3D Models for the crystal inner engraving

 

Today’s post is about the 3D model for the crystal inner printing.

When someone is starting the crystal, they may have no idea about the 3D model. Yes, they can do 2D image printing, but the problem is that all the companies that sell this kind of gift do 3D printing, and also, 3D printing is more beautiful. This pushes all the people who come into this industry to go into 3D modeling.

 

About how to get the 3D model, please go to my past post. Today, I want to share something about how to get a model suitable for engraving.

First, let us see what kinds of things will be used for 3D crystal printing. Text, logo, animal, human face photo, and some object structural design drawing.

Yes, let's see one by one.

First, about the text and logo, normally, they are 2D designs. So you can print it just by simply processing it in our dots building software.

Second, an animal, which this normally a cute pet. For this thing, the 3D model is necessary if you want to get a more beautiful effect. Also, not all types of 3D models are useful.

Yes, 3D models also have different types. Different formats and different content will give different effects when engraving.

This time, we need to choose the model that is a photo attached to an obj. We need the photo to get the brightness and contrast.

For the human face photo, it seems like an animal. It also needs the model that a photo is attached to an obj.

The uniform effect eliminates any degree of contrast on the surface of the object. At the same time, the uniform front-to-back effect creates a perspective effect on the model. This is very suitable for showing the structure of the model.

 

And in some ways, the photo attached to the obj will give a 2.5D effect. While the STL gives the 3D effect. If you want to give a very beautiful font effect, the 2.5D effect is important. In theory, we use the variation of light and shadow to show contrast. If the front and back of the model are filled with dots, the surface will lose contrast. For portraits and image models, it is crucial to remove the dots behind them.

 

After I have explain clearly about the model. Now we also want to say more words about the decision to choose the method to get the 3D models.

First, we should know that it is not easy to get the suitable 3D model. So in the market, there are service supplier supply this kind of service. The big crystal 3D gift company will pay to get the 3D model, because the have very big demands for 3D models. Use the third party to do the 3D model can help them processed the production speed.

While there are also some small businessmen. They may purchase a small machine for part part-time business, or some hobby. This way, it is not a small cost if they pay the 3D model service fee. So they may try to do the 3D model themselves. Someone may choose a 3D camera for a crystal 3D machine; some may learn to use the very professional 3D model-building software.

These are real experience sharing about the crystal 3D models. Maybe only useful for people who are considering coming into this industry.

 

At last, sharing a beautiful sample.
