First official 3D printed LEGO piece is a tiny functional duck

Visitors to the LEGO House’s adult fan event were gifted a LEGO 3D printed duck, which was an ongoing AFOL (Adult Fan Of LEGO) project at the LEGO House development studio. Ronen Hadar, LEGO’s Senior Director Additive Design and Manufacturing proudly shared the project on his LinkedIn feed adding that “the team has been working hard to develop, approve and manufacture this super cool element, in collaboration with our talented designers. This is an important milestone for the team. We are looking forward to share more news with you in the coming future.”

As explained in a story by, the classic wooden duck is a piece of LEGO history, recreated in modern bricks for 2020s 40501 The Wooden Duck, which is available exclusively at the LEGO House in Billund, Denmark. While that 621-piece set includes a display stand, the real magic happens when you lift it off and pop it on a flat surface: pulling the string turns the wheels and snaps the beak, just like the wooden duck from 1935.

As a natural evolution of “toy-technology”, instead of the rigid wire used in the original toy, though, 40501 The Wooden Duck uses a combination of LEGO Technic elements to achieve its internal mechanism. As the next logical evolution, the tiny LEGO 3D printed duck handed out to LEGO House visitors recreates all the same functions of its bigger siblings on a much (much) smaller, fully integrated, scale, as a single piece 3D printed by polymer powder bed fusion.

Showing the capabilities of PBF technology, the diminutive red duck is smaller than a LEGO minifigure, but still manages to pack in all the same functionality of turning wheels and snapping beak when pushed along. According to one Instagram user who got their hands on one, the duck is the ‘first ever official 3D printed LEGO element’, but its availability beyond yesterday’s LEGO House AFOL Day is uncertain. In all likelihood, it’ll probably be exclusive to attendees.

Thanks to a tip from Anna Chase, Senior Additive Manufacturing Engineer at the LEGO Group, pointing to an entry by the New Elementary LEGO fan blog, we learned that the duck is actually the second official LEGO 3D printed piece. The very first one, released in 2019, was perhaps even more appropriately, the arm of a drafting machine inside a very unique LEGO piece that represents the opening ceremony of the System House, a flagship office in Billund built in 1958.

The set was made available as part of the “Inside Tour” goodie bag distributed during one of the very exclusive events accessible to a small group of fans, with tickets selling out almost instantly. The lucky participants are given behind-the-scenes access to LEGO HQ, hang out with designers and receive all manner of goodies. The 2019 set is especially contained the drafting machine arm. It even has an ID number: Element ID 6286866|Design ID 66237.

Although surface quality is lower than injection molded parts, the use of 3D printing made sense for LEGO as this is an extremely rare piece produced in very low numbers (whereas the duck shows integrated functional capabilities that are just not possible with injection molding). It is particularly appropriate that LEGO used 3D printing on this part as a drafting machine is a device for producing technical drawings that engineers, product designers and architects use before the advent of computer-aided design (CAD).

A drafting machine comprises a counterbalanced arm leading to a protractor head with a right-angled ruler attached. This enables the draughtsman to draw lines accurately at any angle from anywhere on the page, and it can also be locked to either the horizontal or vertical axis. The LEGO version isn’t quite that flexible but it can move more than an injection molded part would be able to.
