To the Science Museum in Kensington. We're here to see the exhibition on 3-D printing. It's a bit underwhelming though. Too many words and pictures and too few actual 3-D artefacts. Some pretty interesting concepts all the same. Over five and a half million people have been given 3-D printed implants and body parts. Not everything printed has to be plastic either. Biological materials and even living human cells can be used and it's possible to do very accurate custom adjustments.
Some of the historic exhibits are actually more satisfying though, because there's more to see. For example Robert Stephenson's locomotive:
