Bambu in the FCC Files: H3C, P3C, X2D Pro, AMS 3 and an S1 3D Scanner

The seven filings

Every FCC ID starts with a grantee codeThe first part of every FCC ID, assigned to one company. 2A6J8 is registered to Shenzhen Tuozhu Technology Co., Ltd., the company that also files Bambu's X2D, P2S, H2 and A-series printers.; Bambu's is 2A6J8. These are the entries added in September, with the product type exactly as each label prints it.

What the filings show

Everything in this section comes from the public part of each file: the grant, the test reports, the label drawings and the cover letters. We read the exhibit lists on the FCC's own database and the documents themselves on fccid.io, which mirrors the FCC record with readable copies.

Three printers: X2D Pro, H3C and P3C

All three labels read “3D Printer” and carry the Bambu Lab logo with the model name. Their frequency bands are identical: Wi-Fi at 2.4 GHz plus all four 5 GHz ranges (5.18 to 5.24, 5.26 to 5.32, 5.50 to 5.72 and 5.745 to 5.825 GHz). That is the same set the X2D's own filing covers. Bay Area Compliance Laboratories in Shenzhen tested all three, as it did the R1 and both AMS units.

The Wi-Fi modes are not identical. The H3C's test reports list 802.11ax (ax20 and ax40) at 2.4 and at 5 GHz, and the P3C's 5 GHz report lists the same; 802.11ax is the standard the Wi-Fi Alliance markets as Wi-Fi 6. The X2D Pro's reports list 802.11b/g/n at 2.4 GHz and 802.11a/n at 5 GHz, with no ax mode. These are the modes declared and tested for certification. They tell you which Wi-Fi standard the radio speaks, not what kind of machine is built around it.

The rated input printed on the labels is where they differ. The X2D Pro reads 100 to 120 V, 7 A, the same figure as the label of the X2D. The H3C and the P3C both read 100 to 120 V, 8 A, the figure on the H2C's label; the P2S label reads 5 A. On its own, a current rating does not tell you what a machine does with it.

The model numbers follow a pattern. The X2D Pro is PF004E, next to the X2D's PF004P and the P2S's PF004U. The P3C (PF006P) and the H3C (PF008P) got new numbers, while all four H2 machines filed so far share PF003 (H2D, H2S, H2C and H2D Pro). The H3C and P3C files each also contain a declaration that the printer can be built with one of three interchangeable 24 V power supply modules from different suppliers: 250 W modules for the H3C, 150 W for the P3C. The X2D Pro's file has no such declaration, but its test reports note two power supply modules, MOSO T40-TA042J240-250E0 and trelin DZTZ-250-24P. Both model numbers also appear in the H3C's declaration, rated 24 V, 250 W. The files do not say what those supplies power.

AMS 3H and AMS 3P

The labels spell the names out: “Automatic Material System 3H” (SA017) and “Automatic Material System 3P” (SA018). Each lists exactly one radio, a transmitter at 13.56 MHz, and no Wi-Fi or Bluetooth. That matches every AMS Bambu has filed before: the original AMS (2022), the AMS lite (2023), the AMS 2 Pro and the AMS HT (both 2025) are each listed at 13.56 MHz and nothing else.

The power inputs differ. The AMS 3H label reads 100 to 120 V AC, 200 W, or 24 V DC at 1 A. The AMS 3P label reads 24 V DC at 1 A only. For comparison, the AMS HT's label lists a mains input of 100 to 240 V, 1 A, and the AMS 2 Pro's label 24 V DC at 4 A.

Bambu Lab S1: a 3D scanner

The S1 (DS001) is the only new filing that is not a printer, an AMS or a laser, and its label is explicit: “3D Scanner / Escáner 3D”, input 20 V DC, 3 A, 60 W. Its SARSpecific absorption rate: how much radio energy the body absorbs, in watts per kilogram. The FCC sets different limits for the head and body and for the extremities. test report, written by SGS in Suzhou, classes it as a portable device, lists a 3.6 V, 4,800 mAh battery and describes the tested sample as a production unit.

Its radio setup is unusual for Bambu: Wi-Fi only, in two 5 GHz ranges (5.18 to 5.24 and 5.745 to 5.825 GHz). A signed declaration in the file says that the Bluetooth and 2.4 GHz Wi-Fi built into the device are disabled by software. The grant reports the highest SAR for “extremity exposure” at 3.81 W/kg; the FCC limit for hands, wrists, feet, ankles and outer ears is 4 W/kg. The printer and R1 grants work the other way round: they require at least 20 cm between the antennas and any person. The S1 was assessed for use against the hands or limbs.

R1: already launched

LM001P is the R1. The label reads “Laser Cutter” and “Class 1 Laser Product”, input 100 to 240 V, 5 A. The grant is dated September 21, 2026, and Bambu launched the R1 on its blog the next day; our R1 article has the specs and prices. It is the one entry in this batch that is not news.

What the filings do not show

No build volume, speed, nozzle count, chamber temperature, scan accuracy, price or date appears anywhere in the public part. Those details sit in documents Bambu asked the FCC to withhold: the user manuals, internal and external photos and test setup photos for 180 days, and the block diagrams, schematics and operational descriptions permanently. Still open:

• What the C in H3C and P3C stands for. The H2C is the model with Vortek, Bambu's induction hotend system (our H2C explainer); Bambu has not said what the letter stands for. Nothing in these files mentions hotends.
• What the X2D Pro adds. Ethernet, the obvious candidate for a Pro model, would not appear in an FCC radio filing at all.
• Whether the AMS 3H or 3P dries filament, and which printers they connect to. The labels show power inputs, not heaters.
• What the S1 scans, how accurately and with which software.
• Prices and release dates for any of the six.

Bambu itself has not mentioned any of them. Its blog, where it posted the launches of the H2D, H2D Pro, H2S, P2S, H2C, X2D, A2L and R1, has nothing on these six devices (checked October 7, 2026).

How to read an FCC filing

The confidentiality date is a limit, not a launch date

Bambu's cover letters ask for “short-term” confidentiality of the manuals and photos with a “secrecy cycle” of 180 days. That is why the release dates in the files land exactly 180 days after each grant: March 10, 2027 for the X2D Pro and the H3C, March 14 for the P3C, March 20 for the R1 and both AMS units, March 21 for the S1. The S1's letter adds that if the device is marketed within those 180 days, Bambu will notify the certification body, so the documents can also come out earlier.

“Composite device” means two radios, not a hidden feature

The X2D Pro, H3C, P3C and R1 files are flagged as a composite deviceFCC term for equipment that needs more than one equipment classification under the same FCC ID, with a separate application for each.. Here that simply means dual-band Wi-Fi: each file holds two grants, one for 2.4 GHz under Part 15C and one for 5 GHz under Part 15E. The X2D, P2S, H2D, H2C and H2D Pro filings carry the same flag. The S1 (5 GHz only) and the AMS units (13.56 MHz only) need a single classification and are not composite.

13.56 MHz points to the spool reader

Bambu's wiki describes how the AMS reads the RFID tags on Bambu spools with dedicated reader boards (see AMS detection issues for what goes wrong with them). The 13.56 MHz entry fits that reader, and it is the only radio listed in every AMS filing, old or new. Most likely it covers the same tag reading on the AMS 3H and 3P; beyond that, it says nothing about the new units.

Grant first, launch post soon after? Not reliably

For the eight machines Bambu launched since early 2025 we compared each FCC grant with the date of Bambu's launch post.

Three machines were announced shortly before their grant (the H2D by one day, the H2C by four, the H2S by six), and the P2S five weeks before. The H2D Pro followed six days after its grant. The 2026 launches were quick: the X2D two days, the A2L four days and the R1 one day after the grant. The six new devices have now gone 15 to 26 days without a post. That is longer than any gap after a grant in the chart, but it is not a countdown, and nothing in the files says how long it will last.

What it could mean (our reading)

X2D Pro. It shares the PF004 stem and the 7 A rating with the X2D, which points to a variant rather than a new machine. The E suffix has appeared twice before, on the X1E and on the H2D Pro, and Bambu launched the H2D Pro “for Enterprise Manufacturing”, with WPA2-Enterprise Wi-Fi and an Ethernet port. An X2D with the same business features is a plausible guess, nothing more.

H3C and P3C. The names read like the next generation of the H and P series, and both got new model numbers instead of the PF003 of the H2 family and the PF004 of the P2S. The H2C is the model with Vortek; Bambu has not said what the letter stands for. If the C marks the same feature on the new machines, Bambu would be bringing hotend swapping to the P series, but that is a guess on top of a guess, and the filings neither confirm nor rule it out. The P3C's 8 A rating, equal to the H2C's and above the P2S's 5 A, fits a more demanding machine but proves nothing on its own.

AMS 3H and 3P. H and P may simply match the printer series. The 3H's mains input mirrors the AMS HT, which Bambu describes as having a built-in heating and drying module; the 3P's 24 V, 1 A is a quarter of the current on the AMS 2 Pro's label. Whether either unit heats or dries is not in the files. If drying matters to you today, our filament dryer guide covers standalone dryers and when the AMS 2 Pro is enough.

S1. It is the clearest new category in the set: the label says 3D scanner, the test report says battery, portable and a production sample, and the radio was tested for exposure at the hands and limbs. What it scans, how accurately, with which software and at what price, the files do not say.

Common questions

What is the Bambu Lab S1?

A device Bambu Lab's manufacturer, Shenzhen Tuozhu Technology, certified with the FCC on September 22, 2026 under FCC ID 2A6J8-DS001. Its label reads “3D Scanner”, its SAR test report lists a 3.6 V, 4,800 mAh battery, and its only active radio is 5 GHz Wi-Fi. Bambu has not announced it, and the public filing contains no scanning specs, price or release date.

When will the Bambu H3C and P3C be released?

Unknown. The FCC granted the H3C on September 11 and the P3C on September 15, 2026, but the public files contain no release date. The March 2027 dates in the files are when the confidential manuals and photos become public at the latest, not launch dates.

What is the Bambu X2D Pro?

A printer certified under FCC ID 2A6J8-PF004E on September 11, 2026. Its label reads “3D Printer” with the same 100 to 120 V, 7 A rating as the X2D, and its model number shares the X2D's PF004 stem. What the Pro adds is not in the filing, and Bambu has not announced it.

Is the FCC confidentiality date a launch date?

No. Bambu asked for its manuals and photos to stay confidential for 180 days after each grant, so the dates simply fall 180 days later. The X2D shows the difference: Bambu announced it on April 14, 2026, and its FCC photos only became public on October 7, 2026.
