I believe you can. I'm not a lawyer, but over the years the NC clause of Creative Commons has been interpreted to mean that you can't make a profit from sales of the product; recovering your production costs has typically been allowed. I believe that there used to be an example to that end on the CC FAQ, but I'm not sure.

In any instance, the copyright holder is allowed to offer additional or alternate terms. They may very well say "you can sell a printer made from these plans, but the sale price may not exceed your cost of the materials used" when they release it.
