In, conclusion I should just like to say future of 3D Printing, there are limitations. But if we can overcome limitations here? The future of 3D Printing is bright. Down by printing out of use without hiring factory from abroad. The consumer then may not to travel to buy small can repair the device to use the various components. And the "print" come out, so the word "revolution" might not far beyond the reach and let me finish there.Thank you.
