Ortur laser engraving machine achieves high-precision portrait engraving

The Ortur laser engraving machine, with its excellent performance and precise control, can help you achieve creativity from photos to 3D. Next, we will provide a detailed introduction on how to use the Ortur laser engraving machine to create high-precision portrait carvings from an ordinary photo.

1、 Preparation work: Selection of software, hardware, and materials

（1） Hardware preparation

    Firstly, you need an Ortur laser engraving machine. As a well-known brand in the field of laser engraving, Ortur's products have the characteristics of high precision, high stability, and easy operation, making them an ideal tool for achieving portrait engraving. Ensure that the laser head of the engraving machine is clean and the lens is free of dust or stains to ensure the output quality of the laser. At the same time, prepare suitable carving materials such as wood, acrylic, leather, etc. Different materials will bring different carving effects, which can be chosen according to personal preferences and needs.

（2） Software preparation

    The software that comes with the Ortur laser engraving machine is powerful and compatible with multiple image formats. The commonly used software is LaserGRBL, which can easily import photos and set carving parameters. In addition, you also need an image editing software such as Photoshop to preprocess the photos and enhance the carving effect.

（3） Photo preparation

    Choose a high-resolution portrait photo with moderate contrast. High resolution photos can provide more details, making it easier for carving machines to capture accurately; Moderate contrast helps to highlight the contours and features of the portrait. Save photos in common image formats such as JPEG, PNG, etc.

2、 Photo preprocessing: optimizing images to adapt to carving

（1） Adjust image size

    Adjust the size of the photo in the image editing software according to the size of the engraving material. Ensure that the proportion of the image matches the carving area to avoid image distortion during the carving process. For example, if the carving material is a 10cm x 10cm wooden board, then adjust the photo to the same scale size.

（2） Enhance contrast and brightness

    By adjusting the contrast and brightness of the photo, highlight the main features of the portrait, such as facial contours, eyes, nose, mouth, etc. A higher contrast can make the black and white layers of the image more distinct, making it easier for carving machines to recognize different grayscale areas and achieve finer carving effects. In Photoshop, adjustments can be made using the "Curve" or "Scale" tools.

（3） Convert to grayscale image
 

  Portrait carving is usually based on grayscale images, as the laser power of the carving machine can be adjusted according to the grayscale value, thus forming carving marks of different depths on the material. Convert color photos into grayscale images, remove color information, and focus on the brightness and darkness levels of the image. In Photoshop, select "Image Mode Grayscale" to complete the conversion.

3、 Importing software and parameter settings: precise control of carving process

（1） Import photos into carving software

    Open the LaserGRBL software, click the "Import" button, and select the preprocessed grayscale photo. The software will automatically load the image and display it in the workspace. You can place the image in the appropriate position in the carving area through the drag and zoom function.

（2） Set carving parameters

    Laser power: The laser power determines the depth of engraving. For portrait carving, it is usually necessary to adjust the power according to the type and thickness of the material. For example, when carving on wood, lower power (such as 30% -50%) can be used for details, while higher power (such as 60% -80%) can be used for contours and deeper areas. The power adjustment range of Ortur laser engraving machine is wide, which can accurately control the engraving depth of each part.
    Carving speed: Carving speed is closely related to laser power. Higher speeds are suitable for large areas of light colored areas, while lower speeds are used for dark areas and details to ensure sufficient energy output and achieve clear carving effects. Generally speaking, the speed range can be set between 200-1000mm/min, adjusted according to the material and image details.
    Carving mode: Select the appropriate carving mode, such as bitmap mode. In bitmap mode, the software automatically allocates laser power based on the grayscale value of the image, achieving a gradient carving effect from shallow to deep, which is very suitable for rich layering expression in portrait carving.

（3） Preview carving path

Before starting carving, use the preview function of the software to check if the carving path is correct and if the image completely covers the carving area. Ensure that there are no missing or misplaced parts to avoid problems during the actual carving process.

4、 Start carving: focus on details and process monitoring

（1） Fixed materials

    Place the carving material flat on the working platform of the carving machine and fix it with fixtures or tape to prevent the material from moving during the carving process. Ensure that the material surface is perpendicular to the laser head to ensure uniformity in engraving.

（2） Start the engraving machine

    Click the "Start" button in the software, and the Ortur laser engraving machine will start working. At this time, it is necessary to maintain a quiet environment and avoid touching the carving machine or materials to avoid affecting the carving accuracy. During the carving process, real-time monitoring of the carving progress and effect can be achieved by observing the laser carving trajectory.

（3） Dealing with intermediate issues

    If unexpected situations occur during the carving process, such as material displacement, abnormal laser head, etc., the emergency stop button of the carving machine should be immediately pressed to check and solve the problem before continuing the carving. The Ortur laser engraving machine has a comprehensive safety protection mechanism that can effectively ensure operational safety.

5、 Post processing: Enhance the texture of carved works

（1） Clean the surface

    After the carving is completed, use a soft bristled brush or compressed air to clean the debris and dust on the surface of the material, revealing clear carving patterns. For materials such as wood, a damp cloth can be used to gently wipe the surface to remove residual carbonization marks, making the carving effect more vivid.

（2） Painting or polishing (optional)

    According to personal preferences and material characteristics, further processing should be carried out on the carved works. If it is wood, a layer of varnish can be applied to protect the carved surface and enhance its glossiness; For materials such as acrylic, polishing treatment can be carried out to make the surface smoother and more transparent. Through post-processing, portrait carvings can be made more exquisite and have higher ornamental and collectible value.

6、 The advantages of Ortur laser engraving machine: assisting high-precision portrait engraving

    The Ortur laser engraving machine has significant advantages in portrait carving. The high-precision laser head used can achieve a minimum carving accuracy of 0.01mm, accurately capturing every detail of the portrait, whether it is the texture of hair, facial wrinkles, or the charm of the eyes, all of which can be perfectly presented. At the same time, the accompanying software is easy to operate, powerful, and supports multiple image formats and carving parameter settings, making it easy for even beginners to get started. In addition, the Ortur laser engraving machine has strong stability and can work continuously for a long time, ensuring the continuity and consistency of the engraving process.
