Bambu Lab P1S 3D Printer Review

Bambu Lab is a new company that has become popular in the 3D printing scene. Today, we will discuss one of their offerings in our Bambu Lab P1S 3D Printer Review.

The company became a hit after offering 3D printers that create top-quality results perfect for experienced users and novices. The P1S is a 3D printer that is cheaper than the popular X1 Carbon. 

How does it fare and perform under different scenarios? We tested it for our Bambu Lab P1S 3D Printer Review to see if it operates as it claims. Aside from its performance, we will also share details about its functions, design, features, and specs. 

But now, what is inside the box?

Bambu Lab P1S 3D Printer Packaging

The Bambu Lab P1S shipped in a sturdy cardboard package that arrived unscathed. Nestled within custom foam cutouts are the P1S unit and the AMS component.

To save on space within the box, the AMS settles within the confines of the P1S chamber. Getting all the items out took us some time. We had to unscrew some areas that only existed to secure everything during shipping. 

When you open the package, you will find these items: 

  • Bambu Lab P1S 3D Printer
  • Stainless Steel Hotend with nozzle
  • Unclogging Pin Tool
  • Build Plate
  • Power Cable
  • Bambu PLA Filament
  • Accessory Box

The packaging includes the P1S Combo Add-ons, which we will also list in our Bambu Lab P1S 3D Printer Review. 

  • The Bambu Lab AMS, which is in the chassis of the PS1 3D Printer
  • Bus Cable 6-Pin from Bambu
  • Spare Filament Cutter (x2)

Bambu Lab P1S 3D Printer Review – Design and Functionality

In this Bambu Lab P1S 3D Printer Review, we will discuss the budget version of the X1-Carbon 3D printer. The P1S is fully enclosed with plastic sides and sports a D-pad selector interface like the P1P. 

This product is a 3rd CoreXY printer that integrates the same elements as the pricier version. These include build volume, motion system, quality, and speed.

CoreXY printers use bells to move the X/Y axis simultaneously for faster and smoother printing.

The printer head remains at the top of the product while its build plate lowers. You will get high-quality prints when this motion combines with the vibration-damping input shaping. 

The auto bed levelling system of the printer offers an initial layer without requiring adjustments to the z height. After a quick automated calibration process, the P1S transitions into operation.

The P1S is a fully enclosed unit featuring sleek black plastic side panels. It has smoked glass elements for the upper section and its door. All the components of the P1P remain on this printer, like its speed and unparalleled accuracy. 

All the optimisations integrated into the P1S are what users felt the P1P should have had since the beginning. 

Another enhancement of this model is a durable fan for cooling parts quickly. It is essential for fast 3D printers since plenty of hot-moving material can warp the model weirdly. 

Additionally, it has an LED light strip and camera for recording timelapse videos you can post to TikTok, Instagram, etc.

Bambu Lab AMS (Automatic Material System)

The huge advantage of the P1S is its compatibility with the Automatic Material System or AMS. Our Bambu Lab P1S 3D Printer Review will discuss this system and how it works. 

The AMS is an add-on system like the Prusa MMU (Multi Material Upgrade). It is not an inclusion when buying the P1S but is available in a combo package or separate purchase. Also, you can place the AMS next to or on top of the P1S.

For its functions, it is a four-spool feeder that enables printing in four to sixteen colours. The AMS allows the printer to switch between filament spools in the middle of printing. Note that one AMS lets you swap between four filament spools.

This system can read and identify RFID tags of Bambu Lab spools. When you install a filament, the RFID tag provides data to the printer, including material type and colour. The printer matches this information with presets in the Bambu Studio software.

If you want to use third-party filaments, it will work with the P1S. However, you must provide the material information manually since these do not have RFID tags from Bambu Lab.

The AMS also features pockets for descants, which seal tightly. As a result, you can use the AMS as a dry box for nylon and similar filaments.

The AMS also has a backup option, allowing it to switch from one slot to another automatically. Tripping a run-out sensor is unnecessary. It will also be excellent for using partial spools or when your model needs more than one spool.

Key Features of the Bambu Lab P1S 3D Printer 

What makes the P1S a better option than other 3D printers? To give you an idea, we made a list of its features in our Bambu Lab P1S 3D Printer Review.

This feature allows you to enjoy consistent and precise extrusion for no-blur, smooth prints. 

Succeed and Acquire a Perfect First Layer

The P1S features an auto bed levelling (ABL) sensor that adequately levels and calibrates the bed. Doing so gives you a precise first layer for each 3D print. 

Power-loss Recovery 

If there is a sudden power cut-off, you will not need to worry because of this feature. Power-loss recovery will allow you to resume your printing activity from where you left off. 

All-metal Hotend of the Bambu Lab P1S 3D Printer

Bambu Lab uses durable materials for supporting long-time 3D printing filaments like carbon fibre and ABS at high temperatures. It gives you precise and seamless extrusion to acquire top-notch printing performance. 

Fans Featuring Speed Feedback

The fans of the P1S have these sensors to monitor its speed to ensure it can operate at optimal speeds every time. 

Filament Run-out Sensor of the Bambu Lab P1S 3D Printer

With this feature, you can eliminate empty spools during printing. All you need to do is change the filament when necessary and resume working. It is straightforward without the hassles. 

Semi-auto Belt Tensioning

Belt tensioning is essential to guarantee dimensional accuracy. In addition, it runs resonance frequency identification to help keep the ideal level of tension. 

Bambu Lab P1S 3D Printer Live Viewing and Timelapse

The P1S has an integrated chamber camera, allowing you to monitor your print via Bambu Studio and Handy. Plus, you can create a timelapse video of the printing process.

Bambu Lab AMS 

Bambu Lab allows you to print with multiple colours and materials with its Automatic Material System. It is an excellent add-on to the P1S since it has many impressive features to enhance your 3D printing experience.

Print with Multiple Materials

AMS is highly versatile and works with many filament types, including ASA, ABS, PETG, PLA, PC, etc.

Convenient Support Removal

With AMS, the P1S can use dissolvable filament or snap-away support material. It helps reduce the hassle of removing supports.

No Leftover Filaments

Manually Replacing spools disrupts printing when you do not have AMS, resulting in wasted filaments. AMS makes transitioning to a new spool seamless and convenient to prevent wasting material.

Filament Backup for Uninterrupted Printing

Printing never stops, thanks to automatic spool changing. AMS has a filament backup function to keep you worry-free from running out of material. Printing is seamless and uninterrupted, preventing wasted filaments while promoting energy efficiency.

Advanced Intelligent System

AMS uses a 32-bit MCU, actuators, sensor arrays, and an intelligent algorithm. As a result, it can handle filament loading and unloading, detect faulty printing, and recover prints.

Filament Winding Detection

Tangled filaments or stuck spools can cause the material at the tool head to encounter resistance. AMS can detect this instance immediately and suspend printing to prevent empty prints.

No More Wet Filaments and Failed Prints

The AMS’s air-tight seal and desiccant material absorb moisture to prevent wet filaments and print failure.

Automatically Identifies Bambu Lab Filaments 

Filaments from Bambu Lab feature an RFID for the AMS to detect. It automatically synchronises to Bambu Studio for more convenience.

This part of our Bambu Lab P1S 3D Printer Review focuses on our hands-on experience with the printer. We used it for two weeks to test and print various items. 

The printer comes pre-assembled and only requires unpacking and attaching the spool holder and the control screen. Afterwards, you will receive a walkthrough to help you through each step.

The setup process was intuitive and easy, and its instructions were clear. The process was straightforward, like setting up a TV set, so newbies would not have troubles here.

Moreover, the printer has a fantastic auto levelling system with vibration compensation, semi-auto and pressure-advanced belt tensioning. We did a thorough self-test after unpacking the P1S to ensure everything worked. 

When the printer is up and running, it automatically starts a bed levelling check during each print. It usually lasts about six minutes, but you can skip it if you do not want to.

It is not necessary to set the z height/z offset. Plus, there is no option/button to do so since the P1S can handle the settings. 

Bambu Studio is the custom slicer for the P1S and resembles PrusaSlicer. If you have used Prusa before, the interface will be highly familiar. Based on our experience, the presets for all filament types were easy to use. 

Bambu Slicer works with other printers, including Creality, Elegoo, Anycubic, and many other brands. It also has a growing list of presets for these 3D printer manufacturers.

The default profiles worked excellently and were easy to use. Advanced settings are also available, including fuzzy skin, tree supports, and everything you expect in modern slicers.

After setting up WiFi on the P1, Bambu Studio offers more features. It allows you to manage the printer and the AMS, view the live video feed, and manage timelapse recordings. You must remove the SD card from the printer to access the recordings.

In addition, you can also colour your prints via  Bambu Studio. It features a standard painting program, and it does not require professional designer skills to use it. 

The device tab lets you send files via WiFi, remotely tweak the printing speed and temperature, and watch timelapse videos.

It is also possible to save complex builts via project manager, letting you create one shareable 3mf file. The latter can include several plates of photos, build parts, and bills of materials. 

We were surprised by its multi-material painting tools. These let you take standard 3D models to paint colours and use various materials.

The Handy app is more straightforward than the Bambu Studio but has numerous functions. It provides AMS information and offers viewing of the live video feed via your phone. Plus, it has standard controls like pausing or stopping a print.

Handy was highly convenient when we needed to monitor the progress of prints while we were away from the P1S.

Before printing, the P1S performed self-checking and automatic levelling. Unlike with other 3D printers, we did not need to place a sheet of paper under the nozzle. We also did not adjust any settings since the printer did everything it had to do before producing prints.

The self-checks and levelling took around five minutes, but it was worth the wait since it made our 10-hour prints successful. The auto-levelling offered a perfect first layer, which made working with any layer thickness easy.

In our experience, the P1S was excellent, and its performance could match FDM and FFF 3D printers. Its efficient operation and print quality beat other similar products.

As we mentioned, we did not tweak any settings, but the printed models were perfect. It also performed with high speeds and minimal vibrations, thanks to the CoreXY Kinematic System.

Prints were incredibly fast and the printer operated very quietly when compared to other high speed printers.

We found that the auto leveling was spot on, with the first print layers being perfect. We were incredibly impressed as the quality of each layer and how good adhesion was.

The prints stuck firmly to the print bed when printing, avoiding any issue with prints slipping or moving. We were very surprised at how easily the prints came off the build plate when the prints were finished. Much better than any other printers we have used before.

Another thing that surprised us was just how well finished the prints were. We were expecting for there to be texture to the prints from each layer (as is common with 3D prints), however the prints were completely smooth. There was no finishing that we needed to do to a print once it had completed.

This truly is an impressive printer!

The AMS performed perfectly when we did test prints. It worked perfectly for producing multi-coloured models and as a support material. 

One of the unique features of the AMS that impressed us was the RFID spool detection. The P1S immediately recognised the colour and material of the Bambu Lab spool since it had an RFID tag. 

We also saw the material in each slot of the AMS, and we used it to set up a print. AMS also used the print identifier to monitor the remaining amount of filament on each spool.

As we mentioned, AMS is not only for multi-coloured prints. It was also handy as a spool holder that helped save time since we only had to swap colours once. We did not have to run eight batches on a single-colour machine, making it less wasteful.

Bambu Lab P1S 3D Printer Review Summary

The P1S has similar platform-wide specifications as the Bambu Lab P1P and X1 Carbon 3D printers. It also uses the same software & cloud ecosystem, delivers industry-shifting performance, and integrates seamlessly with the AMS.

We had an excellent user experience when we tested this product for our Bambu Lab P1S 3D Printer Review. One reason why we loved this 3D printer was its user-friendliness. It had an automatic levelling system, so manually doing this was unnecessary, and it also had an intuitive companion software. 

Aside from being easy to use, it produced high-quality prints using different filament types. Some required minor adjustments on the printing speed, but these were easy since the printer and software are user-friendly.

We highly recommend the P1S since it has an enclosure and regulated chamber for more material options. It is also best when used with the AMS. Learn more about the P1S 3D Printer when you visit the official product page of Bambu Lab.
