The Stamford New Road facility has been welcoming makers since it opened its doors last spring and all upgrading and renovation work is now complete.
Fab Labs - digital fabrication laboratories - were set up to inspire people to turn their ideas into new products and prototypes by giving them access to a range of advanced digital manufacturing technology.
The Trafford Fab Lab is a collaboration between Trafford Council, Trafford College and the Manchester-based Manufacturing Institute who will run the facility.
Neville Chamberlain, chairman of the Manufacturing Institute said: “Fab Labs go right to the heart of our mission - to support manufacturing. Altrincham is the perfect spot for a Fab Lab.
“We’re right in the middle of the town centre, with great public transport links, and we have the fantastic support of our partners Trafford Council and Trafford College."
Cllr Sean Anstee, Leader of Trafford Council, said: “I am delighted to be involved in the launch of the new Trafford Fab Lab which is an excellent example of partnership working between the Council, Manufacturing Institute and Trafford College.
"Trafford Fab Lab will be accessible to all residents young and old and local businesses to encourage entrepreneurship and the growth and development of manufacturing skills. Trafford Fab Lab has got off to a great start and I look forward to seeing it go from strength to strength. "
And Altrincham artist John Lockwood who is a regular Fab Lab user added: “The guys there are brilliant. You can do your own projects and there is a great team spirit. People are always happy to talk about what they are doing and always ready to give you advice.
‘You can pay for commercial time, or go in on the community days and work on your own stuff just paying for materials.”
