Materials Support


PLA (bio-degradable polymer)

PVA (supporting materials)



  • This service requires payment in advance and is available up to one hour before the Media Services office closes.
  • Create your 3D model from scratch or download a file ready for printing on the Internet.  Please save your file in STL format on a FAT USB thumb drive or online. 
  • Reserve a 3D printer workstation time slot through our booking system, or provide the STL file and pre-printing requirements by email. 
  • Library staff will run through your print file on a 3D printing workstation where you can configure the printing 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.
  • For RESIN printing, the 3D model must be cleaned and dried in post-processing, which takes an additional hour.
  • There is NO GUARANTEE that all items will print successfully even if the review indicates it might; this printing is a process subject to mechanical, heating, weather and other conditions outside of the Staff's control.
  • NO REFUND once a 3D print job is sent to print.
  • The Library reserves the right to decline a printing request or cancel a printing job if the object may infringe copyright or contain abusive constituents.

# Please note that the accuracy of FDM 3D printing with PLA is +/- 0.4~0.5mm.
