Engraving area and the crystal area for the crystal 3D laser machine

 

Recently, we found many customers have questions about the engraving area for the Crystal 3D laser machine. So this post is for the engraving area.

With the engraving area, I have to mention another word “crystal size”.

 

When we view a machine's parameters, we will first notice the engraving area. This is a very important parameter for machines. Sometimes, we will price the machine according to its engraving area. But what does the engraving area really mean and what you can achieve with your machine engraving area?

This post is for someone who doesn’t have knowledge of the lens, galvanometer, and movable platform. Someone who knows this well can go forward to another post.

Let me first give a brief introduction to it. The engraving area means the size of the image you can print into the crystal. The crystal size means the suggested biggest crystal you can put into this machine, please note it is just suggested, sometimes can be bigger.

 

Engraving area

For now, the engraving size means the maximum size of the image you can engrave.

Different lenses have different engraving areas. As you may know, the lens is a circle, so the engraving area should also be a circle. When there is no movable table, the engraving area for the machine should be the engraving area for the lens.

However, when the machine has a movable table, the engraving area will be different.

Below the table, there will be the motor(s) to move the crystal under the working area of the lens. Besides, there I would like to mention that the motor has the stepper motor and the servo motor. The Japan servo motor should be a better choice.

Motors with different strokes, platforms, and lenses of specific sizes. All these can achieve specific engraving areas.

Oh, I almost forgot the software, the software is also the core part of making the big-size image. When we need to use the movable platform, we usually need to partition the big image into different small pieces and engrave them one by one. So how the software parts the image will affect the quality of the engraving image.

 

 

 

For the crystal size

When we refer to "crystal size", we are usually referring to the maximum size that is recommended to be placed on the table. This recommendation ensures that there is not too much blank edge around the crystal.

 

The largest crystal that can be used in the machine is determined by the size of the machine. This is usually much larger than the "crystal size".

 

 

 

While you can put larger crystals into the machine, the engraving will only work on the maximum engraving area. Therefore, the final product may not look as good due to the large amount of empty space within the crystal.
