Timelapse photography is a shooting technology that compresses the process of minutes, hours or even days into a shorter period of time and plays it as a video.
¶ 1. Introduction to different modes of time-lapse
In the Bambu Studio, if you enable timelapse, a timelapse video will be generated for each print. After each layer is printed, a snapshot is taken by the chamber camera. All of these snapshots are composed into a timelapse video when printing completes.
There are two modes of timelapse: smooth mode and traditional mode. For different printers, there will be some differences in the action of shooting time-lapse photography, which is described as follows.
¶ X1 and P1 series printers
Smooth mode: the tool head will move to the excess chute after each layer is printed and then take a snapshot. Since the melted filament may leak from the nozzle during the process of taking the snapshot, a prime tower is required in this mode. So a prime tower will be automatically generated if there is no prime tower on the build plate. It will reuse the existing prime tower if there is already a prime tower on the plate.
In this mode, the toolhead in the video always stays above the prime tower and does not block the model. Therefore, the timelapse video looks very smooth. However, the overall print time will be longer because this mode adds additional paths and nozzle cleanings to the toolhead.
Traditional mode: It takes a snapshot directly after each layer is printed, so there is no need for a prime tower in this mode. In time-lapse videos, the toolhead is constantly moving.
¶ A1 Series Printer

The X1 and P1 series printers only move the heat bed up and down when printing, and it change its position in the Z direction by moving the heat bed. Due to the different structure, the A1 series printer changes its position in the Y-axis direction by moving the heat bed back and forth, so the heat bed moves continuously in the horizontal direction during the printing process.
When shooting the time-lapse video, it is necessary to keep the horizontal position of the heat bed fixed and only change the position in the Z direction. However, the A1 series printer's heat bed was constantly moving during printing, causing the model to move horizontally as well. So, to successfully shoot time-lapse videos, the A1 series printer moves the heat bed to a fixed position and the nozzle to the purge wiper before each shooting then moves them back above the model to continue printing. Whether it is the traditional mode or smooth mode time-lapse photography, it will move the heat bed and tool head to a fixed position before taking the photo. You can see the moving path to the purge wiper in the traveling path previewed after slicing (see below), but if you do not enable the time-lapse feature before sending the print job, these moves will not be executed during the actual print process.
Traditional mode: During the printing process, due to the leakage caused by the pause when taking the snapshot, the traditional mode of time-lapse photography does not have a prime tower to absorb this flaw, affecting the printing quality. So our strategy is to print defects into the infill as much as possible to ensure surface quality, but if the model has no infill area in this layer, defects are inevitable. In this case, it is not recommended to enable time-lapse photography in traditional mode but to use smooth mode. You will also receive a prompt before sending the print job.
Smooth mode: After selecting smooth mode time-lapse photography, a prime tower will be automatically generated by default. During the printing process, after pausing to take photos, the nozzle will print on the prime tower first, and then continue to print on the model, so that the leakage defects caused by the pause are absorbed by the prime tower.
Below is a comparison of print quality between traditional time-lapse and smooth mode time-lapse for an unfilled model:
Timelapse Fade-on Mode: When this mode is turned on, a cropping effect will appear when printing the first layer. As the number of layers increases, the image gradually changes from zooming in to zooming out.
If the time-lapse Fade-on Mode is turned off, the zooming effect will not appear.
¶ 2. How to enable timelapse
In the menu bar, in the "Special Mode" under the "Others" option, you can find the "Timelapse".
When you select Smooth mode, make sure to enable the Prime tower (this feature is turned on by default), as we need the prime tower to clean the nozzle.
Before you start printing, make sure you have an SD card with enough memory space inserted into the printer and check "Timelapse" when sending the print job.
¶ 3. Where to get timelapse video files
After printing, the generated timelapse video will be stored in the printer's SD card. You can find timelapse video files in the "timelapse" folder on your SD card:
In Bambu Studio, you can also download timelapse video files from the "Device" - "MicroSD Card" page:
