The exciting part isn't just making something in meatspace, if it was we'd just bake cookies. It's the ability to effortlessly duplicate a design, which can be shared, improved upon, and manufactured with repeatable precision.
Now, as far as building parts with the strength of metal, there are 3D printers that use metal, but they are expensive multi-stage processes. I can only imagine that they will get better/less expensive with time.

ananyo writes "LSD has potential as a treatment for alcoholism, according to a comprehensive retrospective analysis of studies published in the late 1960s and early 1970s. The researchers sifted through thousands of records to collect data from randomized, double-blind trials that compared one dose of LSD to a placebo. Of 536 participants in six trials, 59% of people receiving LSD reported lower levels of alcohol misuse (PDF), compared to 38% of people who received a placebo. The study adds to the weight of evidence that hallucinogenic drugs may have important medical uses, including, for example, the alleviation of cluster headaches."
