Haier realized a 3D printed fully functional air conditioner that was presented at the Appliance and Electronics World Expo held in Shanghai. This innovative appliance will allow future buyers to completely customize the design and function of the 3D printed air conditioner according to how they want it to be. “Each piece of the unit is produced on demand, seamlessly linking users’ requirements and actual manufacturing. Building the object layer by layer, 3D printing allows unprecedented user customization. Every user can parametrically adjust their own model, depending on his/her taste and requirements. Each model is a unique piece”, the company said in a official note. Users can also customize the LCD screen used for displaying the temperature and status.
