A Few Details On Making 3D Printed Models!

The three elements of 3D printing: 3D printing model, 3D printer, and materials, all three are indispensable, each of which has an impact on the quality of 3D printed parts. Today, let’s talk about five key points that affect the printing effect of 3D models.

1. Make your model watertight

The surfaces preparing the model for 3D printing must be joined together with no gaps on the sides. An easier way to test is to imagine: if I fill it with water, will it flow out? It should be noted here that the water injection part is the wall thickness of the model.

2. The wall thickness reaches a certain level

Each side of the 3D model must have a certain thickness, commonly known as wall thickness. According to 3, according to different 3D printing processes, the wall thickness of the model is somewhat floating, but there must be a wall thickness, otherwise, the model will easily collapse during printing.

3. Minimum size

The minimum size is mostly set for details, like some patterns and textures on the model. Different 3D materials have small details that can be achieved during the printing process. Therefore, it is best to understand the 3D printing process in advance when modeling.

4. Model placement

3D printer equipment generally builds objects from small to top, similar to how we stack walls with layers of bricks. Therefore, the stress intensity is similar to that of the wall. Model stress and print locations should be considered when designing.

5. Fill rate

In general 3D printing, solid structures are not printed. Solid structures offer better mechanical properties and durability, but at the cost of increased weight and cost. The fill rate is generally set to fill the interior of the print with a honeycomb structure. In this way, good mechanical properties can be obtained, the weight can be reduced and the cost can be reduced.
