3D Mode is one of the functions of LaserPro laser engraver. Instead of traditional two dimensional graphic processing, 3D Mode allows the naked eyes to visualize the curvatures of the 3D effect. Although it is easy to produce 3D samples with LaserPro Engraver, production of the 3D graphic can be a hassle for our users. In this issue of Hot Tips, we introduce a way to produce 3D graphics suitable for laser by using common vector software so that you can also produce graphics full of 3D effects.

Before we introduce the production method, let’s start with the explanation for the principles of how 3D graphics work with the laser engraver. Through the explanation, you will understand the construction of 3D and laser processing better.

Principle for 3D production by laser

3D processing uses degrees of the gray level to adjust the output energy of the laser. Take the figures below as an example. When the color of a certain block is set as 100% black, the laser output energy for processing will be at 100%. The processing depth will be fairly deep. When the gray level is set as 50% black, the laser output energy will be adjusted to a smaller value accordingly so that the processing depth is not as deep.
By specifying the degrees of the gray level in this way, various energy output is achieved and the 3D effects are produced.

By specifying various degrees of the gray level, various energy is output for processing.

Introduction to software for 3D graphic production

Many ways to produce 3D graphics are available. If you are familiar with or frequently use one of the 3D software in the market, you may use it for the production of 3D graphics. After completion, save the 3D images as one of the formats that is compatible with the Laser Engraver (such as JPG or BMP) and let the machine begin the engraving. If you are not familiar with any 3D software, some editing software specific for laser in the market also have 3D mode functionality, which could be a handy tool for you to produce 3D objects. Of course, you may also use Photoshop or CorelDRAW, which you might be using on daily basis, for the production of 3D objects. Ways to produce 3D graphics with these software are not the same. In the following section, we will give you simple illustrations with respect to how these software work.

Laser Professional AP

Currently, quite a few Laser Professional AP’s are available in the market. The users can not only create all kinds of vector images with these AP’s but also convert these vector images into 3D module, which is a great way to produce 3D graphics.

As illustrated in the figure below, all you need to do is to choose the direction of the vector and then set the length and shape of the convex or concave surface. The software will automatically generate the 3D graphic for you.

In addition, you may output the completed graphic directly to the Laser Engraver, which is very handy. You may also export the graphic as JPG or BMP format and then use CorelDRAW or Illustrator, which you probably use frequently, to output the graphic.
Photoshop & CorelDRAW
The way to produce 3D graphics with Photoshop and CorelDRAW is very similar. Fill in the desired gray level colors to each of the drawn figures, and proceed with further arrangement and combination. Then you may output the 3D graphic to the laser for the production of the 3D object. Take the figure below as an example. After producing two graphs in gray level, proceed with the arrangement and combination. Then you may let the laser proceed with 3D mode.

Both Photoshop and CorelDRAW may produce 3D graphics in the manner of combination.

A way to produce 3D graphics

For the production of 3D graphics, in addition to the requirement of having great familiarity with the software, a significant amount of time is required to design and arrange the layout. Thus, we use a relatively simple graphic for illustration so that you would understand how to produce 3D graphics better.

Take the graphic above as a production example. CorelDRAW is used for the production of the 3D graphic.

Step 1. Produce the gray level background

 

LaserPro requests your attention

If you need to produce circular 3D graphics, you only need to select Radial as the gray level type in the pull-down menu of Type. Then, a circular 3D graphic may be produced.

Step 2. Produce three-dimensional characters

Step 3. Edit the characters for the website
Step 4. Combine the 3D images

After finishing the production for each of the objects, you may proceed with the combination of the objects. The combined graphic may be output with the laser engraver.

 
Output the 3D graphic
After selecting the graphic to be output, set the Mode as 3D Mode in the driver. After setting the engraving parameters, output the 3D graphic.

 

Tips for engraving 3D graphics

LaserPro Application Lab provides a few reminders that may require your attention during the 3D engraving in order to improve the result of the engraving.
  • Turn on the Air Assist function
    When the engraving is done along with Air Assist, the depth of the engraving would be deeper. Set Air assist inside the driver by checking the box.

  • Polish
    Dust will accumulate during the engraving when acrylic is engraved. The acrylic may be polished with Polish after the engraving. After the processing, don’t remove the engraved object. Use the Control Panel to lower the platform (for about 7~8 mm) and then engrave once again to achieve the better finish.
  • After engraving the wooden objects, please use a toothbrush with some clean water to remove the dust on top of the object.
