VL Series 3D Scanner CMMs can measure large targets in 3D from all directions, providing full 360° scanning capability. The motorized turntable moves in the X, Y, and θ directions for fully automated recognition and scanning of the measurement target. The high-magnification lens captures up 16 million data points, allowing for acquisition of precise data on small targets and complex shapes that cannot be measured with conventional scanners. Full 360° scans can be compared directly against CAD data, allowing for easy detection of deviations from design values, quick determination of good vs. bad parts, and wear analysis before and after use of a product.
VR Series Wide-Area 3D Measurement Systems are capable of non-contact, high-resolution 3D measurement. The VR Series captures full surface data, instead of point or line data typically captured by CMMs or profilometers, allowing small features to be measured with the highest-level of confidence. Automatic place-and-measure capability allows any user to capture accurate data across the entire surface of their part, with no fixturing or adjustments required. The VR Series excels at measuring precise 3D features, profiles, flatness, and roughness.
The shape of the object is measured over the entire surface, ensuring accurate measurements of the profile at the desired locations.
3D measurements of a wide area can be made very quickly.
The high-precision motorized stage features an expanded maximum measurement range of 200 mm x 100 mm. You can obtain accurate measurements with ease thanks to advanced controls such as focus position adjustment and stage inclination correction.
A 3D Scanner captures 3D data of an object's shape for measurement or visualization purposes. 3D scanners come in two types: contact systems which obtain coordinates by physically touching the target with a probe, and non-contact which obtain 3D data without touching the target.
With contact-type 3D scanners, the operator holds a probe against the target object and records the position of the probe as coordinates. This traditional method takes a long time to complete measurements, and doesn't allow for complex shapes or geometries to be fully mapped. Non-contact 3D scanners obtain 3D data by measuring the time difference and emission angle of a laser or other light source reflecting off the target object. Some 3D scanners project a striped pattern onto the target and measure the displacement of the lines to capture data.
3D scanners can measure in both 3D and 2D with easy operation. Set-up and measurement operations are simple, so anyone can measure complex objects with high-accuracy. 3D scanners can measure cross-sections, thickness, and perform GD&T measurements in a single scan.
With conventional measurement systems, many setup steps are required, such as fixturing, stage adjustments, and precise placement of the measurement target. However, with a 3D scanner, an operator is only required to place the target object on the stage and measurement can start right away. Additionally, because the entire surface is scanned, a 3D scanner can perform nearly limitless measurements, including measuring the highest and lowest points across a surface, distances between lines, and distances between circles or other features.
Target objects can be compared directly against 3D CAD data, or against measurement data from a similar part. Comparing target measurement data can help verify conformity and identify defects.
Comparing a 3D scan against the object's 3D CAD data enables visualization of any differences between the final product and the design. Objects that are difficult to measure with conventional approaches, such as parts with free-form shapes or complex geometries, can be quickly compared against CAD data to instantly visualize any areas the part is out of tolerance. Additionally, different sets of measurement data from the same product can also be compared, which allows for capturing changes in the shape of the product before and after use, or for identifying why one part may be working while another is failing.
Reverse engineering analyzes existing products to reveal their specifications, components, and design. A 3D scanner can recreate the shape of a product with high data quality, enabling drawings to be quickly made for already existing products.
Reverse engineering helps determine the manufacturing method and working principle of a product by analyzing the product itself or its components. A 3D scanner can accurately analyze, dimension, and create drawings or DXF files of even complex shapes and products. With the ability to quickly measure objects regardless of their complexity, 3D scanners are optimal measurement systems for reverse engineering.
Metal and plastic materials have plasticity and elasticity that affect the way they are worked, and as such, making industrial products to design specifications can be incredibly difficult. To assess the shape of a product, the entire part must be scanned with a 3D scanner.
With a 3D scanner, measurement of deep drawn products, springback analysis, and plate thickness evaluation can be easily performed. Profile measurement of deep drawn products can be done by visualizing the part against its CAD data, while springback can be analyzed by measuring the difference from cross-sections. In addition, hand tools cannot capture the thickness of a bent part or changes in thickness caused by metalworking, but a 3D scanner can capture the rate of reduction of plate thickness across the entire part.

Injection molded parts can be difficult to measure due to their freeform geometries, and can deform when measured with contact tools. 3D Scanners allow for a wide range of measurements to be performed on molded products, including radii, flatness, and curvature. Warpage caused when the part is removed from its mold can be quickly and accurately measured across the entire part. Additionally, samples from different molds can be scanned and the data superimposed so differences can be instantly understood.

Due to the limited number of data points captured, measuring systems that collect point data may overlook non-conformities that would otherwise cause measurements to fall outside of dimensional tolerances. A 3D scanner can be used to acquire scan data for the entire product to evaluate its true shape.
With a 3D scanner, it is easy to evaluate the shapes of fins of alternators and heat sinks, as well as measure the positions of electrical parts. When evaluating the shape of an alternator, the CAD data can be directly overlayed on the 3D scan to identify any non-conformities. Additionally, the fins of a heat sink can be virtually cut into cross-sections to measure their pitch and height, without destroying the part.

3D scanning accuracy normally ranges between 10 - 100 microns. 3D scanners typically excel at measuring large parts that do not contain small surface features, as the accuracy isn't high enough to obtain high-resolution surface shape data. With the VL Series, high-magnification lenses can be used to capture up to 16 million data points on the surface of a part, ensuring even small features or targets can be accurately measured.
3D scanning is a non-contact form of measurement that captures the three-dimensional shape of a target object through the use of a projected light source. 3D scanners may project a laser onto the surface, and measure the time required for the laser to return to the light receiving element to map the surface of the part. Other 3D scanners project a striped pattern onto the target object and measure the displacement of the lines to construct the 3D model.
3D scanners are used to acquire data on target objects so the user can visualize and measure the surface of the object. Some 3D scanners allow scanned objects to be directly compared against their CAD model, so users can quickly understand how a manufactured part differs from the design. 3D scanners are used in quality control and research and prototyping across many industries, including stamping, molding, casting, and electronics.
