Which of the following is a common tool used in engineering technology?

The selection of 3D printers, laser cutters, and CNC machines as a common tool used in engineering technology is justified by their essential roles in modern design and manufacturing processes. These tools enable engineers and technicians to create precise prototypes and components, facilitating rapid development and iteration of designs.

3D printers are particularly significant in engineering technology, as they allow for additive manufacturing, where objects are built layer by layer, offering flexibility in design and material usage. Laser cutters provide high precision in cutting various materials, making them valuable in tasks ranging from prototyping to manufacturing. CNC (Computer Numerical Control) machines automate machining processes, significantly enhancing productivity and accuracy in material shaping.

While hand tools and wrenches are fundamental and widely used in engineering tasks, they have more limited applications in complex technological processes compared to advanced machinery. Project management software is important for organizing and managing projects, but it does not fall under the category of physical tools that facilitate engineering tasks directly. Standard calculators are essential for performing calculations, but they do not encompass the technological and manufacturing aspects central to modern engineering practices as effectively as the combination of 3D printers, laser cutters, and CNC machines does.
