    Hi all,
    I'm looking to replace a plastic part that broke on my sony headphones. If tried to source the original part myself but my efforts have been fruitless. If I glue the part together, is there anywhere I could get a replica part printed. Are the any walkin places in dublin that offer this service? Is it expensive? Any help would greatly appreciated.
    Stephen.

    Hi Stephen, What size part are you looking to replace? Do you have CAD of the part?

    If it's a small detailed part you need, or if you need a 3D model created, getting a part printed is going to cost you more than replacing the headphones! 3d printing hasn't really reached the point where you can easily find a drop in service.

    If you can do the CAD yourself, an online print service like Shapeways or i.materialise.

    Hi there thanks for. The reply. This is the part I'm looking for.
    http://www.fullcompass.com/product_image.php?imageid=95979.
    The headphones cost €140. Would this part be expensive. I have no cad. I do have the broken part still. It's glued together, but is not strong enough to support the ear cup. It would be a shame to bin such good headphones because I can't source this part. The online shop won't take international credit card orders under $200 usd.

    If you can't get it 3D printed have you thought about getting it made out of metal (Aluminium or Brass maybe) in a workshop?

    I've no idea of how much it would cost either though.

    Even though its a small and relatively simple part you might struggle to find a comecial place to make it including the drawings.

    You might be able to get someone at a hackerspace to print you a part: http://hackerspaces.ie/
    Your other option might be to make a silicon mould and resin cast the part: Wikipedia - Resin casting

    This is hearsay but I've heard of a 3d scan service using the Xbox kinect...
    Now I can see how this is plausible, but how would it know what was on the inside??? Maybe it just prints (designs/scans) the part as solid.

    andromeda76, I'm quite sure that folks at cadtutor.net forum [1] could model it for you in no time for free, but you'll need to get detailed measurements (vernier caliper required) + some photos of the item from different angles. There are quite a few students looking for practical experience and I can help to organise it.

    3D printing should be easy with some online services, but it's still quite pricey.

    I designed a galaxy S4 car holder a while ago [2] and printed it using [3]. The plactic is quite strong, but flexible. I use that holder every day for over a year now. The only downside is the surface finish - it's not smooth nor black (see photos).
