Of course, based on the number of units sold of these machines, you can assume they are of some quality. You also know the capabilities of the printer, the kind of filament it can handle, its footprint, and, well, pretty much everything about it.
And you also have, in most cases, an established company you can go back to when things get squirrelly.
But the way 3D printing is evolving, just like computers, the minute you buy it, it’s obsolete. The newer printers can handle more exotic filaments, create larger and better prints. But you have the same 3D printer.
That’s one of the advantages of having a printer that’s built by a small company or even open source ….
