I hope that you have read about the the article about different types of Laser Machine, but if not, no worries, I will do a small recap on it.
For our case, to do a Laser Engraving or Cutting Home Business, I will through for the semiconductor laser module and the Gas Laser Machines, CO2.
They are quite good for start a Business at home even they are manufactured in China, they have different powers and prices.
So let’s go start the path for you to do your Laser Engraving Home Business;
RECAP: LASER stands for Light Amplification by Stimulated Emission of Radiation, it is a device that produces highly directional light and it emits light through a process called stimulated emission of radiation which increases the intensity of light. In case of the laser Module they are an optoelectronic device, which converts electrical energy into light energy to produce high-intensity coherent light. In a laser diode, the p-n junction of the semiconductor diode acts as the laser medium or active medium.
The working of the laser diode is almost similar to the light emitting diode (LED). The main difference between the LED and laser diode is that the LED emits incoherent light whereas the laser diode emits coherent light.
Those Laser Module Machines have a range power from 0,5w to 40w, they are good to work at home due to space, and are easy to transport and move around.
Normally, due to the lower price, they are sell just with the frame, Laser module and Arduino board, and their are super easy to build in your desk, but that depends of the frame’s size,
The laser module between 0,5w to 15w range, are most used to engraving materials as plastic, wood, leather and board card and you cut paper up 200g depending of your Laser Module Power.
From 20w input, you can engrave tons of materials and you will able to cut materials up to 6mm as plywood, perplex or leather for example.
Keep in mind, to engrave clear materials as glass, mirror you have a few tricks, that will be explain in one of my Product Post
The high accuracy it offers considers etching more point-by-point pictures and having cleaner cuts.
The creation speed is higher.
A wide scope of materials is cuttable without harming them.
It’s a more moderate alternative contrasted with CNC machines.
It’s viable with any vector programming like AutoCAD (DWG) or Adobe Illustrator (AI).
It doesn’t create squander like sawdust.
Thicker materials are more difficult to cut or require very low speeds.
Higher density materials like glass can’t be cut.
It burns the edges of any material you want to cut.
Some materials, like plastic, can produce toxic emissions.
Production speeds aren’t always consistent, depending on the material thickness and density.
Some laser cutters consume a lot of energy, increasing the production cost
RECAP: In a Co2 laser shaper, light is created when power goes through a gas-filled cylinder with mirrors at the two closures. One mirror is completely intelligent while the other one allows some light to come through. These mirrors manage the laser pillar into the material that will be cut.
These mirrors reflect most of the light traveling through the tube and cause the light waves to build in intensity.
The light only passes through the partially reflective mirror when it becomes bright enough.
Since the light from a laser is infrared, it is invisible to the human eye. It also has a very long wavelength. It can cut a variety of materials, including cloth, wood, metal, glass, and paper. The intense heat from this light vaporizes the material that is going to be cut, leaving an accurate, smooth finish.
Depending on the look you are going for on your material and what material you are cutting or engraving, the speed and power settings can be decreased and increased. Testing your material beforehand is a good practice and will get you closer to perfect results, every time.
Non-Contact Process – The pillar doesn’t actually contact the material it is working with; all things considered, it makes the material dissolve through extraordinary warmth. This makes insignificant harm the material and the machine.
Low Power Consumption – Laser shaper machines have low support costs and just need modest new parts.
A Safer Method – Laser cutting is a lot more secure than different types of cutting since it doesn’t utilize an edge. The actual shaft is fixed in a tight little lightbox.
Unfathomable Precision – Lasers produce profoundly exact and exact cuttings that have clean cuts and a smooth completion.
Numerous Applications – Laser cutting isn’t only for assembling measures – it can likewise be utilized in the clinical area, just as in expressions of the human experience.
The main disadvantages of CO2 lasers are where the advantages of fibre lasers lie.
Firstly, CO2 lasers are sensitive machines that require alignment, so should this get knocked out of place, usually an expert is required to fix it, resulting in long periods of downtime when the laser is not being productive.
This also means they need more regular servicing, and the costs of this maintenance are higher.
Alongside this, more power is needed, resulting in higher electrical costs. CO2 lasers are also slower at cutting thin materials and aren’t able to work with reflective metals to a good degree.
So far, I will only be working with Laser Modules because be cheaper, and due
to not have space at home for the CO2 laser machine.
I love work with Laser Modules because is easier to move them around the house
because the Laser Module is built-in frames, it is easier to work materials of different size,
but because doesn’t have a box can be dangerous for you and who is around you.
You MUST wear Googles to protect your eyes and if you are working
with plastic, don’t do it in closed spaces due to the toxic fumes
On the other hand, CO2 Laser machines give more protection, and because
they are powerful, you can cut and do more amazing
jobs than Laser Modules
