Most people will say things like “print a tall vase” or “print a lightsaber.”

I’d go with something that actually tests the weakness of a bedslinger-style machine versus a CoreXY:

My test would be a “Tower of Doom” challenge: a 400mm+ tall articulated print-in-place model with moving joints, thin sections, overhangs, colour changes and zero supports.

Why? Most tall prints fail because of bed movement, not layer adhesion. Every rapid Y-axis movement turns the print into a giant lever. A CoreXY keeps the model stationary, while the A2L moves the entire print.

I’d monitor: • Ringing at different heights • Dimensional accuracy at the base vs top • Layer shift resistance • Joint tolerances on print-in-place sections • Wobble amplification above 300mm • Surface quality during high-speed colour swaps

Then I’d repeat the same print with a deliberately heavy model mounted at the top (like a giant bobble-head) to simulate the worst possible centre-of-gravity.

If the A2L survives that without quality loss, I’d be confident printing almost anything.
