It's my pleasure to empower these kids & see their creativity & skills grow so fast!<br />
<br />
After teaching 6 sessions using Blender, I've switched to TinkerCAD. <br />
<br />
Blender =<br />
More powerful (mesh-level edits, extrusion)<br />
Harder to learn<br />
Requires real computer to install<br />
<br />
TinkerCAD =<br />
Less powerful (missing mesh-level edits)<br />
Far easier to learn<br />
Runs on Chromebooks / browser-only<br />

<br />
At the end, each kid gets a real 3D print of their personal design project (which I print in my garage.)<br />
<br />
The kids are 5th-7th graders, in nearby schools (both public & private), so I can share my skills & passion with the wider community.<br />
<br />
Here are some of their designs. They designed these after only 5 sessions of 90 minutes each.<br />
<br />
Kids are learning machines that humble adults. <br />
<br />
I'm so proud of these kids and so happy to be teaching them. So many great designs and so much love!<br />

<br />
Designs are done in Blender, the most powerful open-source, free, cross-platform 3D Design tool AFAIK... Yes, TinkerCAD is getting more popular lately, but it's just not as powerful IMO, & kids can learn either one if given the right support. <br />

<br />If your school wants me to come help, I'd be glad, so long as you're nearby (Santa Clara, CA).<br />
If you want to start a similar program in your school, I can send you the lesson plans that I've evolved through these sessions.<br />

Cookie Cutters!</div>
<div class="separator" style="clear: both; text-align: center;">
<br /></div>
<div class="separator" style="clear: both; text-align: left;">
My wife wanted to make some cookies for our son's birthday party. So, I made a custom design in 3D (CAD/blender), & printed it on the MakerBot. It worked out well.</div>
<div class="separator" style="clear: both; text-align: left;">
<br /></div>
<div class="separator" style="clear: both; text-align: left;">
It's really not too hard. If you want to know what's involved:</div>
<div class="separator" style="clear: both; text-align: left;">
<br /></div>
<div class="separator" style="clear: both; text-align: left;">
1) Make a bezier curve in CAD, & keep extending it & tweaking it until you think it looks right. </div>
<div class="separator" style="clear: both; text-align: left;">
<br /></div>
<div class="separator" style="clear: both; text-align: left;">
2) You can often bring external 2D art from google searches into your CAD program, & then draw your 3D stuff right on top. (Tracing as a shortcut!)</div>
<div class="separator" style="clear: both; text-align: left;">
<br /></div>
<div class="separator" style="clear: both; text-align: left;">
3) Then, extrude your curve to give it depth for cutting</div>
<div class="separator" style="clear: both; text-align: left;">
<br /></div>
<div class="separator" style="clear: both; text-align: left;">
4) Add a rim for hands to press against, which also gives the piece more structural integrity. Leave a hole in the center to let the baker push the dough out from the cutter.</div>

<P>We made some Halloween themed 3D prints lately. Here's our favorite of the batch, a nice large pumpkin (~4 inches diameter).
</P>
<P>I enjoy the dual color capabilities, which allows us to create a part like this with 2 high contrast colors to really make features pop.

<P>In the process, I learned how to reliably print multiples at one shot. This way, I can kickoff the process, go run errands, & come back to 20 little toys all at once. I then bring them into school when I pickup the kids, to hand out & spread the awareness of this new tool, along with some toys & joy.</P>

It was hard to get a plunger around the drain, as the drain was just too close to the sink's wall. The plunger just didn't have enough room to get around that drain!</P>
<p>Here's where I love the MakerBot most. It really opens up the "solution space" to any problem you face.</P>
<P>It's got a spherical bottom, to get flush with the sink bottom. It's got a flat top, to seal against the plunger. And, it has a hole slanted from bottom to top, to move the drain hole further from the wall, where the plunger can get to it.</p>
<div class="separator" style="clear: both; text-align: center;">
<a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEjIZv1XJ9awUJZ8HTr_p0K_Q1K8Rppg3L-w5lsnlV848D9lgdL7DKDmsXXlZI7GxX1Flkl8CriCewskhHHHyZDtoWYkFZ1YF1eABW235VGEvmI9cAkM729Rouy_ZVYHkKcvnQ8ldSAsKDx3/s1600/IMG_6438.JPG" imageanchor="1" style="clear:left; float:left;margin-right:1em; margin-bottom:1em"><img border="0" height="240" width="320" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEjIZv1XJ9awUJZ8HTr_p0K_Q1K8Rppg3L-w5lsnlV848D9lgdL7DKDmsXXlZI7GxX1Flkl8CriCewskhHHHyZDtoWYkFZ1YF1eABW235VGEvmI9cAkM729Rouy_ZVYHkKcvnQ8ldSAsKDx3/s320/IMG_6438.JPG" /></a></div>
<P>So, I simply designed, & printed a simple adapter, to move the drain opening out a few inches, to let my plunger do it's work.</P>
<div class="separator" style="clear: both; text-align: center;">
<a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEh3Su5lXZv5Kpy9_d-krofPUP2oQMIOHcqo0Knp5EM7StQWoBhU43kAQtiQiKVZqeTH6lq5Z9Mm7yHrc17-LIH5IM7S4opS4ESY4Qz3_h91okW1v0BOoOza6BWn2raxHxUIIygjlqIi3IKc/s1600/IMG_6439.JPG" imageanchor="1" style="clear:left; float:left;margin-right:1em; margin-bottom:1em"><img border="0" height="240" width="320" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEh3Su5lXZv5Kpy9_d-krofPUP2oQMIOHcqo0Knp5EM7StQWoBhU43kAQtiQiKVZqeTH6lq5Z9Mm7yHrc17-LIH5IM7S4opS4ESY4Qz3_h91okW1v0BOoOza6BWn2raxHxUIIygjlqIi3IKc/s320/IMG_6439.JPG" /></a></div>
<P>IT WORKED! I can now keep this little plastic adapter with the plunger in the garage, for next time the sink gets clogged. It's good to use the MakerBot not just for fun, but to empower yourself to fix things around the house in new ways.</p>

But, those hooks are a pain to install. There's no way to just drill them in like a screw.</P>
<P>So, naturally, let's just build an adapter, so you can connect your cordless drill to the hook & install these so much easier.</P>
<P>Here's the prototype. It took a few iterations before I got it to fit right. But, it does in fact let me drill it in.</P>

<P>Now, this plastic 3D printer is great for iterations & prototyping, and this verified the solution. But, we'd never use a plastic drill bit attachment, as it'd fracture at high speed & stress. But, this final plastic prototype could then act as a mold, to then mass produce these in any suitable metal for use & sale.</P>

You can see her stuff at <a href="http://frazicake.wordpress.com/">http://frazicake.wordpress.com</a> To make the cakes stand up, she needs to use dowels (sticks). But, it's trouble getting those sticks to stand up.</p>
<p>So, I designed & printed some simple adapters to allow the dowels to fit into a shaft just the right size, which can then be screwed into a platform.</p>

<p>The first iteration worked just fine! The fit was snug.</p>
<p>So, now, just copy the design into an array & print a set of 15 in one shot!</p>

<P>Doh! The plastic got stuck in the pipes! No more prints for a bit.
</p>
<P>You might see some of the red ABS plastic stuck in this part. It's called the "Thermal Barrier" and it fits above the hot nozzles that squirt out the plastic, and below the stepper motors that feed the filament into the nozzle.</P>

<p>Here's a bottom's up view, with the nozzle removed, where you can see the red plastic stuck up in there :(</p>
<p>So, what to do? Take it all apart & soak this in an acetone bath. ABS plastic dissolves in a few hours in acetone, or at least gets soft enough to clean out that gunk easier.</P>

<P>Success! It took patience in taking it apart, cleaning it, reassembling it, and calibrating the sensitive leveling all over again. But, it's worth it to be back on-line & printing again!</p>

<p>I printed a simple spiral using the golden ratio / <a href="http://en.wikipedia.org/wiki/Fibonacci_number">fibonacci sequence</a>. If you haven't seen Donal Duck's Mathematics by Disney, I highly recommend you pull up your kids & spend 8 minutes here: <a href="http://www.youtube.com/watch?v=YVODhFLe0mw">http://www.youtube.com/watch?v=YVODhFLe0mw</a>.</P>
<p>For those curious about MakerBot limitations, notice how the bottom is peeling off the platform. This is caused by cooling/contraction of the bottom as the top, hot printing still is ongoing. This is in spite of the ABS+acetone bonding layer which you can see, is still trying (unsuccessfully) to pull the bottom down, leaving strands.</p>

<p>The first dragon came out "ok" for 20 minutes worth of design by an engineer who's a very lousy artist.</p>

<p>It's nice to see it as it prints, building one layer at a time. As it builds the wings, it almost looks like it's tickling the part as it prints it.</p>

<p>Sadly, this is very common.</P>
<p>We intend to print a nice part, but it ends up looking like spaghetti!</P>
<p>What happens is, if the bottom of the part slips from the position on the platform, the printing on top will just print into open space, and string along the plastic like spaghetti.</P>
<P>Every mistake is an opportunity to learn, and we're doing lots of this mistake+learn here with the MakerBot.</P>
<p>What we've found works well to avoid this spaghetti is:</P>
<ul>
<li>Ensure the platform is level & close to the tips. Calibrated the platform every day, and do it hot (as cold/hot have different positions, & it prints hot, so you must calibrate hot)</li>
<li>Once the platform is close, then, use ABS+acetone in a slurry, and apply a little of this to the platform to create a more adhesive bonding layer to prevent new parts from moving while printing</li>
<li>Print a "raft" or other wider bottom material in your design, so that it has a wider base, which is inherently much more stable to prevent motion later in the print</li>

<p>My son continues to learn the power of iterative design. (Imagine, design, build, evaluate/learn, redesign). And, we love how the MakerBot shortens the iteration from weeks to hours. Here, he designed a more complex "tower" for his monopoly upgrades.</P>

Shirley Lin is the facilitator & the best networking catalyst I've ever worked with. So, I made this little medal for her & the group.

<p>My kids' school mascot is a dragon, so I made a crude first attempt at making one from scratch. A few spheres, stretched, rotated, scaled, attached, & some tweaked cubes stretched for wings.</p>

<p>Ever have a looooong Monopoly game? Where everyone keeps getting more money & nobody loses? My son decided to build a "skyscraper upgrade" which is 10x the cost & rent of a hotel, to help escalate the game. He designed this in blender/CAD & has 3 iterations already on it.</P>
<p>Iterations are key in engineering & development of all sorts. My son & I are coming along great with fast iterations (imagine, design, build, learn, plan a revision, & redesign). The faster the iteration, the better all around, not to mention the more satisfying to the builders! He made this tower/skyscraper himself, & on each print, figures out what he wants to do better.</p>

<P>Then, the next week was "Early Adopter Pain" in it's most classic form</P>
<ul><li>The motherboard fried. 100% dead. The MakerBot team shipped me a new one quickly, thankfully.</li>
<li>I followed the motherboard replacement specs carefully, but they were rather fresh/new</li>
<li>I found ways to fix the loud banging noises on homing, & am glad.</li>
<li>After much debugging & bad prints, I discovered, through classical "Doh!" bonehead troubleshooting, that I connected the Z-Min cable to the Z-Max connection on the board.</li>
<li>So, after 3 days up, 7 days down, I'm back online & dancing again!</li>
</ul>
<p>
Early adopters have inherent pain. We need to be forgiving, knowing that there's a fine line between "leading edge" and "bleeding edge". I've been very lucky, as an early adopter on the Prius (2004), and Solar Panels (2007), and Linux on a laptop (2003) with ZERO trouble, so it's expected that my roll of the "Early Adopter Pain Dice" should come up snake-eyes now.

<P>Withing 24 hours from getting the tool, my 8 year old son was able to imagine, design, & print, an idea of his own, 100% by himself. Quite impressive for both the tool & the kid!</P>
<div style="clear:both"></div>
<p>Here it is: A snowman! He simply made 3 spheres, of different sizes, & positioned them on top of each other. OK, I helped him just a little by suggesting he add some cross bars at the bottom for stability, but he drew them in CAD by himself.</p>

<p>My daughter requested a medal with her name on it, and it was easy to add this to the design. She's so proud to be part of this process, at just age 5.5. She also told me to get more colors than just boring "black & white", so I let her pick out some more colors to order. In a few days, we'll have purple, red, & green delivered from the good small company in Brooklyn (<a href="http://makerbot.com">MakerBot.com</a>) that's bringing this open-source tool to the early adopters.</P>john v schmitthttp://www.blogger.com/profile/10790628625391128720noreply@blogger.com1tag:blogger.com,1999:blog-3109608382691255793.post-67497238234836104622012-08-22T17:30:00.002-07:002012-08-22T17:30:36.479-07:00Super Cool<div class="separator" style="clear: both; text-align: center;">

<P>Did I mean to print spaghetti? Nope! So, the first thing we printed was a calibration item, to check if everything was setup correctly. Well, of course, it wasn't! This item is for sure for "early adopters", and we knew it when we bought it. It takes debugging, patience, but the rewards are there. And, the online community of early adopters on this tool is amazing, passionate, & very collaborative.</P>
<P>How'd it go so wrong? Why spaghetti? Well, this thing prints layer by layer, and, like so many things, the first layer is the foundation, and if you get that foundation wrong, it's all crud on top. We had to go back to square 1, & calibrate the spacing between the platform & the extruder tips. And, from some online tips, found it's best to cover the sides to keep it warm.</P>

<p>After some adjustments, FIRST PRINT SUCCESSFUL! Here's an image of the "custom medal" that I made. My kids love getting coins from swim class, & medals from school, so I made some custom medals to print for fun & motivation.</P>
<P>I designed the medal using a free 3D CAD tool called <a href="http://www.blender.org">Blender</a>. Like most other CAD tools, it has a rather steep learning curve, but it only took me an hour or so to design this, as I have many years experience in other CAD tools. It also took my 8 year old son about 2 hours to build his first model, since 8 year olds are 110% learning machines!</P>

<p>This is truly exciting for the Schmitt household. It's truly empowering to "Imagine it. Design it. Build it." All in one hour!</P>
<p>Kids? Well they are born into the world in it's current state, & don't appreciate how fast things have improved since their father's day. I was able to explain to my 8 year old son, that just 15 years ago, when I was a mechanical engineer, design-to-reality was a 2-4 week process, costing $2-10k. And, that iterations (build, learn, redesign, rebuild) took 2-4 weeks as well. Now, with this MakerBot, we can do 4 iterations per day, easily! This truly is the future of invention & manufacturing, and I'm very excited!</P>

<p>I'm so glad I made this investment. It reminds me of how "game changing" the first home PC's were in the early 80's.</P>

<p>We just got our <a href="http://www.makerbot.com/">MakerBot Replicator</a> last week, and the whole family is excited to get making things!</p>
<p>
We plan to share:
</p>
<li>A) What this tool can do
<li>B) Tricks/tips about using the tool best (what problems we had & solutions we found)
<li>C) Photos of our designs
</li>
<p>
Most of this will likely be simple designs, that my kids can build, as they gradually learn CAD & the Makerbot. If/when we get "great" designs going, I'll also upload them to <a href=http://thingiverse.com">Thingiverse.com</a>, where there's a great & growing catalog of printable designs from a great community of engineers around the world.
