Dealing with kerf and inlays


I got a big bag of exotic vaneer samples and started trying to cut some inlay veneers. I have a basic coaster design and I’m printing the same design in two different types of wood and then I end up with two coasters that are the same but with inverted wood types. What I noticed is that even though my laser is properly tuned, the kerf is enough to create a noticable gap in the inlay.

Using the stock board and K40 whisperer is there a way I can deal with the kerf in order to create a tighter fit?

When I do veneer inlays I just make sure the cutting and engraving are done at the focus point. The gap tends to be fairly minimal. I also moisten the veneer before clamping which causes the veneer to swell and further reduces the gap. If you want to make the gap smaller you would probably need add a thin contour step for your cut outline. Would need to do this in whatever image software you are using.


Thanks. I’ll try wetting it.

As I use Fusion360 when designing I always add a kerf parameter which I add to all external measurement for parts that will be lasercut… Then i meassure the kerf of the laser for the material i’m going to use and adjust the parameter in Fusion360. That has worked really well so far.

If you use LaserWeb, you can use “Cut inside” and “Cut outside” with a tool diameter of the laser kerf.

Don’t know if this is useful as I have not watched it yet…
