Why buying a high-quality laser pays off

Published on: 05/06/2020 Author: Alexander Jauker

I regularly see questions or adverts about Chinese laser machines pop up on my various social media feeds. These lasers are often inexpensive, with many of the questions coming from those looking for buying advice or those who do not know what to do with their laser, be it installation, application or servicing.

Chinese laser machines have improved in quality in recent years, with the initial investment being relatively low. However, questions need to be asked, such as what do users get for their money and what are the decisive differences between these inexpensive "entry-level" lasers and comparatively expensive Trotec lasers?

These questions are frequently presented to me and as such I would like to shed some light on the reasons in favour of integrating a high-quality laser machine into your production. A brief summary of the most important points to consider when purchasing a laser cutting or engraving machine can be found below.

  1. The productivity and quality of laser engraving and laser cutting
  2. Running costs: reliability, maintenance and durability
  3. Ease of use and safety

1. Productivity

Trotec laser machines are designed to be production equipment, intended to support users in profitable production. In this instance high-quality components and their smart combination make the difference.

An example of this is the laser source. Laser sources with a ceramic or metal resonator combined with servomotors and steel-reinforced belts enable faster laser engraving of even the smallest fonts across the entire work area. With a glass laser source – usually installed in very inexpensive lasers – it is impossible to achieve a constant engraving result over the entire area of the laser. The diameter of the laser beam increases with the length of the beam path. Purely technically, it’s not possible.

My personal highlight: Speed is productivity. Trotec laser machines achieve an engraving speed of 4.3 m/s and an acceleration of 5g, while inexpensive lasers differ significantly, often only achieving an engraving speed of 0.5 m/s and accelerations around 0.5 g.

Thanks to the Trotec movement system and drive concept, Trotec lasers also bring speed to the material processing, so they engrave quickly and with great quality.

2. Running costs: Reliability, maintenance and durability

Due to the number of cheaper entry level laser machines available on the market, the initial low investment is often appealing to buyers. However it is also important to consider costs beyond the initial layout.

Both the maintenance and running costs are low for Trotec laser machines. This is due in part to technical conditions, such as our InPack Technology, which ensures a closed system where all important components are shielded and protected from dust. Another important factor is the comprehensive range of service packages offered by Trotec. With our TroCare protection package, you can “protect” your laser for up to 10 years and minimise the costs of replacing certain components.

One of the main cost factors to consider is the replacement of the laser source. Generally, the service life of a glass tube is exhausted after 1000 hours, this can be countered by RF laser sources, which last for around 5 years.

3. Ease of use and safety

Trotec laser machines are specifically developed for customer requirements. During development, the Trotec team think of intuitive workflows and integrate software features designed to make calculations easier for the customer, an example of this is the JobTime Calculator or autofocus.

Trotec laser machines are CE-compliant and meet the requirements of the EC Machinery Directive 2006/42/EC. Trotec laser plotters correspond to laser class 2, the safety of your users is guaranteed at all times. Trotec’s production is certified according to the ISO 9001 and ISO 14001 standards.
