When NextEngine introduced its first 3D scanner at SolidWorks World 2006, it got my attention. The product is based on the company’s patented MultiStripe Laser Triangulation (MLT) technology. At the time, it was the lowest priced scanner of its kind. If my memory serves me correctly, the price of the new Ultra HD version is the same as it was back then (base price of $2,995), yet the scan quality is now far better.

The small Ultra HD unit is capable of 268,000 points per 6.5 sq cm (1 sq inch), which is very good for such a low-cost product. NextEngine publishes an accuracy of +/- 0.125 mm (0.005 inch), although it is capable of +/- 0.025 mm (0.001 inch) accuracy under optimal conditions, according to Dan Gustafson, director of marketing at the Santa Monica, California company. When running the scanner in “Optional Extended Range Mode,” which covers a scan envelope of 55.9 x 41.9 x 27.9 cm (22 x 16.5 x 11 inches), accuracy is +/- 1.14 mm (0.045 inch).

An interesting tool for comparing low-cost 3D scanning options is located here. Click each of the models near the bottom of the window and play around with them. When selecting one, it splits the window into quadrants, as shown in the following example, with each representing a different scanning solution. Click and drag the circle at the center to increase or decrease the size of the quadrants. Click the small circles near the bottom to create different views of the 3D model.

The functionality built into the NextEngine website is one of the best and most effective I’ve seen for comparing products. My only suggestion would be to include at least one product that is priced similarly or higher than the Ultra HD scanner. Other than that, the people at NextEngine have nailed it. Congratulations to NextEngine for 10 years of commercializing low-cost 3D scanning products based on MLT technology.
