Japanese Fantasy Box

One student wanted to 3D print a diorama based on her trip to Japan. So she printed lanterns with Japanese characters, two dolls, a Shinto gate, and two temples. The temples were found on Thingiverse, while everything else was an original creation.

Caps for Sale Center

So here is the beginning of an ELA-inspired center. A kindergarten teacher is making a "Caps for Sale" center based on the book. The tree, the monkeys, the peddler, and the 16 caps are 3d printed. More pics to follow.

Ruby Tuesday

Installing Ruby Plugins


  This is my first time downloading a plugin for Sketchup, so I hope it works out.  You go to Windows>Extension Warehouse>Lib Fredo 6. This led me to a cat-and-mouse game of downloading extension tools from sketchucation.com.

Teaching Adults

So we are just about to wrap up our first ever semester of teaching adults how to use the 3d printer.  I have learned a lot about the process from doing it.

First off, adults and children alike are equally as amazed when they print out their first object.

Second, people who post to Thingiverse don't really print out their designs often because the resulting objects come out pretty awful.  I can tell you the exact number of times we've had to reprint because people's Thingiverse designs came out wrong: 4.

Third, adults and children alike are equally into painting their finished designs. Makerbot has put out a Replicator that can print in two colors.  Eventually, 3D printing will evolve into a multi-color process, which will eliminate the entire post-printing paint process. I think that will be a loss to 3D printing, because people will lose out on the experience of artistic rendering. 

Badge

I received a badge from the Board of Education for presenting a workshop in 3D printing.

Teaching 3D Printing in the Content Area

So today was my first day teaching adults in the Board of Education.  There were a lot of parallels to teaching children and some marked differences. The similarities were that both adults and students were excited when their 3D models printed out.  The major difference was that everyone wanted to keep learning new things immediately and children usually tune out after awhile.

Course Description:	Teachers will learn the techniques of using a 3D printer. Once they learn how to use the printer, teachers can design curriculum that will instruct students to use the 3D printer to enhance curriculum. Teachers will create a playset of 3D figures based on a learning theme. Then they will write 7-10 lesson plans based on the playset and create a diorama. A journal will be kept by each student to record the experience and add writing to the curriculum

3D Pizza

I was wondering what topic I should tackle this week, and I found this picture online.

Why wouldn't I want to learn how to 3D print a delicious pizza?   So I thought about what this particular pizza entails, and I thought of three main parts: crust, cheese, pepperoni, and mushrooms.

The crust remains the most elusive to me because I am still learning how to create perfect curved edges.   How would I take a shallow cylinder and turn it into believable pizza crust?  Well, I Googled "how to curve edges in sketchup."  You can see for yourself.

There is a way of using the Follow Me and the Rotate tool, but lo and behold, there are plugins to round the edges. I used the Artisan toolbar. You have to download the plugin to get the separate tools. I am going to post about that next, in my post called "Ruby Tuesday."

Here is my finished pizza crust. I'll add some mushrooms and cheese later.

Playing in th Sandbox

From the View > Toolbars menu, select the "Sandbox" toolbar. This toolbar allows you to create different landscapes. The "smoove" tool allows you to create a grid, then select different elevations. This can be used to teach landforms in Social Studies.

Math in 3D Printing

I was asked about applications in math for 3D printing during the Technology Summit, and I looked confused.  I looked confused because so much of the process of 3D printing has math embedded in it.
If you ever need to justify doing 3D printing to an administrator or a visiting guest, please feel free to show them a list of the mathematical principles used during 3D printing.

1. Shapes.  The shapes tool has rectangles, circles, and polygons of any size.
2. Measurement.  You have to set the dimensions of any line, shape, or push/pull.
3. Decimals and Fractions. You can input dimensions in whole numbers, decimals, or fractions.
4. Units of Measure.  Are you working in millimeters or inches?
5.Transformations. The rotation and scale tools help you transform your objects.
6. Points and Lines.
7. 3D Shapes.  Spheres, prisms of all polygons, cones, and cylinders.
8. Measuring Tools.  There are virtual tape measures and protractors to use.
9. Coordinate grids.  There is an X, Y, and Z axis. This is a real-world application of coordinate planes.  
10. Radius.  It is important that students understand that a radius is only half the diameter of a circle, so that printed circles will come out twice as large.

I was going to align the ten content areas to Common Core standards, but it is difficult because some concepts come up earlier than others. SO here are links for all the standards in measurement and data and geometry.

Flowers

So my new idea is to create a flower on Sketchup.  I was going to start with a rose, butI couldn't get the delicate petals down, so I Googled it. Let's see how well this works.

So I tried the flower myself, using a sphere, flattened spheres, and a follow me stem. It turned out OK.  I feel like my daisy is missing a few petals.

Technology Summit

Today was surreal. I got the opportunity to speak to people about 3D printing. What an amazing opportunity for me. 45 minutes really isn't enough time to talk about printing, but I tried! People were interested in knowing more about integrating curriculum with 3D printing, so I will make curriculum a weekly topic.

3D Social Page

I was poking around Reddit and found some developers created a social page for 3D printing. A 3 D printing social network.

It is comprised of some designs from Thingiverse, some from bld3r, and some from other sites.  It makes pretty much everything I've done pale in comparison.

Follow Me

Knowing how to use the Follow Me tool has changed my life.  But more than changing my life, it changed the life of a ten year-old boy we will call "Bacon." Bacon was a fifth grade student in my 3d printing class.  I am calling him Bacon because he loves bacon. He's drawn pictures of himself with bacon and even wrote a bacon poem. Also, because I don't want some Internet crazy looking up his real name. I did one lesson on using the follow me tool to create a sphere. Make-a-Sphere-in-SketchUp. I showed the students how to do it, and boy, I never imagined what the result would be.  Bacon took that piece of information and ran with it. He started making cones, hexagonal prisms, all sorts of clever things. It was one of those incredible moments for me where I really felt like someone learned something from me.I really love the hat though.  He started with a circle, then did the follow me along the circle's edge to make a donut.  Then push/pull upward to make the top part, and push/pull down on the inside to make room for the head. Each hat took about 20 minutes to print because it was tiny.

Coils and Turnarounds

I like to study different techniques at different times. Some depending on the students, others depending on the level of difficulty.  So over the past month, I've been considering how to make coils and round-edged objects.  How did I learn?  Tutorials and trial and error.  I started with WikiHow.  It is my go-to tool for 3d printing.  If I want to learn something, I start with WikiHow. Design a Rope Coil.

Then I watched a YouTube video but I got stuck for hours on using the rotation tool.  I'll never get those hours back!  But it is an interesting viewing.

Depth Viewing

I'm a fan of early 3D movies from the 1950s as well as a fan of 3D printing, so my inspiration for this blog came from some old advertisements for 3D glasses. I will be posting weekly about new techniques about 3D printing.
