Editor's Note: This is the fourth of a series of posts excerpted from Jason Griffey's Library Technology Report "3D Printers for Libraries."
As noted in earlier posts in the series, FDM (fused depostion modeling) printing is by far the most common inexpensive method of 3D printing. In this post, we’ll look at alternatives.
We are starting to see stereolithography (SLA) printing move downmarket into the affordable-for-libraries zone. I’m aware of a couple of libraries that have already purchased stereolithography printers. Read More »

The substrate for FDM printers are almost exclusively some form of thermoplastic that is delivered in an extruded wire-like form on a spool. It is usually called “filament” in the generic. The two common diameters for use in FDM printing are 1.75mm and 3mm, and a specific diameter is called for by the print head being used for the printer in question. A printer that uses 1.75mm diameter filament won’t be able to use 3mm without retrofitting the hardware for the difference, and vice versa. Slightly more common, the 1.75mm diameter is used by Makerbot Industries, the most popular manufacturer of FDM printers. Read More »

Editor's Note: This is the second of a series of posts excerpted from Jason Griffey's Library Technology Report "3D Printers for Libraries."
Fused deposition modeling defines 3D printing for most people, as it’s by far the most common and in many ways the simplest technology for 3D printing. Fused deposition modeling uses a variety of plastics that fall within a range of melting points and that fuse when melted and resolidified, the most common of which are ABS (acrylonitrile butadiene styrene) and PLA (polylactic acid). We’ll discuss the specifics of these and other print substrates below. Read More »

The simplest way to understand a 3D printer works is to imagine it as a machine that makes bigger things out of smaller blocks. In some cases the “blocks” are a powder, in some they are melted plastic, or they may be a ultraviolet light sensitive resin, but always the process is large things being made from smaller substrates. A 3D printer is a simple sort of robot that understands how to manipulate the raw material it’s working with in three dimensions rather than just two, as an inkjet or laser printer does. This type of manufacturing is also called additive manufacturing, as opposed to more traditional subtractive manufacturing, where material is removed from a larger sample to create custom shapes in a process like milling, lathing, or CNC (computing numerical control) machines.

I've seen some interesting alternative inputs technologies that will be coming to computer users this year. I'll share video demos of two that I’m most excited about are: the Leap Motion and the Myo armband.
The Leap Motion is a small camera-based sensor that connects to your computer and “watches” an area above your desk for hand movement, translating that movement into control of your computer. You can, for example, wave your hand to scroll a page, turn your fingers to control volume, and pinch and zoom images by literally pinching the air. Most of the gestures seem to be translated from current touchscreen technology, but I’m very excited about the opportunity to develop a new language of interface with a product like this. The Leap Motion should be available for purchase this May, for $79.
Here’s a quick video to demonstrate how it looks and works. Read More »

We thought that September was a big month for technology announcements, well... then October happened. I would bet that there hasn’t been a busier month for new tech hitting the streets in a long, long time. Here’s the rough summary of what came out this month.
Apple announced a 7.9-inch version of the iPad, dubbed the iPad mini. A smaller screen brings a smaller price: the lowest priced version of the mini coming in at only $329...but even with the smaller screen, it has the same resolution as the iPad 1 and 2, which means that it will run all 275,000 iPad apps without any modification.

September has become the keystone month in the US for technology announcements. This eventful month featured two major and one minor (but interesting!) announcement: Apple and the iPhone5, Amazon with their new set of Kindles, and Makerbot Industries with the announcement of the Replicator 2.

I have a not-entirely-undeserved reputation as a fan of Apple’s hardware and software. And it’s true that I think that Apple is charting the future of computing with the iPhone and iPad, and that no one has built a tablet that I could possibly recommend that ran anything except iOS.
Yes, you can collect whatever wagers there were on the table as to when I’d like an Android device. Because I really, really like the Nexus 7, the 7 inch, Google-backed-and-Asus-built Android 4.1 tablet. It’s fast, it’s pretty, and Android 4.1 puts it far ahead of other Android tablets for the time being. Did I mention that it’s also $199?

Once a year, Apple holds its World Wide Developers Conference in San Francisco, the highlight of which for non-developers is the Monday keynote. In prior years, the keynote was the Steve Jobs show, where Steve got to be his most Steve-ish, taking digs at competitors and talking about how awesome things are and will be for Apple over the coming year. This year there is no Jobs, but there was an absolutely deluge of news from the keynote, hosted by CEO Tim Cook and starring the main players in Apple’s current corporate structure.
Practically every news outlet in the world will have a summary of the news coming out of WWDC, so I’m going to focus on the things that I think are important to libraries. Apple had three main announcements: updates to their laptop line, which is their most popular type of computer sold; and what to expect in the two new operating systems launching this year, OS X Mountain Lion and iOS 6.

Editor's note: This post is adapted from the introduction to Jason Griffey’s new Library Technology Report “Gadgets and Gizmos: Libraries and the Post-PC Era.” Jason revisits the technologies that he highlighted in his 2010 report. And he beats himself up a bit over it. Help him let go of the past; excuse him from predicting the future; and join him in discussing the gadgets your patrons are using today: Jason will be presenting a two-part workshop on May 10 and May 24.
Way back in April 2010, Library Technology Reports published “Gadgets and Gizmos: Personal Electronics and the Library,” but it was January of the same year when I turned in the manuscript for editing and effectively locked down the content. Nearly every single thing about it is now irrelevant at best, and downright ridiculous at worst. Read More »
