A startup Guide For Laser Cutting
What is Laser Cutting?
Laser cutting is to be known as the process of cutting or engraving material with high powered laser beam by CNC machine.
How does it work?
When u allow a Laser beam to emit through a laser tube & current will pass through it, Then it reflects off mirrors points the beam through the focal lens in machine head. The Lens then focus the laser beam towards the surface of flat sheet material, melting, vaporizing provided with the machine.
This melting & vaporization of material leaves behind the polished edges, requiring little to no finishing
By using the laser cutting, The amount of material removed by the laser beam is very little as compared to the blade or cutting edge. It is totally dependent on the type of material and the thickness of it, for most of the time it is negligible. Laser Cutting Services Offered to give different types of design or marking on different types of material
What can it do?
3 types of techniques are being used for co2 laser machine,
- Vector Cutting
- Vector Engraving
- Raster Engraving
Vector Cutting is the process of full-cut material following the vector line in CAD.
Vector Engraving also is known as “Kiss cuts” is a different level cutting, it is a surface level cut on to the material following the vector line. Which will create an outline on the surface, this is good for adding some details to the design of material
Another type technique is Raster Engraving, it is an infill engrave of a sealed vector shape, in this technique the laser works like an inkjet printer moving from side to side, turning the laser on and off very quickly and slowly moving the lineup,
This CO2 type laser cutting can through a variety of materials, Different types of material cut by CO2 laser cutting includes very thin paper & textiles, plywood, MDF & up to 10mm acrylic plastic. & it also depends on the material quality you intend to use for laser cutting.
Let’s Discuss some of the materials for laser cutting
It is a type of plastic material, which is most common for the laser cutter. The substance called acrylic is actually derived from acrylic acid or related compound. Mostly often acrylic is known to be a glass, which is known as poly-methacrylate (PMMA). Acrylic is extruded into a sheet of various thickness, color & transparency
Acrylic is available in a wide variety of colors & thickness, they are of lightweight & you can also laminate the sheet easily
The negative points of acrylic are, they are quite expensive, brittle & easily scratched
The most common material for laser cutting is wood. Some of the people think that if wood will cut through laser it will catch flame. The laser needs to blow air on the cutting area, this keeps the area cool & remove heat from the wood so that it doesn’t ignite.
Wood is relatively very cheap & easily available, But the negative point is while cutting wood by the laser it burns the edges,
Great product for the laser Cutting is MDF. Because it is manufactured & the more consistent material than wood is MDF. So the performance of MDF Laser Cutting under the laser is more predictable than wood. MDF cuts well. MDF Engraving gives a more 'fuzzy' result.
MDF material is an inexpensive wood & it is a consistent material that always gives predictable results every time
Anodized Aluminum – It can be etched without any problem (Black color anodized aluminum gives the best contrast out of all of the anodized aluminum)
Uncoated brass cannot be used for etching as it gives a lot of reflection. It needs to be painted first before etching
The very beautiful result can be seen on Glass that is etched on the laser By Glass Laser Cutting process. This includes bottles (both full and empty), drinking glasses, and plain flat glass.
Many of the materials can be either cut or engraved with a laser. If you want to try some other materials for laser cutting, here are some of the materials that can be used for laser cutting
