Our 3D Printer

Through funds raised at our 2015 Turkey Shoot Night of Raffles Fundraiser, we purchased a Kossel Model A 3D Printer from TKI, Turn Key Innovations, Merrimack.  Our printer was dedicated January 30, 2016.

 

Printing Policy

The Library’s 3D printer, including our 3Doodler Pens, are available to make three-dimensional objects in plastic using a design that the patron has provided as a digital computer file. 

  1. The Library’s 3D printers may be used for lawful purposes only.  The public will not be permitted to use the Library’s 3D printers to create material that is:
    1. Prohibited by local, state, or federal law.
    2. Unsafe, harmful, dangerous or poses an immediate threat to the well-being of others (Such use may violate the terms of use of the manufacturer)
    3. Obscene or otherwise inappropriate for the Library environment
    4. In violation of another’s intellectual property rights.  For example, the printers will not be used to reproduce a material that is subject to copyright, patent or trademark protection.
  2. Priority is given to Merrimack Public Library cardholders.
  3. The Library reserves the right to refuse any 3D printing request.
  4. At this time, there is no charge for this service.
  5. Print-on-demand objects must require less than 10 hours to print each piece.  Multi-piece requests will be considered on a case-by-case basis.
  6. The Library is not responsible for any damage, loss, or security data arising from the use of its computers or network, nor for the functionality or quality of content produced on the 3D printer.
  7. Supervision of the use of the 3D printer by Library staff does not constitute knowledge, or acknowledgment, of any unapparent final use of the 3D product, and the Library specifically disclaims any knowledge thereof.
  8. Only designated Library staff and volunteers will have hands-on access to the 3D printer.
  9. The Library reserves the right review all files before printing and to refuse scanning and/or producing any content at any time at the discretion of the Library Staff.
  10. Schedule and access to the 3D printer will be determined by Library Staff.
  11. This policy, adopted in January of 2016, will be reviewed every six months to allow for evaluation of the use of this technology by staff.

Approved by the MPL Board of Trustees January 19, 2016; reviewed and approved July 19, 2016.

Design Resources

These websites from 3dprinter.net are the major repositories for finding and downloading free 3D models for use with a 3D printer. The sites files range from very simple free 3D models to very complex 3D models.

3D Content Central

3D ContentCentral hosts free 2D and 3D CAD files from engineers and firms. You can also request models.

3D Parts Database

The Shapeways 3D parts database is a place where you can download free 3D models free for 3D printing. The files currently in the database have all been tested and printed by Shapeways and all “print for sure.” 

CG Trader

CG Trader has both chargeable and free models, both those ready for 3D printing and those not. You’ll have to use the filters to select just the free models.

DEFCAD

Operated by Defense Distributed, the site was a makeshift response to Makerbot Industries’ decision to censor firearm-related files uploaded at Thingiverse. They are started as a host of firearms related files, but have now expanded to the inclusion of ANY file, regardless of intellectual property rights. NOTE: DEFCAD files have been removed from public access at the request of the US Department of Defense Trade Controls. Until further notice, the United States government claims control of the information.

GrabCAD

GrabCad is a site for engineers to show off and share their CAD works, with over 75,000 free models available. .stl filter available.

TurboSquid

TurboSquid is a large repository of both pay-for and free 3D models. There’s no area dedicated specifically to 3D printing, but there are selectable filters such as .stl and .sldprt (Solidworks part).

Thingiverse

Thingiverse is a huge community of people who create and share 3D designs freely, so that all can benefit from them. Widely used by the RepRap Project, and by 3D Printer and MakerBot operators.

Tinkercad

A free, easy-to-use design tool.


Trace Parts Online

TraceParts is a huge 3D parts database founded in 1989 with some very complex CAD files available in numerous formats, including .stl.

Trimble 3D Warehouse

The Trimble 3D Warehouse (formerly Google 3D Warehouse until purchased by Trimble) is a free, online repository where you can find, share, store, and collaborate on free 3D models created in SketchUp. This is a great place to look for models of famous buildings, as SketchUp interacts with Google Earth.
