3D scanning

Generating a full 3D model to make accurate virtual copies of parts

Can be applied to:

metals, plastics, composites, coatings, adhesives, 3D prints

Test method standards:

Acceptance test complying with VDI2634
GD&T measurements according to ISO GPS and ASME Y14.5

Test procedure:

A light pattern is projected onto a part and captured by two cameras. Thanks to those two “eyes” a virtual 3D surface of the part can be generated. By moving around with the device, a very accurate, full 3D model of the part (accuracy approx. 0.03 mm) can be generated. This can be used to make virtual part copies, assess any dimensions or compare the real part to the original CAD file.

The parts size can range from a few millimetres up to 10 m. If parts are transparent (like glass) or very shiny or reflective (like a mirror), a thin powder coating is applied, to make the surface mat and prevent bad measurements. A few referential elements (small rounded stickers) are placed in the direct vicinity of the part, which are used by the sensor to position itself in the room.

Specifications, based on measurement volume selected:
Resolution : 0.05 – 0.17 mm
Accuracy : 6 – 10 µm
Part size : a few millimetres to 10 m (thanks to TriTop device)
