The Sculpfun iCube Ultra is a compact yet surprisingly capable laser engraving machine that has captured the attention of hobbyists, makers, and even mobile creators. Tested by Fat Air, this dual‑laser unit combines a 12W diode laser with a 1.2W infrared laser, offering flexible material support in a very small footprint.
In this review, we'll walk you through the design, features, performance, and real‑world applications, plus practical tips for outdoor use, initial setup, and materials testing.
🔎 1. Overview — What is the Sculpfun iCube Ultra?
The Sculpfun iCube Ultra is a dual‑laser engraving system packed into a 35 × 35 cm footprint—small enough to fit on a table yet powerful enough to tackle dozens of materials. One of the standout features is the interchangeable laser head system, allowing you to switch between:
- ✅ 12W Diode Laser — for engraving and cutting wood, acrylic, leather, and more
- ✅ 1.2W IR Laser (1064 nm) — ideal for metals like aluminum and stainless steel
Together, these two laser modules give you the flexibility to process 200–300+ materials, depending on your workflow and laser parameters.
✔ Home laser workshop | ✔ Mobile engraving at markets, weddings, events
✔ Small business production (custom gifts, signage) | ✔ Makers, DIY woodworkers, and creative entrepreneurs
🧰 2. Compact Design + Easy Setup
Despite its size, the iCube Ultra is thoughtfully engineered:
- Protective laser shield with magnetic safety switch
- Automatic focus via Z‑axis control
- X/Y axes standard for 150 × 135 mm work area (150 × 150 mm on diode‑only version)
- Removable laser head—swap IR and diode modules fast
The safety shield acts as a built‑in lens cover and ensures the laser pauses when opened or removed. Fat Air emphasizes always using eye protection even if safety shields are present.
🔧 Setup is straightforward with only a few screws to remove and plug. The Z‑axis automatically finds the optimal focus point using a side‑mounted button—great for beginners and pros alike.
💻 3. Software & Workflow (LightBurn Recommended)
Fat Air used LightBurn software throughout the review due to its reliability and ease of use:
- Set up your machine via USB‑C or Bluetooth (mobile support available)
- Home your axes and define workspace dimensions
- Position objects using absolute coordinates
- Use framing mode to preview job placement
- Upload SVGs, fonts, or graphics for precise engraving
LightBurn's automated focus and coordinate system makes repeatable engraving easier—especially when paired with dowel indexing points on the iCube Ultra bed.
☁️ 4. Portable Engraving — Outdoor + Event Ready
One of the most exciting parts of the review was using the iCube Ultra outdoors with a 230V portable power bank.
- ✔ Works efficiently with a 230V power station
- ✔ Drives laser and control electronics off grid
- ✔ Can be used with a laptop or phone
Fat Air demonstrated engraving right out on the grass using a power station like the Allpowers S300 Plus, making this a strong option for markets, birthday parties, and mobile engraving services.
📦 5. Material Tests — Real Results
🪵 Wood & Bamboo
Good engraving at moderate speeds. Bamboo's inconsistent density makes even engraving harder. Tip: Align engraving across grain and test regions.
🪨 Slate
Excellent contrast with diode laser. Lower power required for deeper, detailed engraving. Sand lightly if surface carbonizes too much.
🔲 Glass & Acrylic
Glass engraving works well despite low power. Best results when raising resolution and optimizing interval values. Lighted engravings look impressive.
🪓 Aluminum & Metal
IR laser can engrave aluminum business cards. Engraved QR codes scan reliably. Metals like stainless steel, titanium, and anodized aluminum all respond well.

📦 Other Materials: Paper, cardboard, ceramics, plastics. Leather engraving shows clean contrast. Adjust speed/power per material.
⚙️ 6. Performance & Speed
- 🔹 Up to 10,000 mm/min engraving speed
- 🔹 Laser spot size: 0.08mm / 0.03mm
- 🔹 Repeatability: 0.1 mm accuracy
These specs make it competitive even with larger hobby lasers. Fat Air notes it's not about maximum wattage but smart power use and good material testing—and the results reflect that.
👷 7. Safety + Ventilation
Dust, smoke, and exhaust are handled via:
- ✔ Built‑in smoke extraction outlet
- ✔ Optional exhaust hose attachment
- ✔ Removable charcoal + lamella filters
For indoor use, direct the exhaust outside. For outdoor use, filters are optional and can be removed entirely.
⭐ 8. Final Thoughts — Is It Worth It?
YES. The Sculpfun iCube Ultra is a standout in its size class.
It's practical, portable, beginner‑friendly, and capable of real commercial output.
Fat Air sums it up: pressure doesn't always come from power — precision, control, and workflow matter just as much.
✔ Pros
- ✓ True dual-laser (12W diode + 1.2W IR) — covers organics & metals
- ✓ Ultra-compact 35×35cm footprint, easy to transport
- ✓ Up to 10,000 mm/min engraving speed
- ✓ Interchangeable laser head system, swap in seconds
- ✓ Outdoor-ready with 230V power station
- ✓ LightBurn + Bluetooth + USB-C workflow
✖ Cons / Considerations
- Bamboo engraving requires extra tuning due to density
- 1.2W IR for marking (not deep metal cutting)
- Enclosure not included, smoke extraction add-ons optional
