FAQs - General Printing
Software and Models
What types of files can you use? Our printers work with .stl files and .obj files. They cannot print .mesh files.
What is support structure and why do I need it? Support structure is the printer’s way of adding material so that each part of the model is supported. Everything is built from the ground up, and models with too much overhang do not print correctly without it. The more support structure, the more fragile the model, and the more likely the printer is to jam.
MakerBot Print is requiring a username and password? You can create your own username and password to use both in the library and at home.
Where can I find models to print? Models can be found on a variety of websites. The library recommends .
How can I make a model to print? Models can be made using any number of 3D modeling software. A simple web based program is . Library computers have 123D loaded on them for your use. Blender is also a free 3D modeling software that you can download.
When I loaded my model, it was the too big or too small. Can I resize it? Yes, MakerBot Print has a scale button on the top righthand side. Select the model that you want to resize and scale by percentages or mm. Be sure the “Uniform Scaling” box is checked. Be aware that scaling a small model significantly larger causes imperfections in the model to be more pronounced and often causes the printer to error.
What materials can I use to print? Our 3D printers only work with PLA plastic.
What colors can I print? The library has a wide variety of colors available for you to choose from. They are available in the FabLab.
Can I print in more than one color? Our printers only print in one color at a time. You can stop the print, change the color, and restart the print if you desire.
Can I get help printing? Yes, the library offers weekly open hours for teens 12+ and adults where you can get assistance with 3D printing.
My child is under 12, can they do 3D printing? Yes, we welcome you to come with your child during adult FabLab open hours. You can learn 3D printing together.
I’m not able to attend open hours. Can I still get training in using the 3D printers? Yes, please email . We will try to find a staff member or volunteer to assist you.
Does it cost to print? At this time, 3D printing services are free to the public.
How did the printers get their names? The 3D printers were purchased with grant money for the teen department. The Teen Advisory Board named the printers.
The Printer says the Smart Extruder has detached. What do I do? First, pause the print job. Unload the filament, load the filament, and restart your print. If that doesn’t solve the problem, email and library staff will respond to your issue in one business day.
The printer gave me an error message. What do I do? Email and library staff will respond to your issue in onebusiness day.
My completed print is very fragile, not smooth, or has strings hanging from it. These types of errors occur when the model was resized significantly larger, when it has too much support structure, or contained too much detail in too small of an area. Please review your model and make appropriate adjustments before trying again.
