Cutting techniques associated with acrylic are best for rigid bends, e.g. boxes or cases where the bending radius is very rarely changed. With a continuous load of the cutting pattern, e.g. with a book, the webs can easily break.
When processing acrylic, the following points must be observed:
- A 2” lens (at minimum) should be used for laser cutting with bends. Since acrylic will melt from the heat of the laser beam, if the focal length of the lens is too small, it may result in the cut areas sticking back together.
- We suggest using a cutting distance of around 1-1.5 mm. If melting occurs even with the appropriate lens being used, try increasing the distance between the individual cut lines. However, if the distance used is too large, bend flexibility will decrease.
