Usage procedure for trained members

  • Step 1. Booking required

    Before using our SLA 3D printer, please fill in the job registration form to make a booking reservation.

    The technical team will receive your reservation and contact you through email with an allocated timeslot for your SLA printing job.

    Please come to meet our technical expert in the timeslot assigned.

  • Step 2. Import the 3D model to slicer (.stl / .obj file)

    Use any object modeling software (e.g., Solidworks / Fusion 360) or download a 3D model online for printing. Prepare the object model in  .stl / .obj file format.

  • Step 3. Printing per configuration (.ctb file)

    Use CHITUBOX software to do pre-configuration of the print job. Do slicing and obtain the estimated printing duration and estimated material for the print job. Download the g-code file into a USB drive.

  • Step 4. Turn on and initialize the SLA Printer

    Please work with our on-duty technicians/tutors to turn on the SLA Printing, it will take about 5 mins to fill up the resin of the machine before it can be used.

  • Step 5. Start printing and post curing the model after it finished.

    After the model is printed, remove the support and wash away the unsolidified resin with 95% Isopropyl alcohol. Put into Luna Cure for 30 minutes to speed up the curing process and maximize the composite final material properties

  • Step 6. Switch off the machine and clean up the workspace for the next user

    Please switch off the machine after use.

    Please clean up the workspace for the next user.

    Place the used material board (if any) into the "Free to use" box.
