Why the glass fiber in 3d printing nylon material accounts for 40%?

First, is that the only kind of 3D printing nylon materials that glass fiber’s ratio is 40%?

Of course not, in 3D printing nylon materials, the ratios of glass fiber usually are 30%, 15% and 40%. Then according to the previous data and experience of E-key printing to judge, it is the highest probability that guests choose to add 30% of glass fiber to print model.

Why the printing 40% of the glass fiber selectivity is smaller? Because the model with 40% fiberglass is slightly brittle, which is also a report based on data from our customers.

Second, what is the difference between nylon plus fiberglass and no fiberglass?

From the material data, the temperature resistance of the 3D printing nylon material added fiberglass will be better. The theoretical data show that it can withstand 148 degrees of heat. However, because the data that the material supplier gives is usually a limit of data, we do not recommend this data. Then in a sound situation, If you choose 3D printing nylon with glass fiber, we advise you that the temperature dose not to exceed 130 degrees, and do not do a long time test. Because this temperature test is usually short, for example, within 10 minutes is OK.

How about it’s hardness? It is 76 Judging from the data. And we can learn from the data that the hardness of the material with glass fiber will probably be 20% higher than it without glass fiber . This is related to the properties of fiberglass. Of course, this is also because guests need to the model with more resistance to higher temperature and strength. And it is recommended to use the materials with fiberglass.

In fact, in the 3D printing industry, printing nylon material called SLS uniformly whether it add glass fiber or not.

Third, what kind of products do the nylon added glass fiber suitable for, what are their characteristics?

This material is more suitable for product functional testing. You can use this material to make some chains and springs that need to bear the strength of activity. Nylon material is permeable, so it absorbs the small dust in the air, and it tends to turn yellow if you put it outdoors in the sun.

The design and the thickness of each model may affect its flexibility. Then we remind that, it usually has the temperature and strength requirements if you choose this material. In terms of surface smoothness, because of the 3D printing SLS nylon material the is made from high-temperature sintering powder, the printed nylon material surface is frosted and unsmooth. If your product has high requirement for the surface , it is necessary to color later. Of course, the painting will be a little more difficult than the resin material printing, so its cost will be higher relatively. The thickness of the printed layer is usually 0.1mm to 0.2mm, and it is thicker than the resin.
