas come true. For example, Chuck Hull must’ve spent a lot of effort on inventing, perhaps even failing. He finally achieved it because he worked hard.
