Three Print Heads

Boz stands in front of an H2C doing two nozzles and a Vortek rack, hears that a competitor went to nine, and announces that Bambu is doing three print heads. Not four — that would be playing it safe. Three, because “if one nozzle is good, and two is better, obviously three makes us the best fucking printer that ever existed.”

The all-hands

BOZ: Would somebody tell me how this happened? We were the goddamn vanguard of 3D printing. We put an AMS on every desk. We made bed slinger a slur. Then the other guys started shipping toolchangers. Were we scared? Hell no. We hit back with the H2C. Two nozzles. A Vortek rack. Six swappable hotends, and a dried spool for moisture. That was supposed to end the conversation.

BOZ: Then somebody in this building went to nine. Nine hotends in a rack. Ten nozzle positions. Published in August. Now we are standing here with our cocks in our hands, selling two nozzles and a desiccant puck. Moisture or no, suddenly we are the chumps.

BOZ: Well, fuck it. We are doing three print heads.

BOZ: Sure, we could go to four next, like the competition. Four is the next number after three. So let us play it safe. Put a slightly bigger screen on the H2C and call it the H2C Pro. Why innovate when we can follow? Oh, I know why. Because we are a business, that is why.

BOZ: You think it is crazy? It is crazy. But I do not give a shit. If one nozzle is good, and two is better, obviously three makes us the best fucking printer that ever existed. Comprende? We did not claw our way to the top of the extruder game by clinging to the dual nozzle standard. Three heads is the biggest swing of all.

BOZ: Here is the report from Engineering. Someone left it in the bathroom. I want to wipe my ass with it. They do not tell me what to invent, I tell them. And I am telling them to stick a third head on there. I do not care how. Swing it out on an arm. Bolt it to the back of the gantry. Cram it in perpendicular. Just do it.

BOZ: You are taking the multi in multi material too literally, grandma. Cut the strings and soar. Let us hit it. Let us roll. This is our chance to make printer history. Let us dream big. All you have to do is say that three heads can happen, and it will happen. If you are not on board, then fuck you. And if you are on the board, then fuck you and your father.

BOZ: People said we could not go to two. It will cost a fortune to manufacture, they said. Well, we did it. Now some egghead in a lab is screaming that three is crazy? Perhaps he would be more comfortable over at Prusa, working on fucking bed slingers. Cartesian, my white ass.

BOZ: The market? Listen, we make the market. All we have to do is put her out there with a little jingle. Printing with fewer than three heads is like painting a house with one bristle.

BOZ: I know what you are thinking now. Mew mew mew. Oh no, what will people say? Grow the fuck up. When you are on top, people talk. That is the price you pay for being on top. Which Bambu is, always has been, and forever shall be. Amen. Three heads, sweet Jesus in heaven.

BOZ: Stop. I just had a stroke of genius. Are you ready? Open your mouth, baby birds, cause Mama is about to drop you one sweet, fat nightcrawler. Put a camera on the third head, too. That is right. Three heads, two cameras, and make the second one actually useful. The second camera does calibration. It is a whole new way to think about printing. Do not question it. The patent office already published three of ours showing ten nozzles and a nine dock rack. That is not a leak. That is a warning shot. Just key the music, and call the chorus girls, because we are on the edge. The nozzle's edge. And I feel like dancing.

Editor's note: The H3C is a real FCC filing. On September 11, 2026, the FCC granted Shenzhen Tuozhu Technology Co., Ltd. — Bambu Lab’s legal entity — equipment authorization for an “H3C 3D Printer,” model PF008-P, FCC ID 2A6J8-PF008P, with dual-band Wi-Fi 6. Bambu asked to keep the external and internal photos, the user manual and the test-setup images confidential for up to 180 days, so the filing contains no product photos, no printing specifications, and no mention of a hotend rack, a toolchanger or a nozzle count; a second filing for an “X2D Pro” entered the database the same day (FCC record 2A6J8-PF008P; 3DPCC, Sep 2026). The nine-bay rack is real as a patent application: three Chinese applications assigned to Shenzhen Tuozhu, published August 14, 2026 — CN 122560409 A, CN 122560412 A and CN 122560413 A — describe a rack holding nine detachable hotends with a tenth working position on the shared toolhead. CN 122560413 A (priority date November 6, 2025) claims unlocking a hotend from the toolhead and seating it in the rack as a single motion; what detaches is the hotend — feed tube, heat break, heater and nozzle — while the extruder stays on the shared toolhead, a hotend changer in the same family as Bambu’s own Vortek and Bondtech’s INDX rather than a Prusa XL-style toolchanger. The applications name no machine, no date and no price, the claims are not limited to nine bays, and nothing in the public record connects the nine-bay design to the H3C (3DPCC patent analysis, Aug 2026). The shipping H2C pairs one fixed left nozzle with six swappable Vortek hotends — up to seven materials or colors per job, magnetic attachment, induction heating, a 350°C maximum nozzle temperature; it launched in November 2025 and the H2C Combo lists at $2,399 with one AMS 2 Pro (Bambu Lab H2C; PCMag, Feb 2026; Fabbaloo). “Nine toolheads on one rail” is a community reading of those patent drawings, not a filing or a spec; no nine-printhead Bambu machine has been confirmed, Bambu has issued no statement about the H3C, pricing is unknown, and community guesses for a reveal window range from the end of the 180-day confidentiality period to Formnext in Frankfurt, November 17–20, 2026 (3DPCC; Priceboon, Sep 2026).
