Accuracy is quoted for an object size, and the size is part of the figure
A 3D scanner turns an object into a mesh that can be edited, printed or measured, and its headline figure is the least self-explanatory on this site. Accuracy is quoted in millimeters or fractions of one, and it only means something beside the conditions the maker attaches — the size of the object, the distance, and whether the figure is a single-frame or a volumetric one over a whole scan. A listing that prints the number without the condition is quoting the best case. The technology divides the shelf: structured light projects a pattern and suits small and medium objects indoors, infrared suits people and larger forms, and laser lines suit shiny or dark surfaces that other methods struggle with. The object size range is published as a minimum and a maximum, and it is the specification that decides whether a coin and a car door are both possible. Tracking is how the scanner knows where it is: geometry, texture, or small reflective markers stuck on the object, which work everywhere and take time. Then the output formats the software exports, whether processing needs a powerful computer or runs on a phone, and whether a turntable is included. We compare published accuracy and its conditions, technology, object size range, tracking method, output formats and computing requirements.

A blue-laser scanner with a dual-axis turntable, stating 0.02 mm single-frame accuracy and 0.02 mm + 0.04 mm × L(m) volumetric accuracy.
Best for: A shop scanning small, precise parts for reverse engineering.
≈ $1049
It publishes single-frame and volumetric accuracy, with an object range.
It is only worth the conditions published beside it: distance, size, surface type. This site reports them together.
The measurement principle used, published by the manufacturer. It explains the materials on which the device behaves badly.
How the device locates itself while moving: markers, geometry, texture. It is published on every listing.
The published output formats say so. They decide the software chain possible after scanning.
Computing requirements are published. In this shelf they are often demanding.
That depends on the published object size range and tracking method. This site describes no scanning protocol.
It is a known limitation depending on technology. What the manufacturer publishes about it is reported as is.
It gives a mesh, which usually needs work. This site publishes output formats and nothing more.
Match the object size range to what you will scan, and only compare accuracy figures that come with their conditions.
Four machines in five must publish the value before a column is raised. Below that, it would be comparing absences.
