Not only FDM: Other Types of 3D Printing

Submitted by Jason Griffey on November 20, 2014 - 10:36am

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 Plastics of 3D Printing

Submitted by Jason Griffey on November 13, 2014 - 9:41am

Editor's Note: This is the third of a series of posts excerpted from Jason Griffey's Library Technology Report "3D Printers for Libraries."

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 »

Types of 3D Printing: Fused Deposition Modeling

Submitted by Jason Griffey on November 5, 2014 - 12:44pm

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 »

How 3D Printing Works

Submitted by Jason Griffey on October 29, 2014 - 8:04am

Editor's Note: This is the first of a series of posts excerpted from Jason Griffey's Library Technology Report "3D Printers for Libraries."

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.   Read More »

Metadata, Schema.Org, and Getting Your Digital Collection Noticed

Submitted by Patrick Hogan on July 11, 2014 - 10:12am

Editors Note: This post is an excerpt from Improving the Visibility and Use of Digital Repositories Through SEO, by Kenning Arlitsch and Patrick S. OBrien. The authors, along with Montana State colleagues Jason Clark and Scott Young, will be teaching the online course/workshop Search Engine Optimization (SEO) for Libraries, which starts July 17.

Metadata schemas are powerful frameworks for organizing content, and libraries have long used them to describe their holdings (think MARC). Numerous schemas exist for academic disciplines: CDWA is used for art, Darwin Core for biology, EML for ecology, DDI for social sciences, and so on. Read More »

Innovative Interfaces Acquires VTLS

Submitted by Marshall Breeding on June 2, 2014 - 10:47am

Innovative Interfaces has acquired Blacksburg, VA-based VTLS as part of its strategic expansion strategy. This move follows the acquisition of Polaris announced in April 2014. The acquisitions were conducted in parallel, with different schedules for closing. The acquisition of VTLS significantly expands Innovative’s international reach and brings a number of new technology products under its corporate umbrella. VTLS had been the longest standing company remaining under the ownership and management of its founder in the library technology industry. VTLS and its precursors have been active since 1974, initially through Virginia Polytechnic Institute and State University--better known as Virginia Tech--and since 1985 as an independent company.

Innovative Interfaces Acquires Polaris Library Systems

Submitted by Marshall Breeding on April 1, 2014 - 9:35am

In a move that further consolidates the library automation industry, Innovative Interfaces, Inc.  has purchased Polaris Library Systems.   Innovative, one of the largest companies in the industry, with a presence in many international regions, and with customers from all types of libraries significantly strengthens its presence in the US public library arena by acquiring the company that has performed well in this sector, winning the majority of municipal library procurements in recent years.  The acquisition marks further expansion of Innovative since it was sold by co-founder Jerry Kline to private equity investors.  Previous expansion included opening international offices in Dublin, Ireland and Noida, India.  Read More »

Where To Turn for Background, Context, Ideas, and Inspiration on User-Centered Design
