Title: Things You Must Know Before You Start Laser Cutting

Things You Must Know Before You Start Laser
Laser cutting, etching, engraving. It is one of
the coolest ways to bring your designs to
reality. It provides you results with precision,
multi-layered lettering, and design. Laser
cutters are powerful, realistic tools to burn
most things like wood, paper, plastic to create
a design that you imagine. So, before you buy a
laser cutter, keep these five things in mind to
make a precise choice. The Main Choice Laser
Cutter A typical laser cutter that most designers
and engineers use consists of a 100W laser that
have Trumpf nozzles. Between
the lasers extractor fan and sourced materials,
your cost can reach 8000 to construct the whole
setup. If you are just starting, you can even go
for a smaller laser like 40W laser cutters
available online. You can even search for parts
like precitec nozzles or Trumpf parts online to
setup the perfect product for your use. 40W
laser cutter can help you with etching the
designs you want on a thin place of birch
plywood. You can also use acrylic material if
you are looking for some cool opaque effects.
Also, you can retrofit an old DVD players 5W
laser into a working laser cutter if you have
smaller use cases. It can do more than just
etching a design on a piece of paper. How to
Source the Equipment to Build One? In the digital
age, you find many online options for your
requirements. For nozzle parts, you can go for
precitec nozzles, Trumpf nozzles online to
source the best equipment for your business.
Other than that consider referrals from your
circle. They might also work best! What Materials
to Choose? You can not just pick any old material
and start blasting it with a laser. There are
numerous materials like polycarbonate sheets
that produce thick, acrid smoke when coming in
contact with the laser. Also, make sure that you
don't go for
cardboard as much as possible. Because the
focused heat can cause fire easily when dealing
with electrical equipment. Birch plywood is a few
millimeters thick but worth to add material you
can design simply with this material. Your First
Design To find the best designs to start with,
the internet is your bible. Of Course, it does
not mean copying others' work. But you can get
some cool ideas with which you can create your
own designs. You get ready-made SVG files, DXF to
put into a laser cutter software for
printing. General Things for Using Laser
Cutter Power It defines the output power of the
laser. It can be from 0 to 100. Generally, high
power to cut thick materials and lower power to
engrave and cut thin materials. Speed It decides
the movement speed of the laser head. To engrave
and cut thin material, the speed is usually set
to the maximum. Frequency (Hz, PPI) It
specifies the number of laser pulses per second.
For instance, wood cuts are best at 500 to 1000
Hz. For acrylic, 5000 to 20000 Hz is the minimum
requirement. Focus There comes a focus lens
inside the laser head. It should be on the
surface of the material or slightly below for
most of the applications. Make sure that
materials are at a
certain distance from the lens. The exact
distance depends on the type of focus
lens. There are so many types of laser machines
that come with a motorized bed. You can move up
and down to set the focus distance. And the
position of the material surface should be also
manually adjusted. Parts Make sure you are using
the best brand parts like Trumpf nozzles, Amada
laser parts, etc. to get the most accurate
results. Its time to cut! Dont worry, it can
take a few tries to find the ideal settings for
your material. Make sure you change only one
parameter in a test process. For example, do not
forget to write down your current settings for
future reference.
