Is it possible to 3D print without fibers?

Learn what thermoplastic pellets are, how it is used in many industries, and the latest trends including bioplastics and sustainable sourcing of raw materials.

At CEAD, our advanced 3D printing technology relies on a variety of materials, with a primary focus on Short Fiber Reinforced Thermoplastics (SFRT). These materials are engineered to optimize the 3D printing on a large scale process and enhance the quality of 3D printed objects most of the time this will result in a higher material price compared to regular injection molding grades.

Next to SFRT, CEAD also has experience in 3D printing with non-reinforced thermoplastics, these materials are usually more challenging to print with and therefore it is important to know the crucial differences between short fiber - and non-reinforced thermoplastics.

SFRT materials feature short fibers with a maximum length of 1 mm. These fibers come pre-impregnated in the pellets we source from our trusted material suppliers.

The inclusion of these fibers serves two critical purposes:

1. Warpage Reduction: SFRT materials are designed to minimize warping during the printing process. This reduces the likelihood of deformities in printed objects.
2. Heat Conduction: Some SFRT materials, such as those containing carbon fibers, efficiently conduct heat away from the print. This heat management capability allows for faster printing speeds.

• While our primary focus is on SFRT materials, we also have extensive experience with non-fiber-reinforced materials. These materials are particularly valuable in applications where transparency or translucency is required.
• Due to the lack of fibers, a smoother surface finish can be obtained while printing with non-reinforced thermoplastics.
• Additionally, they are well-suited for applications where the final product will come into frequent contact with the skin as materials containing glass and carbon fibers can sometimes result in an uncomfortable sensation when in direct contact with the skin, making non-fiber-reinforced materials a preferred choice for such scenarios.

However, it's crucial to be aware of a limitation associated with non-fiber reinforced materials. When used for large 3D prints, these materials are more susceptible to warping. This can lead to internal stresses within the printed object, potentially causing issues like reduced adhesion to the print bed or even cracking under stress.

In conclusion, you can 3D print on a large scale without fibers! non-reinforced materials can have multiple benefits, like transparent or translucent appearances, smoother surface finishes, and can be more pleasant when in touch with the skin. But also beware of the increased tendency of warping, making print defects more likely.
