Changing Technologies, Inc, a Texan 3D printing service provider, hopes to offer 3D printed replacements parts for LEGO collectors. They specifically have asked LEGO for a license to offer 3D printed replacements for broken, lost or missing pieces that are not available in LEGO’s retail outlets. Any 3D printed replacement bricks or parts would be quite expensive in relation to their mass produced counterparts, but the secondary market for LEGO toys found on online marketplaces like eBay is a huge business, and replacing parts or getting special, hard to find pieces is something that LEGO fans are used to paying a premium for.
