We have categorized the FAQ of A1 mini into product specifications, product features, and product usage-related. You can quickly navigate to the desired module using the sidebar on the left.
The A1 mini can print most of the materials on the market that don't require an enclosure, such as PLA, PETG, TPU, and their support filament. It is not recommended to print filaments such as ABS, ASA, PC, PA, and PET that require higher bed and chamber temperatures.
The max hotend temperature is 300 ℃, and the max heatbed temperature is 80 ℃.
180 * 180 *180 mm. For more product specifications, please refer to this page.
The printer comes pre-installed with a 0.4mm stainless steel nozzle. Our official store will sell extra nozzles, including a 0.2mm stainless steel nozzle and hardened steel nozzles in 0.4mm, 0.6mm, and 0.8mm diameters. If you require them, you can purchase them from the official store.
In silent mode, the operating noise of the A1 mini is around 48 dB.
The A1 mini draws 6 W in idle mode and 57 W on average when printing. Much higher than that when printing and heating the bed and hotend from the ambient temperature.
Our printer supports the auto bed leveling feature. We suggest you check the heatbed leveling option before starting the print job. This way, the algorithm will quickly check five points to determine whether to level again or reuse the previous leveling data. There shouldn't be a need to level the heatbed manually.
We recommend enabling the auto bed leveling option for every print job because magnetic build plates will likely not be placed in the same position with perfect precision after each print. Additionally, before the auto bed leveling, the printer will quickly test five points to determine whether it needs to level the bed again or reuse the previous leveling data.
The hotend will sense the ripple of the extrusion force during purging at the nozzle wiper and calibrate the K value.
A partial nozzle clog may cause an incorrect K value. The good news is that future firmware updates will support manual flow dynamics calibration.
In the following cases, you will need to do the calibration ( but it's highly recommended to just keep it on for every print) :
No, the AMS lite filament hub is just a mechanical structure and does not include electronic components. It does not know which slot the current filament comes from. For the printer to know which slot the current material comes from, the printer itself will first check the position of the filament each time it loads or unloads the filament. For more detailed explanations, please refer to the AMS lite introduction.
The A1 mini printer has a 0.4mm stainless steel nozzle already mounted. To minimize excessive nozzle wear, using stainless steel nozzles for printing materials containing carbon fiber or glass fiber, such as PLA-CF/GF, PETG-CF/GF, etc., is not recommended. However, if you replace the nozzle with a hardened steel material, you can print with CF-based filaments on the A1 mini. If you wish to use A1 mini with the AMS lite, please also follow the AMS lite filament requirements.
No, AMS is incompatible with the A1 mini. If you want a multi-color print using A1 mini, you must use the AMS lite.
The recommended distance between A1 mini and AMS lite is 50mm as shown in the diagram.
The A1 mini can only support one AMS lite, which means it can print with a maximum of 4 colors.
This is an interface reserved for future product expansions and/or additional functionalities.
Insert 580mm PTFE tubes (shorter one) into slots 1 and 2 and 700mm PTFE tubes(longer one) into slots 3 and 4. At the same time, the other ends of slots 1 and 2 PTFE need to be inserted into the two slots on the left side of the filament hub, while 3 and 4 need to be inserted into the two slots on the right side of the filament hub. (Viewing the printer from the front to the back.)
The recommended ambient temperature of the A1 mini printer is 10-30 degrees Celsius.
The A1 mini supports both textured PEI plate and smooth PEI plate. A textured PEI plate is included as an accessory when you unbox the printer. If you wish to obtain a smooth PEI plate, you can purchase it from our official online store.
The textured PEI plate can print various materials, such as PLA, PETG, and TPU, without glue. After printing, please wait for the build plate to cool down completely before removing the printed model. It is advised to clean the build plate with warm water and regular soap to maintain optimal adhesion.
The smooth PEI plate has a flat surface and can print PLA/PETG/TPU. This printing surface is particularly suitable for printing PLA without glue. However, printing PETG and TPU requires the application of glue(liquid or solid).
No, the smooth PEI build plate sticker is not replaceable.
No, the A1 mini does not have built-in memory, so you must insert a micro SD card to send a print. The printer comes pre-installed with a 32 GB Micro SD card.
The A1 mini supports a micro SD card of up to 2TB if formatted using the printer option. Please refer to this page for more information about micro SD card-related FAQs. （will be added）
A flashing white LED indicates that there are AI assistant messages that need to be looked at; a solid white light means that the system status is normal.
You can set the print speed in Bambu Studio when slicing on the speed page. While printing, you can change the speed mode (Silent, Standard, Sport, Turbo) on the printer, Bambu Handy or Bambu Studio. It's important to note that Sport and Turbo require higher hotend temperatures for best results, and we recommend setting a higher speed in the slicer.
The A1 mini utilizes a filament hall sensor to determine if the filament has run out. The A1mini supports filament runout detection and can resume printing after filament replacement. When used with AMS lite, the A1mini can be configured to use a backup filament as a substitute after the current filament runs out.
After powering on the printer again, you can choose to resume printing after power loss, allowing the printer to continue and complete the previously interrupted print job.
Yes, you can turn off the sound in the printer settings.
Yes, pause at a certain layer height is available and can be done in Bambu Studio.
The accessories include a spool holder, which needs to be installed by the user upon unboxing.
We have a printing guide for TPU, and you can find more information in this document. Additionally, we recommend you refer to our filament guide to obtain more information on filament settings parameters.
Near the purge wiper - Left side (Thus avoiding waste or scaps getting onto the bed or z-axis and saving the toolhead's travel time during filament changes.)
We don't recommend enclosing the A1 mini.
Firmware upgrades will be published occasionally to add more features and patches to the software running on the machine. The printer will check for any available updates in the cloud and display a pop-up notification if there are.
Yes, the A1 mini supports auto-recovery from a step loss; you can enable this feature on the print options page.
If you find removing the PTFE tube from the tool head inconvenient, you can print this model to assist with the operation.
The sound effect can be turned off in 'Main menu - Settings - Print options'
