Enclosed vs Open-Type Fiber Laser Cutting Machine: Key Differences

When choosing a fiber laser cutting machine, one of the most important decisions manufacturers face is whether to select a fully enclosed model or an open-type machine. While both are widely used in metal fabrication, they serve different production needs, safety requirements, and budget considerations.

This article explains the key differences between enclosed and open-type fiber laser cutting machines, helping you make the right choice for your factory.

This article explains the key differences between enclosed and open-type fiber laser cutting machines, helping you make the right choice for your factory.

【Design Structure and Safety】

Fully Enclosed Fiber Laser Cutting Machine

A fully enclosed machine features a protective metal housing with laser safety viewing windows, completely isolating the cutting area from the external environment.

Key safety advantages:

Prevents laser radiation exposure

Protects operators from sparks and flying debris

Reduces risk in high-power laser applications

Meets stricter international safety standards (CE, FDA, etc.)

This design is especially important for high-power fiber lasers and factories with multiple operators working nearby.

Open-Type Fiber Laser Cutting Machine

An open-type machine has an exposed cutting table without full protective enclosure.

Characteristics:

Operators can directly observe the cutting process

Requires additional safety training and protective measures

More suitable for lower power configurations or controlled environments

Summary:

Enclosed machines offer significantly higher safety levels, especially for modern industrial workshops.

【Laser Power Compatibility】

Enclosed Type

Fully enclosed fiber laser cutting machines are typically designed for medium to high power ranges, such as:

6kW, 12kW, 20kW, up to 30kW and above

The enclosure helps:

Contain strong laser reflections

Manage heat and sparks

Support stable long-term operation for thick plate cutting

Open Type

Open-type machines are more commonly used with:

Low to medium power fiber lasers (e.g. 1kW–6kW)

At higher power levels, open designs increase safety risks and are less favored in regulated markets.

【Cutting Environment and Workshop Cleanliness】

Enclosed Fiber Laser Cutting Machine

Better smoke and dust containment

Easier integration with centralized dust extraction systems

Lower noise levels in the workshop

Cleaner and more organized production environment

This makes enclosed machines ideal for modern factories, smart manufacturing lines, and export-oriented workshops.

Open-Type Fiber Laser Cutting Machine

Smoke and dust spread more easily

Requires stronger external ventilation

Noise and sparks affect surrounding work areas

【Automation and Productivity】

Enclosed Type

Fully enclosed machines are more compatible with:

Fully enclosed fiber laser cutting machine with automatic exchange tables

Loading and unloading systems

Unattended or semi-unattended production

High-volume and continuous manufacturing

The closed structure supports stable, repeatable production, which is critical for mass manufacturing.

Open Type

Open machines are better suited for:

Small batch production

Prototyping

Workshops that prioritize flexibility over automation

【Cost and Investment Considerations】

Open-Type Fiber Laser Cutting Machine

Advantages:

Lower initial purchase cost

Simpler structure

Easier access for manual operation

Best for:

Small workshops

Entry-level laser cutting users

Limited budgets

Fully Enclosed Fiber Laser Cutting Machine

Advantages:

Higher safety level

Supports higher laser power

Better long-term productivity

Complies with international safety requirements

Best for:

Medium to large factories

Export-oriented manufacturers

Long-term production planning

While the initial investment is higher, enclosed machines often provide better long-term value through efficiency, safety, and scalability.

【 Which One Should You Choose】

Choose a Fully Enclosed Fiber Laser Cutting Machine if:

You use or plan to upgrade to high-power lasers

Operator safety and compliance are priorities

You want automated, high-efficiency production

Your factory targets international markets

Choose an Open-Type Fiber Laser Cutting Machine if:

You operate at lower power levels

Your workshop space is limited

Budget is the primary concern

You focus on small-batch or custom work

Conclusion

Both enclosed and open-type fiber laser cutting machines have their place in metal fabrication. However, as laser power increases and safety standards become stricter, fully enclosed fiber laser cutting machines are increasingly becoming the preferred choice for industrial manufacturers.

Understanding your production needs, budget, and future expansion plans will help you select the right solution and maximize your return on investment.
