3D printed jet engine fuel nozzles are used in aerospace applications. These nozzles are made from a single piece of metal,reducing weight and increasing durability. 3D printing also enables more complex and efficient designs,improving fuel consumption and reducing emissions.

3D printing creates patient-specific surgical models from medical imaging data.These models can help surgeons plan and simulate complex procedures,improve accuracy and safety,and reduce operative time and costs.

One example of 3D printing in automobile manufacturing is the creation of custom parts for classic cars and discontinued models. 3D printing can help restore and preserve these vehicles by producing spare parts that are no longer available or too expensive to obtain.

3D printing in mold manufacturing is the use of 3D-printed sand molds for metal casting. This method can reduce the cost and time of making complex-shaped molds,as well as enable design flexibility and customization.

By using 3D scanning and printing,we can reproduce the details and textures of the original sites,allowing visitors to experience them without damaging the heritage. That demonstrates how 3D printing can preserve and promote intangible cultural heritage,such as oral traditions and rituals.
