The Library now offers 3D printing to all library users as a pilot service. We can help you print three-dimensional objects in plastic from the file you provide. Please note that our 3D printer doesn’t create industrial quality products. 

Printer & File Specifications

Printer modelCreality CR-10S PRO
Nozzle diameter0.4mm
Filament1.75 mm PLA filament
ColorSingle color printing in white, black, or blue
File formatFile with STL extension
Product dimensionsMaximum 300 (W) x 300 (L) x 400 (H) mm
Resolution0.2 mm per layer

Cost is HK$ 1.00 per 200 mm of filament, with a minimum charge of HK$ 20.00.

For example, a model that uses up…

500 mm of filamentcharges at HK$ 20.00 (minimum charge)
4,000 mm of filamentcharges at HK$ 20.00
4,001 mm of filamentcharges at HK$ 21.00 (round up to the next dollar)

Refunds are not offered for any of the following reasons:

  • Print problems or failure caused by the print file or model design.
  • Printed objects are not collected within the designated period.
  • Routine and small surface defects including bumps or holes.

Turnaround Time

Printing times vary based on the print queue, object size, design, and complexity. Please submit your file at least 2 weeks prior to the date needed. You will receive an email when the object is ready for collection. 

Submit a Request

  • Read all guidelines here before submitting your request.
  • All requests should be made through this online request form.
  • We will email you with a cost and turnaround estimate in 3 working days.


  • If you are okay with the cost and turnaround estimate, please print the email and bring it to the User Services Counter (L3) to settle the payment.
  • Counter staff will collect your email printout and issue a receipt to you.
  • Without your confirmation through a payment, your file will not be printed.

Object Collection

  • We will email you again when your object is ready for collection.
  • Please bring your staff / student / library card and the receipt to the Multimedia Learning Center counter (L4) to collect your object within 14 days.
  • We may dispose the uncollected object after this period.


It is not permitted to use our 3D printing service to create objects which are:

  • In violation of copyright or intellectual property rights.
  • Unsafe, harmful, dangerous or considered by library staff to pose an immediate threat to others.
  • Considered by library staff to be obscene or otherwise inappropriate for the academic environment.
  • For commercial use.

The Library reserves the right to refuse any 3D print request. Requesters are also fully responsible for any legal consequences arising from the printing or objects. 

Important Notes

  • The Library cannot provide any 3D modeling software or consultation service at the moment. You may refer to the FAQ for useful resources available online.
  • Print quality and functionality are not guaranteed. Refer to our refund policy.
  • For safety concern, library staff will print the file for you.
  • Due to the instability of the current printer, we cannot process print jobs that take more than 8 hours to complete. If you need to print a large object, you may consider separating your model into several smaller ones.


3D printing is the process of making a three-dimensional object from a digital model. 3D printers lay down heated plastic in layers to create objects. With this technology, you can create prototypes, replacement parts, and final products. You can print objects from a self-created model, 3D scan, photographs, purchased models, or free-to-use 3D models.
