Hi Parents!You certainly know the saying I used in the title. It is true that when somebody look at you with a big sincere smile, the reaction is 99% of the time to reply with another smile. Those who know how to use their smile, are more successful than those who don’t…or those who can’t.
Here is an example of one way to solve that problem using a 3D printer. Dental 3D printing is growing rapidly. In a study they just made, guys from TMR (Transparency Market Research) forecast a 17.5% annual growth for the next 6 years in that market.
3D PRINTED MASS PRODUCTION
I found an excellent example to illustrate that point: Smile Direct Club. This company just partnered with HP to set up a huge facility. They will use 49 3D Multi Jet Fusion in order to print up to 20 millions aligners per year (more than 50,000 per day!). This time, for sure, we can talk about 3D printed mass production. This company has already served about half a million people. The growth they forecast in their market will be even more than the forecast from TMR. Good for them!As you can see, things are moving fast. New markets will pop up everywhere while some of the old ways to do business will vanish. The winners will be those who can understand new challenges faster, learn new skills faster and set up new solutions for problems they never had before.
And with a bright smile as a cherry on the cake, they will be even more persuasive.Have a great day!
It’s inevitable. No matter how “awesome cool” a class may be, there’s bound to be a few stragglers who are unable to keep up with the other students. I think most teachers understand the mild sense of angst I feel when I come across a student who just seems lost on the most basic steps, taught just a few lessons ago. What happened? Was I not clear enough? Am I teaching too quickly? How can I get this student back in the game? Here’s what I try to do to avoid this situation, before and during the time it happens.
During the first class of each course, I present the slide below, strongly recommending they do this homework at the beginning in order to avoid being stuck at a later stage. While 3D printing is a powerful tool to make virtually anything you have in mind, it’s a necessary pre-condition that you have something in mind in the first place. Most times, people don’t get hit with inspiration; it might or might not come. When it doesn’t strike, you need time to think about it or you need to actively look for it. Hence, this is why I set this goal at the very beginning.
Following from this, my overall approach is to focus on teaching the 3D modeling tools during the first half of the course, creating my Starter Kit models (more on that in future blogs). By the middle of the course, students should be able to use the tools that they learn to begin to create their own models. This is when it becomes clear who followed my recommendation from the first class and who did not.
So for those who didn’t come up with their own models, I find designs that I think they should be able to do, based on the tools learned so far. For example, after teaching the tools used to make a table and a ring in SketchUp, I challenge them to create any of the following items.
I hope that applying the tools that they just learned to make alternative versions of the Starter Kit models will boost their confidence in their CAD skills. I would present these types of challenges with every class because, in my experience, quite a few students simply don’t know what to do.
Inspiration can be tricky. Personally, I don’t like force-feeding students because I prefer to treat them as adults. I would tell them to create any of the challenge designs before the end of class, but there is no penalty if they don’t. For the students that still say no to my challenges, I resort to my secret weapon: toilet humor.
At a recent lesson covering how to make a cup in SketchUp, one student finally got inspired to create her own version of the poop emoji cup. I think she got a good grasp of SketchUp’s Follow Me tool now!

At a handful of schools and maker spaces in Hong Kong, I teach a paid, after school class for students interested in the STEAM subjects. The class is quite popular. In the most recent school term, 65 students applied for 36 seats. I guess I must be doing something that has really struck a chord with these students. So who are they?
All students range from 8 to 15 but quite a few parents have come to me asking if their own five or six year old child can learn 3D modeling for 3D printing. The short answer is yes. But there are a few reasons why I think they should wait until they are eight or older. First, working in 3D space can be a challenge, even for adults. It’s why I always teach Navigation in the first lesson. Looking at a flat, 2D computer screen, we are conditioned to see only what’s in front of our eyes and little else. We forget that all six sides of the model also need to fit into its overall structure. And because we are passively using a 2D point of view, the model looks intact when in fact it simply isn’t.
I’ve seen quite a few student models with “floaters,” or parts, such as a star or some text, that should be attached to another part of the model, but is hanging freely in 3D space. In all cases, these floaters are clearly part of the overall model, but because they forgot to take the two seconds to orbit around their model for a quick check, it’s simply incomplete. (And when they discover this issue, it’s usually time to catch the school bus!) Depending on their numbers, floaters are relatively easy to fix. But it gives you an idea of the students’ abilities.
Another reason why I think children should start 3D modeling at age 8 or older is because of mouse control. Perhaps this is my own shortcoming as a teacher, but I don’t use iPads to teach 3D modeling. I prefer a cursor on a laptop because it is far more exact, while you can also take advantage of the shortcuts available from a full keyboard. Should I consider a pen on an iPad? This is a fair question, but it also means there should be enough 3D modeling software available, which are fewer than for laptops. Maybe one day in the future, but not now.
The one 3D model that I always start my lessons with, after Navigation, is a simple Table. As simple as this model is, you will be surprised how many students cannot get the legs to line up with the corners of the table top. I think only about 20% of the students were able to get it on their first try. Why is this? An arts teacher once told me young children are not good at measurements. I guess children are still developing their sense of spatial intelligence. With a mouse/cursor, I am hoping this tool can give the children a way to develop this sense. Even if they are still developing their spatial sense, it’s important a tool is available to help in the development.
In the future, I suspect 3D holograms will replace the mouse for 3D modeling. But that is another story altogether.
More to come!
PART I: THE ORIGINAL IDEA OF A 6 YEARS OLD BOY.
On April 26, 2016 I published an article about some discussions my son and I had frequently about the Moon and Mars and how we could use a 3D printer there (if you can read Moliere’s language, french, here is the link to it). The main subject was to, one day, use a 3D printer with recycled material made from things that became useless or from raw material directly collected on the surface of the planet or deeper in the crust. Why doing that instead of using new material especially made for the printer? Well, let’s say that because 1 kilo of freight still requires more than 8 kilos of propellant for a little trip to mars, it makes the freight cost quite expansive.
PART II: SCIENCE PROGRESS TOWARD THE REALIZATION OF HIS IDEA
In April 2018, I wrote another article around the same topic: How can we get cheap material to 3D print what we would need once arrived on another planet (As this article is in Shakespeare’s language, it should be easy for you to read it following that link). Researchers in the Canadian University of Calgary had found a way to transform the production of your digestive track into a solid material that will work very well in a SLS 3D printer.
Markus Kayser and his great invention, the Solar Sinter, was in my article too. Using the energy from the sun and the sand from the desert to 3D print objects was genius.
PART III: WE NEVER GOT CLOSER
And the story just got one more chapter thanks to the great work at the Tethers Unlimited Company. These guys created the Refabricator. A few weeks ago, it was delivered to the International Space Station (ISS). The name of the machine speaks by itself. Something useless that was fabricated before can be transformed in raw material to re-fabricate something with it. In the size of a refrigerator, you get together a 3D printer and a recycling machine that can feed directly the printer to re-use, for example, the packaging of the scientific equipment you just got from the delivery boy on his space scooter.
PART IV: THE REFABRICATOR II CAN ALSO 3DPRINT USING CRUSHED ROCKS
Of course the Refabricator II doesn’t exist (yet…). But someday, in one or two years from now, I will write a fourth article about the concretization of an idea my son had when he was about six years old. The title will be “From a little boy’s dream to reality”. He will be reassured that having creative ideas is a good thing. Great ideas rarely comes from following the main road.
I encourage you all to foster the creativity of your kids and discuss any topics they find interesting to them, even the craziest ones. It will be good for them and for us, parents.

After sharing with you my Lessons Learned after Teaching almost 200 Kids 3D Modeling for 3D Printing in my earlier blog, I now want to do two things:
Cubing from writing
But let’s start with the questions that I need to ask. Writers and journalists commonly practice various forms of “cubing,” which, aside from being a coincidentally 3D concept, can help me work through the tasks mentioned above. So here are the questions I want to address in the coming months based on these six basic aspects.
Who are the students involved? How young can they be? Do they need to have a special skill set, such as good math skills, to learn 3D modeling? Should they have a certain type of proclivity, such as a love for science? Should they be inquisitive? Does extraversion matter? Can they work in a team with their peers?
Who is a suitable teacher to train kids 3D modeling for 3D printing? (Am I a suitable teacher?!) What should their skill set be? Do they need a STEAM background? Do they need an art background?
Which 3D modeling software should we teach? Should we differentiate based on the students’ age? Can we teach other modeling software at the same time? Is it worth teaching how to use slicing software? Which one or ones?
Does the school have a Maker Space, or something close to it? Does the space provide the sufficient IT infrastructure? What brand 3D printer(s) do they have? How are the laptops? Can they properly run the needed 3D modeling and 3D slicing software? What about the virtual classroom?
How often can we run 3D printing classes? How long should each class be? Are there benefits to weekend sessions? What about school holidays? What about during the regular class sessions as opposed to after school?
Do you really need to ask?! Because we love 3D printing! But we should ask: how can we get the kids just as excited about it?
This is the million-dollar question. How exactly should we teach 3D modeling for 3D printing to kids? How fast can we deliver the information? How much can they absorb in a given amount of time? How useful is repeating the same exercises? Would they be able to apply what they learned quickly? How can we direct them to the more practical applications of 3D printing, especially when most desktop 3D printers just print plastic? How can we sustain their interest?
OK let’s look at the answers in the coming months! If you want to add your own questions, feel free to comment below!
