1. Preparation checklist for laser engraving leaves
(1) Select leaves with good color that are fully dried for laser engraving. The quality of the leaves will affect the engraving effect. The leaf in this tutorial has been processed.
(2) Place a heavy object on the leaf and let it sit for a while until the leaf becomes flat.
(3) Use a metal plate or LP4 Cutting Plate as a base for the leaf to avoid leaving engraving marks on the machine's base plate during engraving. Use tape to secure the edges of the leaf to prevent it from shifting during engraving.
Using an LP4 Cutting Plate protects the machine's base plate and creates space underneath to prevent heat buildup and reduce heat-induced yellowing on the undersides of leaves.
2. Leaf engraving operation steps
(1) Turn on the machine power and connect the machine via LDS. Import the image to be engraved into LDS software.
(2) Click on the image and click the "Align center" function to place the image in the center, set it to dithering engraving mode, and enable the "invert colors" function.
(3) Preview the engraving and adjust the machine's focus. Adjust the image size according to the size of the leaf. The image width can be equal to or greater than the width of the leaf, but the length should not be too large, leaving some space for taking the leaf after engraving.
(4) Set the engraving parameters. The recommended parameters are: 1K resolution, 55~70% power, and 30~40% depth. Select 450nm blue light as the light source.
(5) Start engraving and check the engraving result.
1. If the leaf is damaged after engraving, it is recommended to reduce the power parameter by 5% until the problem disappears.
2. If the leaf does not have a hollow transparent effect under sunlight, it is recommended to increase the power by 5% until the hollow effect appears.
3. Other tips
Due to the varying thickness and plant fiber structure of leaves, the recommended engraving parameters may not always achieve good engraving results. If the engraving effect is not ideal, it is recommended to use the "material test array" function to test on the leaves and select a suitable range of engraving parameters before engraving.
