Thanks for your response CA; well that is a shame as I was hoping to make the larger panels mainly.

In terms of smaller parts such as wing mirrors etc (max size 50cm x 50cm) what kind of printers are available which are not only cost effective but will also do a good job printing?

I guess I will test it out with a 'cheaper' and smaller printer and if I can get the process right and good enough to use the parts; and if it goes well then I will consider investing for one of the large scale printers at a later date.

So are we saying that there are no printers/ 3d printing is the wrong technology to use for this kind of thing in terms of level of sanding required; as ideally I guess I want something which will produce the item almost perfect so I do not need to spend longer than 30 mins making sure that it is ready to spray.

Does anyone know links I can look at to see the quality of a 3d printed item (at 0.1mm vertical print or similar quality)

How long would it take to print something the size of a wing mirror?

Thanks for any replies.
