Home inventors will be able to save a lot of time and money by being able to produce and test their own designs without the involvement of secondhand vendors, and thus take their creation to patent quicker. One negative thing I see in these machines is the loss of actual craftsmanship and jobs, this unfortunately is an all-too-real by-product of most technological advances. This, along with outsourcing jobs to other countries, is why I am no longer in the toy industry, so for every advance there are some steps backwards. But for the highly motivated there are also new opportunities to learn new skills and get involved with some really cool new advancements in science.

These new printers are getting so exact that it is now possible to print something like a gear box in one print that actually works! Yes that's right, it gets printed with parts inside one another, things that need to move and rotate, etc. and it actually works once it is printed. The more technical printers such as these use lasers to harden special plastic compounds in ways a mechanical printer could not. Just like how laser printers print the micro dollhouse books that a regular drip printer cannot.
