5 Key Ways That 3D Printers Could Improve the Worldselfnews Post The latest technology that is increasing its footprint exponentially (with a subsequent exponential reduction in cost) is 3D printing. And, true to form, the establishment has focused on the nearly free weaponry that could be and, in fact, has been created, from drones to guns. Here is the central concern stated by The Lowy InstitutesAustralian propaganda outlet: However, beyond this obvious smokescreen lies a technology that could easily revolutionize every facet of our lives, exactly as Internet communication has. Let us look at the top 5 ways that 3D printers will change the world for the good if we can resist government and big industry intrusion and insist on the day when there is a 3D printer in every home. Homemade weapons: What the establishment sees as the greatest threat could be one of the single greatest uses for 3D printing to bring freedom on the widest scale the ability for anyone to print a weapon. Every tyrannical regime throughout history has disarmed the public prior to becoming a truly out-of-control killing machine. With the ability for anyone, anywhere to be able to defend oneself and mobilize quickly against a growing threat, governments would have to think twice before heading down the road to tyranny. The fact is that human nature has now been scientifically proven to be inherently non-violent; it is only a relative handful of psychopaths that exist and they tend to seek positions of power or congregate in street gangs. Good people, vastly outnumbering them, must have the equipment to defend themselves while keeping the truly dangerous people (and governments) in check or preferably have them disarmed. Inexpensive Architecture and Artistic Design: The cost of 3D printing has theoretically gone to zero. Singularity Hub ran a recent article covering a new 3D printing app for the iPhone which opens up an array of possibilities for the average user. While still limited compared to more expensive printers, one can easily see the technology rapidly offering new means of creative expression. Truly amazing is the ability to print entire buildings! Naturally this is an area being invested in by the U.S. Department of Defense to the tune of $30 million, but according to Think Defence, a British site: Infrastructure Creation and Efficiency: The basic technlogy offered by the personal app for home devices is being employed in full-scale infrasctructure products such as cables and pipes, and is already beginning to offer some tantalizing benefits. Civil engineers are using a combination of sophisticated 3D laser scanning to model environments for functions such as bridge infrastructure inventories, bridge height clearance measurements, street intersection surveys, and inventories of railway crossings, just to name a few.

Less Manufacturing Pollution: Another interesting application for 3D printing aims to replace a portion of the massive amount of cement binder used in infrastructure projects with something called Stone Spray. With this application, according to Stone Spray creators, architecture can be created from soil. Utilizing a layered 3D printing technique, the core of a structure can be created with a greatly reduced amount of cement, thus cutting the need for one of the most polluting substances currently used in construction (concrete). From the concrete batch plants to urban runoff causing soil erosion, water pollution, to the inherently costly equipment used to contain and recycle concrete, and heavy metal emissions, current infrastructure creation pollutes every step of the way.

Energy consumption is also greatly reduced, and can even be operated exclusively via solar energy, which in turn lowers overall construction project costs, both public and private. Load bearing ability is currently sufficient to produce walls, and it is expected that research projects similar to Stone Spray will increase on a much wider scale in the not-too-distant future. Beyond the larger applications, imagine a 3D printer in every home within a few years offering easily downloadable specifications for nearly all basic objects. One could print a bowl, cup, plate, spoon or Tupperware anytime they needed a new kitchen utensils. Tools like wrenches or screwdrivers could be produced in minutes along with the screws, nuts, and bolts needed for the task. Even parts for medical equipment, power production, transportation, laboratory equipment, etc. would be one click away. There are almost too many possibilities to consider. However, with the many potential benefits of this technology, we would be remiss not to consider some of the negatives. With the current military-industrial system in place across much of the planet, this technology is already in the wrong hands and must be maintained as open source if we are to utilize this for the betterment of humanity. We will examine in an upcoming article some of these negatives to be on the alert for. Main sources for this article: Read other articles by Acivist Post HERE
