3D Printers

    3d printer

    3D printers could create a physical object from a three-dimensional digital model, typically by laying down many thin layers of a material in succession.


    The printers are exclusively available for current NCKU students and faculty members. To access the printers as an outside member, please contact the manager to receive a price quote.

    Access Procedure

    • Prepare your model by following the instructions in the File Preparation section.
    • Reserve a time slot with this page.
    • Bring your 3D model to Raccoon, and discuss the slicing detail with the lab assistants.
    • Calculate the printing fee and pay.
    • Once the printing is finished, assistants will notify you to collect the print parts.

    Access Procedure – Self-Service

    3D printers are available for self-service for those who meet one of the following requirements:

    • Current or previous workspace assistants.
    • Completion of a qualifying 3D printing training course, such as ARCH3030E-CAM.
    • Demonstration of previous experience or competence in 3D printing.( Must be approved by the manager)
    • Other cases approved by the working space manager.

    Self-service printing is priced the same as regular printing. Schedule your printing using this page. Note that some printers are located in the badge-controlled area, so be sure to begin printing during open working hours.


    The printing material is limited to white PLA provided by Raccoon.

    Machine Status and Work Area

    File Preparation

    1. Check if the geometry is closed.
    2. Check if the thinnest part is not smaller than 0.8 mm. Otherwise, it won’t be printed, or it might lead to a poor printing result.
    3. When necessary, split the geometry into multiple parts, and orient the parts to their ideal printing direction.
    4. Arrange the printing parts on the printing bed. A dense arrangement could reduce the traverse time of the print head, thus reducing the total print time.
    5. Export the geometry in STL or OBJ format.


    If not specified otherwise, the assistant will use the latest CURA with the following settings to calculate the material usage.

    • Layer height: 0.2 mm
    • Building plate adhesion: Raft
    • Wall: 2
    • Infill: 10%
    • Support: if needed

    The fee is calculated with the following rate:

    • Current students and faculty members of Dept. of Arch: NTD $2 per gram.
    • Current students and faculty members of NCKU, Alumni of Dept. of Arch: NTD $3 per gram.
    • Other: NTD $5 per gram.

    If a failure-prone problem of the geometry is identified by the assistants beforehand, yet the user insists to go on printing, the material used by the failed printing will then be charged.

    Consulting the lab assistant before printing will be very helpful if you have no experience in 3D printing.
