When 3D printing goes wrong

By Dawn Wilson

3D printers are the next major technology item for many libraries. McGoogan currently has two printers, both from MakerBot: a 5th Generation single color printer and the double-extruder 2X model for printing two colors at once.

Requests are open to the UNMC and Nebraska Medicine, and we currently print objects for academic, clinical, and research use. As we’re still in the novelty and testing phase, we just never know how well the files are going to print! Just like a paper printer, some copies come out great and others are… not quite right. A lot depends on the file and type of printer it was designed for, but even more can be trial and error.

So how does it work (ideally)? Primarily, the files we use come from Thingiverse and Embodi, from Creative Commons files that other users have graciously uploaded. The printers use plastic filament (either PLA or ABS), which is colored and thicker than fishing line. The machine melts the filament and follows the pattern from the downloaded file, squirting a thin line of melted filament into a base and then the shape. When it comes to protrusions, the printer adds supports (to be removed later) to hold up sections that do not touch the build plate (such as the curved portion of a mandible). Inside, the honeycomb infill gives strength to the finished model.

So that’s how it’s supposed to work! But here are a few things we’ve learned along the way:

• PLA filament comes in a multitude of colors.
• ABS filament gives you a smoother build.
• Sorry, we cannot turn a photograph of your cat into a 3D print.
• 3D printers can jam, just like paper printers! If you catch it right away, you might be able to clear the jam and resume, otherwise you’ll end up with half a print. But the cool thing is that then you can see the inner workings of the build!
• It’s best to build on a raft so your print doesn’t fall over halfway through.
• Heated build plates bring their own list of problems when the models don’t want to stick.
• Large prints can take days. Our longest print took over three days.

Going into our third month, we’ve accepted 130 print jobs, most of which have been successful. Take a look at the photos to get an idea of the process!

Get better RefWorks records from Google Scholar

By Cindy Schmidt

If you’ve ever imported a Google Scholar “hit”/record into RefWorks, you know that the results can be disappointing.  If you’re lucky, the authors names, article and journal titles, and page numbers will be formatted correctly.  The abstract, DOI, PMID and other useful (sometimes essential) information are rarely included.

If you’re willing to do just a little extra work (2 more clicks and a bit of scrolling), you can usually obtain a beautiful PubMed-quality, RefWorks record from Google Scholar.  Here’s how it’s done:

1.  To do any type of export from Google Scholar to Refworks, you must first visit the Google Scholar “Settings” page (cogwheel on Scholar homepage).

2.  Scroll down to the “Bibliography manager” section near the bottom of the page.  Change the default “BibTeX” selection to “RefWorks” and click “Save.”

step2

3.  Now we come to the extra steps that you’ll need to take if you want a beautiful RefWorks record.  Instead of clicking on the “Import into RefWorks” link under the “hit” of interest, click on the “All __ versions” link.  This is your first extra click.

step3

4.  Now look for a record from ncbi.nlm.nih.gov (#1 in figure below). When you find a “hit”/version obtained from ncbi.nlm.nih.gov, look to the right. Is there a “Full Version” link or “nih.gov” link on the right? If so, the record you’ve located is a PMC record not a PubMed record. Keep looking for another ncbi.hlm.nih.gov “hit”. The PubMed record from ncbi.nlm.nih.gov will often be among the last versions listed in Google Scholar.

step4

5.  When you find the needed version, click on its “Import into RefWorks” link (arrow 2 in the figure above).

6.  If you’re not already logged into your RefWorks account, you will be asked to login.

7.  The beautiful record will appear in your RefWorks account.

8.  When you return to you Google Scholar results, you will have to use your browser’s “back” button to leave the “versions” list and return to your search results page.  This is the second extra click.

From the archives: Historical Nebraska pharmacy resources

Omaha Druggist, April 1900
Omaha Druggist, April 1900

By John Schleicher

The archives hold historic resources in all areas of the health professions, including pharmacy. These include various periodical materials such as pharmacists’ scientific and trade publications, from national, regional, state and local publishers and organizations.

The Omaha Druggist: a Monthly Journal of Pharmacy (see image), was published in the city from 1888-1927. The Nebraska collection holds issues from 1900-1927. This journal contains advertisements for various sideline products, such as candy, cigars, hair tonic and snuff, which might be featured in the traditional drug store setting. The publication also has news of the profession across Nebraska and the upper Midwest region, including drug stores for sale, and a section of news about individual pharmacists called “Personal Mention.”

Other titles in the library’s collection include: Nebraska Mortar & Pestle (from the Nebraska Pharmacists’ Association, still in publication, issues from 1938-2015) and the Midwestern Druggist (issues from 1925-1972), among others.

To visit the archives and the Nebraska collection, contact the Special Collections Department at 402-559-7094 to schedule an appointment or inquire at the AskUs desk on the 6th floor of Wittson Hall.

From the Archives: Did grandpa go to school here?

Three generations of Karrer family medical graduates in the Library of Medicine, 1979.

By John Schleicher

Or great-grandma? Or Uncle Charlie or Cousin Kate? A number of Nebraska families have several generations of graduates and/or faculty members of the various health sciences colleges at UNMC. Karrer, Gentry, Wigton, Cloyd — just to name a few of those families.

The archives has various research resources available if you are interested in finding out more about a relative or ancestor who graduated from UNMC, was a faculty member here, or a health professional in Nebraska, from the late 19th through the 20th century.
