I see I see. Yeah, it's a little unfortunate for those in your situation. I'll bet though that Shapeways will eventually put in the security protocols that would allow drop shipping from other countries. All in good time. Keep in mind that if you order your products in bulk you save on shipping to you because you only pay shipping once for multiple products being shipped to you.
One thing I've noticed about my international customers is they don't seem to worry too much about shipping costs for some reason. Perhaps they have it in their mind that if they're going to make an international order that it's going to cost a lot more for shipping so they don't hesitate too much.
In the meanwhile, perhaps you could look into Fulfillment By Amazon. This is where you send your products to Amazon and they store the products in their warehouses and ship the products to your customers when you get orders.
Then again, Shapeways is good too! If you can direct your customers to Shapeways you wouldn't have to pay Amazon or eBay selling fees. What I would try to do is find out what kind of people buy sculptures like yours and then find a way to advertise to them. Also, make sure you have all the keywords that people will use to find your sculptures, like desk art, figurine etc. That way people can find your products by simply searching Google, Bing or Yahoo.
Another thing, who says you have to stick to retail? Find out what retailers will buy your sculptures at wholesale prices. Price wise, wholesale sells for about half retail. You would only make something like a few dollars on every unit, but you sell them 10 or 20 at a time. Another benefit of wholesale is the advertising factor. Every time someone buys your product it then gets word of mouth advertising that builds your brand name. If you have multiple retailers helping you sell you then also have multiple ways people get to know your brand.
