The LEGO Group have announced the inclusion of a 3D-printed blue train element in the October 2025 LEGO® Icons set 10361 Holiday Express Train, and sent us a copy.
While this is not the first LEGO 3D element by any means, it will be the first time one has appeared in a regular retail set with wide availability. This seems like a good opportunity to take a look at the LEGO 3D-printed parts we have encountered so far, and where they might take us.
