Über dieses Buch

Learn how to manage and integrate the technology of 3D printers in the classroom, library, and lab. With this book, the authors give practical, lessons-learned advice about the nuts and bolts of what happens when you mix 3D printers, teachers, students, and the general public in environments ranging from K-12 and university classrooms to libraries, museums, and after-school community programs.
Take your existing programs to the next level with Mastering 3D Printing in the Classroom, Library, and Lab. Organized in a way that is readable and easy to understand, this book is your guide to the many technology options available now in both software and hardware, as well as a compendium of practical use cases and a discussion of how to create experiences that will align with curriculum standards.
You'll examine the whole range of working with a 3D printer, from purchase decision to curriculum design. Finally this book points you forward to the digital-fabrication future current students will face, discussing how key skills can be taught as cost-effectively as possible.
What You’ll LearnDiscover what is really involved with using a 3D printer in a classroom, library, lab, or public space
Review use cases of 3D printers designed to enhance student learning and to make practical parts, from elementary school through university research lab
Look at career-planning directions in the emerging digital fabrication arena
Work with updated tools, hardware, and software for 3D printingWho This Book Is For

Educators of all levels, both formal (classroom) and informal (after-school programs, libraries, museums).

3D Printing: State of the Art

Frontmatter
Chapter 1. Why Use a 3D Printer?
Abstract
In the last five years, 3D printing has gone from a technology hyped as capable of solving any problem to one of disillusionment as people realized it took more expertise than some advertisements implied. Now machines are getting both easier to use and more powerful, and there is a creative explosion in both printer technology and applications. But we are still not quite at the point of clicking Print without any thought on the user’s part.

Chapter 2. 3D Printers and Printable Materials
Abstract
In the last 10 years or so, 3D printers have gone from being large pieces of industrial equipment, to hobbyist novelties, to classroom staples. This chapter reviews the range of technologies that all fall into the broad category of 3D printing. There are many different 3D printers, but fundamentally they all create an object by building up one layer at a time on some sort of platform. As we discuss in Chapter 1, the basic idea of 3D printing (or additive manufacturing, if you prefer) is that you create objects by building them up one layer at a time.
Joan Horvath, Rich Cameron
Chapter 3. 3D Printer Workflow and Software
Abstract
People are often startled and intimidated when they discover that a 3D printer is not really the same as a paper printer. Although some consumer 3D printers have a “print” button, there are some steps needed to get to the point of pushing it, not to mention the need to monitor what happens afterwards. We prefer to think of 3D printing as more like cooking than printing. Just as you would not expect to cook by just pressing a “bake” button without setting some temperatures and timers first, 3D printing requires some knowledge of your printer, the materials you are using, and the design you are trying to print. If any of those have issues, getting good results is challenging.

Living with Your 3D Printer

Chapter 4. Selecting a Printer: Comparing Technologies
Abstract
There are now hundreds of different models of 3D printer on the market. But how do you even start to think about which one to buy? In this chapter, we will look at what 3D printer features are likely to be important for your intended uses, and also discuss how to estimate the long-term cost of ownership.
Joan Horvath, Rich Cameron
Chapter 5. Living with Your 3D Printer
Abstract
In Chapter 4, we talk about how to buy a 3D printer. In this chapter, we discuss what to anticipate when you bring it into its new home and unpack it. You do not need an expensive, special space for it, but knowing a few things about what a 3D printer really does not like might save you a lot of grief.
Joan Horvath, Rich Cameron
Chapter 6. 3D Models
Abstract
Your first step in using a 3D printer will be to create a 3D computer model. You do that by scanning an existing object, downloading a model from the web, or creating a model yourself. In each case, there are a lot of options to choose from. There is more to design than picking a software package, though, and there are design decisions you can make that can simplify the printing process.

3D Printing Curriculum Development

Chapter 7. Classroom Issues
Abstract
To this point, we have been focusing on the mechanics of choosing and using a 3D printer. However, the mechanics of using a printer to produce a good print is just a start. Deciding how to use the technology effectively is challenging, too. In this chapter, we discuss some issues common to most educational settings. In the remaining chapters of the book, we discuss particular opportunities and challenges for different disciplines and age groups.
Joan Horvath, Rich Cameron
Chapter 8. Art and Theater
Abstract
3D printing is a mixed blessing for artists. Like all media, it has situations where it is particularly powerful, and others where it is limited. The big minus for many artists is the need for a computer model to start with. Some like the texture of layer lines, while others consider them a nonstarter. In this chapter, we discuss some of the issues that arise when printing art objects and theatrical props in particular, from some challenging object shapes to ways to post-process a print for particular effects.
Joan Horvath, Rich Cameron
Chapter 9. Engineering, Math, and Science
Abstract
It might seem that technology-focused teachers would be early adopters of 3D printing. However, particularly in high school, teachers in these subjects often feel they have too much to cover to add anything new. We think this is unfortunate, and that 3D printing has real power to offer alternative ways of learning beyond writing down notes from a whiteboard.
Joan Horvath, Rich Cameron
Chapter 10. Language Arts and Social Studies
Abstract
People often ask us how to use 3D printers outside of obvious areas like robotics and art. Some of the most creative applications we have seen, actually, have been in disciplines that lend themselves to storytelling. We all made dioramas with cardboard in middle school, but we can now go beyond that.
Joan Horvath, Rich Cameron
Chapter 11. Elementary Students
Abstract
We are frequently asked what a makerspace in an elementary school should do and what equipment it can include. Elementary students have always made things, and just as the ability to make a typed report has migrated younger, so too can professional-looking art pieces. What makes sense will largely depend on the school style, budget, and similar factors that are not universal. In this chapter, we give you some anecdotal information and resources developed by early adopters.
Joan Horvath, Rich Cameron
Chapter 12. The Special-Needs Student
Abstract
Special-needs teachers always have to be creative and often must invent props to get their points across. 3D printing can have a particular role to play for learners who benefit from tactile interactions.

Building Lifelong Skills

Chapter 13. University Research Applications
Abstract
Many aspects of the 3D-printing ecosystem are still very much wide-open research areas. Novel applications and technologies to improve 3D printing will likely be coming thick and fast for a long time. There is a classic cycle of technology adoption called the Gartner Hype Cycle ( www.gartner.com/en/research/methodologies/gartner-hype-cycle ). In this cycle, when a technology such as low-cost 3D printing comes along, lots of people get excited. There is much over-promising and under-delivering as people rush into what they think might be a multibillion-dollar market. Early adopters buy one because it is cool, not necessarily because they have a use for it. In the case of consumer 3D printing, that peak probably came in 2012 or 2013.
Joan Horvath, Rich Cameron
Chapter 14. Community and Careers
Abstract
We are often asked what types of 3D printing–related jobs will be available in the future. Since it is pretty challenging to predict where the industry will go in the next couple of years, much less in a decade or two, any attempt to answer should be taken with a large grain of salt. Any 3D printer that a student uses now will have very little resemblance to an industrial printer used for metal parts. However, the skill of being able to envision something, create a computer model of it, and then transform that into a physical object will always be a valuable one.
