Product design is the process of improving existing products or creating new products for the market. It involves the generation and development of ideas through a systematic process that leads to the creation of innovative products. The process involves research, idea generation, iteration and testing leading to production. A product designer needs to have both creative and technical abilities, combining art, science, and technology to create new products that people can use. Expertise in using hand tools and digital tools such as 3D modelling and 3D printing helps in bringing ideas to life.
