I am currently assembling an Ormerod 2 3D printer at work. It's a fun project - we are not launching into 3D printing services. Not yet... :-)
About three-quarters of the way through the basic assembly.
I've never used one before and, other than the parts of the printer itself, have not even knowingly come into contact with 3D printed parts before. Now I have the opportunity to play with one, it seems not a bad idea to start a 3D printing thread. I know I'd have liked one to re-create a number of small parts for various things around the house!
