Bambu Lab A1 Mini

Bambu is often compared to Apple in the 3D printing world due to their high-quality and innovative products. They offer a wide range of printers, and the A1 Mini is an ideal entry-level model for the average FPV pilot, priced just under $300.

Despite its affordability, it retains many advanced features typical of Bambu Lab’s higher-end models, including high-speed printing, a direct drive extruder, and capabilities for multicolor printing, and it won’t force you to tinker and upgrade straight out of the box. It’s slightly more expensive than the Ender 3, but it runs out of the box and just easier to get started without modifications.

The printer is designed with a bed-slinger and cantilever structure, supporting various filament types like PLA, PETG, TPU, and PVA straight out of the box. It offers a build volume of 180 x 180 x 180 mm and includes quality-of-life features such as auto bed leveling, auto calibration, and a built-in camera for monitoring prints, though the camera quality is notably low.

Setup is straightforward, requiring minimal assembly, and the printer is equipped with Wi-Fi for easy control via app or software. While there are some compatibility issues with third-party filament spools for multicolor printing, the overall performance, ease of use, and print quality make the A1 Mini an exceptional value for those new to 3D printing or seeking a reliable, budget-friendly printer. The only reason one would still buy an Ender 3 would probably because it’s a good platform for tinkering and modifying. However as a beginner you should look a different way.

Pros:

• The A1 Mini is around $100 more than the Ender 3 V3 SE, but the additional features make it worth the price.
• Direct Drive
• Automatic bed leveling and Z-offset adjustment
• High manufacturing quality
• Excellent print quality and speed
• Wi-Fi/Cloud capabilities
• Prints twice as fast as the Ender 3 on PLA (less significant for TPU)
• Additional features: camera, end-of-filament detection, real-time flow measurement and compensation, accelerometer, active noise cancellation, touch screen, linear rails, textured PEI plate
• Superior customer support and after-sales service

Cons:

• Dependency on BambuLab for both software and hardware
• Cloud dependence. If their servers are down, printing is impacted, although users can manually copy files to the SD card or switch to local mode. However, this reduces the convenience of the printer.
• Smaller print volume of 18x18x18cm, which might be limiting for some users but is generally sufficient for printing TPU parts for FPV.

Creality, the maker of Ender, has been around for the longest time, and seems to have taken a backseat in innovation. On the other hand, Bambu has been constantly releasing printers for different audience, with different price range and features. For example, for those on a budget, the Bambu A1 Mini is worth a look. Ender 3 might still be the tinkerer’s choice, but for beginners, I’d steer towards something less demanding.

Take a look at the Bambu Labs P1S – sure, it’s more than you ever need for printing FPV drone parts, but the print quality and user-friendliness are undeniable. The more expensive Bambu X1C is nothing short of a dream. If you can afford it, a Bambu printer can deliver incredible results with less fiddling around.

Bambu 3D Printers Comparison: P1S vs A1 vs X1C

Is the Bambu P1S Worth the Upgrade Over the A1?

• For Basic Printing: Stick with the A1 if you’re only working with materials like PLA, PETG, or TPU. It’s the most cost-effective option without sacrificing performance.

How to 3D Print?

1. Download a design you want to print (the design file is called STL file) from sites such as thingiverse.
2. Import the design into a slicing application to prepare it for 3D printing.
   1. Customize the printing parameters based on the type of filament you are using.
   2. Export the instructions (G-Code) onto an SD card and insert it into the 3D printer.
3. Power on the printer, select the G-Code file, and press start.

Software Requirement

Slicing Software

Slicing software, or “slicer”, is essential for 3D printing; it takes your 3D design (in STL file format) and translates it into “G-Code.” Essentially, it “slices” the 3D model into layers and creates a toolpath for your 3D printer to follow.

This software also allows you to customize print settings such as layer height, print speed, and infill density. Cura is one of the most popular slicing software options, and it’s free.

3D Modelling Software

If you can find a design file online for the part you want to print, then you don’t need to create the design from scratch. However, if you want to create your own design, you will need 3D modeling software.

3D modeling software is used to design parts that can be 3D printed. There are many different software options available, ranging from beginner-friendly to professional-level programs. Popular options include Tinkercad, Fusion 360, and SolidWorks.

Beginners may find Tinkercad to be a good starting point for its ease of use and intuitive interface. More advanced users may prefer Fusion 360 and SolidWorks for their comprehensive feature sets and advanced tools. Fusion 360 offers a free version for non-commercial use, making it a great option to get started with.

Once a model has been created, it can be exported as an STL file, which can then be imported into slicing software to prepare it for 3D printing.

Filaments

There are several materials available for 3D printing drone parts. The most common ones are:

1. TPU (Thermoplastic Polyurethane) – A flexible and rubber-like material that is ideal for shock absorbers, motor mounts, and other components that require flexibility.
2. PLA (Polylactic Acid) – It is probably the most common filament used in 3D printing as it’s biodegradable, easy to print and has a low melting point, but it is brittle and has low impact resistance.
3. ABS (Acrylonitrile Butadiene Styrene) – A strong, durable, and heat-resistant plastic. It has a higher melting point than PLA, but it is more challenging to print due to warping and requires a heated bed.
4. PETG (Polyethylene Terephthalate Glycol) – A material that combines the strength and durability of ABS with the ease of printing of PLA. It has a high melting point and excellent layer adhesion.

Each material has its properties, advantages, and disadvantages. The choice of material depends on the specific application, design requirements, and personal preference. Personally, I use TPU and PETG 99% of the times, TPU for flexible parts and PETG for rigid parts.

How to Improve Printing Results

Have the printer and slicer settings dialled in makes a huge difference to the printing quality. Some key settings to adjust include layer height, infill density, and print speed. The ideal settings may vary depending on the complexity and size of the part, your printing environment and the material you use.

When printing with different materials, be sure to adjust the print temperature and bed temperature to match the recommended settings for that specific material. It is also important to properly level the bed to ensure a successful print.

Regular maintenance and calibration of your printer are also important for consistent and reliable printing.
