Cocreat 3D [very stylish 3D printing arm/hand startup]

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.

Mad Max Fury Road – fictional arm amputee “Imperator Furiosa” played by Charlize Theron [review]

Again, the Punch & Judy department of Warner Brothers throws a faked disability, a faux handicap, at us, in their Mad Max: Fury Road (2015) movie, and again, we consider it, just as we considered the attempts in Kingsman, or, Home of the Brave (2006), or, maybe in the ill-fated attempt for cinema titled “Hancock”.

So, here they go again; what do they do there? Is it good? And, before glorifying it just because [link][link] (they even write “watch Furiosa punch Max in the face, with her nubbins” which she really doesn’t; she punches him with her hand while sticking the nubbins out in the air) – why not actually *use* our eyes, to look, to ogle, to view, and (in a more strict sense) “watch” it? It is so much a visual and so not much a verbal movie so we really have to switch on our eyesies. What is there to be actually seen, what do they really show? Is this empowering or what does it really say?

Prosthetic arm – details, features

The prosthetic arm in Mad Max: Fury Road in essence contains a glorified claw.

It is notable that the usage of hooks and other non-human looks previously were used as elements of evil, and of non-humaneness [link]. The repeated medial distortion did have a serious impact as it deterred thousands of arm  amputees from accepting a functional prosthetic hook and spawned a whole industry of rubber puppetry dubbed “bionic” hands [link] that cost our health and accident insurances hundreds of thousands of dollars – which would be alright were these hands even halfways “useful”. But far from it, and not a word of apology of any of these media clowns.

Now here, a prosthetic arm is presented that hangs off the digitally edited screen appearance of Charlize Theron who appears to not contain a physical handicap herself.

This arm here was called “Dayna’s arm” simply because Charlize Theron’s stunt double, Dayna Grant, was wearing it for the shootings. For some reasons, an attempt appears to have been made to involve a handicapped actress as “stunt double”, Annabelle Williams, but after preparations and hopeful visions she seemingly dropped from the list of people that actually shot the movie: “Williams might be the only Perennial intern who has to fact-check her own Wikipedia page. She received calls from friends who were surprised to learn from her entry that she is an amputee. The page has since been updated for accuracy, but occasionally the Aussie is happy to indulge others by telling outrageous stories about a shark attack, rather than the real reason that she has no left hand and forearm: a congenital limb deficiency. Her Wikipedia entry also says that she was cast as a stunt double for Charlize Theron in Mad Max: Fury Road. That part is true. But she lost her role when filming moved from Australia to Africa. Williams didn’t get to film any scenes for the movie, but she did meet Theron and learned Muay Thai, a fighting style. “It was quite confronting,” she says of the training. “I had never punched anything. It was like a Billy Elliot movie.””

Blognews, Behinderung, Fairness [rant]

Es gab im letzten Jahr einen wirklich kurligen Blogbeitrag zum Thema Fairness und Behinderung im Sport, und zwar den bei Frau Gehlhaar [link]:

Es ging um den Sportler Markus Rehm. Er ist Leichtathlet und unterschenkelamputiert. Mit einer angepassten Prothese nahm der Paralympic-Sieger jetzt zusammen mit nichtbehinderten Sportlern an den Nordreihn-Meisterschaften teil und konnte aktuell Gewinne für sich verbuchen. Sein sportlicher Erfolg brachte ihn ins Gespräch und in die Presse. Klingt erstmal ganz normal. Jemand gewinnt einen Wettkampf und bekommt dadurch die Aufmerksamkeit der Medien. Die Geschichte hat jedoch einen bitteren Beigeschmack. Es wurden Beschwerden laut, dass Rehm durch seine Prothese einen deutlichen Vorteil gehabt hätte und somit seinen Konkurrenten, im wahrsten Sinne des Wortes, einen Sprung voraus gewesen wäre. „Untersucht werden soll, ob die Prothese von Markus Rehm ein unerlaubtes Hilfsmittel ist, mit dem ein Vorteil bei Wettbewerben mit Nichtbehinderten erzielt werden kann“, erklärte DLV-Präsident Clemens Prokop der Nachrichtenagentur dpa. Der unterschenkelamputierte Leichtathlet Oscar Pistorius hatte sich vor zwei Jahren seine Teilnahme an den Olympischen Spielen und Weltmeisterschaften rechtlich erstritten. Der Fokus auf dem damaligen Rechtsstreit lag auf Pistorius‘ Beinprothesen und inwieweit sie ihm Vorteile, aber auch Nachteile beim Start, Absprung, etc. beschaffen könnten.


Als erster Sportler mit Behinderung durfte Pistorius schließlich an den Olympischen Sommerspielen 2012 in London teilnehmen und fand sich am Ende auf dem achten Platz wieder. Aber was wäre gewesen, hätte Pistorius, wie sein Sportkollege Rehm, ganz oben auf dem Treppchen gestanden? Wären seine Prothesen dann auch als eine Art Wettbewerbsvorteil negativ aufgefallen? Markus Rehm hat im Vergleich zu seinen nichtbehinderten Konkurrenten gute sportliche Leistungen erzielt und somit die defizitorientierte Sicht auf Behinderung widerlegt. In der Diskussion ändert sich aber der Blick auf die Prothese, die auf einmal nicht mehr die Behinderung definiert, sondern angeblich einen “Wettbewerbsvorteil” bringt. Es ist schon fast amüsant, wenn es nicht so traurig wäre, wie Rehm nur über die Prothese definiert wird.


Markus Rehm wurde in Ulm am 26.7.2014 mit 8,24m Deutscher Meister, in einem nicht-behinderten Wettkampf, in dem er nur und ausschliesslich wegen der Prothese gewann, einem Federbein, auf dem er absprang, also, auch sein Sprungbein. Mehr an “definiert” geht gar nicht, was Weitspringen angeht. Anschliessend wurde er für die Europameisterschaft der Nichtbehinderten gesperrt:  “Messungen der Biomechaniker hatten ergeben, dass Rehm beim Anlauf kurz vor dem Absprung deutlich langsamer war als andere Männer bei vergleichbaren 8-Meter-Sprüngen und er trotzdem beim Absprung eine höhere Vertikalgeschwindigkeit erreichte als Christian Reif” (link ). Der allermerkwürdigste Satz schliesst somit direkt an Frau Gehlhaars eben zitierten Text an, er lautet so:

Ich möchte an dieser Stelle nicht diskutieren, ob und welche Vor- oder Nachteile solche Prothesen bringen können.

To be “authentic” in conjunction with being an arm amputee and prosthetic arms?

Nothing kills authenticity like ubiquity. Gilmore JH, Pine II, BJ (2007) Authenticity – what consumers really want. Harvard Business School Press, Boston Massachusetts, USA.

“I want people to let go of their ‘fake arms’; to disarm their limits.” – “When you are authentic with yourself and others, you life yourself up to new levels of clarity, truth, and purpose.” Jessica Cox,

Regarding authenticity, “each one of us has his/her own way of realizing our humanity, and that it is important to find and live out one’s own, as against surrendering conformity with a model imposed on us from outside” (475). [link]

Three axioms of authenticity: Axiom 1. If you are authentic, then you don’t have to say you’re authentic. Axiom 2. If you say you’re authentic, you better be authentic. Axiom 3. It’s easier to be authentic if you don’t say you’re authentic. Gilmore JH, Pine II, BJ (2007) Authenticity – what consumers really want. Harvard Business School Press, Boston Massachusetts, USA.

The call to let go of fake arms is, itself, a fake call to arms. It is as hollow and ultra modern as the call for authenticity as such, as it now requires all to submit our visions towards its cause. However, how far does this theater go? What does it comprise?


Because, these days, it has become widely “hip” to “be authentic”. The common battle cry is “be authentic!”. As a social trend, we are caught in a Catch 22 of modern times: the requirement can not be fulfilled. The direness of the predicament effortlessly develops from the above quotes. We will see that that societal demand, “everyone now be authentic”, is every bit as fascinating and difficult as if you yell at someone “be spontaneous!”. Because the actual problem with this is a logical one: Rene Descartes walks into a bar, after which the bar tender asks him “did you order the beer?” and he replies “I think not” and *poof* disappears.

With a very similar rational explanation, the current quest for authenticity is not one at the same time. It is as non existent as it is non justifiable, non rooted, and senseless. Also it is totally impossible to conduct.

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.
