Variations between Laser Chopping and Laser Engraving
Each processes are categorized below the laser marking process. It’s because they use laser marking machines to generate beams that may vaporize half or all of a product. Though comparable, under are some variations between laser slicing and laser engraving:
· Precept of Chopping
Laser slicing includes utilizing a laser beam to chop by means of your complete thickness of the fabric by melting, burning, and vaporizing. Most cuts are excellent. Therefore, they don’t want a second touch-up. Alternatively, laser engraving includes slicing to the specified depth with out slicing by means of your complete thickness. Subsequently, engraved supplies solely have their surfaces vaporized to the required depths.
· Laser Energy
One of the vital vital disparities within the laser slicing vs. laser engraving course of relies on the machines used. Right here, the laser energy is a definitive parameter. On the one hand, laser cutters are machines with a laser energy above 60W. Excessive energy is vital for slicing, though it is determined by the fabric’s sort and thickness. Alternatively, laser engravers have a laser energy under 60W.
The distinction in laser energy additionally restricts the kinds of laser machines appropriate with the method. For instance, most laser slicing machines are fiber or CO2 laser markers. Nonetheless, laser engravers can embrace different laser marking machines, reminiscent of UV or inexperienced lasers.

· Lens Focal Size
One other vital distinction in evaluating the 2 processes is the main target lens used within the laser machines. Laser slicing machines have a lens with an extended focal size. Consequently, they ship clean reduce edges, making them aesthetically pleasing. Alternatively, laser engraving machines have a lens with a brief focal size. Consequently, they offer an object a finer spot measurement, bettering the engraving high quality.
· Chopping Pace
Typically, the laser slicing course of could be very gradual as a result of time and power it takes to utterly vaporize a fabric. Nonetheless, this is determined by the fabric you might be slicing and its dimension. For instance, a skinny steel will take much less time than a thick one, whereas a skinny plastic will take much less time than a skinny steel. Moreover, the gradual slicing velocity ensures that the forefront is clean and of fine high quality.
Laser engraving has the next slicing velocity as the method doesn’t contain slicing. Apart from that, it aids effectivity and discount of contact time. Nonetheless, slicing at an excessive amount of velocity can result in low-quality marking.
· Design File Format
Laser slicing machines use vector design recordsdata, whereas engraving machines use vector and raster design recordsdata.
The vector design format is relevant in laser workings that require skinny traces, and it includes utilizing laser beams to hint the traces and curves of the design vector by vector. Vector design recordsdata could be in EPS, AI, or CDR codecs.
The raster design format applies to laser working supplies reminiscent of wooden, stamps, and papers. It includes constructing the design from pixels and engraving it line by line or level by level. Raster recordsdata are in JPG or PNG format.
· Use of Help Fuel
Help gases reminiscent of helium and oxygen helps in expelling the molten materials seen through the laser slicing course of. Consequently, they’re extremely advisable for slicing thick supplies. Apart from expelling molten supplies, additionally they reduce a clean end look.
Alternatively, laser engraving doesn’t require to help gasoline as a result of it may create a pop that impacts the outlook of the floor end. Nonetheless, you should use it when the engraving course of produces an excessive amount of smoke, because the gases stop the smoke from affecting the marking high quality.
