I have seen some synthetic ethu skins over the years and have always thought them to be rather regular and simple. So I thought I might look at another way of producing one. One idea is to scan an erhu skin and produce a copy in polyurethane. Then I thought maybe scan a single scale and produce an array but that would make it obvious that it was artificial. This is just some fun however if I take it further I will produce some sheets of polyurethane with the different ideas I've got. Here are some pictures of the process along with a 3d printed test. I would welcome any thoughts on what is the perfect erhu skin.
I like that idea. Think that the thickness and flexibility of the print is very important for the sound. When you're done, will you actually mount the skin on an erhu? I am very curious about the sound. Do you place a sound clip?
