What is 3-D Printing?
3-D printing or additive manufacturing is a process of making three dimensional solid objects from a digital file. The creation of a 3-D printed object is achieved using additive processes. In an additive process an object is created by laying down successive layers of material until the entire object is created. Each of these layers can be seen as a thinly sliced horizontal cross-section of the eventual object.
Why offer this service?
The Library desires to offer community access to new and emerging technologies such as 3-D printers to inspire a new interest in design and help the community to bring their creations to life. The Library’s 3-D printers are available to the public to make three-dimensional objects in plastic using a design that is uploaded from a digital computer file.
- Set up fee: $2
- Cost of item: 25 cents per gram
- Deposit: 50% of the cost of item
- There will be no refunds.
Example: someone wants to print an item that weighs 25 grams. The cost of the item is would be $6.25. Their deposit would be $3.13 plus the $2 set up fee or $5.13. They would then pay the remaining balance of $3.12 when they pick up their item.
- The patron brings to the library a memory disk with the prepared file already in OBJ or STL format.
- The patron pays the $2.00 set up fee for the thorough ‘slicing’ process needed to prepare the file for printing.
- After the slicing, the patron is told the price for the printing job. The patron must pay the 50% deposit for the printing to begin.
- After the print is finished, the patron is notified. The patron then pays the remaining amount and claims the printed object.
- The patron has 7 days to pick up the item after notification or it becomes library property.

How to make your own files:
This virtual design is made in a CAD (Computer Aided Design) file using a 3-D modeling program (for the creation of a totally new object) or with the use of a 3-D scanner (to copy an existing object). A 3-D scanner makes a 3-D digital copy of an object. For examples of CAD modeling programs, see the list below:
Our 3-D printer only uses plastic, which comes in six colors. An object can only be 6 x 6 x 8 inches. A higher quality print can use more material, which will make the object sturdier, but also more expensive. The library reserves the right to refuse any 3-D print request.
