Do 3D Printers Dream of LEGO Sheep?
Originally published on hackaday.com by Heidi Ulrich on 9 December 2024
The idea of cloning rare LEGO pieces, such as the coveted €50 LEGO goat, using a 3D scanner is an intriguing prospect for fans and makers alike. Balazs from RacingBrick explored this challenge with the Creality CR-Scan Otter, a compact and accessible scanner designed for hobbyists. The goal was to replicate intricate LEGO designs, testing the scanner’s capabilities on various shapes and textures, including DUPLO animals and complex pieces like metallic jaws.
While the CR-Scan Otter handled larger, blockier pieces reasonably well, the glossy and reflective surfaces of LEGO bricks introduced challenges. Achieving high-fidelity scans required multiple attempts and the strategic use of 3D-printed tracking markers to improve accuracy. The results varied: some pieces, like the DUPLO sheep, translated well, while others, including the intricate goat, revealed imperfections that highlighted the limitations of current consumer-grade scanning technology.
This project emphasizes the exciting potential for customization and replication of small objects, particularly for hobbyists who enjoy personalizing or expanding their LEGO collections. However, as Balazs’s journey demonstrates, the process is far from straightforward. Achieving perfect replicas demands patience, creativity, and a willingness to embrace trial and error.
For those intrigued by the idea, this project offers inspiration and a realistic view of what’s currently possible. It’s a fascinating dive into the intersection of technology and play, sparking ideas for how 3D scanning and printing can complement traditional building blocks. For the full details and lessons learned, check out Balazs’s exploration of this geeky endeavor.
