Laser Cutting

Updated: Dec 1, 2022

In this page, I will describe:

1.The 4 important hazards associated to the operation of laser cutting machine

and their respective safety control measures (administrative/engineering

control).

2.The materials that can be cut and can’t be cut using laser cutting machine.

3.The steps including pictures on the operation of UNIVERSAL laser cutter, that

consist of:

Starting the compressor, turning on the laser cutter machine and fume extractor.
Importing a .DXF file to coreldraw and modify the lines/fill for cutting and engraving.
Sending the coreldraw drawing to laser cutter software and setting the laser cutter power, speed, PPI in the software.
Starting the job on the laser cutter machine.
DOs and DONTs when there’s flame/fire on the material being cut.

4.My Learning reflection on the laser cutter activities.

1) These are the 4 important hazards and the respective safety

control measures on the operation of laser cutting machine:

Hazards	Safety control measures	Pictures
Fire hazard of material catching on fire	In the case of small/negligible fires, users are told to stop the print job and blow the fire out. If that does not work, use the fire extinguisher, and put out the fire (Administrative)	-
Physical hazard of hurting one’s eye when staring directly at the laser beam	Users are told not to stare directly at the laser beam when laser cutter is operational. Instead, take quick looks at it to see if the cut job is going well.	-
Dirty lenses	Ensure fume extractor is on before starting cut job(administrative)	-
Physical hazard of inhaling toxic fumes after Lifting lid immediately	Users are taught to ensure fume extractor is on before starting cut job and to make sure to wait 1min after cut job so all fumes are extracted before opening(administrative)	-

2) These are the materials that can be cut/engraved using laser cutting machine in FabLab:
