A process of creating physical three dimensional objects from digital files or models. Additive processing is used, in which successive layers of filament is laid down in thin layers until the entire model is complete.
Currently, Bierce Library has a MakerBot Replicator 5th Generation 3D Printer. The 3D printer uses 1.74 mm Polyactic Acid (PLA) fileament. PLA is a bioplastic made from renewable resources. Current colors available are listed to the left.
We also have a MakerBot Digitizer 3D desktop scanner and a Sense 3D Handheld Scanner. The Digitizer can turn every day objects into 3D models. Scans objects up to 8 x 8 in size on an accurate and easy-to-use platform; ideal for creating new objects or revising items. The Sense Handheld scanner can scan large objects and create models for printing, such as people, chairs, and desk.
The 3D printer is available for use by all University of Akron students, faculty, and staff. Printing is done on a first-come first-served basis taking into account that students who are printing design projects or class projects get top priority.
Bierce Library provides this service for all University of Akron's current students, faculty, and staff for FREE.
File Format: To print a model on the MakerBot 5th Gen, it must be exported as one of the following formats .stl, .obj, or .thing files. Most programs and object repositories can save or export in these formats.
Dimensions: The 3D model must fit within the build platform of the MakerBot 5th Gen, which is 25.2 x 19.9 x 15.0 cm (9.9 x 7.8 x 5.9 in)
The first step is to design a 3D object using a computer-aided design software program. Examples and links are provided under the "3D Design Software" tab. Secondly, users will need to submit the files in a .stl, .obj or .thing format in order for the MakerBot 5th Gen printer to read the files. If you prefer to not design your own 3D object, there are sources available to find already designed objects ready for printing. Sources can be found under the "Browse 3D Objects" tab.
The length of time for printing varies on the size and infill of your object. An intricate, highly detailed piece will take longer, while small uniform prints will take less time.
For example, if your object is small and has an infill of 10% it could take 30 minutes to an hour to print. If your object is large, 100% infill, and has multiple elements it could take up to 12+ hours to print.
*All of our objects are printed with 10% infill unless requested otherwise.
