<p>Recently on one of her videos a YouTuber stated that prints from large format printers are more brittle than if you were to print them in parts and glue them together. This seems to contradict the testimonials from the customers of a large format printer, who say that they get good prints from those printers (which print have a print area of a meter square). </p>

<p>Would a print form a larger format printer be more brittle than a print made of smaller pieces super glued together?</p>

<p>(with all other aspects being equal e.g. the nozzle, the temps, the material and the shape of the object).</p>

<p>The YouTube didn't cite any source information to back up her claim.</p>

If you break up a large piece into multiple smaller pieces and properly glue them together, you basically add stiffeners (as a result of printing walls). This could lead to a more stiff model; this might have been confused by calling large prints more brittle opposed to constructed models.
If printing is conducted at similar conditions on large printers, there shouldn't be a reason why the model becomes more brittle unless the conditions aren't the same. But that would be true for printing at small printers too, e.g. if one print was printed in a draft.
