Can incredibly realistic 3D-printed rhino horns stop poachers?

Rhinoceros poaching is an enormous problem worldwide, with an estimated 7,245 African rhinos lost to poachers over the last decade alone. We’ve previously covered high tech solutions to the poaching problem ranging from the use of drones to keep tabs on wildlife populations to an ambitious plan to catch poachers in the act by embedding video cameras directly into the horns of wild rhinos.

An innovative startup is hoping that is has another solution to offer, however: 3D printing.

Seattle-based biotech startup Pembient has spent the past several years working to develop artificial rhino horns it hopes will eventually be indistinguishable from the real thing. These synthetic horns are created with an engineering process involving keratin, the main protein found in rhino horns, combined with rhino DNA. This creates a special 3D printing ink that can be used to create authentic-looking horns.

The theory behind Pembient’s work: These can be pushed into the rhino horn supply chain (primarily in China), so that people won’t know whether they are buying real rhino horn or fake ones. Pembient hopes this will lower the value of wild rhino horn, and severely dent the profits that currently drive poachers to risk their lives killing rhinos.

At present, the company hasn’t created a finished product, although it has created numerous low fidelity replicas. As a result of this, the exact prices for the fabricated rhino horns hasn’t been made public — but it would certainly be cheaper than the real thing. Pembient isn’t stopping at rhinos, either. In addition, it has plans to create 3D printed versions of pangolin scales, elephant tusks, tiger bones, and presumably numerous other biofabricated versions of items that cause the real life poaching of endangered species.

While it remains to be seen whether over-supplying fake rhino horns and other items is really the best approach to counter poaching (personally, we’d like to see this in conjunction with other methods designed to counteract the threat). However, if it can help cut down on the unnecessary slaughter of animals in the wild, we’re all for it.

And, hey, from a biomedical perspective, we’re all for any innovative research that could lead to the 3D bioprinting of more lifelike bones.

The 3D printing market has seen quite a few changes over the last few years. In just the span of a decade, the barrier to entry has dropped from well over several thousand dollars to under $200 in some cases. However, all entry and mid-level printers are not made equal. We have a few suggestions for prospective buyers and other information regarding alternatives not found on this list.

To some veterans of the 3D printing scene, this list may seem like it lacks a few of the most commonly recommended printers for newcomers. This is by design. Our list only considers printers with tested components from proven, reliable vendors. That's why we chose the Monoprice MP Mini v2 as our top pick--it's reliable and easy to use. We have avoided any printer with a frame primarily made from interlocking acrylic pieces and anything historically unreliable.

Scientists use a novel ink to 3D print ‘bone’ with living cells

The term 3D bioprinting refers to the use of 3D printing technology to fabricate biomedical parts that, eventually, could be used to create replacement organs or other body parts as required. While we’re not at that point just yet, a number of big advances have been made toward this dream over the past couple of decades.
