LEGO Launches Its Second Mass-Produced 3D Printed Part: A Playable Miniature Piano in the Venice Canals Set

On October 17, 2026, Nanjixiong learned that the LEGO Group had introduced its latest 3D printed part: a playable miniature street piano. The part is one of the 5,682 pieces in LEGO's new Icons set, "Venice Canals." A small vase element on top triggers a rotary mechanism that plays a simple tune.



LEGO has not specified which additive manufacturing technology it used, but the black part is likely made using selective laser sintering (SLS), as was the miniature train in last year's "Holiday Express Train" set. LEGO previously disclosed that it uses EOS SLS machines. The set will go on sale on November 4 at a price of £449.99.

LEGO has used polymer 3D printing for prototyping for more than a decade. Last year's Holiday Express Train was its first mass-produced product to use additive manufacturing. LEGO also uses metal 3D printing to make molds. Former senior additive manufacturing manager Mandanà Moshiri called it "crucial" and said, "without it, some LEGO parts would simply be impossible to make."

Nanjixiong observation

LEGO is bringing 3D printing from behind the scenes to the finished product, moving from prototypes to mass-produced parts. SLS makes moving mechanisms possible that conventional injection molding cannot achieve, a positive signal for consumer 3D printing applications.
