Introduction
Building a metal laser cutting machine used to be a complex and resource-heavy project, often limited to large factories with sufficient space, budget, and technical support. Traditional systems required not only a laser source and motion platform, but also additional infrastructure such as water chillers, piping, and ongoing maintenance planning.
Today, this situation is gradually changing. With the development of air-cooled fiber laser technology, a more practical and accessible approach has emerged. Instead of focusing on large industrial setups, more users are now building compact, efficient laser cutting systems that are easier to install, operate, and maintain.
For small workshops, startups, and even individual builders, this opens up a much more realistic path into metal laser cutting.
Why Air-Cooled Laser Systems Are Becoming the Preferred Choice
One of the most significant differences between traditional and newer solutions lies in the cooling method. Water-cooled systems, while effective, introduce additional complexity that affects nearly every part of the machine—from layout planning to long-term maintenance.
Air-cooled solutions simplify this structure by removing the need for an external chiller. This change directly reduces the overall footprint of the machine and makes installation much more straightforward. At the same time, fewer components mean fewer potential points of failure, which improves long-term reliability.
For users working with limited space or tighter budgets, this simplicity often makes a greater difference than pushing for maximum cutting power. It allows them to focus on building a system that is practical, manageable, and scalable over time.
Core Components (Recommended Products)
Even in a simplified DIY setup, the performance of the machine depends heavily on how the core components are selected and matched. For compact metal cutting applications, mid-range configurations are typically the most practical starting point, offering a balance between cost and usability.
To make the selection process clearer, here is a recommended combination based on real-world applications:
Laser Source (Fiber)
- 800W Fiber Laser (RFL-C800A1, JFSC-800M)
- 1200W Fiber Laser ( RFL-C1200A1, JFSC-1200M)
Please refer to the left image for RFL-800A1 and RFL-C1200A1, and the right image for JFSC-800M and JFSC-1200M.
These power ranges are well-suited for small-format machines and are easier to integrate into compact setups.
If it's a blue light + fiber optic hybrid solution, the corresponding laser configuration needs further clarification, for example:
- Blue Light Laser: S70
- Fiber Laser: RFL-C800A1, JFSC-800M, RFL-C1200A1, JFSC-1200M
Air-Cooled Cutting Head
Manual Air-cooled Cutting Head
- A50M (manual focus, lightweight, budget-friendly)
The image on the left of the above pictures shows a model of the A50M, while the image on the right shows a real photograph of the A50M.
Auto-focusing Air-cooled Cutting Head
- A130E (auto-focus, more stable and user-friendly；this cutting head is currently used in SF-CutAir, offering a more complete overall experience and making it more convenient to use.)
The choice here depends on whether you prioritize initial cost or long-term usability.
Air-Cooled Cutting System
Pure Fiber Optic Air-Cooled Cutting System
Recommended Model: MCC200 (for cutting small-format metal sheets using pure fiber optics)
Blue Light + Fiber Optic Composite Control System
Recommended Model: MCC200-MIX (Currently, CutAir uses a combination of blue light and fiber lasers, but for DIY solutions, the specific system model, switching logic, and adaptation method still need to be confirmed during the final selection).
The three images above illustrate the MCC100-MIX control system and its related cables. These images can be used as a reference for the MCC200 and MCC200-MIX.
Chiller
For traditional fiber laser cutting equipment, a water-cooled system is usually standard.
However, one of the advantages of the air-cooled approach discussed in this article is that it eliminates the need for a separate water-cooled system.
This gives the entire system a significant advantage in terms of size, installation, and maintenance.
Two Practical DIY Approaches
In real applications, most users don’t start completely from scratch. Instead, they tend to follow a clearer and more structured path based on their goals, budget, and technical experience.
At the moment, there are two practical directions that have proven to be both achievable and scalable in real-world DIY projects.
Solution 1: Pure Fiber Air-Cooled System (Entry-level)
This is the most straightforward and widely adopted approach, especially for users building a compact metal laser cutter for the first time. By combining a fiber laser source with an air-cooled cutting head and a dedicated control system, the overall structure remains simple while still delivering reliable cutting performance.
Because it avoids unnecessary complexity, this solution is easier to assemble, more cost-effective, and better suited for small-format applications such as workshops, prototyping, and light production.
Recommended configuration:
Fiber Laser Source:
- 800W ( RFL-C800A1, JFSC-800M): Entry-level, budget-friendly
- 1200W (RFL-C1200A1, JFSC-1200M): More stable, better performance
Air-Cooled Cutting Head:
Control System:
- MCC200 (standard air-cooled fiber cutting system)
This combination provides a solid balance between simplicity, cost, and usability, making it the preferred starting point for most users.
Solution 2: Blue Laser + Fiber Hybrid System (Standard-level)
For users looking for more flexibility in material processing, a hybrid solution that combines a fiber laser with a blue laser offers additional possibilities. This setup allows the system to handle a wider range of materials, but it also introduces more complexity in terms of control logic and integration.
Because of this, it is generally better suited for users who already have some experience with machine building or access to technical support.
Recommended configuration:
Fiber Laser Source:
- 800W fiber laser: RFL-C800A1, JFSC-800M
- 1200W fiber laser: RFL-C1200A1, JFSC-1200M
Blue Laser Source:
- S70 (for hybrid applications)
Control System:
- MCC200-MIX (supports fiber + blue laser integration)
Compared to the pure fiber solution, this approach focuses more on expandability rather than simplicity. It is a good option for users planning to develop more advanced or customized applications over time.

Composite Functionality and Future Expansion
Then a Blu-ray + fiber optic composite solution is worth considering.
However, it is recommended to clarify the following points before making a selection for this type of solution:
- Specific model of the composite system: MCC200-MIX
- Switching method between blue light and fiber optic: Internal software switching
- Optical path and control logic: Fiber laser uses 24V PWM, blue light uses 5V PWM control
- Compatibility with corresponding platforms and architectures
Key Supporting Systems
While the core components define what the machine can do, the supporting systems determine whether it can run smoothly, consistently, and long-term in real working conditions. In many DIY projects, this is often the part that gets underestimated—but in reality, it has a direct impact on stability, cutting quality, and maintenance frequency.
To avoid unnecessary complexity, it is usually more practical to choose pre-matched and proven configurations rather than assembling everything from scratch.
Gas Control System
For metal cutting, the gas system is not optional—it directly affects cutting quality and efficiency. Instead of selecting individual valves, regulators, and filters one by one, using a complete gas control module can significantly simplify the setup process and reduce potential compatibility issues.
Recommended options:
- NNT dual gas control module (integrated solution)
- SMC dual gas control module (more stable, industrial-grade option)
These solutions allow users to work with a ready-to-use configuration, avoiding trial-and-error during installation.
Motion System (X / Y / Z Axis)
The motion system defines how accurately and smoothly the machine can operate. Even with a good laser source, poor motion control will directly affect cutting precision and consistency.
A properly matched servo system ensures stable movement and better performance during continuous operation.
Recommended configuration:
Leadshine Servo Motors:
Leadshine Servo Drivers:
- L6P series drivers (matched with servo motors)
The above are pictures of the Leadshine L6 series drive, motor, and cables.
This combination provides a reliable balance between performance and compatibility for small-format DIY machines.
Electrical System
The electrical system connects all components into a complete working machine. A well-designed setup not only ensures stable operation but also improves safety and ease of maintenance.
Instead of piecing together random components, using standardized and widely tested electrical parts can greatly reduce troubleshooting time later.
Recommended components:
- Main switch: Schneider isolator
- Contactor: Schneider LC1D series
- Relay: 24V DC relay modules
- Power supply: 24V industrial power supply (e.g., 600W level)
- Emergency stop & safety circuit components
A structured electrical setup makes the system easier to debug, safer to operate, and more reliable in long-term use.
Consumables and Structural Considerations
Beyond the main system, there are several practical details that can greatly influence how usable and sustainable a DIY laser cutter really is. These are often overlooked during the initial build, but they quickly become critical once the machine starts running regularly.
Consumables
Recommended consumables:
- Nozzle: D28M11
- Protective lens: D20 × 3
- Ceramic holder: D28M11
- Sensor cable: TTW (15 cm)
- Spare parts (suggested):
