"Today, MakerBot has unveiled their guide aimed at teachers and students alike, titled, 'MakerBot in the Classroom: An Introduction to 3D Printing and Design', with hopes of bringing 3D printing into more classrooms around the world. The guide is broken down into three chapters which focus on all the important and vital aspects of 3D printing."

"Robots! We just love them: 3D printing and robots are a match made in mechanical heaven. So, we've made a short list on the best 3D printed robot projects you can find out there. This list is divided into two parts."

"Modio is a new and free iPad app that anyone can use to design model robots for 3D printing. The app features a large collection of robot parts that you snap together to design your 3D robot model. You can mix and match parts to heart's content. Modio provides a visualization screen that will reveal the dimensions of your model before you print it. Included with those dimensions is an estimate of the time it will take to print the model."

"Researchers at the Massachusetts Institute of Technology unveiled a new 3D printing method on Friday that employs transparent glass as precursor instead of plastic. The method, called 3DGP, works basically the same way that conventional 3D printing does though the team found that they could modulate the light transmission, reflection and refraction qualities by precisely varying the thickness of the print."

"In our three gr. 8 classrooms, students have learned the process of 3D printing using dual extrusion (printing with 2 colours) using a Makerbot Replicator 2X. Last year, due to the large number of students we had using the printer, we needed another to keep up, but this time we chose an AirWolf 3D HDR printer for a few reasons: cloud based slicing via Astroprint, larger print size, and the ability to print with a wider range of materials. Added bonus - the tech support help from AirWolf3D is excellent. While I've posted some examples of how our students design and print using dual extrusion with the Makerbot, my teaching partner, Marc Westra, and I quickly learned the process was quite different using an AW3D HDR - like taking the elevator instead of the stairs. Here's what I learned over the Christmas break, and what we'll be teaching our students…"

"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."

"So here's the question(s): - do have a lesson plan you would be willing to share on 3D printing? - do you have a link to a great blog post about 3D printing in classrooms? - what topics that you think should be covered when talking to teachers about 3D printing?"

"Most people who are familiar with 3d printing have been to Thingiverse.com or at least have heard of it.  With over 1 million uploads to the site, its the place to go if you need a 3d printable model of most anything.  But where else could you check to download 3d models if you wanted a variety? I've put together a list of all the 3d model libraries out there in order to help give you more options as makers.  If I missed one or if a new website pops up after this post goes live please let me know and I'll get it added to this list.  I can't wait to see what you print.  Send me a tweet @Makerspaces_com "

"When I think of 3D printers, I am instantly taken back to the days of watching George Jetson: Imagine pressing a button and opening a magic door to exactly what you had asked for. While 3D printing technology seems frighteningly close to that futuristic memory, the truth is, there is HUGE potential for 3D printing to impact math education in a variety of ways."

"Washington, D.C. -The American Library Association's (ALA) Office for Information Technology Policy (OITP) today released "Progress in the Making: Librarians' Practical 3D Printing Questions Answered" (pdf). Co-authored by 3DPrint360 CEO Zach Lichaa and ALA Senior Policy Analyst Charlie Wapner, the document poses and answers sixteen practical questions related to establishing 3D printing as a library service. All of the questions were fielded from library professionals interested in 3D printing technology."

"Our CREATE Education Project champions partner organisations who share our ethos for making 3d printing as easy, accessible and affordable as possible for everyone. In the name of open source we find synergies with many pioneers who understand that sharing is the way forward to developing and seeding innovation for new technologies. When we find these pioneers it is our mission to provide access to our community so that everyone can enjoy the progress and even add to it themselves.  One of the more challenging aspects of introducing 3D printing into schools is the complexity of 3D modelling software and the general cost of having computers that can handle such software. A good majority of schools have adopted a cheaper method of computing which is the tablet. iPads are fast becoming common in the classroom and this is where Gravity Sketch comes in."

"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."

"3D-printing technology still appears too unreliable, too complicated, and too slow for mainstream adoption. The companies making investments in it are the ones with significant amounts of capital to purchase $100,000-plus equipment and train the personnel needed to operate 3D printers. But despite these obstacles, 2016 looks promising for the 3D-printing industry. Here are five things to look forward to in the new year."

"8-year-old Kaori Misue was born without fingers. Usually, creating specialized prosthetics costs upwards of $15,000. However, thanks to a 21-year-old inventor, Misue received a prosthetic hand which has changed her life. Gino Tubaro is offering kids born without limbs the chance to receive a cheap 3D printed prosthetic. Misue's mother, Karina Misue, adds: "It was magical… The confidence it gives kids is tremendous. They're using it with pride." Tubaro's 3D printed prosthetic designs are part of the "Alternative Limbs Project", which began in his home of Argentina. The prints come in a range of designs, offering users the chance to decide what they need the prosthetic for most, whether it's playing an instrument or ping-pong. The prosthetics for kids can even be superhero themed (and shoot rubber bands)."

"Everyone agrees that it's important for children to learn new technologies such as 3D printing, robotics, and virtual reality. The challenge lies in finding the best way to teach those skills to young students. Plenty of organizations have taken on that challenge and have come up with creative ways to teach kids about technology while allowing them to have fun as they learn. One of those companies is 3DBear, a Finnish startup founded three years ago by Jussi Kajala and Kristo Lehtonen. 3DBear is an app that allows children to 3D design their own toys in augmented reality. Available for both iOS and Android, the app is simple enough for kids to use, allowing them to superimpose their own designs on their surroundings using their phone's camera. Kajala and Lehtonen wanted to capitalize on the popularity of such games as Pokémon Go and use the appeal of augmented reality to educate, not just entertain."

"As of today, there are 95(!) 3D pens on the market. Read our comprehensive guide to find the best 3D pen for kids, hobbyists, and artists. 3D pens are fun, whether you're a kid, a hobbyist or an artist - they can enhance your creativity and help you get a better understanding of three-dimensional objects."

"A 3D printer company with a strong education background can be invaluable to school leaders hoping to help students turn abstract concepts into working models, says Johan Broer, a MakerBot spokesman. Each printer company has its own school-focused offerings. A hands-on learning guide and bundled kits along with a curriculum could integrate engineering concepts with core academic knowledge in science, math, art and 3D printing technology.

"Print a 3D logo on your t-shirt! You can 3D print directly onto a t-shirt with your home printer using standard PLA, ABS or other regular filament."

"Integration into the Kindergarten curriculum was a rather loose connection, but definitely a great introduction to 3D printing. One of the Kindergarten writing units revolves around "Looking Closely" at different things and writing about them like a scientist. Many of the Kindergarten teachers like to choose leaves as one of the objects students write about, so I decided to expand this idea into the design of a 3D printed leaf. To support students looking closely at small details as well as develop fine motor skills, each class worked together to make a blown up drawing of a leaf. In order to avoid having the whole class fighting over space to observe and draw around one piece of butcher paper, I set up the class so that I had three stations for the students to rotate around. The other two stations were a Bee Bot coding station and an Engineering Design challenge with Legos (design a bridge strong enough to hold a water bottle)."
