- MUST click "submit" to submit the print job detail form.
- Wait for staff to review your print job and update your print job status. You will need to have the approve status for each print job in order to print.
(We will open your .gcode.3mf file to see if there's any slicing problem that clearly leads to print fail. e.g. no support on the part that MUST need support, wrong Bambu Printer version or plate type selected)
(We will update the status to "Required Modification from User" if there's any slicing problem)
- It is possible that if you have accumulate some print jobs without any slicing problem, after sometime, your print job will be auto approve by system. However, if you create any mess up situation in 3D Printer due to slicing problem in your future print job, you will need to wait for the approval from staff again.
- Make sure you have enough credit for the printing, otherwise you cannot start your print job. Our current rate is 1 gram = 0.1 credit

Tasks to do
For how to export a .gcode.3mf file, please refers to the above "Self-service Bambu printing system detail step" → "Preparation" part.
Submission method:
- Go to https://sdfablabhub.designandmake.org/, Choose 3D Print > New Print Job
- Create a new print Job for each Task 1-3 (each person), Task 4 submit only one for each group.
i.e. for a group of 4 ppl, I need to see 13 print job submitted for their group account. - Fill in your sliced capture and plate sliced file according to the task requirement. (For Task 3 the sliced capture is different, please pay attention for the requirement)
- Fill in the rest of the information. Choose Matte PLA, Subject Use, and fill in your own subject code(May not be SD4410). Click submit.
- Go to the detail page of the print job you just submitted
- Check the detail, make sure you submitted the correct file. If you need to make changes, click "Edit"
- Scroll down to the bottom of the page, reply the text required by each task. e.g. for Task 1, you will need to reply "Task 1, group member no. {Your group member no.}, {Your English Full Name}". It is your group member number, NOT your group number.
Orientation

Submit a ScreenOrientation
View file name Task1.3mf height 250 Instruction:
Submit a Screen capture of the whole window, and a .gcode.3mf file with sliced models in Bambu studio. The orientation MUST need to be fixed so that it doesn't need any support in order to print the objects.Submission required:
a. Add heading Reply "Task 1" before your attachments, group member no. {Your group member no.}, {Your English Full Name}".
b. One modified .gcode.3mf file
c. One screen capture of the Sliced View showing support option enable but no support generated with correct orientation of the objects (Whole window screen capture in Preview session).Sense of selecting support
Decide which is the best printing orientation by adding the support.
Original File:
View file name Task2.3mf height 250
Correct answer: (support should be less than 0.5g)Instruction:
Submit a Screen capture of the whole window, and a .gcode.3mf file with sliced models in Bambu studio. Must use tree(auto) support mode, and need to select an extra option for the support, the best orientation should be less than 0.5g support. The surface of the bolt pattern is functional, so it must remain smooth, and must keep the original shape after printing.
Submission required:
a. Add heading "Task 2" before your attachmentsReply "Task 2, group member no. {Your group member no.}, {Your English Full Name}".
b. One modified .gcode.3mf file
c. One screen capture of the Sliced View showing support option enable and selected tree(auto) mode with option selected (Whole window screen capture in Preview session).Spherical print
Instruction:
Find a 3d model on the internet, with spherical structure.
Look at Variable Layer Height | Bambu Lab Wiki for reference, apply variable layer height to your 3d model, you can use either adaptive or smooth. Apply suitable support structure as well (depends on your 3d model).
Screen capture the sliced view with color scheme as "Layer Height" just like the following picture.
Submission required:
a. Add heading Reply "Task 3" before your attachments, group member no. {Your group member no.}, {Your English Full Name}".
b. One modified .gcode.3mf file
c. one One screen capture of the Sliced View showing the the color scheme as "layer height", with suitable support structure apply to the sliced 3d model (Whole window screen capture in Preview session).Hole Tightness
View file name signal-2025-02-02-220739_003.mp4 height 250 Provided Material:
Please choose the corresponding base according to your number of group members (At least 2 ppl in a group)View file name Task4Base_4ppl.stp height 250 View file name Task4Base_3ppl.stp height 250 View file name Task4Base_2ppl.stp height 250 Instruction:
Printing file parameter limitation:
Number of group members 4 ppl 3ppl 2ppl Model Total Printing Time
(including preparation time)<1 hr <50 mins <40 mins Filament Estimation (grams) <18 <12 <8 If you submit a print file that is out of these range, I will request for your modification.
You should use the Task4Base_{}ppl.stp as the base, and draw the other missing parts by yourself.
You need to add hole for different layer:
First layer (the top prism in the sample):
The cylinder for first layer have radius of 1.5mm, as the prism should tightly fit to the cylinder, the hole should have 0.1mm extra in radius, which means the hole should have 1.6mm in radius, with 5mm as height.
Actually it do not needs to be a triangular prism, as long as it have the hole in correct size. This layer is just for preventing the layers fall off. However, please be remind that a complex shape will increase printing time, and use more filament.Second layer to fifth layer:
Number of group members 4 ppl 3ppl 2ppl Number of layers 4 3 2 Height per each layer piece 10 mm Total cylinder height 40mm 30mm 20mm The cylinder have radius of 2mm, as the polygon prisms should have a little bit loose in order to make it spinnable, the hole should have 0.2mm extra in radius, which means the hole should have 2.2mm in radius.
The height for each layer is 10mm.
Cylinder height for 4 ppl is 10 * 4 = 40mm. (So 3ppl is 30mm... and so on)For Each layer:
Can be any sided polygonal prism, it is formed by a polygonal prism minus a smaller polygonal prism so that it is hollow, and union with a tube with the 2.2mm radius hole.
The height must be 10mm.
Sample for forth layer:
You also need to add 3D letter on top of the side surface.
The letter should align with the side surface, and must be consist of 5mm in height and 1mm in width in order for it to print clearly.
The sliced view must look like this in order for the extruded letter to print correctly.Required letter for layer except bottom layer:
First letter is your group member number submitted in the google sheet. If you are the no.1 in group, you should have your first letter as "1".
Starting from second letter, it would be your English Full Name initial. e.g. LCM stand for Lau Chiu Ming, and he is the no. 1 in group.
Bottom layer:Include your subject code (e.g. SD1105 should be "1105") at first surface (or first two surface depends on if there's not enough space).
Then the next surface should be your group number. E.g. group 1 should be "G1", group 2 should be "G2" and so on.
The next is the same as the other layer, your group member number and your English Full Name initial.
(For group of 2 ppl, the surface of each side faces may only enough for single letter, you can spread the subject code on the bottom layer, and the group number on the layer above. i.e. second layer: "G" "2" "1" "L" "C" "M", third layer: "1" "1" "0" "5" "2" "H" "C" "F")
Each group should submit 1 set (assembled), each person should make 1 layer piece.Extra (for student who like to challenge):
You can draw star shape instead of regular polygon, but keep in mind that the extruded letter should not be floating (no empty space between the letter and the intersection area of two surface).
Submission required:
a. Add heading "Task 4" before your attachments.
b. (In Print job form) Submit the print job using your group assigned account. Go to https://sdfablabhub.designandmake.org/, Choose 3D Print > New Print Job.required:
a. Reply "Task 4, group member no. 1, {English Full Name}, group member no. 2, {English Full Name}, group member no. 3, {English Full Name}, group member no. 4, {English Full Name}" *according to how many group members you have
b. Submit the print job for only ONCE per each group.
Fill in all the required detail. Your modified .gcode.3mf file should have all the parts in one plate, and set the print sequence to "By object", enable "tree(auto)" support.
Make sure the filament amount and printing time is within the limitation mentioned above.
c. (In Print job form) One screen capture of the Sliced View WITH Total printing time and Model printing time shown (Whole window screen capture in Preview session). If there's support, capture should show support section.
d. (In V104) After admin approve your print job, you can then go to V104 to send your print job to the available printers according to your group assigned timeslot. Assemble your print, and then put it into the corresponding submission box right next to the printer according to your subject code. . Admin will add credits to your group account before your assigned printing time slot.Printing time slot Group No. 1 - 12 13 - 24 25 - 36 SD4410 Feb 10-23 - SD5978 Feb 10-23 - - SD5512 Feb 10-23 - - SD1105 Feb 24- Mar 9
