3D Printing: A method of creating physical objects such as toys, food, or body parts using a machine that is controlled by a computer program. The program instructs the machine on how and where to deposit raw material (the “ink”) in layers to form a three-dimensional object.
acceleration: The change in speed or direction of an object.
Aerodynamic: Having a shape that reduces resistance to air flow.
air pressure: The force exerted by the weight of air molecules.
composite: A material made by combining two or more different components to create something with enhanced capabilities. An example is carbon fiber reinforced polymers, which are strong plastics with carbon fibers embedded in them, often used in lightweight bodies for race cars and airplanes.
engineering: A field that uses mathematics and science to solve practical problems. Individuals who work in this field are called engineers.
Power: An external force that changes the motion of objects, brings objects closer together, or creates motion or stress on stationary objects.
generation: A group of individuals born at around the same time, considered as a single group. For example, parents belong to one generation of a family and grandparents to another. The term can refer to human age classes or other types like electronic devices.
lattice: Made by arranging strips of material at angles to create a pattern of openings. Trellises are often used as screens or fences to allow air and light to pass through.
Maker: Refers to individuals who make things themselves rather than buying commercial products. Many makers use 3D printers to create items as needed.
Mechanical Engineer: An individual trained in studying motion and material properties to design, build, and test devices using physics.
monitor: To observe or test something, especially regularly or continuously.
Sensing: Being aware of something through the senses or the process of becoming aware of something.
PhD: An advanced degree awarded by a university after years of research that generates new knowledge.
polymer: A substance made from long chains of repeating groups of atoms, including both manufactured and natural polymers.
pressure: Force applied uniformly over a surface, measured as force per unit area.
resistance: Something that impedes the movement of a physical material, often due to friction.
sensor: A device that gathers information about physical or chemical conditions and transmits that information to scientists and engineers.
vapor: Acronym for Science, Technology, Engineering, Arts, and Mathematics.
technology: Application of scientific knowledge to practical purposes, especially in industry.
Individual: Something unique and unlike anything else.
