To meet the diverse needs of teachers and students across the university in scientific research, course practice, and creative design, our library has integrated existing equipment resources and officially launched a 3D printing service reservation channel. To ensure fair and orderly service and improve equipment utilization efficiency, the specific reservation process, usage regulations, and related notices are as follows:

Service Location: Maker Space, 2nd Floor of the Library；

Reservation Review Email: library_noreply@cityu-dg.edu.cn;

Available Machines: Raise3D E3, Raise3D Pro3 Plus, Bambu Lab H2D;

Eligible Users: Registered students and faculty on campus。

1. Reservation Rules
Access the reservation page via the link above; reservations must be made at least 3 days in advance. Public holidays: reservations are suspended. A maximum of 2 reservations per week, with each session lasting no more than 5 hours. After reserving, submit the 3D model file for printing to the designated email for review. Only STL format files are supported, and the file should include an estimated material usage and printing duration for this print. The system will review submissions within 2 working days; upon approval, a “Reservation Successful” email will be sent. To cancel or modify a reservation, campus users must do so at least 24 hours in advance through the platform. Failure to make timely changes or show up for the scheduled print will be considered a “no-show.”

2、Usage Regulations

Consumables are provided by the management. The types and colors of consumables can be viewed on the library's digital resource management interface. Each person has an annual free quota of 80g; for special consumables (such as colored PLA, flexible resin), they can be provided by the management or brought by users themselves. Before use, users must submit a sample of the consumable to the administrator for compatibility review. Only after passing the review can the consumable be used.

 3、Prohibited Printing Situations

1) Items involving illegal or prohibited substances (such as replica weapons, controlled knives, flammable and explosive structures);

2) Items infringing on intellectual property rights (such as unauthorized brand logos, copies of patented products);

3) Vulgar, violent, or items that violate public order and morals;

4) Items with unstable structures or that may cause equipment failure (such as unsupported hanging structures, excessively thick models).
