• Life after TEDxKids | Ritik Mehta | TEDxKids@Vilnius – YouTube

    This talk was given at a local TEDx event, produced independently of the TED Conferences. TEDxVilnius organizers met Ritik at TEDxKids@Brussels back in 2011. He was their hero since then. During this talk Ritik shares his extraordinary story and leaves everyone in awe.

    Ritik Mehta is 14 – year old who started his fascination with 3D printing back in 2011 at TEDxKids@Brussels. This fascination led him from mastering the technology to understanding its potential and from educating his peers to helping the needy. Since then Ritik helped organise the last 4 editions of TEDxYouth@Flanders and also spoke at one. Besides being active in the 3D printing community and expressing his thoughts on the future of his generation, Ritik helps with Eyes for the World, a charity that brings eye care to needy children in Africa and Asia. He started a commercial venture to sell 3D printed eyewear to fund his ideas for Eyes for the World of 3D printed glasses for the needy.
    As Forbes stated: “Not many people his age can claim an association with a technology as emergent as 3D printing, a non-profit organization, and the phenomenal TEDx, all at once.”

  • 3D printing and digital creation: Ritik Mehta at TEDxYouth@Flanders – YouTube

    Ritik got inspired at TEDxKids@Brussels in 2011 and took up 3D printing as his mission. A year and a half later he wants to share his experiences and insights on 3D printing and digital creation with his fellow digital natives. An interesting talk on how digital creation will impact a generation.

  • Doodle3D Review

    Thursday morning I got envious of @3dhubs for posting the below tweet: 

    Unboxing of the doodle3d wireless print box! #3dprinting http://t.co/GunBy7fLGA
    — 3D Hubs (@3DHubs) November 14, 2013

    I want one too! And that evening when I came home, there it was… a little brown box, slightly smaller than the AppleTV packaging… Opened it up and inside was a white box with bright colours scribbles saying Doodle3D!

    Backing this on Kickstarter was a great experience: tons of feedback and an exciting product and great people. Great fun to see them at Ohm2013 afterwards as well!

    In the words of Ritik:

    The device is a small box which has it’s own Wi-Fi and it’s connected with the printer with the USB cable, and when you’re connected to that Wi-Fi you can draw something and then send it to your printer so u can print from any device which has that Wi-Fi. 

    How it works:

    The Doodle3d works with an HTML5 app that you access by pointing a browser to http://draw.doodle3d.com/It works on all kinds of devices from Desktops to iPhones and tablets.


    Setup is easy: you connect the box to the printer using an USB hub that comes along with it (something to do with USB1.0/USB1.1/USB2.0 stuff). You then power the box and wait till it lights up all green LEDs. Point the browser to http://draw.doodle3d.com/ (it picks up DNS calls to this and points them to the box, provided you use the DHCP-based DNS settings). Then comes the bit where you get a guided tour of the interface and then select your settings:

    • Type of printer
    • Bed size
    • Wall thickness
    • Layer height
    • Print speed
    I found these 5 settings to be the most important one to get the prints coming out nice and clean. Wall thickness helps greatly in the strength of the piece and print speed is also very printer dependant (I lowered mine to 30 on the leapfrog)

    Start Printing:

    Ritik‘s impression on the setup procedure was clearly simpler:

    Once it’s setup it’s quite easy to draw something and print it, it’s just needs to be plugged in and u can start , first u connect to the Wi-Fi then u go to your web browser and go to the link draw.doodle3d.com and u can start drawing.

    Our Opinion:

    I asked Ritik to praise and then be critical:


     It’s nice that you can select how thick you want to print the perimeters so that you don’t print thing that when you take it off the bed it breaks. And then it has some strength.

    Intersecting paths: 

     The software also works with intersecting parts. If you have for example a infinity sign it would go over the sign as we would draw it. It would not do one half and then go to the next half.

    Even more, it allowed for traversals where it would not print, but move to the next bit

    Multiple Devices compatible: 

    Once you print a objet from one of the device’s you can’t print from any other so there’s no interference with the device’s and if you print something but the connection is lost, it’s okay cause it send the file to the box and then it’s being send from your device anymore.

    But at the same time it allows multiple devices to draw stuff and wait for the printer to come online.

    Extrusion control:

    … There’s no such button where you can control the extrusion. So if want to change filament, you can’t do it from the device. so it if they add a extrusion button that would be useful.

    In fact a better printer control panel would be amazing to allow you to fine-tune the printer or home the printer and extrude filament before you print.

    Everything is about Z0

    When it prints, the distance between the bed and the extruder should be perfect, otherwise it would not print properly especially because it’s a one perimeter print. 

    Apparently the whole 3d-printing world revolves around the first print layer, so why would be doodle3d be an exception?


    There are 3 things I find should be added

    • Add .stl : if you could just upload an stl so you can print files that u already have.
    • Add normal shapes : It would be nicer if you get a certain amount of shapes and that you could edit them afterwards.
    • Add .svg : It would be also cool if you could just upload a .svg file and this would be a lot easier if you want accurate drawings.


    Beyond that I would love to have some kind of indication before I print of the size of the doodle… Sometimes I draw a ring, which then prints like a bangle… Great fun, but a grid or measurement would make doodles better life up to the expectations.

    DualExtrusion Doodling

    Wouldn’t it be great if you can print in two colours and take advantage of the dual extruders on most new printers.


    I could not help but wonder if there is a way to hack the Doodle3d to also enable you to dump gcode on the box and use it as a print-server of kinds… But more on that, if I ever get the time to dig into the device!


    All in all a great device to have around for workshops and parties, to quickly show people the power of 3dprinting without having to learn to model anything… A great way for smaller kids to see their creations come out of the screen and into the printer…

    [Please note that this is the first post in which I am taking my son’s help to slowly introduce him to blogging his own opinion on 3d printing and products… I hope you can read past the “cooler” language. If you have a product that needs a teenager’s opinion, don’t hesitate to contact us! Slowly I want to move out of the Editorial role and let Ritik write his own posts here!]

  • 3Dprinting in Education: when? how? why?

    People often ask me at what age children should be confronted with #3DPrinting and where?

    Seeing the interest of my two Deeplets, I decided to introduce more children to 3DPrinting by doing a talk and workshop at TEDxYouth@Flanders 2011 for children aged 11 to 18 years. And even convincing Ritik’s 6th grade teacher to let Ritik do a talk for career day on 3DPrinting (due this Friday). This was before the technology hit Belgian mainstream media and it became acceptable.

    Current convention is to introduce children to 3Dprinting during higher education, but my view is that they should get in touch with this technology a lot earlier. It should be at a stage when their imagination is still wide open and not in a mere design-oriented environment. 3Dprinting is not only about design, it also sparks interest in engineering and software programming.

    As a matter of resources, I can understand that targeting a small set of design students is easier and more effective that addressing all the primary school students, but specialty events like TEDxYouth and local Belgian ikanda, would be ideal platforms to reach out to children.

    There should be a standard package for schools to get involved: a sponsored printer, which could be assembled as part of a class effort and a package of lessons which can help children get started. Websites like tinkercad.com could be great catalysts there to help children grasp the basics of CAD design. All the elements are available separately, but they need to be packaged into one solution for schools, so that they are easily applied. Maybe even do the program with loaner printers, which could stay at the school for 1 month for the children to get acquainted with an option to buy one if the program is well received.

    The idea of building your own printer may not be relevant for too long, since assembled solutions are amply available and it will allow you to focus on the printing rather than the printer. But assembling your own printer does give you insight into the technology and also is a nice way to explain the basics of electronics to kids in a very applied manner.

    One of the hurdles in general acceptance of Additive Manufacturing is the reluctance of the current engineering corps to adopt the technology. It is fine for Rapid Prototyping, which is an outlier process, which is often outsourced. But the moment the tech comes on the work floor, people are skeptical. This needs to be changed in the next generation of engineers, who need to see Additive Manufacturing as an additional tool on the work floor for a much more flexible manufacturing base, not as a threat to their existing way of working.

    We as a generation may not have been able to solve the world’s problems, but that should not prevent us from raising a generation of children who may!
