Key takeaways
- AiForm-G1, FASTFORM’s liquid-cooling green laser metal 3D printer, prints 0.1 mm pure-copper fins with 0.07 mm spacing — half the industry-average fin thickness.
- Measured result: thermal efficiency up more than 30%, with system volume and weight both reduced.
- Metallographic testing after orthogonal-parameter tuning confirms ≥ 99.9% density; a 12 bar, 30-minute pressure-hold test performed live on the booth showed zero leakage (FASTFORM’s qualification testing is run at 20 bar / 30 min).
- Hardware: 500 W high-density green laser, ultra-small spot, and 0–200 °C dynamic substrate temperature control to eliminate cracking, deformation and melt-pool instability.
- OpenClaw (Lobster) AI runs an entire metal 3D printing job from one natural-language sentence — model repair, parameter matching, slicing, job dispatch, monitoring and MES integration — now available across FF-M420, FF-M300 and DeskFab X1.
On March 17, 2026, at TCT Asia, FASTFORM unveiled two headline innovations. The AiForm-G1 liquid-cooling green laser metal 3D printer took the lead in the liquid cooling race with its hard-spec combination of 0.1 mm precision and 99.9% pure-copper density. Alongside it, OpenClaw (Lobster) AI upended human–machine interaction by letting an operator start a metal 3D print with a single sentence. Together they pulled in overseas visitors, industry customers and trade media throughout the show.
01. Green Laser Firepower: 0.1 mm Fins, 0.07 mm Spacing, 30%+ Higher Cooling Efficiency
In pure-copper microchannel cold plate production, fin thickness and fin spacing directly determine cooling efficiency. Through continuous process optimization, the AiForm-G1 achieves:
- 0.1 mm fin thickness
- 0.07 mm fin spacing
- 30%+ higher thermal efficiency

At the TCT Asia booth, visitors examined real 0.1 mm fins directly under a high-resolution microscope — half the industry-average thickness, with spacing compressed by nearly 4×.
The breakthrough delivers more than 30% higher thermal efficiency while simultaneously reducing system volume and weight, meeting the core demand of high-end liquid cooling: efficient heat dissipation in a smaller, lighter package.
02. ≥ 99.9% Density, Zero Leakage: Microstructure and Performance Proven Live
Dimensional and efficiency gains are only the first step. What ultimately determines the value of a thermal component is performance — so FASTFORM’s TCT Asia booth ran a live demonstration that visitors could see, touch and measure.
Through orthogonal experiments systematically tuning filling process parameters, metallographic density reached ≥ 99.9%. Extreme-precision testing verified stable printing of 0.1 mm fins. And in the on-site performance validation, the parts passed a 12 bar, 30-minute pressure-hold test with no leakage — a booth-safe demonstration of the same sealing standard that FASTFORM validates in-house at 20 bar / 30 minutes, meeting the requirements of demanding sealing components and letting visitors experience “zero leakage” reliability firsthand.
The machine itself combines an ultra-small laser spot, a 500 W high-density green laser, and dynamic substrate temperature control from 0 to 200 °C. Together these eliminate the industry’s long-standing pure-copper printing problems — cracking, deformation and unstable melt pools — safeguarding long-term, stable operation of liquid cooling devices.

03. The World’s First “Lobster” AI Metal 3D Printer: One Sentence Starts the Full Print Workflow
Running in parallel with the green-laser copper breakthrough, FASTFORM OpenClaw (Lobster) AI sparked a second revolution on the TCT Asia 2026 show floor: one sentence, and an entire metal 3D printing workflow completes automatically.
At the demo screen, a FASTFORM staff member typed a natural-language instruction into the dialog box — “print this for me” — and the system responded instantly, automatically executing the full chain:
- Model inspection and automatic repair
- Intelligent matching of printing parameters
- Automatic slicing and toolpath planning
- Automatic job dispatch to the printer
- Real-time process monitoring
- MES production management integration
AI replaces a series of operations that previously depended on operator experience.
OpenClaw AI is now fully available across FASTFORM’s machine lineup:
- FF-M420 — an industrial mass-production metal 3D printer supporting 7×24 continuous production, built for industrial components, shoe molds and other batch manufacturing. With AI capability connected, mass-production management efficiency improves significantly.
- FF-M300 — part of the AI-enabled lineup.
- DeskFab X1 — a desktop metal 3D printer for professional fields such as dental labs. Its compact size and stable performance have earned broad market recognition; with OpenClaw AI onboard, the workflow is further simplified so professional users get productive faster.
04. FAQ: Green Laser Copper Printing and OpenClaw AI at TCT Asia 2026
What did FASTFORM present at TCT Asia 2026? Two innovations: the AiForm-G1 liquid-cooling green laser metal 3D printer, delivering 0.1 mm precision with 99.9% pure-copper density, and OpenClaw (Lobster) AI, which runs a complete metal 3D printing workflow from a single natural-language sentence.
How thin are the copper fins printed by the AiForm-G1? The AiForm-G1 prints 0.1 mm pure-copper fins with 0.07 mm spacing — about half the industry-average fin thickness, with spacing compressed by nearly 4×, for 30%+ higher thermal efficiency.
What density and leak performance do FASTFORM’s copper parts achieve? After orthogonal tuning of filling parameters, metallographic density reaches ≥ 99.9%. Qualification testing uses a 20 bar, 30-minute pressure-hold test with no leakage; at TCT Asia 2026 the same sealing standard was demonstrated live at 12 bar for booth safety.
What is OpenClaw (Lobster) AI? It is FASTFORM’s AI-driven metal 3D printing assistant. From one sentence it performs model inspection and repair, parameter matching, slicing and toolpath planning, job dispatch, real-time monitoring, and MES production management linkage — replacing workflows that previously relied on operator experience.
Which FASTFORM printers support OpenClaw AI? OpenClaw AI covers the full FASTFORM lineup, including FF-M420 (industrial mass production, 7×24 continuous), FF-M300, and DeskFab X1 (desktop, for dental and other professional applications).
From green-laser pure-copper hardware breakthroughs to OpenClaw AI interaction innovation, FASTFORM used visible technology, verifiable performance and immersive experience to deliver a concrete answer to the industry: build the foundation for mass production on hardcore fundamental technology, define equipment value by real user needs, and rebuild product experience around efficiency and practicality.
Going forward, FASTFORM will continue to deepen its work in AI liquid cooling and intelligent additive manufacturing, working with global customers to open up a hundred-billion-yuan blue ocean and share in the industry’s explosive growth.
