The nylon model is composed of white, extremely fine powder particles. The product has high strength and certain flexibility, and can withstand small impact forces.

Resistant to slight bending. The surface of the model presents a frosted, granular appearance with slight permeability. Currently Qi Le has many SLS 3D printers,

The printing materials are mainly nylon PA and nylon plus glass fiber PA+GF.

2. Basic principles, suggestions and strategies
1) Wall thickness

For 3D printing, wall thickness refers to the distance between a surface of a model and its corresponding surface. The wall thickness either makes your wall strong, or

Flexible and easy to deform. In order to ensure the quality of the model, we recommend that the wall thickness be at least 1mm, otherwise the model is prone to holes and rotten surfaces during printing.

2) Model shell
Model shelling is to turn a solid model into a hollow model with a certain wall thickness. If possible, try to shell the model to avoid printing

Deformation and stains are generated during the process, and it can also save printing costs. We recommend that you make two small holes on the model, it is easy to burn out after printing

Pour out the knot powder. Imagine that the powder is flowing, and find the most suitable location to design the small holes for the excess material.

3) Large flat surfaces will cause warpage
Printing a large flat structure is a difficult idea, and in most cases the model will be deformed. This process is called "warping". even if

You add ribs at the bottom of the plane to slow down the printing speed and extend the cooling time, but this problem cannot be solved. The key is to try

Avoid large flat structures.

4) Gap between moving parts
When you design the interlocking structure, the gap between the product surfaces is very important, it will affect the flexibility and bending performance of the product. We recommend

The minimum clearance of the surface is 0.5mm. If you can allow a larger clearance, the clearance between the rings is closely related to the design size you change.

You can leave a large gap for the big ring, and you can print more products in a limited space. For small loops, you must limit the space to ensure

The horizontal and vertical distance between the rings.

5) Assembly
When designing a model that needs to be assembled, it is very important to maintain sufficient gaps between connected parts. The perfect assembly on the software does not mean the actual product

This is because the software does not consider the friction in the real world and the conditions of thermal expansion and contraction. Therefore, different parts combine their use

Environment, leave at least 0.6mm distance between parts to make assembly easier.

6) Concave and concave details
For concave text or surface details, we recommend that the text line width is at least 1mm, the depth is 1.5mm, and the overall height is at least 4.5mm.

The raised text or surface details should be strong enough to not be damaged during printing or transportation. We recommend at least

0.8mm, the overall height is at least 3mm, and the protrusion height is at least 0.8mm.
