  1. How could l make some like this ? I would like help people who needs a hand.. Im from Mexico, and I would like be a volunter, congratulations for your work

      • Thank you very much, I hope I can help, I am a student of bionics engineering in Mexico, I hope to help in the future in a more direct way, for now I’ll find a way to help as you and again, congratulations for your work!

    • Hola Isaura donde estas en Mexico yo estoy en Tepoztlan Morelos tengo una impresora, tu imprimes? a mi también me interesa ayudar , y estoy mas que dispuesto a poner tiempo de mi maquina y material para esto . quizás podamos ir juntando fuerza aquí en mexico también .

      • Hola, espero que podamos unir fuerzas aquí en México en donde lo que más necesitamos es ser solidario, ojalá podamos ponernos de acuerdo.

      • Soy de Morelos, pero actualmente estoy en Puebla, ojala podamos ponernos deacuerdo

      • Hola a todos, yo también estoy en México tengo 2 impresoras, este proyecto es realmente apasionante he estado imprimiendo algunos de estos modelos, ojala podamos estar con contacto para hacer crecer esta comunidad en México realmente hay muchas personas que tienen impresoras en nuestro país creo que todos podríamos aportar.


        Hola! Este enlace le llevará al formulario de admisión que ayudará al equipo matcher conseguirle que aparece como un fabricante!

    • I’m also located in Mexico City and just joined the community. I have a 3D printer and would love to both print and design.

    • Hello!

      If you have someone that is in need of a device who is missing fingers – please send an email to our matcher team at and they can help find someone near you to help! It may take a few days for them to get back to you as we are all volunteers and do this in our free time so please give them some time to get the info to you!

  2. Hello!

    My name is Spiro. Im a 25 year old man from Greece now living in the UK.
    First of all i would like to congratulate you on such a wonderful achievement! I myself was born with missing digits on my left hand due to congenital amniotic band syndrome. Its where the amniotic sac constricts a part of the body and prevents it from developing when in the womb. I have coped without any prosthesis or support whatsoever my whole life because of the cost of having something like this done. It is absurd and ridiculous to price a prosthetic at such a high cost as 35k and over! But thanks to people like you there is hope for someone like me. What would it take to possibly get a hold of one of your devices?

    Best wishes,
    Spiros Pouliasis

  3. Hello I’m Jeff and I live in the Philippines. Would you know anyone in this area who can help me have this hand… I lost my right hand due to an accident but I still e my carpal and wrist intact… My dad lives in LA in the united states maybe I can have one shipped to him then he can send it to me here in the Philippines… I really appreciate all these things your doing for people like me.. All the best.

  4. My husband lost his arm to the shoulder. Are these a possibility for him? He has had the same prosthesis for 37 years because of cost.

  5. Hello,
    I have a daughter who has one finger. She has seen on the internet hand and would love to have one. Only handmade for someone who has no fingers. Is there a possibility that someone can customize the file for her. There is a 3D scan of her hand made so it might change what is easy.
    Yours sincerely

  6. Acabo de leer un articulo en la revista city energy en Chile, se me llena el corazón con la forma como desarrollo su proyecto, sus objetivos, los logros y el tiempo invertido. Me queda claro que con perseverancia y su objetivo, a logrado su fuerza. No tengo impresora, ni grandes recursos, solo cuento con mis manos y mi creatividad. Nose como pero quiero ayudar, soy Diseñadora industrial, mi correo personal

  7. Hi there-my new born is due in April and I’ve learned he will not have a left hand. There is no limb difference otherwise, he has everything up to his wrist but I’ve been advised that the sooner you introduce children to prosthetics the better. Is there a size available for children 6 month olds? Additionally we don’t have a 3D printer. Is there a way we can order one? Thank you so much and this is amazing!!!

    • Hello! Congratulations on your baby!

      We do not recommend putting these on children under the age of 3 as they have some very small parts that can be choking hazards for younger children who put everything in their mouths!

      You will want to work with a hand specialist or prosthetist who specializes in babies and toddlers and then when he is old enough to try a 3D printed hand – we can certainly help you!

  8. Hola quisiera saber si uds pueden mandarme los archivos de los diseños para imprimir una mano derecha para una mujer de 41 años, es delgada y bajita.
    Desde ya muchas gracias.

    • Hola! Tenemos voluntarios que puedan ayudar a determinar el tamaño. Por favor llene nuestro formulario y nuestro matcher le ayudará!

      La forma es aquí:

  9. Hi there, I’ve trying to make a hand for some time now, but ran into a few problems. There seems to be multiple variations of the gauntlets; where can I get access to the gauntlet with the slits for the velcro as well as the twisting type tensioner mounting?

  10. Hello, I am in your database download images seem to be is incomplete, I am very urgently need to know the method of making 3 d prosthetics, I come from China, this technology is not here, I’d like to cooperate with you, and popularized in China, looking forward to cooperating with you!

  11. Hi guys, yesterday a man of 35 years wrote me to my email asking for my help , he told me he had lost an arm , he is Cuban and I wondered if there would be someone to help you , your email is Thanks for your attention.

  12. Hi everybody,
    Sorry for posting this here but I didn’t found any user forum or so. I am having issues printing the gauntlet for the cyborg beast hand :
    In fact, the contact with the printer plate is too small and is not flat, and the printing always ends up as a big mess. Also, at some point, the printer tries to print in a point of space corresponding to the gauntlet tips, and it’s the least to say that it doesn’t really work. I’ve tried to rotate the 3d model so the gauntlet tips touch the printer’s plate, but yet the surface contact is still too small, and the printer starts printing wires that detach from the model.
    Do anybody ahad issues with it too ? Or are you all succeeding in printing it without any problem.
    I am thinking of printing this modified gautlet instead :
    Or maybe flattening the original model by myslef.
    Thanks for your help,

  13. Hi Jen, thanks for your answer. I’ve just sent the mail.

  14. Hello ,
    I printed the cyborg beast and the gauntlet does not have a place for the tendons to be inserted, also the Instruction Manual is not opening. Is there a way I could get the Instruction manual for the Cyborg Beast to be sent to my email or access it in any other way because I tried multiple times to open it but failed. It says this “This XML file does not appear to have any style information associated with it. The document tree is shown below.

    The specified bucket does not exist


  15. The project is very good and to become more comfortable and not hurt the boy’s hand and I think a glove with specific material and whistled his hand would be an idea to be considered.

    • We now use medical grade foam where it is available but some people are also creating other types of padding!

  16. What about a soft silicon like substance to help in pain and adjustment? Or maybe make it longer in the arm to increase the strong and stability of arm?

    • There have been many improvements since this first design! Please visit the Google+ community or our forums! A lot of volunteers in there to help!

  17. Hi there,
    First of all thank you so much for doing such a noble work. I am a senior Electrical and Computer Engineering students and fr my senior design project I am working on a EMG Controlled Forearm Prosthesis. I would like to use this design for the actual hand, and my question is if is possible to fit servo motors inside the hand to actuate the tendon lines? I would also love to shared my project with this community so more people can be benefited by this technology. Email me at

    • Thank you so much!

      Best place to find out about that would be in the forums but you are always welcome to take the design and “make it work” and we just ask that if you use it for part of your final device, that you give credit back to the designers and community!

      Thank you!!
