Well of course. Pricing is listed by CM3. It's always good to have a cheep, fast method to prototype, then determine the best technology to produce a final product.
The nice thing about metal 3D printers is that there's very little pre-production setup like you have with a CNC or other fab tools. Everyone can have a custom product with each print and there is very little switch over costs (efficient run of 1). Read the FAQ / pricing model for the links I provided. There are no volume discounts.
Also, I imagine 3D coops and group investments will emerge and democratize ideas for physical goods. The cost curve will dip rapidly.
Excellent links for this new technology and good tips and pointers.
