WaterJet Cutting OR C02 Laser Cutting - The Pro's & Con's by Laser Engraving Service

Waterjet Cutting or Laser Cutting? It’s not as simple as you think, both have their benefits depending on the type of material you are working with. Choosing between laser cutting & Waterjet cutting would, therefore, depend on your specification & the project in hand! 

At Laser Engraving Service, we have put together this journal entry to give you the knowledge to make informed decisions on your project. We will be exploring the different processes of C02 & Waterjet cutting;

  • How does it work?

  • The advantages & disadvantage of Waterjet & C02 Laser Cutting

  • What types of material can you cut?

  • What is the thickness of the materials we can cut?

In this journal entry, we will be going over the two methods of cutting with a laser & a WaterJet & looking at the pro’s & con’s & their capability. 

What is WaterJet cutting?

WaterJet Cutting uses a jet stream of pressurized water, which are mixed with an abrasive. At Laser Engraving Service, we use garnet as an abrasive. This method is not only friendlier to the planet; it allows you to cut a wide range of materials, cleanly, to close tolerances and with a clean, crisp edge.  A water jet cutting also doesn’t part rude any heat into a piece. 

So let’s look at what the main advantages & disadvantages are of WaterJet Cutting.

Advantages of Waterjet Cutting

  • On our Waterjet Cutter, we can cut various multiple layers of the same material.

  • Waterjet Cutting is just pressurised water & sand, so no harmful vapors are emitted while Waterjet Cutting.

  • WaterJet cutters can cut virtually any material, including glass and reflective surfaces.

Disadvantages of Waterjet Cutting

Cutting Time –

  • Thickness can lead to less accuracy when you are Waterjet cutting a material – The thicker the material is the further the stream is away from the nozzle at its point of impact. Cutting an uneven surface can change the cutting accuracy from top to bottom. Often, the jet can spread and make more of a diagonal cut than a straight up and down cut.

C02 Laser Engraving & Cutting machine

Our c02 laser machine can be used to either cut or engrave a material by way of a beam that is projected through optics & focused by mirrors into a material which then either melts, burns, vaporizes away. C02 laser cutting or engraving is an affordable, easy-to-use, and versatile tool.

Advantages of C02 Laser Cutting

  • Laser cutting is an amazingly clever way to cut or burn simple to more elaborate designs or motifs into a material.

  • Speed!

  • With C02 Laser cutting, you can achieve a high level of precisions with little wastage, unlike Waterjet Cutting, which has a higher quantity of material wastage during the cutting process.

  • You can both cut & engrave with a c02 laser machine.

Disadvantages of C02 Laser Cutting

  • Limitations to the types of material you can cut or engrave & unlike WaterJet cutting you are unable to laser cut reflective elements.

  • The cutting or engraving process by the laser is created by heat so there is a possibility you could have a residue left from this process.

  • When cutting or engraving a material, it can result in the release of harmful toxins, such as chlorine often found in plastic. At Laser Engraving Service, we only use Perspex graded plastics to prevent the release of harmful toxins.
