Ortur laser engraving machine produces complex multi-layer engraving works

    In the field of laser engraving, Ortur is known for its high precision, easy operation and rich material compatibility, making it the preferred brand for creators around the world.          Whether it is artistic decoration, industrial logo or personalized gifts, Ortur laser engraving machines (such as Laser Master 3, H10 series) can achieve amazing three-dimensional effects through multi-layer engraving technology.

1. Design preparation: layered conception and software optimization

1. Layered design logic
     The core of multi-layer engraving lies in layered conception. Use professional design software (such as LightBurn, CorelDRAW or Ortur's officially recommended Inspiraesth application) to disassemble the work into background, middle and foreground layers. For example, when engraving a forest scene, you can set the distant mountains as the bottom layer, the trees as the middle layer, and the flying birds as the top layer, and achieve a three-dimensional effect through different depths and powers.
2. Software parameter settings
    Grayscale image processing: Optimize engraving details by adjusting brightness, contrast, and white clipping. The Ortur official tutorial recommends that the M4 dynamic power mode should be used first when grayscale engraving, and the resolution of 15 lines/mm can significantly improve the sense of hierarchy.
    Alignment mark design: Add cross or circular alignment marks to the edge of each layer of pattern to facilitate precise positioning during subsequent engraving. LightBurn's "array copy" function can quickly generate multiple alignment points.

2. Material selection and preprocessing

1. Material adaptability
    Ortur laser engraving machines support 340+ materials, including wood, acrylic, metal, leather, etc. The following combination is recommended for multi-layer engraving:
Wood + acrylic: wood as the bottom layer, acrylic as the transparent cover layer, and light and shadow interaction through edge lighting.
    Stainless steel + anodized aluminum: Utilize the oxidation characteristics of different metals to present gradient colors through power adjustment.
2. Material fixation and pretreatment
    Use a clamp or double-sided tape to fix the material to avoid displacement during engraving. The batch engraving tutorial on the Ortur official website recommends that when multiple layers of materials are stacked, the thickness of each layer must be uniform and compacted with a heavy object.
    Anodizing or sandblasting the metal surface can enhance the laser adsorption force and improve the engraving contrast.

3. Parameter debugging and engraving process

1. Power and speed matching
    Bottom layer engraving: Lay the foundation with a deeper depth and lower speed (such as wood bottom layer: speed 3000mm/min, power S700).
    Middle layer details: Increase the speed (such as 10000mm/min) and reduce the power (S500) to engrave textures or text.
    Top layer highlights: Use the highest power (such as S1000) and the fastest speed (20000mm/min) to highlight the relief effect.
2. Multi-layer alignment techniques
    Physical alignment: Before engraving, apply removable tape to the edge of the material to mark the X/Y axis origin to ensure that each layer is placed in the same position.
    Software alignment: LightBurn's "Camera Calibration" function can automatically correct the offset by identifying the alignment mark through the camera.
Test engraving: Carve a small area first to confirm the superposition effect of each layer before performing the full engraving.

4. Advanced techniques and post-processing

1. Dynamic power and oxidation coloring
    Ortur laser engraving machines support dynamic power adjustment (M4 mode), which can achieve gradual engraving from light to dark in the same layer. For example, through multiple scans and power increases on the metal surface, oxidation colors similar to ink paintings can be generated.
2. Edge lighting and inlay process
    After engraving, engrave a 0.5mm wide groove on the edge of the acrylic layer and embed LED light strips to create a night-time glow effect.
    Use the "Inlay Path" function to generate a positive and negative mold to seamlessly splice different materials (such as wood and metal) to enhance structural stability.
3. Fine grinding and surface treatment
    Lightly sand the engraved surface with 3000 grit sandpaper to remove scorch marks; electropolish metal parts to improve gloss.
   Spray matte varnish or UV protective paint to extend the life of the work and enhance color saturation.

5. Official resources and case references

    Ortur’s official website (www.orturlaser.com) provides a wealth of tutorial videos and parameter databases, such as:
    Material parameter table: covers the best power/speed combinations for common materials such as MDF, plywood, and acrylic.
    User success story: From Christmas decorations to wedding customization, real cases show the flexibility of Ortur laser engraving machines.
    Firmware update: Regularly optimize the engraving algorithm to improve the accuracy and efficiency of multi-layer engraving.

    With the above steps, you can give full play to the performance of Ortur laser engraving machines and transform your creativity into three-dimensional works with layering and artistic sense.
