Build a laser cutter fume extractor step 1.
Fume extractor for laser cutting.
Gather major components and supplies.
Laser fume extractors designed for use with epilog trotec universal boss and glowforge laser cutters and engravers.
These contaminates are known within the industry as lgacs laser generated air contaminates.
Fume extraction systems are available in different configurations including exhaust port connection multiple exhaust port connection and standalone source capture.
The measured value of 100 cfm meets the minimum exhaust airflow requirement of my particular laser cutter.
Airflow tests of the completed build indicate the net airflow of this system is 100 cfm.
I started out making a jig for my router.
Laser cutting acrylic thermally decomposes the material and produces fumes which are 90 volatiles extremely hazardous the remaining 10 are sub micron particulates.
Laser fume extractors capture hazardous fumes and particulate at the source before entering the operator s breathing zone or soiling the laser system.
In welding laser and plasma cutting applications there are two common ventilation designs most seen in facilities.
Never weld in confined spaces without ventilation.
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.
Use local exhaust ventilation also called fume extraction for indoor welding.
Where there is no mechanical ventilation use natural drafts and position the work to avoid exposure.
If you have a circle cutting jig you can.
Most laser engraving and cutting is done in a closed environment trapping harmful particulate in the work area unless actively vented out or filtered.
Qty 1 55lb bag of activated carbon i called them and spoke to karrie.
A variety of toxic fumes and particulates are generated when different substrates are being lasered.
Laser cutting is a non contact cutting technology and it can precisely cut thin semiconductor wafers upto 30mm thick metals.
Very high energy laser beam when focused on materials it locally melts the materials and vaporizes it.
Some common laser cutting methods are flame cutting fusion cutting and sublimation cutting.
Preventing fumes from causing harm as standard our machines are supplied with an extraction fan unit and two lengths of flexible hosing.
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.
By installing a fume extraction system you can eliminate these risks and increase morale for your employees.
Cutting disks and rings.
