@tovarichpeter, really, you should consider using the comment feature instead of only ever posting new threads. You have already several threads on 3-d printing, for example this one about Singapore. Your irrelevant hashtag insulting another PatNet User does not help, and does nothing to clean up the disorganized mess of scattered Posts about a developing topic.

For anyone interested in the actual topic, rather than making pointless insults "trend", see also these threads:

PatNet has more examples, but the search function doesn't work well enough to find all of them. If you made even a slight effort to find one of your previous Posts on a topic before posting again, you could build a useful reference on a topic.

@Patrick, I may have inadvertently learned something useful from typing my comment above.

SIWOTI motivates people. That can be good or bad, depending on how you harness the resulting energy and what you transform it into.

Long ago, you used to delete comments for direct insults. A better approach might be to treat them like a "swear jar," which harnesses people's anger and bad behavior to fund something everyone might enjoy. Let people say insulting or offensive things, on condition they provide proof or useful information.

Daniel Kahneman called professional peer review "sarcasm," followed by "advanced sarcasm." You've seen what happens with Wikipedia, where people delete stuff they don't like, even if some of it is useful.

You could build something like Wikipedia or peer review, harnessing the SIWOTI motivation on condition that the resulting comments help to build something useful. You said recently that you don't want to ban TOB, who is a Nazi and wants us all dead. That's your choice, but you might choose which of his comments you want to publish on your site. For example, if he figures out a way to make trains run on time, or designs a new rocket engine, you could keep that and delete the pointless insults. America succeeds by harnessing the motivations of many different people who disagree about many things, and getting them somehow to build a shared republic (for better and for worse).

You might encounter a very common conflict of interest: crap sells, and quality doesn't. Journalists have long lamented that a serious investigative report requiring years of work gets less attention than a pointless story about a celebrity sex tape or quoting two politicians insulting each other. Doctors lament that the fee-for-service model rewards injurious malfeasance while punishing good work. Medical researchers complain that public funding goes mainly to private revenue models (pushing daily pills) rather than public benefits (ending diseases). @Rin and others have written persuasively about postdocs with potential languishing while financial manipulators prosper. I've seen my own thread on Parkinson's Disease research languish and get buried under a haystack of speculation about whether a particular politician might have Parkinson's Disease, even though my thread provides a rare example of reporting on related research across countries and years. You might decide, as many executives running large organizations decide, that you want some things that sell and others that people can feel good about. A famously successful CEO said once of a particular publication that wasn't making much money if any, it's worth keeping because employees throughout the organization feel a sense of pride that they work for the organization that publishes it.

Anyway, just a few thoughts resulting from wondering why did I waste time telling tovbot yet again that he should organize comments into one Post instead of littering your site with endless disconnected Posts. I feel the same way about "news" reports: they publish daily with no connection to what they've published previously, and they leave one day's report with no way to follow how that story turned out later. Charles Kuralt made a whole show out of traveling America following up on old stories to see how they turned out. The Interwebs could automate that.

So when can I buy a printed house? Been waiting 10 years.

"Ultimately, 3D printing allows for a more personalized architecture, letting homeowners and business planners have the freedom to dictate how they want their houses to turn out. This frees them from the confines of traditional construction."

So long as you don't mind that they look like Legos.

Mine will look like this:
