hello everyone welcome back to PGA chain
design in today's program PJ meets the
pros we have Greg here is going to share
his experience with us for the laser
cutting and laser engraving are you
ready let's get started
my name is Gregory chop Jenn
I've been working at flash basically
since I've grown up into the industry
and I've become interdisciplinary with a
wide variety materials and jewelry
expressions for my designer I mean they
would like to know what kind of a file
is the file that for most of the there's
a ribbon job means most preferably it
would be a dot DXF file that you would
need to see whatever you're working on
as although JPEG files do work but the
resolution and quality of the graphic
will be compromised if they don't meet
what needs to be transferred what is the
lowest resolution we know that higher is
better so let's say I have my dog's
picture now it's going to depend on the
specifics of each picture due to each
picture being individual they're going
to appear differently once they're
transferred on to whatever material
we're processing if it looks like it
will look good due to its appearance as
you see it before our material usually
it will transfer well onto material as
well
but if you can save it as a dot d excel
file that's preferable what about if
some line work so if I want to sound
line where look like engraving right so
only black and white how do I do it you
are doing the illustrator or do I just
and kind of scan what is the best
quality gonna come out from those
evenings regarding line work if you can
work in Illustrator and play with The
Strokes that would be your best option
happy engraving can't go you can achieve
depths of maybe double digit mitts
millimeter or we can do a surface
sketching that is virtually
imperceptible regarding death so the way
I work here is I will inspect a file and
I will relate to client immediately as
to whether or not their vision is
possible so is it possible to work with
like really like light dome surface full
of laser engraving but still have the
really crispy image in there yes so
anytime you have a convex surface you're
going to run the problem the curve is
going to skew or warp whatever it is
that you put atop the convex surface
just as well as a concave surface will
be affected in a similar manner it's
something to keep in mind right so if
you are a cat designer you might wanted
to thinking about what is the best
outcome whether you're gonna do the 3d
printing or you're gonna do laser
engraving if you want to have an image
on top of it right so if it is something
is completely flat laser engraving is
actually become a really nice detail but
if you have some sort of a domed surface
you might want to build it in the cat
and have the testing to do that door
surface to have a better result in
flashing manufacturing here what type of
the metal can you
wait we work with basic alloy material
too precious such as platinum palladium
gold high carat so is there a limitation
the thickness of the material for laser
engraving no for laser cutting we can
cut up to three millimeter reasonably so
that's about a laser engraving and if
you have any questions you can also be
your comment below and I will x-ray to
you no consulting or maybe you will give
us some suggestion and next I would like
to talk about the laser cut so we do
have a laser cut machine here and what
is the capacity I mean how big is this
she can pretty info basically so the
parameters of the bed are eighteen by
eighteen inches and you're looking at
three millimeter tops for thickness to
cut you can go as thin as a quarter
millimeter half a millimeter but just
think practically if it's something that
you're going to do further processing on
you want to make sure that your file is
constructed in a way where you can still
process it without it foiling on you
the laser machine that we have for
cutting is specifically designed for the
jewelry industry it is designed to
process precious metals silver platinum
gold but we're still able to process
more low-grade metals such as brass
aluminum stainless steel it just depends
on what you're looking for but as long
as it can fit within an eighteen by
eighteen bed we just have to discuss the
file I would need minimum a two inch by
two inch plate to work with so for the
laser cut file what kind of file I would
need a dot DXF file if you're able to
have it completely assembled so that it
will go right to cutting what I mean by
that is if you've closed all the spaces
in your design so that it can be
here in peace in order for it to cut out
or if it's not usually I get clients SME
illustrator files and I'm able to adjust
them for cutting how much is it to do
the laser Ingrid so I could start by
giving three different examples such as
let's say a simple wedding band if you
were working within the parameters of
silver 14-karat 18-karat you're looking
at an inside ring engraving starting
from about twenty five dollars again
very non complexity so if people want it
to run along the entire circumference of
the band you're looking at a different
price more often than not I work with
estimates so there is no fee for
consulting contact me and I will be able
to communicate with you in order to find
middle ground regarding what your vision
is and whether or not it's possible okay
secondly let's say you have a flat disc
engraving depending on the complexity
it's starting from twenty five dollars
and then it can go anywhere
over under depending on complexity
thirdly if you have a project that
perhaps you're not sure of the range or
scope of what it could take let's say
you have large volume you need to
duplicate a lot it depends on the
complexity and then the quantity so
pricing will be reflective of that so
also I'm curious and I believe a lot of
my famous curious well laser engraving
and laser cut can do for jury
application I work with a lot of
screenshotted images for example let's
say signatures or doodles or something
of high sentimental value that people
would like
material do you have some simple to show
us what a laser cutting can do for the
jewelry application a best illustration
of it is three examples that we're going
to share with you for example I have a
nameplate that we've cut out named hope
and this nameplate is interesting
because it's only eight millimeters by
four millimeters and dimension so it's
super tiny and it's totally usable as
jewelry another example that's
illustrative is a monogram that we have
which is about an inch by an inch
also thirdly we're able to work on scale
like such where you have stainless steel
that is about two two and a half gauge 2
and 3/4 and you can also similarly get
an output like that
thank you Greg is a lot of good
information that you share with us so
now I have more understanding as a new
designer coming to an industry not just
about 3d printing I also have a laser
cut and these are embedding that I can
utilize and we definitely will contact
you you know the more questioning from
my subscribers so again if you have the
mold question indeed you know you would
come on below and I will excrete for you
thank you again oh the great note Thank
You Jay
okay so we are back here with Matt
Matthew again so this time Matthew can I
talk about laser welding and how in
other applications so Matthew can you
can you like the first question can you
well two different kind of materia
yes you can world gold material together
no problem let's say 14k white 14 karat
yellow what do you think you like making
care yellow no problem or 14 to 18 no
problem
I think a rose gold white to taking care
rose there is no issue but there is one
single issue my recommendation will be
when you have assembly job that you are
assembling something and you welding
together a thinker and 14k my
recommendation will be you can use you
have to use solder and at that point
because the reason I'm saying that
sometimes it's not strong enough to hold
together
what do you mean is having the late
laser to take in place and hope and blow
the solder around it yes okay which it
would be helpful because that way you
have a stronger bond now if two item
let's say you have a partial silver ring
or partial silver bracelet and you want
to weld that silver to go my
recommendation is you can again take it
together strongly and welded in the end
with the solder that's my recommendation
but when you have a weld together with
the solder it will last much much longer
when you saw their white go and yellow
go what solid I use I use the yellow
Rosado
I don't use white solid because white
southern is higher higher because you
have nickel in white saddle right
you mean higher temperature
okay and then you will not you I but
stand still will come very very well
sometimes I get clients to bring they
bring me stand still with silver they
burn together very well but titanium to
stand still or stand still - titanium it
will not bond very well or titanium to
titanium it will not burn what are the
well silver - silver silver - silver you
have to have very powerful laser regular
small lasers will not work for welding
together silver the reason because it
would take lara effort the laser to
generate heat
you know the for to weld it together can
you talk about the laser welding
compared to transitional solder there is
the welding to traditional soldering is
basically when you have an item and you
have a precious stones on earth okay and
a part is broken laser water will be the
number one medication for that
application because it's a local huge
because it's only heats up at one spot
it doesn't heat up all the old ring I
get water repairs coming in like an
antique jewelry or sentimental jewelry
that they are all broken either in
platinum or in in precious gold or gold
filled or all those all those medals I
use laser my
is completed about 85% with lasers last
24 years whatever I record with the
laser none of them came back as redo or
broken a solder come back or tarnishes
the color I think so that's the
difference or let's assume you have a
mother's ring and the mother have
another child they want to add another
stone to the to that existing ring or a
pendant or a bracelet laser will do the
job because you don't have to worry the
other precious stones to be in a heap
can you give us some suggestion what
other things that laser welder can do
for the cheery application whatever it's
broken in the precious mellow it's
fixable with laser okay you can do with
dipping with the laser and a color
stones but you have to have experience
to that if you have a shaky hand if you
see the stuff you can hit the stone and
fragile the stone right the wave breaks
okay but you can you can use free
tipping you can feel pit holes
you can't put you can use for adding
stones or you can use for all kinds of
variety of application that it will help
to work your job faster so that does
increase the speed of oh yes
increase the speed almost 75% Wow okay
yes you would save money so I would like
to thanks Greg and also met again you
know to you know share with those
knowledge with us and welcome back to
check on if we have more question again
if you have a question leave the under
comment below and I'll see you next bye
bye bye bye thank you
