On June 1st i.materialise participated at TedxKids Brussels. This event brought together people as diverse as Walter Bender (of Sugar Labs), Maarten Lens Fitzgerald (the Founder of Layar), Mark Frauenfelder (Editor of MakeÂ Magazine and Boing Boing), Mark Surman (of the Mozilla Foudation), Gever Tully (of the impecably awesome Tinkering School), theÂ great team of Technology Will Save UsÂ andÂ more inspiring and wonderful people.Â Also in the mix wereÂ Franky and I on behalf of i.materialise. One part of the day was to give a TED style presentation to a group of 450 adults.Â Â
The “TED style presentation” was daunting enough. I mean you”re standing on the same red dot as that mind blowing guy with the windmills. At the same time it does not help that all the other speakers have clearly done this kind of thing beforeÂ and thatÂ everything is being recorded and simulcast. All I wanted was one crappy speaker so that I”d look good. Alas, the presentations were all informative and very well done. Â But,Â the truly terrifying thing about TEDxKids was the kids. You see, the real object of TEDxKids was to teach a group of 56 ten year olds how to be makers(Initially there were going to be 48 childrenÂ but rumor has it that Vladimir Putin intervenedÂ to include someÂ of his children at the last moment). The kids were going to have a day of workshops where they”d learn to solder, make a chair, work with software, DJ and 3D print of course.
The problem is that, the last time I had a sustained conversation with a ten year old was 11 years ago. It was very difficult for us to gauge their level of understanding of the concepts we would explain and show them. We decided to do aÂ workshop where we”d explain 3D printing, let the kids touch and play with a lot ofÂ 3D printed things and then let them do several demonstrations to explain to the class how 3D printing works. At the end of the presentation FrankyÂ would go into Â 3Dtin and the kids could thenÂ 3D model something that we”d 3D print. 3Dtin lets anyone 3D model. We did tests beforehand including asking the kids to play around with 3Dtin and we knew that the kids could use it well. We also brought a full minivan worth of 3D printed things. This let use some great demonstration pieces showing the kids what was possible with 3D printing and how it works. More importantly it let us put several 3D printed things on each of the kids desks so they could touch and play with them during the workshop. We thought this would not only let some learn better but also give them the opportunity to do something andÂ learn should they not be interested in what we were saying.
We bought toothpaste, tortillas, pancakes and glassÂ cutting boards. Teams of kids used them to simulate being a 3DÂ printer with theÂ cutting board beingÂ the build platform and the toothpaste theÂ print head & build materialÂ for example.Â Â This was fun but we were unable toÂ let the kids show us more thingsÂ in the interests of time. We loved watching them 45 minutes soundsÂ like a long time but weÂ easily could have used twice thatÂ amount. Small things such asÂ confusion on how to save a design or log on to the PCs also ate up time. The devil really is in the details with these things.
A greatÂ tool on the day was of course a 3D printer. We had a beautiful Objet 24 printer. We gave two workshops and each time and once the kids were told the Objet was there they mobbed it. They looked fascinated at the UV light and the deposition of material. Having the printer really let kids understand the technology. Interestingly while the kids were very excited about the uses of 3D printing and what they could do with it they were less amazed than adults are. The “suspension of disbelief” was not an element.Â Also, I think that because they are more used to learning new things and their minds are less cluttered by oldÂ conceptsÂ kids take better to the technology than adults. Adults are aÂ slower.
Franky thenÂ talked aboutÂ the 3D modeling tool 3D tin to the kids. This lets anyoneÂ make a 3D model by buildingÂ it up out of blocks.Â He explained some things in 3Dtin that the kids wouldÂ probably not discover by themselves. He also walked them through the practical things in the software such asÂ rotating and extruding. Here Franky would also have liked to give the kids more of a demo and showÂ them how to build more complex things. We did the workshop twice and both times we would have liked to give the kids much more timeÂ to play with 3Dtin.
The kids made lotsÂ and lots of stuff from dream housesÂ to jewels and butterflies. TheyÂ found it easy to work with 3Dtin and were aÂ able to create 3D printable models. Because we had done the test previously we had 3D printed some things already. The pictureÂ at the top of the post shows Retik with his 3D printed glasses. I think itsÂ the single bestÂ explanation of this technology and its potential. Retik is ten and was able to design and make his ownÂ glasses using 3D printing.Â We”ve believed for years now that 3D printing will change the world. TEDxKids Brussels was a lot of fun for us and we met a some great people. But, by far the most valuable thing for us was proofÂ that indeed it will. We”d like to thank the kids so much for showing usÂ we”re on the right track and that with easy to use tools such as the Objet24 and 3Dtin 3D printing will let anyone make anything.
Thank you so much to Jayesh of 3Dtin on all his work on the 3Ditin export and the feautures he built for TedxKids. WeÂ are very greatful to Objet in sending us an Objet 24. Also, we”d like to thank Michael of Objet forÂ driving for ten hours to take us through all the ins and outs of the Objet24. We”d like to thank the facilitators and helpers that set up the room with us and took care of the kids during the day. Thank you so much to the organising staff!
TopÂ 5 tips for a TEDxKids workshop
- The kids are smarter, learn quicker and are more seriousÂ than you think.
- The kids get distracted super easily.
- Change it up. We had the kids move around the room, watch a movie, watch the 3D printer and touch a lot of 3D printed things.
- Don”t worry about “keeping kids in line.” If you are interesting enough you won”t need to.
- Make sure you have no blocking issues such as faulty equipment or unclear instructions, this slows you down.
