The notable civilatory achievement of being able to "print 3D hands" is a media hype thing. No one that I know personally wears one.

But it is interesting to use this technology. 3D printing, that is.

It is intriguing that overly massive media pressure can bring proponents of new ideas in prosthetics to crawl back.

If, as typical in prosthetic arms since over 100 years (e.g., Carnes Arm, or, Russian Arm), "new products" are hyped up to no end, this can be a logical result: expectation and reality differences are stretched until a snap occurs.

Prosthetic advancement knows no limits. Chinese high quality manufacturing has reached new heights both in computer [link] and automotive technology [link]. With that, rapid prototyping with advanced laser sintering [link] has reached unprecedented new levels in arm prosthetics [link].

Cocreat 3D now sets out to print prosthetic arms/hands. Great designs! And not just that.

Scott J. Grunewald at 3dprint presents a superbly written article that is extremely unusual for its very authentic and clear content, far off the totally confused if not misguided direction that usual media hypes convey:

While working 3D printed hands and mechanical limb replacements have been getting a lot of attention lately, in reality they aren’t really for everyone or for every situation. Motorized prostheses are extremely expensive, require regular maintenance, and are considered by some people who do not have upper body limbs to be more trouble than they are worth. Many people who are missing arms or hands actually have multiple prosthetic devices for different situations, or even eschew them entirely. Additionally people often assume, if someone is missing a limb or has any sort of noticeable disability, that something happened to them when in actuality it often it is something that has been part of them since birth. The automatic assumption that missing a limb makes someone broken and needs to be fixed is frankly a rather onerous one and it is high time that the behavior be addressed. The fact is, most disabled people don’t have the luxury of “fixing” their disability and rightly resent the implication that they are required to do so. Subtle forms of ableism like excessive displays of pity of being inspired by someone with a disability because they “manage” having a disability can often be rather demoralizing and actually have the opposite intended effect. Whereas someone choosing how to present and acknowledge their disability is actually an important personal statement that shouldn’t be taken from them. So while 3D printing is giving an entire generation of people access to useful and affordable prosthetic and assistive devices, it has also given them the ability to define the nature of their device and customize it to their personal needs. And because 3D printing is so inexpensive in comparison to traditionally manufactured prosthetics, it also offers the opportunity to consider personal aesthetics. It is that new freedom that has inspired a Colombian 3D printing business to create a series of 3D printable prosthetic devices designed to be seen and noticed. “We present a series of 3D printable passive prosthesis designed for upper limb amputees. We aim to make uncommon prosthesis that are not meant to be hidden but to be shown without shame,” explained designer and Cocreat3D CEO Esteban Velásquez Rendón. Cocreat3D is still in the prototyping phase of their design process and currently has only printed scaled down versions of the prosthetic devices, but they should be available soon. The prosthetic devices can be custom fit to the wearer’s arm using 3D scanning and 3D modelling technology, and of course be printed in any color or material desired. And given the wide variety of materials that are available, including metallics, neon, and wood, many of these designs could be quite striking. While Rendón’s devices will not be the first passive or decorative prosthetic limbs to be 3D printed, they are the first that seem to be aiming to create a line of products that can be adapted to any user, not designed for a specific person. And as the cost of 3D printers and materials continues to drop, small-scale, personalized manufacturing is made more accessible to almost anyone. 3D printing technology is leading to the democratization of design and manufacturing and having a very real impact on multiple industries and communities. And now a community that is often marginalized and forced to have their mobility, experiences, and lifestyles defined for them is being given the tools to take that power back for themselves, even in such small, seemingly insignificant (to those without disabilities) ways.

Robert Downey Jr. himself presents a 3D-printed "miracle" [3d printing, Iron Man, plastic hand hype, great looks though]

Here, the previously relevant and important terrain of pragmatic solutions towards prosthetics are totally abandoned. Symbolism has a new level: a symbolic arm now is "handed" over by the actor that plays that "bionic" uber engineer that "built" these. Really and more pragmatically, the hand is more like a Potemkin village of a real prosthesis - but you cannot have everything these days. The thing is termed "miracle". Read up on the aspects of symbolism versus realism [link] when you find time though. The boy now has just left life as it was, and become an actor in his own life. A real life and a possible simulans (prosthetic arm) now have been replaced with a simulacrum (the "Iron Man" prosthetic does not provide a "map" to any "real" item). The slogan is "Dream Big Dreams" (and my add-on is, "but be careful with all that plastic, it may break before you know it").

The looks of the hand are great though. Best thing since I came out with the official Red Hand in 2009 ; )

Unbelievable! Great people involved there though. Robert Downey Jr. could not have done a better thing. Maybe Touch Bionics or RSL Steeper want to get involved with "Stark Industries" as well at some point.

From the MAKE website [link] we now read that some design student by the name of Evan Kuester [link] came up with the coolest actual 3D prosthetic ever. We did see great prototypes that never made it to any amputee - but here, things are totally different. Here the design starts on an arm that wears it, and it does create the smiles such an arm is supposed to create.

Under the auspices of Joanne Tilley, an arm amputee and artist, and Magnus Feil, professor at the University of Washington, students designed prosthetic arms in the autumn quarter of 2009 with new and definitely interesting results.

As we still ponder new prosthetic arm designs and while 3D printing becomes ubiquitous and when toying around ideas in general, let us re-consider these results.

It is funny that of all magazines, the "Fast Company" (again) should come up with an interesting article:

http://www.fastcodesign.com/1672389/a-3-d-printer-for-every-home-yeah-right

They write:

"While 3-D printing will excite hobbyists and disrupt many industries--and in fact, already has--its consumer application has been vastly exaggerated in ways that a lower cost and higher printing resolution won’t solve."
