3D Printing @ HML – What will YOU print?

What is 3D printing and what is it used for? HML 3D Printing Statement


3D printing is the making of parts and products using a computer-driven, additive process, one layer at a time. 3D printing builds parts out of plastic, metal and other materials directly from CAD drawings that have been cross sectioned into thousands of layers. Uses of 3D printing include prototypes, molds, final products, household items, hard to find parts and personalized items. It provides a faster and less costly alternative to machining.

Procedures & Requirements -All users must read and agree to our 3D printing policy.

Print files should be emailed to huntingtonmemoriallibrary@gmail.com, brought into the Library on a USB drive or SD card (microSD Card) or be provided via a link to the object along with the exact specifications. The cost for printing is $0.10 per gram of filament used.

How to request a 3D print of your model at HML.*

Using the 3D printer is easy. All you need is a 3D model saved or exported in .STL (stereo lithography) or OBJ (object format) file format. .STL files can be exported from most 3D design software packages. Additionally, you can find models in .STL format on websites like Thingiverse.com. The printers are available for child and adult users alike.

Request a print via E-mail:
If you submit your 3D order online, we will print it for you to pick up. You can email the file with the information below or a link to the file with exact specifications to huntingtonmemoriallibrary@gmail.com

If you do not know or if you leave a specification item blank, the 3D printing staff will choose for you. We may need to make changes to your specifications and will notify if we do so.

Print via Computer or microSD Card
Bring your file to the Library on a USB drive or SD card (microSD Card) and we will print it or help you print it yourself.

Individual use of the 3D printers
After becoming “certified” in using our machines, you may print an object yourself during one of our 3D printing open hours or by appointment.  You should be there for the start and finish of your print job. It may be necessary to be there most of the time.

Open Hours
Once a month there will be a trained staff member and/or volunteer available at open hours for 3D printing.

Reserve a 3D printer, scanner or laptop
An appointment to use our 3D printers, scanners or 3D modeling laptop may be made by emailing huntingtonmemoriallibrary@gmail.com or by calling the library at 607.432.1980.

* Printing will be done on a first come/first serve basis. In all cases we will review your file and a staff member will decide if/when to print. Your print request will be queued as deemed appropriate by staff. It takes hours to print a single object and it may take a couple of weeks for the library to complete your 3D print request. The library aims to complete any submitted model within 7-10 days; however, models that require the printing of many components or high patron demand may lengthen the overall process.

Do I need to be present the whole time my object is printing?

If you are a Certified User and want to print the job yourself, you must be present at the start and finish of the print job. Most jobs are quick, but for longer jobs, we understand you may need to go and come back. We do recommend you either stay for the length of your print, or check in with your print periodically. Errors in printing are common, and if they occur while you are not present to fix them, you may need to reschedule your print job for another day.

What is the cost of printing?

The cost for printing is $0.10 per gram of filament used. We can give you an estimate prior to printing your model, and will let you know the exact price once it has finished. Most medium sized or medium complexity models cost $5.00 or less. Remember, the more intricate or larger your model is, the more filament it will use.

Can I choose the color I want?

Yes, you may choose from the colors that we have in stock. The colors available may change without notice, and we cannot guarantee that your selected color will be available. In the event that your chosen color is out of stock, we will contact you to choose another color.

How do I reserve a computer for 3D modeling?

Email us at huntingtonmemoriallibrary@gmail.com for computer availability.

What 3D printers does HML own?

HML has a Lulzbot Taz6

Where can I find 3D designs to print?

Thingiverse hosts many different types of models, some of which may not be acceptable for 3D printing. . If you’re submitting a file from Thingiverse, check to see that the model has been made on a desktop 3D printer. For the best chances of getting a successful print, choose a model that other people have successfully printed

How do I design my own Project?

For your first print, we highly recommend that you start small. 3D printers use metric coordinates. For consistency, it is recommended that you design in millimeters and export your STL in millimeters. There are many free resources out there for designing your own model. Here are a few:

Tinkercad (free)
Sketchup (free)
Autodesk Fusion 360 (available for use in-house)

What if I don’t have an .stl or.obj file?

Most 3D modelling software should have the option to export as an .stl or .obj file.  Please contact us if you need help.

What are the dimensions of the largest thing I can print?

Approximately 11.02 in x 11.02 in x 9.8 in.  If you need larger, you may print in parts and attach them later.

What are typical costs?
The charge to print is $.10/gram, and several small pieces can be batched together.  Most prints are less than $5.00.

When will my job be finished?
In addition to the time required to print, it depends on how many other jobs are waiting to print.  We will give you an estimate when you submit your job.

My model didn’t print well, what do I do?
There are a lot of factors to a successful print. Here are a few troubleshooting resources.

3D Scanning:

3D Scanning is available at HML. Some objects may not scan well, including those with shiny, reflective, or fuzzy surfaces. In addition, objects that are dark in color may not scan well. Flat objects may also be difficult to scan.

3D Printing Statement:

A library’s role in the community is to provide leadership in learning.  In this new digital age, that role becomes increasingly important as access to new technologies will help people of all ages build the skills and knowledge they will need to succeed.  Huntington Memorial Library’s mission is to strengthen the community by providing an environment that supports life-long learning. One of the ways that we will accomplish this is by providing access to state of the art technology such as 3D printing.  According to the American Library Association, “3D printing expands the frontier of the ongoing digital transformation of our society, and library professionals are helping people and communities take advantage of this development. Library 3D printing is empowering people to engage in creative learning, launch business ventures and solve complex health problems.” 3D printing is especially important technology to provide for adults to help support their ability to continue to compete in an increasingly technological world.

Implementation and Use at HML

HML has a LulzBot Taz 6 (rated as the best overall in the January 2016 issue of Make Magazine) and a Printrbot Play (rated as the best for Schools.) Both printers will be available to use with the Printrbot Play also being used for community outreach, senior centers and pop-up library events.  All users must undergo training on each printer before using them to print.  We will provide a laptop with software and links to popular sites for 3D Printing and design on library computers.  We will use the 3D printers to enhance existing programs and to build new programs around them. Programs will include basic introductions to tools that are available for free, scanning of objects with 3D scanners, one-on-one tutorials and show-and-tell style events.   We will also reach out to the community to provide opportunities that align with existing national printing efforts such as printing books for blind children and prosthetic hands for disabled children.  We will also outreach to students and teachers to help mentor our open hour’s sessions, working toward the goal of having at least one expert-led open hours a week.

We expect the use of the 3D printers to be very high.  We have learned from conversations with other libraries and from online research that the 3D printer is the most frequently used item in their makerspace and in fact achieves such a high level of demand that the execution of the print jobs themselves must oftentimes be scheduled and performed by library staff. Sometimes, print requests can take up to two weeks to fulfill.

The first goal of the project is to foster creativity, invention, and innovation through 3D design. There will be open hours to allow free-play time to develop projects. The library staff have already consulted with the Tech Steering Committee and other local experts to provide the best experience possible. There will be one laptop and a desktop loaded with the design software for public use and training workshops will be scheduled. On August 1 at 6:30, a 3D Open Interest meeting will be held at HML.

The second goal of the project is to use 3D printing to increase collaboration and partnership opportunities in the community. HML plans to reach out to area organizations to find needs and opportunities for 3D printing. Enablingthefuture.org is a national organization that build prosthetics for children in need and the library plans to participate. Pop-Up 3D printing is planned for Senior Tech Outreach. It is our hope to host a Maker Fair with other youth organizations to display projects.

The third goal is to improve access to library technology resources for local business owners’. Local entrepreneurs will be able to use state-of-the-art equipment to benefit their business goals. The library will invite local experts to illustrate real life applications of 3D printing and prototyping for local businesses.
