Lotus Laser Cutters

Blu70

This model is powered by a 60w DC excited, water-cooled CO2 laser operating at the 10.6μm wavelength. A professional grade recirculating chiller unit is supplied as a part of the package.

The laser source is further protected by a flow sensor that’s not commonly found on

alternative machines at this price point. At 700 x 500mm the working area of Blu70-DC is considerably larger than a typical entry level machine and offers great value for money combining a high output power with a very low entry level price point.

Blu70 has a standard 2” lens with optional, interchangeable lenses of 1.5” and 4” are to provide for a variety of beam profiles and focal point sizes to cover all of the most likely applications.

 

Designed, assembled, configured and tested in the UK to CE and RoHSII regulations, Blu DC is a robust laser cutter from a manufacturer with over 20 years’ experience

Extraction

 

Blu 70 Air Extraction

 

What is Laser Fume?

Lasers are now an essential tool in industry for cutting, marking and engraving a vast range of materials. In virtually all these operations some form of fume is given off as the laser thermally decomposes the substrate to a greater or lesser degree. This fume is a mixture of particulate and gaseous matter.

Fume from materials such as metals and glass is mainly particulate, the majority of which is less than 1µ (micron) in diameter. Organic materials, particularly plastics, produce much more complex fumes which require a greater level of extraction. Most of the particles are spherical and roughly 90% by weight are less than 1µ in diameter. These particles fall within the respirable range and need to be removed from the working environment to prevent bronchial or lung damage. These gaseous organic compounds produced are known as Volatile Organic Compounds, VOC's.

CSI have teamed up with BOFA International to offer a range of self contained fume extraction systems to suit your chosen laser and create a safe working environment.

BOFA AD 500 iQ

The AD 500 iQ mid to high end laser fume extraction system combines extremely large filter capacity with high airflow and pressure rates, making it the ideal choice for heavy duty applications that generate large amounts of particulate and gaseous organic compounds.

Performance has been further enhanced with the inclusion of several features including BOFA’s acclaimed patented iQ Operating System, making the AD 500 iQ one of the most advanced systems available.

 

Standard Features

• high airflow and air pressure values

• Counterflow filter technology

• DeepPleat DUO prefilter

• combined HEPA / gas filter with ACF Technology

• Automatic flow control system

• Airflow measurement in real time

• independent filter state monitoring, display and warnings

• high-contrast display

• 'Safety' operation

• Remote diagnostics via USB

 

 

Optional Features

• intelligent filter technology

• VOC gas sensor (volatile organic connection)

• remote controlled button for stop / start

• signal for filter replacement /system error

• Interface with host laser

• integrated compressor

Direct to Air

Depending location and site requirements it may be possible to use direct-to-air fume extraction for your laser with a simple 'in line' fan or utilise an existing in house system. Please consult with our engineering team to discuss options.

The Vent-Axia is the direct to air, fume extraction unit

FAQ

 

What is a Laser?

The word LASER is an acronym for Light Amplification by Stimulated Emission of Radiation. In basic terms it is a source of light energy that is concentrated in a small area using a series of mirrors and a lens. Rather like concentrating the energy of the Sun through a magnifying glass to burn on a hole in paper on a hot summer's day!

 

What are the advantages with a laser system?

If you are comparing a laser with mechanical engraving then there are several advantages. Laser engravers are generally faster than mechanical systems. They are very quiet and a lot cleaner. There are no mechanical forces used in the engraving process so there is no need to clamp or stick your material to the bed. You don't have to worry about the tool size or how sharp it is, the laser uses the same spot size whether the image is 2.5 x 2.5mm or 250 x 250mm. You can use any typeface on your computer and logos are as easy to engrave as text.

 

How easy is it to use?

Think of a laser as you would a standard printer which you have at home or in the office and that instead of ink you have light energy. You create your image as you would for a normal document in black and white using the LotusCut software, enter the correct speed and power settings for your material and then send it to print on the laser.

 

Do I need to use a dedicated graphic software package?

All Lotus laser systems come with our versatile LotusCut software package which can accept a wide variety of file formats.

 

What sort of images can I engrave or cut?

You can engrave scanned photos, logos, bitmaps, other images, text, and AutoCAD files. Essentially, if you can print it, you can engrave it. To cut, you will need a vector based graphic, such as an .eps or Illustrator file and again if you can create it the laser will cut it! Keep in mind the higher the quality of the graphic you're working with, the better your engraving results

 

What materials can I engrave or cut?

With a Co2 laser you can engrave and/or cut a vast array of materials including paper, card, textiles, leather, wood and plastics to name but a few. With metals a Co2 laser requires the material to have some sort of pre treatment such as lacquer, anodising or compound like CerMark or Thermark. Glass can be marked directly or also with the aid of a compound. Please note that glass or metal cannot be cut using a Co2 laser source.

 

What does a Chiller do?

DC (Direct Current) glass laser tubes can become very hot and cause them to fail. The chiller circulates deionised water around the system keeping it cool.

 

Is it safe to use?

The LotusMark software is Windows based and connected to the laser via USB to a max length 2.5m.

Your standard off the shelf laptop is adequate.

 

Why do I need fume extraction?

When laser marking or cutting materials they will give off some form of fume as the laser thermally decomposes the substrate to a greater or lesser degree. This fume is a mixture of particulate and gaseous matter.

Fume from materials such as metals and glass is mainly particulate, the majority of which is less than 1µ (micron) in diameter. Organic materials, particularly plastics, produce much more complex fumes which require a greater level of extraction. Most of the particles are spherical and roughly 90% by weight are less than 1µ in diameter. These particles fall within the respirable range and need to be removed from the working environment to prevent bronchial or lung damage. These gaseous organic compounds produced are known as Volatile Organic Compounds, VOC's.

Your Lotus Blu laser must have some form of fume extraction fitted. This can be a simple in line fan ducted from the laser direct to open air or a self contained fume extraction system to suit your chosen laser and create a safe working environment.

 

What does the air compressor do?

The air compressor directs a constant stream of air through the nose cone onto your cutting surface to remove heat and combustible gases from the work area, giving better results when cutting.

 

Can I engrave cylindrical items?

No. The Blu systems do not currently have a rotary device option available.

 

Which materials are unsafe to engrave or cut?

Hydrogen Chloride and Vinyl Chloride (mostly found in PVC and other man made materials) are hazardous to the life of your laser system. Engraving and cutting these materials can cause irreversible damage to your machine, so determining the components of your cutting and engraving materials is extremely important. Materials, such as Kydex, contain PVC.

Try to determine the chemical makeup of any product prior to lasering. Where possible request a Material Safety Data Sheet (MSDS). This sheet is designed to provide the proper procedures for handling or working with a particular substrate and contain the elements used to make up the material. It will also indicate whether or not it contains elements that are potentially harmful to you or your engraving system.

 

What is the cost of a laser?

The cost of our various laser systems is determined by the engraving table size, and laser wattage (ranging from 30 watts to 200 watts). They can be bought outright or leased through one of our finance partners. For more information on how to own your own laser please contact our sales team.
