Tips to Choose Laser Machine
Laser marking technology is one of the most
important techniques in almost all types of
manufacturing. This is because of the increasing
demand from manufacturers and federal
regulations to track and trace products. One of
the common questions which fabricators ask is
how do they choose the correct laser marking
technology? The truth is, marking and engraving
is not the same thing. There are various

factors which go into choosing the best and
perfect solution for your application. Before
making any important and big investment in laser
marking equipment, consider these three major
considerations and also replace parts like
precitec nozzles or precitec laser head parts.
It will help you choose the best laser
technology 1. Materials Your first step is the
type of material you are going to use for
marking. Break down materials into two major
parts i.e. organic and non-organic. Organic
materials are wood, glass, plastic, or paper
products. Whereas, non-organic materials are
steel, aluminum, or anything which sparks in a
microwave. So, firstly select the type of
material you are going to use. This will give
you the first step of clarity on what you want to
engrave or mark.

• Type of Mark
• Once you decide the material the next you need to
  define is the mark you want to look like. Ask
  yourself with questions like are you looking for
  deep marks? Or do you want contrast marks?
• Depending on the type of marking technology you
  can easily create either dark or frosted marks.
  For example, if you are doing barcode technology
  and struggling with your vision systems ability
  to code then you need to frost backgrounds and
  dark marks.
• Consider safety
• Firstly, you need to think about which part you
  are going to engrave. Will it be on the plant
  floor near operators, do you use enclosed space?
  Will this machine be replacing another type of
  technology like an inkjet?
• Understand that the laser marker location is on
  an open shop floor and your laser supplier will
  help you to install the class 1 safety system.
  It includes a laser safe enclosure, warning
  lights, and curtains to form safe entryways.
• If you have a class IV laser then you need a
  dedicated room. It meets certain safety
  conditions like area posting, protective

• eyewear, and a key switch so that you can still
  meet safety requirements.
• Next up, let's see which type of laser to use
  when.
• CO2 lasers
• Generally, if you want to mark product
  information on organic materials along with a
  non-contrast mark then go for CO2 laser marking.
  With the wavelength of 10.6 microns, it is safe
  to use it in open floor situations. A CO2
  marking machine is a best suitable solution
  while replacing other marking technologies like
  inkjet, dot peen, or labeling.
• Remember, CO2 lasers provide you with a high mark
  quality and are a cost effective solution. They
  are useful for marking date codes, serial
  numbers, and other products like wood, glass,
  rubber, plastics, cardboards, etc.
• Fiber lasers
• If you are marking non-organic materials like
  metal or plastic and want contrast in your mark
  then a fiber laser is the solution. Fiber lasers
  are at 1 micron wavelength, it should be in a
  separate room and enclosed with doors. They
  should follow

the CDRH i.e. Center for Devices and Radiological
Health safety considerations to work in safe
environments. Note Fiber mark lasers offer a
wide range of capabilities and produce high
quality marks. You can easily engrave serial
numbers, bar code, 2D Data matrix, and graphics
on materials like metals, plastics, and
ceramics. Additionally, make sure to use laser
parts like precitec nozzles, precitec laser head
parts, etc. as they are easy to replace. 3.
Diode Pump Lasers If you are marking on plastic
or anodized aluminum with a high contrast mark
then use diode pump laser technology. It has
three times more power than conventional fiber
lasers. This delivers short pulses which creates
clean, crisp marks using minimal surface. Note
Diode pumped lasers deliver razor sharp, high
contrast marks which improves readability.
Additionally, it also increases the traceability
via throughput process.

Conclusion Understanding different laser types
and which to use when is important. We can
understand there are plenty of different laser
machines useful today. And many times it can be
difficult to choose one over another. We hope
this helps you overcome your confusion and helps
you choose the correct laser. This Article Post
