Fume Extractor For Laser Cutting

Laser fume extractors capture hazardous fumes and particulate at the source before entering the operator s breathing zone or soiling the laser system.

Fume extractor for laser cutting.

Gather major components and supplies. Fume extraction systems are available in different configurations including exhaust port connection multiple exhaust port connection and standalone source capture. Laser cutting acrylic thermally decomposes the material and produces fumes which are 90 volatiles extremely hazardous the remaining 10 are sub micron particulates. Where there is no mechanical ventilation use natural drafts and position the work to avoid exposure.

Laser fume extractors designed for use with epilog trotec universal boss and glowforge laser cutters and engravers. Cutting disks and rings. Lgacs of different makeup can react in the extreme within the filter separation process. Without such a system you would need to exhaust the voc s out doors much like you would with a residential dryer set up.

Use local exhaust ventilation also called fume extraction for indoor welding. The fume coffin performs this last type of solution it is designed to assist with filtering the exhaust vented from a 50 watt co2 laser cutter. Laser cutting is a non contact cutting technology and it can precisely cut thin semiconductor wafers upto 30mm thick metals. The measured value of 100 cfm meets the minimum exhaust airflow requirement of my particular laser cutter.

See alen corp s article for more detail. Airflow tests of the completed build indicate the net airflow of this system is 100 cfm. These contaminates are known within the industry as lgacs laser generated air contaminates. Never weld in confined spaces without ventilation.

Build a laser cutter fume extractor step 1. In welding laser and plasma cutting applications there are two common ventilation designs most seen in facilities. By installing a fume extraction system you can eliminate these risks and increase morale for your employees. I started out making a jig for my router.

A variety of toxic fumes and particulates are generated when different substrates are being lasered. A laser fume extraction system will connect to the laser machine and filtrate the vocs before recirculating back into the environment. Very high energy laser beam when focused on materials it locally melts the materials and vaporizes it. As with all laser applications if the fume is not removed at source using lev local exhaust ventilation the fume can blur the laser beam affecting its efficiency.

Preventing fumes from causing harm as standard our machines are supplied with an extraction fan unit and two lengths of flexible hosing. Some common laser cutting methods are flame cutting fusion cutting and sublimation cutting.
