Cutting technique for bending applications

In this article we focus on the bending of 3 to 5 mm wood and acrylic using the "kerf cut' laser cutting method. Using this method, there is possibility to cut various shapes and geometries resulting in different flexibility output. Trotec has tested various materials and we have selected a few for you where you will also find below the correct templates available for download.

During laser cutting, straight cut lines form a stable radius. The more distance inbetween the individual cutting lines are, the larger the bending radius. Different materials and graphics produce different results, however a distance of up to 0.5 mm between the lines may be selected. 

The flexibility of the material is a result of the interconnection of the small waves. This laser cutting method is suitable for materials up to 3mm thickness. This allows a suffiecient bending radius. 

Using the large Trotec honeycomb table, the curves are tapered at each end and laser cut out of the sheet. This laser cutting pattern is often used in the model making industries. The large area of the honeycombs allows wooden boards up to 5mm thick to be cut and can also be used flexibly.
The honeycombs can be easily pulled apart and pressed together and these properties can be combined easily with connections, for example, with bracelets.

Same as in pattern 1, this cutting pattern mainly entails cut lines, however it does differ in the bending properties, due to it being much more bendable.

In the creation of this living hinge, the demonstrated pattern of this bending cut allows us sufficient flexibility. Application possibilities are thus endless - you can be as creative as you wish here. From hand bags to wine cases - be creative! 

These cuts are all-rounders and work well with many different materials. The shape of the individual cut lines gives stability and flexibility.

Because of the design and flexibility of the material once cut, this cutting pattern can be bent in all directions and due to its design.
The triangular shape of this cutting technique is very suitable for materials up to approximately 3mm. From 5mm material thickness, the bend becomes rigid and inflexible.
