The SLC micro SD card from ATP Electronics is listed as an industrial-grade, 4 GB removable storage card for compatible devices. It provides a dedicated place to store and transfer files, including print files used with supported 3D printers. The product listing identifies the flash type as SLC and the speed class as Class 10.

For a 3D printing workflow, the card can hold compatible files transferred from a computer for use on the printer. A dedicated card keeps those files together and can be removed when needed. The product listing identifies Bambu Lab A1 and P1S as compatible models. Check the requirements of your exact device before ordering, rather than assuming that every printer or other device supports the card.

With 4 GB of storage, this card is a compact choice when the main purpose is keeping print files on hand. Users who save many videos or time-lapse recordings may prefer a higher-capacity compatible card. Bambu Lab specifies FAT32 for its printers; check the card’s current format and back up any files before formatting. Use the printer’s eject option before removing a card from an A1 or P1 series printer. This is an ATP card, not an official Bambu Lab accessory.

ATP Micro SD Card Overview

A compact SLC option for smaller storage workloads

For users whose compatible equipment needs modest storage and who prioritize SLC flash, this 4 GB ATP card offers an alternative to larger general-purpose microSD cards. A higher-capacity card is more practical for large operating system images, recordings, or applications that need room to grow. Capacity alone does not establish endurance, so compare the documented specifications of each card and check the host device’s requirements.

Requirements & Installation Notes

  • Check the host device’s microSD card type, supported capacity and file-system requirements before ordering.
  • 4 GB is below the current recommended minimum for Raspberry Pi OS; check the requirements of your chosen software.

Frequently Asked Questions About ATP Micro SD Card

How often should I format this industrial SD card for my Bambu Lab/Ender 3 printer?

Following the key 3D printing habit of regular（4-6 weeks） formatting (FAT32) is still recommended to keep the card running optimally, and this industrial SLC SD card is built to withstand frequent formatting without wear or performance loss—unlike consumer cards that degrade quickly with repeated formatting.

Will this SD card work with the FAT32 file system required by Bambu Lab printers?

Yes. This industrial SD card is pre-optimized for the FAT32 file system (the only format supported by Bambu Lab and most FDM 3D printers like Ender 3).

Is 4 GB enough for my device?

It depends on the files, recordings, and software you plan to store. Four gigabytes can suit modest storage workloads, but larger operating system images and video recordings may require more capacity. Check your device and software requirements before ordering.

Can I use this card with a Raspberry Pi or desktop CNC controller?

The card may be considered for projects or controllers that support its microSD format, capacity, and required file system; compatibility has not been verified for every device. Current Raspberry Pi OS recommendations start at 8 GB for Lite and 32 GB for the desktop editions, so this 4 GB card is below those recommendations.

Support FAQ 

What Should I Buy from Call3D?

Call3D is particularly valuable when you are looking for:

  • Carefully selected third-party accessories, mods, and upgrades for Bambu Lab printers;
  • Compatibility-sensitive parts that require clearer model, version, or installation guidance;
  • Specialized solutions that may be difficult to identify on general marketplaces;
  • Newly released or locally unavailable Bambu Lab products;
  • Multiple accessories that can be combined into one order.

Every product we list is selected for a clear functional purpose, with compatibility, installation requirements, and known limitations reviewed before publication. Our goal is to help customers choose the right solution—not simply offer the largest possible catalog.

Why Call3D over a Marketplace?

General marketplaces may offer a large number of similar-looking products from different sellers, making it difficult to evaluate compatibility, product quality, and after-sales responsibility.

Call3D operates as a specialist curated store. We review a product’s purpose, compatibility, installation requirements, and available technical information before listing it. If customers need help before ordering or encounter a problem afterward, they can contact the same team that selected and documented the product.

We focus on long-term customer relationships, clear communication, and responsible after-sales support rather than a one-time transaction.

  •  Found this shop on Reddit, chatted with a real person about the P2S filter I needed. Asked if they could ship to SG, they checked and made it happen! Super happy because this filter is basically impossible to find locally and always out of stock everywhere else. Fast, friendly, and solved my problem perfectly. Will buy again!

  •  When EP invited me to Shenzhen back in 2019, I was absolutely blown away by the hardware innovation coming out of China. Just one year later, Bambu Lab burst onto the scene—and their solutions have grown right alongside Bambu, evolving from the very beginning to where they are today.

  •  Bought a ventilation system but changed my mind last minute. I thought returns would be a huge hassle, but they told me there’s a return warehouse in Houston only about a 10-minute drive from where I live in Missouri City. Drove over and returned it super easily. Super convenient return process, great experience overall!

Great SLC card, but a heads-up: remember to turn off the surveillance recording function. Otherwise, even if you don’t have time-lapse photography enabled, the device will keep recording as long as it’s on. In as little as 3 months or up to a year, the original card will definitely fail.

It seems the a1 doesn't have RAM; instead, it directly uses the SD card as RAM, leading to frequent read/write operations, which is why the SD card was prone to failure. So I replaced it with an SLC card, and it's been running for half a month now—probably will last a long time.
