I was wondering if anyone had any experience of 3D printing We have broken on of our wind generator blades and I now discover that the manufacturer and has gone bust and spares are not available. Would it be appropriate to ask a 3D printing company to make me a new set by scanning the surviving blades? Would the printed material be strong enough for replacement blades? Simon

Simon, I remembered a PBO article about 3D printing of replacement parts.You might try to contact the author. http://www.pbo.co.uk/expert-advice/3d-printing-boat-parts-20440 Daria

Thanks Daria that 's really helpful. I see some have used 3 d printing to make wind generators so I will explore this further and let you know how I get on.
