"The 3D printing industry is expected to exceed $21 billion by 2020. Classrooms are joining in. Kelly Hines' fifth-grade classroom is redesigning a prosthetic hand. Can't buy a drone? Soon, you may be able to print one. You can print robots, math manipulatives, and even parts for a 3D printer. (In fact, Bryan Byer's science classroom in Michigan built their own 3D printer.) What will happen when we can 3D print things from door stoppers to wind turbines to (wait for it) wedding dresses? This past year, my students and I began our journey after I saw the FabLab at Kentucky Country Day School last summer."

"3D printing is a very cool technology that has garnered a lot of attention lately. The additive manufacturing process 3D printers use and the software to create 3D models can be extremely confusing. In an attempt to share some information about the 3D printing process Shapeways created a 2D explainer of 3D printing. Introducing students to the world of 3D printing is a great way to get them excited about manufacturing and design. Students are able to see their ideas and creations come to life before their eyes in a very short period of time. One of the main benefits of 3D printing is the ability to rapidly prototype ideas and designs for anything from fashion accessories to the rocket engines produced by industrial printers at NASA. The Shapeways marketplace gives students and teachers the ability to quickly upload designs and have them printed and shipped within weeks. For classrooms without access to expensive 3D printers, this allows students to get in on the exciting action of 3D printing and modeling."

"You may have heard about all the cool things 3D printers can do. If you're a math teacher, maybe you've thought about letting your students make their own manipulatives or get hands-on in geometry with 3D solids. If you're an economics or business teacher, perhaps you've considered assigning students a project to design, market and sell their own 3D-printed products. Or maybe you're a science teacher interested in exploring 3D models of cells, atoms or DNA with your students. Wait! Slow down. Before you jump into purchasing and integrating this new gadget into your classroom, take a moment to consider the logistics and realities of becoming a 3D printer early adopter. Here's a basic FAQ I've developed based on my own experiences and extensive research into classroom 3D printing."

"3D printing has been around for a long time, but only recently has it become available to the general public. My friends and family still think of a 3D printer as some sort of miracle device that can make whatever you want at the push of a button. Of course, we as creators know that it takes a lot of work to go from an initial idea to a final 3D printed product. There was a period of time where everyone was telling me I HAD to make prosthetic hands because I own this futuristic 3D printer and I had a social responsibility to use it for the forces of good.  I think of 3d printers like any other tool such as a table saw or lathe. Sure you can make just about anything, but what do you want to make? I've always loved the aesthetic of boy's action toys so I couldn't resist the opportunity to make my own action figures."

"I am by no means a 3D printing expert.  But I do have three 3D printers in my library makerspace (and one in my previous space).  And I have a lot of students who are very interested in learning more about 3D printing.  Some students have built their own 3D printers from kits and love to come hang out and tell me about their latest projects.  Other students have no CAD (computer aided design) experience but are eager to start building. In order to help all of these students better utilize and access our 3D printers, I created a short, Intro to 3D printing session that I teach afterschool every quarter.  It's essentially an orientation to how 3D printing works, how to create a design and how to get it ready to print."

"Do-it-yourself maker community Instructables is teaming up with global 3D printing network 3D Hubs for a new contest that will see 15 lucky winners walking away with a top of the line desktop 3D printer. The 3D Printing Contest 2016 is looking like it is going to be one of the biggest 3D printing design competitions of the year, and they have an impressive prize pool to prove it. Winners will be able to win one of an assortment of some of the most popular 3D printers on the market, not to mention 3D printing vouchers being awarded for every contest entry."

"With the explosion of 3D printing in schools around the world, the variety and impressiveness of things that students and teachers are printing with this powerful technology grows every day. Check out all these different objects that have been created with 3D printers. Some of these items are changing people's lives! Hopefully some of these ideas can inspire you to start exploring 3D printing, or to try something new if you're already using this wonderful technology."

How to Ensure that Making Leads to Learning http://t.co/jqjmk9NJlo #makered

"IN THE small town of Fayetteville in northern New York, you'll find the local library in an old furniture factory dating from the turn of the 20th century. The refurbished building retains hints of its industrial past: wooden floors, exposed beams, walls lined with carefully labelled tools. But instead of quietly perusing stacks of books, many of the patrons are crowded around a suite of 3D printers. One machine is midway through a pink mobile phone case; another is finishing up a toy sword. This is Fayetteville's maker lab - and it may very well be the future of libraries."

"Apple has built its legacy by taking new technologies and innovating on them for ease of use, as seen with the iPod, iTunes, iOS, and so forth. Now their latest patent describes a full-color 3D printer that could possibly do the same for additive manufacturing."

"A few days ago, I met Manuel Herrera at MORENet. He has an amazing maker space where students engage in creative thinking on a daily basis. It's a bastion of creativity and wonder and his passion for it is contagious. However, as we talked about prototyping and design thinking, he mentioned something surprising. "We have a 3D printer, but only a few students know how to use it for creative purposes. Most students download templates and print things out. There's not much actual creative thought that goes into it." "So, what's the answer?" I asked. "I think they need to start by making things by hand," he said."

"You've read about the maker movement. You've seen the posts with 3D printers, laser cutters, and three-axis mills in shiny new labs. And you want your students to start making, too. But you've got one big problem: you don't have a full lab -- or even a 3D printer -- because, like many educators, you don't have the biggest budget. Maybe you have no budget at all. But what if you could get started making tomorrow and didn't need all the fancy tools to join this movement? Making starts with a mindset, and simple materials are all that you need to get started. There are resources all around you, materials hidden in plain sight, tools just waiting to be used for a creative purpose. And with a little dose of ingenuity, you'll have your students making in no time. One perfect way start making on the cheap is through upcycling, the intentional transformation of hard-to-recycle materials into new products, thus saving them from the landfill. This type of real-world project not only teaches making skills but also helps you integrate making into your subject area. Study material science, explore industrial design, or dig into environmental education. As an added bonus, a project like this ignites your students' entrepreneurial spirit. Here's the five-step strategy that I've used to get my students making products out of hard-to-recycle materials. These steps could be done in one class period each, but if you want more time for ideas and iteration, feel free to expand the timeline as you go. Expect a beautiful mess, a bit of chaos, and a lot of fun as your students start to save the landfills -- by design."

"There have been dramatic headlines about 3D technology, encompassing ideas to use 3D printers to make clothes, food, firearms and the parts of a house. It's also making an impact on education, with plans to put 3D printers into schools in the United Kingdom and the United States. These technologies hold massive potential for young people both in and out of school."

"I have a couple of more 3D printing projects that I haven't written about this year, but by the time this posts it will be the last day of school, and I feel like this would be the right time to reflect on what a year of 3D printing in the classroom was like. I started the year with a lot of ideas and excitement, but I wasn't really sure how the year would pan out. Looking back now I couldn't be happier. The level of learning that occurred this year was more than I expected. As excited as I was at the prospect of using a 3D printer in the classroom, I was nervous that I wouldn't be able to figure out how to tie it to the curriculum. I wondered if my students would be able to understand how it works and be able to use it effectively. I was concerned that I wouldn't have time for projects with all the other demands that happen in a classroom. My concerns were overshadowed by the novelty and the excitement of the printer. I think that is what many of my students felt too. They were curious, excited, and bewildered."

FROM MY CLASSROOM: 17 Tips for using a 3D printer http://t.co/7NkmySscF2 #iste2015

"When 3D printing was first introduced over 30 years ago it felt like something more likely to appear in a Star Trek episode than reality. Today, more companies than ever are utilizing this technology to take their concepts from the boardroom to the design table in a matter of hours. The first step of every "solid imaging" project - as the name was originally dubbed by inventor Chuck Hull - is using 3D printing software, or computer aided design (CAD) software, to create your digital blueprint and send it off to the 3D printer to have it created layer by layer. The first thing Chuck ever printed was a tiny cup for washing the eye, something boring yet innovative in that it would spawn objects that even good ol' Chuck probably never thought possible. Below is a list of many of these items that can be created by a 3D printer that you wouldn't think would be. These items were selected for this list because you'd probably not think of them as manufacturable items and because some of them cannot be produced with a single process while employing traditional manufacturing processes."

"3D printing really does sound more like a plot point in a science fiction film than an implementable educational tool, but it's swiftly becoming an accessible option to educators everywhere. In fact, MakerBot, a leading manufacturer of 3D printers, has recently announced the MakerBot academy, which is seeking individual investors to fund an initiative to get 3D printers into every public school in the United States. Other 3D printing start-ups have followed in other parts of the world as well."
