Never Cut These Using Laser Cutting

Laser cutting is a popular and effective way to cut raw materials but are you aware that not all materials are laser-cutting compatible? It is crucial to know which metals can be safely cut using this method. Cutting the wrong type of metal could lead to disastrous results. In this blog post, we'll explore some of the most common materials that should never be cut using a laser cutting machine and why.


What materials to avoid during laser cutting?



Polyvinyl chloride, or PVC, is a type of plastic that is used in a variety of applications. PVC is strong and durable, making it an ideal material for many different types of products. However, PVC can be difficult to cut with a laser cutter because it can reflect the laser beam. If you are cutting PVC with a laser cutter, it is important to take measures to prevent the reflection of the laser beam.



High-density polyethylene (HDPE) is a plastic made from petroleum. HDPE is strong and resistant to many chemicals. It is used to make bottles, pipes, and other products. Laser-cutting HDPE can release dangerous chemicals into the air. These chemicals can cause cancer and other health problems.


Polystyrene Foam:

Polystyrene foam is often used in laser cutting projects because it is an inexpensive material that is easy to work with. It can be cut into any shape and size, making it perfect for a variety of applications. However, it can be difficult to control the depth of the cut. This can be an issue if you are trying to create intricate designs or need to make precise cuts. Additionally, polystyrene foam can produce a lot of smoke and debris when it is cut, which can be a safety hazard.



Epoxy is a tough, durable material that can be used for a variety of applications but when it comes to laser cutting, epoxy can be tricky. If the epoxy is not properly prepared, the laser beam can cause it to crack or shatter. In addition, the heat from the laser can cause the epoxy to release harmful fumes.


Laser cutting is an efficient and cost-effective way to cut through most materials. However, there are some that should never be attempted with a laser cutter due to their hazardous properties.
