Decoding Precision: High-Accuracy 3D Scanning of a 0.07 mm Dispensing Nozzle

High-Precision 3D Scanning – Micron-Level Accuracy Beyond Traditional Measurement

In the electronics and optical manufacturing industries, precision is non-negotiable. Scantech VN was tasked with a demanding technical challenge: 3D scanning a precision dispensing nozzle.

Although the overall part is small, the critical feature is an ultra-fine nozzle orifice measuring only 0.07 mm.

Measuring such micro-scale features using traditional methods (calipers, contact CMMs) is nearly impossible due to:

• High risk of damaging or deforming the delicate nozzle tip

• Inability to capture full-field geometry, including concentricity, straightness, and taper

• The 0.07 mm aperture being beyond the resolution and accessibility of conventional measurement tools

This challenge required a non-contact 3D scanning solution capable of handling reflective metallic surfaces and micro-scale geometries with extreme accuracy.

Scantech VN’s Comprehensive Solution

Non-Contact 3D Scanning: From Micro to Macro

To meet diverse accuracy and size requirements, Scantech VN operates a complete portfolio of professional 3D scanning systems.

Solution for Ultra-High Precision (0.07 mm Features)

• We deployed the ZEISS/GOM ATOS Q, an advanced non-contact optical 3D metrology system designed for micron-level inspection.

Scanning Workflow

• A small measuring volume (MV) lens was selected to achieve maximum point density and resolution.

• Specialized scanning techniques were applied to reliably capture data on reflective metal surfaces.

• The result is a high-density mesh model generated from millions of data points, accurately representing the nozzle geometry, including complex micro features.
