IR: 2W · 1064nm Diode: 10W · 455nm Speed: 5,000mm/s Accuracy: 0.0001mm Safety: Class I Enclosed Materials: 300+

Quick Verdict

The Sculpfun G9 is the most accessible Class I enclosed dual-laser galvo engraver available — delivering professional-grade speed and precision without the safety barriers, complexity, or price tag of open-frame alternatives.

Where most dual-laser machines at this price make you choose between portability and safety, the G9 refuses the compromise. The fully enclosed Class I housing means no goggles required during normal operation, the lid-open auto-stop prevents accidental exposure, and the built-in exhaust fan manages fumes — all without sacrificing the industrial galvo core that gives it a 5,000mm/s maximum speed and a 0.0001mm repeat positioning accuracy that rivals machines costing three times as much.

The 2W 1064nm infrared laser handles metals, plastics, and ceramics without marking spray. The 10W 455nm blue diode cuts 10mm wood and 6mm black acrylic. Together they cover 300+ materials — and the optional slide extension kit expands the 105×105mm work area to 3.5× its original size, making batch production genuinely practical from a machine you can carry to a craft fair.

Sculpfun G9 dual laser engraver — compact enclosed Class I machine with 10W diode and 2W infrared galvo laser

Galvo Speed. Enclosed Safety. Dual-Laser Versatility.

The Sculpfun G9 is Sculpfun's first enclosed galvo laser engraver — built around three ideas that rarely coexist at this price point: industrial-grade speed from a galvo mirror system, Class I safety from a fully enclosed housing, and a dual-laser configuration that covers metals, plastics, wood, acrylic, and 300+ other materials without spray or coating.

At 6.4kg and 230×195×321mm, the G9 is compact enough to pack for a craft show and capable enough to run batch production jobs. The electric lift focusing system eliminates manual adjustment entirely — align the red and blue preview dots, and the machine sets its own focus depth. No calipers, no guesswork.

What Is the Sculpfun G9?

The G9 is Sculpfun's answer to a specific maker problem: you need to engrave metals and plastics with infrared precision, cut wood and acrylic with a diode, do both inside a safety-compliant machine that doesn't require goggles during normal operation, and carry the whole setup to a market stall on weekends. Until recently, no single machine under $1,000 could satisfy all four requirements at once.

The G9 uses a galvanometer (galvo) scanning system instead of the gantry-and-carriage movement used by most desktop laser engravers. In a galvo machine, fixed mirrors deflect the laser beam at high speed across the work area — there are no moving carriages, no belt tension, no V-slot backlash. This is how the G9 achieves 5,000mm/s engraving speed while maintaining 0.0001mm repeated positioning accuracy and a 0.01mm beam spot. The K9 optical-grade glass reflectors minimize energy loss at each mirror, preserving beam quality at the work surface.

The enclosure is not cosmetic — it's the certification. The G9 meets Class I laser safety standards, the same classification as consumer electronics. The lid-open auto-stop is hardware-level. The built-in exhaust fan manages smoke during operation, and the optional air purifier connects for near-complete indoor fume filtration.

💡 Class 4: Most open-frame diode engravers are Class 3B or Class 4 — which legally require eye protection and controlled operating environments.

Sculpfun G9 dual laser sources — 2W 1064nm infrared and 10W 455nm diode blue laser for metal and wood engraving

Two Lasers, One Machine — No Compromise on Either

The G9's dual-laser setup reflects a genuine material science reality. The 2W 1064nm infrared laser interacts with metals and plastics at the molecular level — creating permanent marks without ablation or burning. The 10W 455nm blue diode absorbs strongly in organic materials, enabling the thermal cutting and surface engraving that metals reflect entirely.

Switching between lasers is handled in SGD Laser or LightBurn — no physical module swap. Select the laser type in software, set your parameters, and the galvo system uses the appropriate source. Mixed-material workflows — engraving a metal tag and cutting a wood backing in the same session — are genuinely fluid.

Why the Galvo System Changes Everything

Most desktop laser engravers move a laser head on X and Y rails using belts or lead screws. Physical movement caps maximum speed — the acceleration and deceleration of a carriage creates mechanical limits that no amount of motor tuning can fully overcome. Above ~600–800mm/s on gantry machines, quality begins to degrade.

A galvanometer system deflects the laser beam using two precision mirrors driven by galvo motors. There's no heavy carriage to accelerate — only a beam of light redirected by mirrors weighing grams. This is why the G9 achieves 5,000mm/s engraving speed and 10,000mm/s preview speed while maintaining 0.0001mm repeated positioning accuracy. The K9 optical-grade glass reflectors minimize energy loss at each reflection, preserving beam quality at the work surface.

5,000mm/s (IR) · 4,000mm/s (Diode)

Galvo speed is 8–10× faster than gantry machines. Complex vector designs that take minutes on a carriage machine complete in seconds on the G9.

SGD Laser + LightBurn: Free and Pro, Side by Side

The G9 ships with the free SGD Laser app, available on Android, iOS, Windows, and macOS. SGD Laser handles the complete workflow — import SVG, JPG, PNG, or DXF files, set engraving layers, select laser type, preview the job, and run it via Wi-Fi. Material presets recommend starting parameters for common materials, significantly reducing trial-and-error for new users.

LightBurn compatibility extends the G9's appeal to users who already have established workflow files. The Wi-Fi connection works with both applications — no USB cable required once on your network, making it practical for stand-alone operation on a workbench, at a market stall, or in a classroom with no PC nearby.

Real-World Output Across Materials

The G9's 0.01mm beam spot and galvo precision show clearly in finished work. Metal dog tags display fine serif fonts and logo details that blur on gantry machines running at comparable speed. Wood cuts have clean edges with minimal charring from the focused 10W diode. Leather engraving maintains consistent depth across fills without speed artifacts.

Business card blanks, custom jewelry, personalized gifts, product labels, and signage pieces all fall within the G9's core capabilities — and the slide extension kit makes batch work on these items significantly more practical than repositioning items under a 105×105mm field one by one.

How Does the G9 Compare?

The G9 competes directly with the xTool F1 — the most established enclosed galvo dual-laser machine at a similar power level — and the xTool F2 and WeCreat Lumos as higher-power portable alternatives:

The G9 and xTool F1 are the most direct comparison — same laser power class, same Class I safety, similar work area. The G9 leads on IR engraving speed (5,000 vs 4,000mm/s) and repeat positioning accuracy (0.0001mm vs ±0.01mm). The xTool F2 and WeCreat Lumos step up to 15W diode and more cutting depth, but at a meaningfully higher price. For users who need the G9's specific combination of 2W IR precision, Class I safety, galvo speed, and slide-kit batch capability — without paying the xTool F2 premium — the G9 occupies a compelling, largely uncontested position.

Built for How Real Makers Actually Work

The G9's design philosophy starts with the user. Makers who take it to markets don't want to wrestle with focus discs or remember to put goggles on. Jewelers working in a shared studio don't want to explain to co-workers why there's a Class 4 laser on the bench. Teachers don't want a machine that requires a separate safety protocol briefing each session.

The G9 addresses each friction point: auto-focus, Class I housing, built-in exhaust, free cross-platform app, and a form factor that fits in a carry bag. The result is a machine that gets used consistently — not one that stays on a shelf between projects because setup is too involved.

Frequently Asked Questions

What is the difference between the Sculpfun G9 and a regular diode laser engraver?
A regular diode laser engraver uses a moving carriage to physically move the laser head on X and Y rails. The G9 uses a galvanometer system: two precision mirrors deflect the laser beam at high speed — no heavy carriage to accelerate. This is why the G9 reaches 5,000mm/s while open-frame machines typically top out at 400–600mm/s before quality degrades. The G9 also has two lasers (2W IR + 10W diode), is fully enclosed with Class I safety certification, and includes electric auto-focus. Regular diode engravers are typically open-frame, single-laser, and require safety goggles during use.
Can the G9 engrave bare metal without marking spray?
Yes — this is one of the G9's primary advantages. The 2W 1064nm infrared laser interacts directly with metals at the molecular level, creating permanent marks on stainless steel, aluminum, brass, copper, gold, silver, titanium, and platinum without any marking spray or chemical coating. The 10W 455nm diode laser does require marking compound on bare metals — but the diode is primarily intended for wood, acrylic, leather, and other organic materials where it performs natively without any additives.
How does the G9 compare to the xTool F1?
Both machines share the same fundamental configuration: 2W 1064nm IR + 10W 455nm diode, galvo scanning, Class I enclosed housing, and portable form factor. The G9 leads on IR engraving speed (5,000mm/s vs xTool F1's 4,000mm/s) and repeat positioning accuracy (0.0001mm vs ±0.01mm). The xTool F1 has a marginally larger work area (110×110mm vs 105×105mm) and the benefit of xTool's larger software ecosystem and community. The G9 offers LightBurn compatibility and the free SGD Laser app across all platforms. Both support slide extension kits.
How does the electric auto-focus work?
The G9 uses an electric lift to adjust the machine's height relative to the workpiece. Two preview beams — a red dot and a blue dot — are projected onto the work surface. When the two dots overlap into a single point, the machine is at the correct focal distance. Raise or lower using the electric lift until the dots merge, then lock. No focus discs, no calipers. Changing from a 3mm dog tag to a 10mm wood plank takes seconds — adjust the lift until the dots merge again and you're focused.
What is the G9 Slide Extension Kit and how much does it expand the work area?
The G9 Slide Extension Kit is an optional accessory that allows the workpiece (or a tray) to slide linearly beneath the engraving head, expanding the processable area up to 3.5× the base 105×105mm field. It makes the G9 practical for batch production — engraving multiple items in sequence without repositioning — and for longer workpieces like keychains in a row or multi-panel signs. The RA Pro Max rotary is a separate accessory for cylindrical work such as mugs, glasses, rings, and pens.
Does the G9 need ventilation?
The G9 has a built-in exhaust fan and an exhaust duct port. Connect the included duct and route fumes to a window or external vent. For metal and plastic engraving, fume output is minimal. For wood and acrylic cutting, proper ventilation is important. Sculpfun offers a compatible air purifier (sold separately) that connects to the exhaust port and filters fumes to approximately 99.97% efficiency — enabling clean indoor operation without window access, recommended for school and office environments.
Is LightBurn fully compatible with the Sculpfun G9?
Yes — the G9 is compatible with LightBurn on Windows and macOS. Note that galvo machines like the G9 require a LightBurn Pro (galvo) licence, which is separate from the standard LightBurn gantry licence. If you already have a standard LightBurn licence from a gantry laser, you'll need to verify compatibility or upgrade before using it with the G9. The free SGD Laser app covers the full feature set for most users across Android, iOS, Windows, and macOS — it's the recommended starting point for new G9 users, with LightBurn as the professional workflow alternative.
