What are best practices for minimum geometry?

Make sure all of the geometry in your laser cut part is at least 50% of the material thickness. As an example, if your material is 0.100” thick, the smallest hole you could expect to cut would be 0.050” in diameter. 

Any interior geometry smaller than 50% of the material thickness will not be cut accurately by the laser, and the integrity of the design will be lost in the machining process. We want to make sure your parts come out perfectly, so we provide all the resources necessary for you to help us make that happen. Our online laser cutting guidelines, max/min material charts, and our support team will give you all the additional information you need.
