Making and More Making…in Art!

I had a couple of my design students ask me about making something for themselves that was wearable. It has stuck in my mind for a couple weeks, and so this week my senior Art students are going to be taking on a new challenge, something we've never done before.

I stumbled upon a massive category of things on Thingiverse a couple weeks ago, and was inspired to present this challenge to my students:

"How can we use 3D technology to design our own jewelry?" 

There are literally thousands of things on Thingiverse tagged with jewelry. It's amazing! I immediately downloaded an amazing Mayan inspired Lotus flower pendant and printed it. It was a big hit!

Design Process in Art
On Monday I'm going to ask students the over arching essential question, and then I'll ask students, "So, what do we need to know and what do we need to do?" And the design process begins!

First step is for students to discover and explore the challenge. They will seek out inspiration, develop a plan to get started, define who might be a possible audience of their work, seek out a team of people to work with (provided by me, or sought out by students), and then come back to share what they know

Will they each want to design something unique, yet cohesive with each other's pieces? Will their pieces and their processes be different from each other, but will come back periodically to get feedback from each other, and help each other? At this point, I just don't know. I know that I will need to engineer some pre set opportunities for feedback and consultation

Connecting with Experts
For those of you that have read some of my blog posts before, you'll know that connecting to experts is essential to the design process. I'm very fortunate to have my cousin help us. He's a student and very accomplished jewelry designer. I've already been inspired by his work, and am excited to have my students look at how they are going to share and display their work. It might be through a photoshoot with media students and student models, or it might be through a product photo shoot with some student designed props.

We are going to be using the hashtags #clhsdesign, #clhsmake, #make and #buildtothink during this project. Follow our progress, tweet us back, and join our journey!

Personal Design Challenge

Last week I found myself looking for a solution to hang up student artwork in our art display case. What came from this was a perfect example of a design project that I am now going to use in my class.

Who said necessity is the mother of invention? 

The Problem
I needed to hang artwork on some glass display shelves. These shelves are perfect for placing objects on, but not great for displaying student art work on various types of paper. The question I wanted to solve was, "How can I create hanging clippy things for student art work?"

In this step I took a look at the shelves, measured the shelf thickness, and thought about some of the qualities in a clip that I would like. It needed to be reusable and it needed to have enough tension in the clip part to hold a single piece of paper. One other design feature that it needed to possess is that it wouldn't distract from the purpose of the clip: displaying artwork.

I checked out Thingiverse and found several paper clip designs, and took note of a couple that used a curved shape to the clip to keep tension.

Generating Ideas
This is where the pen hit the paper. I took my measurements of the shelf thickness, and in a few minutes, came up with a few sketches of what I thought would make a decent clip.

My go to design software is Sketchup. Its free and is amazingly robust for 3D modelling. I created a simple rectangle, and then used the pencil tool and the arc tool to create a 2D outline. I decided a thickness of 20mm would be about right. The colour I chose for the clip was 'white' to help the clip blend in with most paper we use in art class.

Prototyping and more Protoyping
From Sketchup I exported my model to and .STL file. Having an .STL file plugin is essential to making this process work, and its dead simple. Find out how to here.  I warmed up the Makerbot, fed in some white filament, and waiting 26 minutes for a single clip to be printed.

The tension on the paper wasn't up to snuff with the first design, so I had to beef up the curved part of the design. 20 minutes later the new design was tested and worked awesome!

Mass Production?
I setup the Makerbot to print as many of these clips as possible on the platform. Turns out 28 of these bad boys can fit on the bed at once. I know more could have fit if I had positioned them differently. 9 hours and a few minutes later, the clips where done!

Students came in the next morning to see that my clips were all done and asked about the time it took to print. Comments like," wow, that took forever," and, "why didn't you just buy them" came up. All valid points. I responded by telling them that I might have found something at Staples or another store, but the clip would not have been a perfect fit for the shelf. I could have also ordered them online, but that would take days or weeks. I have perfectly custom clips in 9 hours. No manufacturing costs, no molds to have made. The manufacturing chain that would normally take weeks for a product like this is now extremely short!

Connecting Students to Design Problems
While 3D printing is amazing, and can be a solution to many design problems, let me be very clear that 3D printing is not, and should not, be the be all, end all, of your program. 3D printing takes a lot of time! Teachers will find themselves with hours of backlogged printing to do (believe me, I've been there!) The focus of my program is for students to take on design challenges, to solve problems and do it with access to many different tools. DO NOT GET BURNED by sinking your entire class into a 3D printing project. My students will not be told they have to 3D print a solution to their design challenge. They can use hand tools, cardboard, exacto knives, the machines in the shop, our laser cutter, etc. to prototype and make their designs a reality.

The design challenge I am now posing to my students is:

"How can we design something that solves a household problem for someone in our life?"

The challenge is huge and overwhelming and yet simple all at the same time. I have purposely setup the challenge so students create something for another person on purpose (check out my post on the Wikiseat Project). I can't wait to see what things my students come up with!

Sharing Designs and Knowledge
Openness is very important when designing. Great designs that are shared can be improved upon again and again through community. I have created a CLHS Design account on Thingiverse, and will be posting student projects and files on the site to contribute to the maker community. Stop by in a few weeks after our first projects are online!

If you want to check out the clip design on Thingiverse, I published it for others to see, download, modify and print.

3D Models to iBooks Author

Welcome back everyone! I hope this year is going to be a great one!

This is a quick post. I hope.

The Inspiration
After spending an amazing week in San Diego at the Apple Distinguished Educators Global Summit I really wanted to use iBooks Author as a tool for students to document and share their learning. It's so much more engaging and interactive than other methods.  

The power of the software is that students are now the authors of their own content and have a HUGE amount of flexibility in what that looks like. The finished products will also serve as exemplars for future students in my multimedia class. 

The Classroom Need
We use Sketchup a LOT in my Multimedia a Design Studies class, and I've always wanted students to have a way of sharing their models in a meaningful way. We usually use screen shots from Sketchup to share our models, but iBooks author has blown me away. 

Full disclosure, this is not a new process,  iBooks author has always handled 3D files call .dae files, but what's awesome for my class is figuring out that Sketchup can easily export these files. This is also not new but I'm excited because it's new to me!

The WorkFlow
I tried it today with a low poly mammoth model from Thingiverse . To import it into Sketchup you need an STL importer plugin which can be downloaded from Trimble's website. Installation is a breeze from the Preferences menu. 

From Sketchup I exported the mammoth files to a .dae file that iBooks Author likes. 

I then dropped in a 3D Widget into my test iBook and I chose the mammoth.dae file and it worked great! The 3D model was fully interactive in Preview mode in iBooks Author!

Uses in Other Classes and Hiccups

I see this being very useful in many classes, not just Multimedia and Design. Students could access any Thingiverse .stl models, and design immersive 3D environments in Sketchup for say, a unit on ancient Greece, illustrating the life and times of Greek civilization. These environments could then be exported as a .dae file and brought into a iBook as part of their project. The pros of having so many 3D files at the fingertips of students on Thingiverse or even the Sketchup Warehouse is that they don't necessary have to spend a ton of time with modelling it themselves, and can focus on the content and outcomes in the curriculum and analyzing how life in an ancient time might have been like. 
For my class where understanding, creating and presenting 3D objects is in the curriculum, we will focus on construction in Sketchup.

One thing I would caution is using models with a large polygon count. You might find that complex models with a lot of curves, and bumps will take a long time to import into Sketchup, or may even crash Sketchup. This temple took about 15 seconds to import for example. The Gnome model was so complex I had to force quit Sketchup because there were just too many polygons making up his body. 

There are ways to smooth models before importing them, but that's another post on its own. 


I'm excited to see how my students will use this workflow to share their learning of 3D modelling techniques with iBooks Author.

All the best everyone!
