“Open Source 3D creation. Free to use for any purpose, forever”. What is that???


What a great statement for a title. Do you know what is it? Read bellow for the answer.


One of the “Creative Tools for the Mind” our kids and us use just got a special reward: the Ub Iwerks Award (Ub Iwerks created, among others, the character of Mickey Mouse). It is given to honor individuals or companies for technical advancements that make a significant impact on the art and industry of animation.
Past recipients of this award include Dr. Ed Catmull for his breakthrough technologies at Pixar, Scott Johnston for his innovative work in Looney Tunes: Back in Action, Digital Domain, Inc. for their groundbreaking innovations in Titanic, and Eric Daniels for the development of the ‘Deep Canvas’ process for Walt Disney’s Tarzan.


This award was given to none other than Ton Roosendaal, the genius creator of Blender. Of course the amazing Blender community of developers, artist and users of almost any age you could imagine made this 3D creation suite what it is. But if it has survive since the 90s and grew up to become one of the most look after software in the 3D animation industry, it is mostly thanks to the leader of the “Blender tribe”, Ton.


Imagine that our kids can learn from 3D modeling to 3D printing and even 2D and 3D animation, Virtual Reality and Augmented Reality without paying anything for the software. Even if a beginner can easily found his way through Blender (especially the last version Blender 2.8), more and more big animation studio use it among their tools. Artists, engineers, scientists, schools and many others use it as well. If it is good for them, it is good for our kids.

Dear parents, the vision we share of a World with proactive, open minded and creative kids just got rewarded.
Have a great day!

3D Creation Apps Recommended for Aspiring Designers

3D Creation Apps Recommended for Aspiring Designers


It is clear now that doing 3D modeling on a computer is a great and beneficial activity for the development of the brain of our kids (very effective for adults as well!).

Autodesk alone in the sky.

Tinkercad main screen

Until recently, Autodesk was somehow alone in the sky with no real competition to challenge its Tinkercad web-based 3D modeling software. And Tinkercad is great. Very intuitive and simple to use. Kids love it. But being unchallenged is not very healthy in the long run. Some real adversity is good to stay sharp and give the best it can.

A real competitor is arriving on the “3D Modeling Software for Kids” market (and it is a big player!)

Many among you will know, and maybe have used, another really powerful software named Solidworks, used mostly by professionals around the globe for more than two decades. Like Fusion 360, it is awesome to do parametric modeling (you create your model following precise steps and parameters like size, shape…). As it is not at all for beginners, kids would have a hard time trying to use it to create a model of their own.

Shape It from Solidworks Apps for Kids

Fortunately, at Solidworks, they worked hard to develop new tools especially for kids. They choose a different path than Autodesk. Instead of a complete software with many tools immediately available right after the child is connected to a web-based software, they developed a cluster of very simple and efficient apps. For example, if you want to create a new model, you launch Shape It. In an instant, you have the ability to model something with mostly a sculpting tool. You have very few options available. It is your imagination and some virtual clay at play. Which is wonderful for beginners. You just have to learn one simple tool to have fun. The interface is very clean with just a few buttons.

Cube Print to the rescue!

And if you are happy with the result, just launch Print it. You have the choice to 3D print it if you have a 3D printer available. If you don’t have it in your backpack, don’t worry, they get you covered! They have a funny surprise for you. You can Cube Print your creation. A regular 2D printer using regular flat sheets of paper is sufficient. Once printed, you just have to cut following the outer line around the model. You use some glue to stick together the faces. And you get a nice cube made of paper with a picture of the model on each face. The front face with the front view of your model, the top face with the top view, and so on. A marvelous idea to use 2D images to see in “3D like”. Your kids will love it.

Which one is the best for your kids?

As a 3D modeling enthusiast, I love them all. But for a complete beginner, I would recommend to start with the SolidWorks Apps for Kids. It will help your kids to be at ease with a 3D model on a screen. They will be much more comfortable to do more advanced models faster than you would have dream of it. Tinkercad would be the natural next step.

Encourage your kids to play with them all. The way to create a model in 3D is different but the goal is the same: allow our children to become creative masters, to think critically, to make mistakes and learn to persevere.

The road will be long for our children and with many bumps along it. If a simple and yet so powerful activity like 3D modeling for 3D printing can help them live an interesting and engaging life and see the world in a more creative way, let’s do it!

P.S.: www.swappsforkid.com has just been released and is at the beta stage of development (the last one before the official release). Try it anyway. It is a good one. I’ll tell you when it will be at full speed and will do a complete review at the same time.

My BIG Plan for 2019


OK I’ve been involved in 3D printing for four years now and so it’s time to take things up a notch with my BIG PLAN for 2019: pass the Fundamentals of Engineering (FE) Exam. What is the FE Exam and why am I taking it? In the USA, the FE exam is typically used by college engineering students as a prerequisite before taking the Professional Engineering (PE) exam in order to be a fully licensed, nationally recognized engineer. But I’m taking the FE exam because it’s a prerequisite for me before I sit for the US Patent Agent exam. What’s the connection to 3D printing? Let me explain!

Since the 1980’s, product designers have been using 3D printing technology to prototype products for their companies. Today, anyone, even kids, can design a product using freely available 3D modeling software, which they can then prototype using extremely affordable 3D printers. But beyond this, kids can also apply to patent their product design! The World Intellectual Property Organization (WIPO) shows how China and the USA lead the world in terms of patent grants with around 400,000 and 300,000 issued respectively in each of the last three years, so I will start with the US Patent Office exam.

If I can pass the FE exam, it will be a great first step to getting a US Patent Agent license. As a Patent Agent, I will be looking forward to helping anyone with a product idea apply for a US patent (including myself of course!). For the young students I have been working with, this will help them in three seriously important ways:

1. Learning from failure. American inventor Thomas Edison once said, “I have not failed. I’ve just found 10,000 ways that won’t work.” During his lifetime, Edison accumulated 2,332 patents worldwide (1,093 in the USA) for his inventions. Obviously, not only did he embrace failing, but he also very likely learned from his failures in order to proceed to the next step. I think learning to cope with failure is a great lesson for young students, a skill they can use throughout their lives. Prototyping their ideas via 3D printing can provide this invaluable training as they work through different design iterations.

An eternal optimist

2. Help on college applications. Obviously, securing a patent will look great on a college application. (In fact, the US Patent Office confirmed to me via email that they have issued patents to minors in the past.) But we also know that securing patents takes a lot of dedication and hard work for the inventor; patents are only granted to truly original ideas and designs. But I would argue that a college application with a series of unsuccessful patent applications could also be just as competitive as a successful application. Why? Because failures are just part of any success story. As Edison also said, “Many of life’s failures are people who did not realize how close they were to success when they gave up.” Show the college admissions board your failures and your ideas to improve on your designs. They will be impressed by your sheer tenacity.

3. College financial assistance. In the start-up world, securing a patent is one of the key ways to locking in investor interest and capital investments. Patents also play a key role securing a licensing deal to earn royalties. In either scenario, there are definitely ways to monetizing your patent. With college tuition costs skyrocketing in the last decades, families need ways to counteract these inflationary forces. Proto-typing and securing a patent could be a seriously viable method to doing so.

Can kids really get a patent? With ever-affordable and accessible 3D printing technology, we certainly have the tools necessary to rapid prototype almost any product idea. Just like how computers were once owned only by huge companies with deep pockets, but can now reside in our own personal smart phones, trends in 3D printing are quickly making it possible for the general public to design for themselves. With kids being more creative than adults, I think it will only be natural to see more patent applications from youngsters and patent grants will follow. Passing the FE Exam this year will help me be part of this massive trend. Wish me luck!

Lessons Learned after Teaching almost 200 Kids 3D Modeling for 3D Printing


One of the biggest perks of teaching is learning from the students. Every time a student gets stuck on an issue from one of his or her own design, it gives me a chance to reinforce my own 3D modeling skills because I am usually looking at a design I’ve never seen before. Some issues are simple to solve, so the solution confirms what I know about the 3D model building process that works. Other issues require using the Undo key multiple times to get back to a position that makes sense to both of us in order for us to move forward again. In both cases, it’s a learning opportunity for me as well as the student.

But more specifically, here are three lessons that I’ve learned teaching almost 200 children, age 8-15, over the last three years 3D modeling for 3D printing.

There’s always another way

Find a balance between “free rein” and “do this”

While it’s true that 3D printing can turn your ideas into reality, you obviously need an idea first. In every first class, I tell the students to come up with three or four of their own ideas, which they can model and 3D print at a future date, while I teach them the tools. But sure enough, some will be scratching their heads when the time comes, unsure about what they can do. Here, depending on the season, for example, Halloween, I will lead them to a dozen or so new modeling ideas. Given the range of ideas, it’s always interesting to see which design they choose based on the complexity level. You can spot the star students here.

Repeating instructions is a necessity, so be patient

These kids are learning to draw in 3D, “graduating” from the 2D world of pencil and paper. I’ve seen adults struggle with it in my other classes, so it’s not exactly a surprise to see children needing more time to move up the 3D learning curve. If you think they understood how to merge a solid with a hole in Tinkercad, think again. And what about that Revolve tool in Fusion? How does that work again? But when they all fully understand the tool, don’t worry; they will let you know, loudly!

The Wonderful Connection between Cooking and 3D Printing

Use cooking as a reference point

I have blogged in the past about “The Wonderful Connection between Cooking and 3D Printing” where I point out that you can build a 3D printable model much like you can cook a dish by following a recipe. But more than this, using cooking as a reference point is very applicable when the children invariably ask to 3D print something they just download off the Internet. “Sorry, no!” I’d say. “I’m teaching you to cook, not to order fast food!” They get it and return to their own designs.

How to implement/promote collaborative learning in the 3D printing classroom


In those careless childhood years, when play is a vital part of development, many an enchanting scenario is dreamt up in the minds of our young ones. What is it that so many children dream of? Even from a young age they start to develop their own distinct personalities and create their own worlds inside their vivid imaginations. Regardless of what the product of those imaginations may be, given the capability to make those imagined creations come to life, what child would not jump at the chance to design their own toy or dreamt up character?

Simple to use Tinkercad

As many of you may have found from reading the various blogs on the 3D Roundhouse website, never has there been another time in history where it’s become so easy for anyone, young or old, to make their ideas a reality, thanks to the magic of 3D printing and simple software like Tinkercad.

Some of those who have been dabbling in 3D printing for a while may be familiar with Modio (http://modio3d.com/), which was later rebranded to Tinkerplay when Autodesk acquired it. Modio was a fun iPad app developed by an independent team, which allowed the user to create an action figure out of a selection of snap fit parts. Sadly this app was canned shortly after Autodesk acquired it, along with a bunch of other promising apps Modio had developed.

Despite this unfortunate series of events, Autodesk at least had the wisdom to include some of those connector parts in Autodesk’s aforementioned 3D design platform Tinkercad.

Tinkercad Connectors

Many of our readers are likely to be aware of Tinkercad through the many tutorials we have on our website, but perhaps you were unaware of these useful Connectors. Let’s take a look at how to get started with these connectors and some useful tips I’ve gained from some projects I did with my 6th and 7th grade students.

On opening a new design session in Tinkercad, we can click on the shapes menu on the right and navigate to Connectors. There are also some pre-designed characters, which utilize the snap connectors, namely a dinosaur and a skeleton. These can be found in the printable kits section. Once selected, they can be printed out and assembled. Students could even mismatch the parts to create some interesting creations.

The key thing to keep in mind when having your students design with connectors is to make sure they lock the components. No matter how many times you tell your students, “Don’t scale the connectors or they won’t snap together” they will more than likely do so, even if not doing so consciously.

Once locked, the components cannot be moved, rotated or grouped. Therefore a good practice would be for the teacher to design a template Tinkercad project with all of the right connectors in the correct positions for the students to then add their own parts to. If any minor tweaks are required you can always unlock the components, keep an eye on the student while they make the changes and then re-lock them when finished.

More complex parts like the torso are best assigned to the more capable students

In our class, we assigned each student a part of the body to work on. I explained to the students that they needed to communicate well in order for this project to work. Unfortunately, one or two students weren’t listening and used only socket connectors on both of their designs. The result, all but two of the parts could fit together to make up the stick man’s upper body. I allowed the students to build the model themselves so they would discover the issue. I believe learning from mistakes is a big part of the students’ learning process and so allowing for failure and building a discussion around it shouldn’t be shied away from.

However I pre-printed some correct parts also so they wouldn’t be so disheartened.

We hope this blog post has inspired you. Have you tried anything similar? Do you plan to try this kind of activity in your classroom? Let us know your thoughts in the comments section.
