3D Printing


The Manassas Park City Library has a MakerBot Replicator + for 3D printing service. We use PLA filament for all 3D print requests.


Our 3D printing service is an introduction to additive manufacturing technology for hobby-level experiences. We will do our best to accommodate your requests and specifications though we cannot guarantee a particular level of precision. The 3D printer may be used for lawful purposes only. Patrons will not be permitted to use the printer to create objects that are:

  • Prohibited by local, state or federal law.
  • In violation of another’s intellectual property rights; for example, materials that is subject to copyright, patent or trademark protection.
  • Unsafe, harmful, dangerous or that may pose an immediate threat to the well-being of others; for example, guns, knives or other possibly lethal weapons.
  • Obscene of otherwise inappropriate items for the Manassas Park City Library environment.

3D printing at the Manassas Park City Library will cost $.10 per gram including the weight of support, rafts and fillers.

3D print objects must be smaller than: 295 mm (x-axis) X 195 mm (y-axis) X 165 mm (z-axis), or approximately 11.6″x 7.6″x 6.5.″

xyz axis

Objects are printed in single filament color with a MakerBot Replicator. Items printed from the 3D printer, that are not picked up within seven days will become the property of the Manassas Park City Library. Items must be picked up by the individual who printed them. A requesting patron who does not pick up their print forfeits all future rights to use the 3D printer.

Not all designs can be printed as originally submitted. Upon review, staff may request that designs be modified and resubmitted in order to print. Such modifications may include (but are not limited to): scaling, grouping, and dividing parts.

Jobs exceeding 8 hours may not be printed. Projects will be added to the print queue as they are received and reviewed. No guarantee of completion time is made.

Files should be in STL format (.stl).
We cannot accommodate requests for specific colors.
You will be notified by phone or email when your print is complete. You will have seven days to pick up the item.



  • We recommend Tinkercad, a free, web-based 3D design tool for beginner designers that includes lessons and short tutorials on available features. You will need a valid email address to sign up.
  • You also can try SketchUp and Blender. Both require downloading the free software. (SketchUp is only free when you are a student)
  • To fix 3D design files, consider using free open-source repair software tools like Autocad Meshmixer and Blender.
