Bambu Lab Owns the C-End, So Why Is Lightweight Manufacturing Betting on Small B?

In the 3D printing space, Bambu Lab rose rapidly through the consumer market and became the industry's focal point. But not every player chooses to follow. Wang Zhiyu, founder of Lightweight Manufacturing—a serial entrepreneur who has worked at Sany Heavy Industry, Huawei, Creality, and Anker, and who led the AnkerMake M5 project—set out again in 2025, deliberately avoiding the crowded C-end red ocean and placing his chips on small B and manufacturing scenarios. His logic: the toy attribute of 3D printing has been validated, but the tool attribute is the bigger business.

From Anker M5 to Lightweight Manufacturing: A Hardware Veteran's Second Choice

Wang Zhiyu's résumé spans construction machinery, smartphones, and 3D printing. Around 2006, he worked at Sany Heavy Industry's Intelligent Research Institute on remote control for construction machinery, making him one of China's earliest engineers to touch IoT; he later moved to Huawei to work on Android phones, becoming one of the earliest Android developers. In 2019, he co-founded a startup with Huawei colleagues to build portable inkjet printers, selling more than 20 million yuan worth of product—an experience that later became important support for Anker's full-color 3D printing roadmap. After joining Anker in 2021, he completed the AnkerMake M5 in 12 months, with crowdfunding of $8.8 million—higher than Bambu Lab's project in the same period. The M5 generated about 60 million yuan in revenue in its first year, climbed to 120 million yuan in the second year, and approached 200 million yuan in the third.

These experiences left Wang Zhiyu with three things: the software, hardware, and supply chain expertise of a major phone company; accumulated inkjet printing technology; and a judgment about the C-end market. But precisely because of this, he understands the brutality of the pure consumer market—in his words, the pure consumer segment is "rolled into a tangled mess," with white-hot competition yet limited returns. In April 2025, Lightweight Manufacturing was founded with a clear direction: no ToC for now, with a primary focus on small B.

Small B and "Farms": An Overlooked Hundred-Billion-Yuan Manufacturing Market

Wang Zhiyu set his sights on a special group—3D printing "farms," namely merchants that provide printing services. These users typically own multiple machines and are highly sensitive to cost, efficiency, and waste, which is completely different from ordinary home consumers who care about "whether it's fun." He observed that in the 50 billion yuan 3D printing consumer market, printing "farms" account for nearly 20%, corresponding to about 10 billion yuan of space.

"Ordinary people's home printers are mostly just toys, and everyone focuses more on the toy attribute; we focus more on the tool attribute, on making the tool well so that printers can replace part of traditional manufacturing and solve real problems," Wang Zhiyu said. This judgment defines Lightweight Manufacturing's position: using the cost of ToC machines to accomplish what previously required industrial equipment costing 200,000 to 300,000 yuan.

However, pre-sale data also reveals a realistic side: individual users have a large base and make impulsive decisions, so they remain the main early buyers; small workshops are more cautious and will buy one unit to try first, but once it proves effective, their repurchase potential is stronger. Wang Zhiyu is not anxious about this. His strategy is to serve a portion of high-end users well first, then expand gradually.

A 3D printing farm (Print Farm) is an operating model that deploys multiple 3D printers in a centralized way for the purpose of batch production. Farm owners typically take customized orders from design studios, small and medium brands, or individuals, and dilute per-unit costs through economies of scale. Unlike home scenarios, farms are extremely sensitive to continuous operation stability, efficiency of multi-color and multi-material switching, and frequency of manual intervention, because any downtime directly translates into order delays and lost revenue. Currently, printing farms worldwide mostly use clusters of consumer-grade machines; the cost per unit is low, but management complexity is high, and one person can often only supervise a few machines. This is exactly the pain point Lightweight Manufacturing seeks to address: using more highly integrated equipment to lower the "human-to-machine ratio" and shift the farm's operating logic from "stacking machines" to "improving efficiency."

Four Printheads + Linear Motors: Dimensional Strike Using Industrial-Grade Components

Lightweight Manufacturing's core product is a four-printhead 3D printer. The figures Wang Zhiyu gives are quite aggressive: printing efficiency is 4 times faster than Bambu Lab, color switching is 5 times faster than Snapmaker U1, stability is "one or two orders of magnitude" higher, and precision is 100 times higher. Supporting these metrics is a technical solution completely different from mainstream consumer products.

Products from Bambu Lab, Snapmaker, and others generally use stepper motors plus belt drive, which keeps costs controllable but offers limited thrust. Lightweight Manufacturing instead chose industrial-grade linear motors—such motors were previously used mainly in the semiconductor field, with precision reaching the micron level. The crossbeam thrust brought by linear motors reaches 110N, several times that of conventional stepper motors, making it possible to install two printheads on one crossbeam, with four printheads working simultaneously without waiting to change heads.

"We have two crossbeams, with two heads on each crossbeam. Currently, very few companies put two heads on one crossbeam, because belt drive is unstable—one head already has weight, and two heads are even heavier, so the thrust of conventional stepper motors and the elasticity of belts are insufficient. Only with this kind of diamond drill do you dare take on this kind of porcelain work," Wang Zhiyu explained.

The direct benefit of this architecture is space and time efficiency: a four-printhead machine occupies only slightly more floor space than a single-head machine, yet can match four machines, saving 75% of space and time; material and labor costs are each cut by half, and management complexity drops sharply—one person used to manage four machines, now manages one. For printing farms, this is a real ROI improvement.

A linear motor (Linear Motor) is a drive device that converts electrical energy directly into linear motion without intermediate transmission mechanisms such as belts or lead screws. Its principle can be traced to maglev trains, using electromagnetic force between the stator and mover to achieve contactless thrust and high-precision positioning; it is commonly found in semiconductor lithography machines and high-precision CNC machine tools. Compared with stepper motor plus belt solutions, linear motors eliminate precision loss caused by belt elastic deformation and backlash, offer higher thrust density, and respond faster. However, their cost is significantly higher than consumer-grade drive solutions, and they place higher demands on heat dissipation and control algorithms. By introducing them into desktop-level 3D printing, Lightweight Manufacturing is essentially converting the cost-reduction dividend of industrial-grade motion control components into performance advantages within the consumer price band.

More Than Printers: The Ecosystem Ambition of Filament Machines and Automatic Part Removal Machines

Lightweight Manufacturing's product map does not stop at printers. Wang Zhiyu revealed that the team has also developed a desktop-level filament production device priced at more than $1,000, capable of producing 30 kilograms of filament per day. Its logic targets an industry pain point directly: most 3D printing filament today is made by shipping U.S. PLA pellets to China, drawing them into filament, and then selling them back to the U.S., with costs rising from $3/kg to $15/kg. Lightweight Manufacturing's solution lets users—especially U.S. farms or home users—buy pellets directly at $3/kg and produce filament at home at a cost of $6 to $7/kg, recouping the investment in about a week.

"Our gross margin will not decrease; it may even increase, but we will cut the user's selling price in half. This tool will overturn the entire logic of the filament industry," Wang Zhiyu said. He also stressed that this differs from Creality's waste recycling machine positioning: the latter focuses on crushing waste, mixing colors, and reusing it, while Lightweight Manufacturing is doing new-material production for heavy users who consume hundreds of spools per year.

Another accessory is an automatic model removal device, priced at several hundred dollars, solving the pain points of models sticking after printing and cuts when removing parts. "Everyone who has removed a model has bled, and I have too," Wang Zhiyu said with a laugh. Together, these peripheral products point to one goal: moving 3D printing from "can print" to "can produce."

The 3D printing filament supply chain has long suffered from a structural inefficiency: raw pellets of materials such as PLA are mainly produced in the U.S., shipped to China to be drawn into filament, and then exported to European and American markets. Logistics and processing inflate the terminal price from a pellet cost of about $3/kg to a filament selling price of $15/kg. The emergence of desktop-level filament production equipment (Filament Extruder) attempts to compress this chain, allowing heavy users to use pellets directly as raw material and complete drawing locally. The technical difficulty of such equipment lies in wire diameter consistency control and cooling processes; early products often caused printing failures due to insufficient precision. If desktop filament extruders can stably output qualified filament, they will fundamentally change the pricing logic of filament and the geographic distribution of the supply chain.

Manufacturing Outsourced to Sunwoda: The Confidence of Capacity and Delivery

Lightweight Manufacturing has handed its manufacturing to Sunwoda. The latter specifically freed up an entire building for it, with daily capacity reaching 400 units. As of July, the company had shipped 50 devices and had 200 units ramping up on the production line, with a new round of shipments to begin in November. Behind this capacity layout is the "advanced cultivation" logic of Sunwoda's 3C business unit—they previously invested in and deeply participated in the manufacturing iteration of pool robot company Yuanding in a similar way, helping it grow into the leader in its niche track.

On the channel side, Lightweight Manufacturing's Kickstarter crowdfunding exceeded $3 million, ranking tenth in 3D printing crowdfunding history (excluding UV and resin projects), with another $3 million in offline orders, including from a European company. Wang Zhiyu's attitude toward crowdfunding is pragmatic: "Advertising costs are very high, and crowdfunding is not the only path. We want to deliver in small batches, see the results first, then iterate, then deliver."

Bambu Lab and Lightweight Manufacturing: A Displaced Competition Like HP and Ricoh

To outsiders, a battle between Lightweight Manufacturing and Bambu Lab seems inevitable. But Wang Zhiyu uses the history of the printer industry as an analogy: HP's home printers are cheap and highly popular, while Ricoh focuses on commercial copiers and printing equipment; the two have completely different scenarios, batch requirements, and user demands, and do not constitute direct substitution. "Bambu Lab is expanding the circle and serving novice users, which is a good thing—the whole world knows 3D printers are fun. But when it comes to real batch manufacturing, the logic is completely different."

He further explained that entertainment consumption is interest-driven, while print shops and farms want to make money; whether it is fun is not important. Selling a machine with 256 printheads to households is unrealistic, but for a factory, one machine may replace work that previously required a large factory building. Lightweight Manufacturing's roadmap confirms this: four printheads are only the starting point; the next generation has 16 printheads, the one after that 64, ultimately pointing to 256 printheads, while the machine size can remain unchanged—only the printhead size continues to shrink.

In AI and 3D generation, Wang Zhiyu remains restrained. In the short term, the company will not develop foundation models in-house but will choose external partnerships to leverage existing AI capabilities. He prefers the path of "AI-assisted designers"—shortening work that originally took engineers and designers a day to half an hour, rather than pursuing fully foolproof "one-sentence model generation." This is consistent with Lightweight Manufacturing's user profile: senior people such as engineers and designers with strong design capabilities, who need efficiency and tools rather than replacement.

The Ultimate Imagination for Lightweight Manufacturing

The name "Lightweight Manufacturing" itself carries Wang Zhiyu's judgment about the endgame. He positions the company as "a complete lightweight manufacturing solution," not limited to 3D printing alone, but turning big equipment and big manufacturing into small manufacturing, bringing manufacturing back to the place of origin and back to users' side—in Europe, in the United States, in small towns, where users can make things themselves without relying on giant factories far across the Pacific.

"We are the people handing shovels to the manufacturing of the future," Wang Zhiyu said. While Bambu Lab rolls toward the C-end mass market, Lightweight Manufacturing has chosen a narrower but potentially deeper path: serving those who make money with 3D printing. The scale ceiling of this path remains to be verified, but it at least offers a different possibility—the next stage of 3D printing may not necessarily be flashier toys, but could also be handier production tools.

One-line Summary

Lightweight Manufacturing avoids the crowded C-end red ocean and targets the 3D printing farm and small-B manufacturing market with an industrial-grade four-printhead printer.

Paragraph Summary

Founded in April 2025, Lightweight Manufacturing was started by Wang Zhiyu, who previously led the AnkerMake M5 project and has a hardware résumé spanning construction machinery, smartphones, and 3D printing. The company has temporarily abandoned ToC and focuses on small-B users such as 3D printing "farms," targeting a printing services market of about 10 billion yuan. Its core product, a four-printhead printer, uses industrial-grade linear motors with crossbeam thrust of 110N, claims efficiency 4 times that of Bambu Lab and color switching 5 times faster than Snapmaker U1, and has raised more than $3 million on Kickstarter. The company has also launched a desktop filament production machine and automatic part removal accessories, attempting to extend from equipment vendor to filament ecosystem. Manufacturing is outsourced to Sunwoda, with daily capacity of 400 units. Wang Zhiyu compares Bambu Lab and Lightweight Manufacturing to HP and Ricoh, arguing that consumer-grade and manufacturing-grade scenarios have different demands, so displaced competition outweighs direct conflict.
