Independent testing
How much independent testing exists for each 3d printer
Of the 19 3d printers we track, 19 have been physically measured by at least one independent lab. Below is every one, ordered by how much independent hands-on evidence stands behind it — densest first.
A coverage record, not a ranking of which is best.

Each figure is a count of what independent testers actually did — how we count. A low count means little independent evidence has been gathered yet, never that a product is worse. See also the 3D Printers buying guide and the reviewers we cite.
