3D scanning captures the shape, size, and often color of a physical object to create a digital, three-dimensional representation. It’s commonly used for design, inspection, and digital archiving.

While 3D scanning captures the digital form of an existing physical object, 3D CAD (Computer-Aided Design) modeling is the process of designing objects from scratch or based on scanned data using specialized software. CAD models are ideal for manufacturing, simulations, and further design modifications.

Reverse engineering involves taking a physical object, 3D scanning it to obtain digital data, and then using it to recreate or understand its design, structure, or functionality. This process helps in recreating parts, understanding competitors’ products, or improving upon existing designs.

Metrology is the science of measurement. In the context of 3D services, it refers to the high-precision measurement of objects to ensure they meet specific standards or requirements. Metrology services often involve tools like CMMs (Coordinate Measuring Machines) and are crucial in industries where precision is paramount, like aerospace and automotive.

Inspection services involve examining objects (often using 3D scanning) to ensure they meet predefined criteria, such as quality standards or design specifications. This can involve checking for defects, ensuring dimensional accuracy, or comparing a manufactured part to its original CAD model.

Companies might need reverse engineering to recreate discontinued or unavailable parts, understand competitors’ products, improve upon an existing design without original CAD data, or bring physical designs into the digital realm for modifications.

The accuracy depends on the tools and methods used. High-end 3D scanners and metrology equipment can achieve micron-level accuracy. However, specifying the required precision level when seeking these services is essential.

Absolutely! 3D CAD modeling provides a digital blueprint of a design. This digital model can be used for simulations and, importantly, for creating physical prototypes using methods like 3D printing, CNC machining, or mold making.

3D inspection provides a detailed comparison between manufactured products and their intended design. This ensures that parts or products adhere to quality standards, helps identify defects or inconsistencies, and can streamline the quality control by offering visual feedback.

Reverse engineering is ideal for this. 3D scanning the old or worn-out part can obtain digital data, which can then be refined using CAD modeling to produce a design suitable for manufacturing a replacement part.
