Preparing your 3D print file: Please save your file in STL format on a USB thumb drive. You can create your 3D model from scratch or download a file ready for printing on the Internet. You are suggested to scan your file at this Microsoft website on 3D printing to make sure the file is printable and to fix any problems that may cause the model to print incorrectly.

Making an appointment: Two sessions are available every day from Mondays to Fridays (except weekends and public holidays) at 10:00 - 10:30 a.m. and 3:30 - 4:00 p.m. You may make an appointment 3 days in advance on iBooking  where you can select your preferred day and time.

Service location: Bring along your STL file saved on a USB thumb drive and place your print request with our staff at Poster and 3D Printing Room (Room L303M) in 3/F Multimedia Commons.

No show policy: Your booking will be automatically canceled 15 minutes after the appointment time begins. If you are unable to come, please cancel your booking as soon as possible so that another user can get an opportunity to use this service.

Placing a print request:

  • You will be required to fill in and sign a print request form indicating all the printing requirements.
  • Library staff will go through your print file with you on a 3D printing workstation where you can configure the printing parameters and requirements (such as layer height, in-fill, support, etc.).
  • Library staff will then assess the printability of your file and indicate the printing time and cost on the request form.
  • You will be required to pay for the printing cost in full at the time your printing request is placed.

Printing time:  It depends on the size and complexity of the model. Our printer may take one hour to print a model weighing 10 grams.

Picking up your printed model: You will be given an expected date and time for pickup after placing your request. You are suggested to call 2766-6909 to make sure the printed object is ready for pickup beforehand.
