The Benefit Of Femto Second Laser Cutting

Femtosecond laser cutting machine is a high-precision, high-speed cutting equipment with a wide range of applications. It is mainly used for cutting various materials such as metals, non-metals, and composite materials. It has fast cutting speed, high precision, and does not generate heat, so it will not have a thermal impact on the cutting material, thus ensuring the cutting quality.

What are the application fields of femtosecond laser cutting machine?

Femtosecond laser cutting service have a wide range of applications and are mainly used in the following areas:

  • – Metal cutting: including cutting of stainless steel, aluminum, copper and other metal materials.
  • – Non-metal cutting: including cutting of various non-metal materials such as ceramics, glass, plastics, etc.
  • – Composite material cutting: including cutting of various composite materials such as carbon fiber and glass fiber.

What is the difference between femtosecond laser cutting machine and traditional laser cutting machine?

The difference between femtosecond laser cutting machines and traditional laser cutting machines lies in their working principle and cutting method. Traditional laser cutting machines achieve the purpose of cutting by generating high-energy laser beams that penetrate the cutting material. The femtosecond laser cutting machine uses femtosecond-level time pulses to produce a high-energy thermal effect on the cutting material in a very short period of time, thereby achieving the purpose of cutting.

What are the common problems in practical applications of femtosecond laser cutting machines?

In practical applications, femtosecond laser cutting machines may have the following problems:

  • – Slow cutting speed: It may be due to incorrect parameter settings of the cutting machine, or the nature of the cutting material is not suitable for the femtosecond laser cutting machine.
  • – Low cutting accuracy: It may be due to incorrect precision settings of the cutting machine, or the nature of the cutting material is not suitable for the femtosecond laser cutting machine.
  • – Poor cutting effect: It may be due to improper operation of the cutting machine, or the nature of the cutting material is not suitable for the femtosecond laser cutting machine.

What cases show the application of femtosecond laser cutting machines?

  • – Metal cutting: Femtosecond laser cutting machines can be used to cut stainless steel, aluminum, copper and other metal materials, and are widely used in automobiles, aerospace, building decoration and other industries.
  • – Non-metal cutting: Femtosecond laser cutting machine can be used to cut various non-metal materials such as ceramics, glass, plastics, etc., and is widely used in electronics, home appliances, craft gifts and other industries.
  • – Composite material cutting: Femtosecond laser cutting machines can be used to cut various composite materials such as carbon fiber and glass fiber, and are widely used in aerospace, automobiles, new energy and other industries.

Relatively low cost, scalable power, and highly reliable, fiber lasers have dominated cutting and drilling applications in the medical device manufacturing industry for many years. Femtosecond lasers have great advantages in cutting quality, but for a long time they have only competed for a small market share. However, as shown in the figure, sales data for Be-Cu rapid prototyping and pipe cutting systems show that this situation suddenly changed extremely quickly. Let’s take a look at what is driving the dramatic growth in femtosecond laser market share compared to fiber lasers.

Achieve better, more precise cuts

The use of femtosecond (fs) lasers for material processing has several unique advantages that have long been known to the public. For conventional lasers like fiber lasers, most of the material interactions are photothermal, which creates a heat-affected zone (HAZ). In precision applications, this limits the minimum size of parts that can be machined cleanly without melting, may result in unacceptable functional or cosmetic damage, and often requires mechanical post-processing work (e.g., deburring, manual polishing or reaming). In contrast, femtosecond lasers deliver pulses that are orders of magnitude shorter and have much higher peak powers, instantly vaporizing the material before heat is transferred to the part. This more precise and relatively cooler cut produces smaller parts without recast debris, so no grinding or polishing is required. Additionally, this method works with almost any material, including mixed-material parts such as polymer/metal coatings (see image).

Miniaturized devices with finer details (like frames)

Growing demand for medical devices with smaller, thinner-walled components and more cutting details, such as peripheral stents, hypotubes, minimally invasive tools, etc., has significantly boosted femtosecond laser machining market share in the near term increase. We see this particularly true for demand for equipment configured for tube cutting geometries such as the one pictured above. In addition, the use of more challenging and expensive materials is also an important driver. An example is magnesium bioabsorbable scaffolds, where post-processing after fiber laser processing may reduce its yield by 50%, while femtosecond laser cutting does not require post-processing. Other industries (e.g., displays/electronics) are also adopting this technology, creating additional market demand and further driving laser manufacturers to develop advanced femtosecond laser systems and machines.

The progress of femtosecond laser——

More power, lower cost per watt

In fact, femtosecond lasers have reached a new level of maturity in terms of performance, affordability and reliability. Power is a particularly important performance parameter, as it directly determines throughput. Be-Cu’s Monaco series belongs to the new generation of femtosecond lasers, and its maximum power has been continuously increased from less than 20 W to more than 60 W during the time range covered by the sales chart. The cost per watt of most femtosecond lasers has also declined recently. As a result, these lasers can not only help increase throughput but also reduce the cost of individual parts. Early Monaco models have been deployed in demanding 24/7 production environments for several years, highlighting the higher reliability of femtosecond lasers, which in turn helps lower total cost of ownership. Combined with the cost savings achieved by eliminating mechanical post-processing steps, this can be a very cost-effective solution for some precision cutting tasks.

Streamlined automated machines

True, most medical device manufacturers want not just a laser, but a complete laser system. The final step in realizing this vision is the availability of advanced femtosecond lasers. Femtosecond lasers enable streamlined, automated part handling and monitoring, along with easy-to-use software that doesn’t require extensive training or expertise to get started. This gives users the flexibility to quickly switch between different devices in small batches, or to run high-volume components unattended for long periods of time. Be-Cu’s StarCut Tube series of machines is an example, which incorporates a completely new operating software: Be-Cu’s frameWork laser software.

The bottom line is: should you choose fiber lasers, femtosecond lasers, or both?

One of the major dilemmas for anyone in the medical device manufacturing industry today when purchasing a new machine is deciding between femtosecond and fiber lasers. Fiber lasers also have the major advantage of being able to cut faster and cut thicker parts because of the higher power available. However, with thinner parts, the power and speed advantages are often compromised due to the need to reduce repetition rates and avoid cumulative thermal damage. So, ultimately, choosing which laser is best really depends on the specific application.

That’s why new lasers for cutting medical devices now include femtosecond lasers, fiber lasers, or even a mix of the two. With the latter option, users can seamlessly switch between the two lasers, even within a single job, as there are situations where cutting with a fiber laser may be more economical than using a femtosecond laser (and vice versa) .
