Home Menu3D Design and Printing
3D printing is a process whereby a 3D design is turned into a real object.
First, software is used to slice the 3D design into layers before each layer is reconstructed on a 3D printer. 3D printing is great for prototyping and making unique one off items
3D Printing Policies
- 3D printer are only handled by Staff and prints are only available in PLA.
- The cost of printing is $0.10 per gram.
- Patrons may only submit a total of 1 file at a time; patrons cannot submit a new print until they have picked up their previous print.
- Prints must be picked up within 3 weeks or they will be discarded.
- Staff may refuse to print designs that are harmful or dangerous, based on their discretion.
How do I use the 3D Printing Request service?
- Create or download your design.
- Submit a 3D Printing Request form, you can email your file or bring a drive to the Library.
- Once the print is complete, Library staff will contact you with information on how to pay for and collect your print.
Filament colors: Red (transparent), Orange, Yellow, Green, Blue, White, Black, Natural (transparent)
Tips and Tricks
- Save your design as an .STL file
- Make sure your design is the right size or scale. Adventurer 3 has a 150*150*150mm print volume limit.
- The infill density defines the amount of plastic used on the inside of the print. A higher infill density means that there is more plastic on the inside of you print, leading to a stronger object. An infill density of around 15% is used for models with a visual purpose.
