Advantages of carbon fiber 3D printing technology

2024-03-11 15:08

What materials are available for 3D printing? CFR is a process that enables 3D printers to use continuous fiber 3D printing materials to enhance fused process (FFF) parts. Devices with CFR functionality use a dual extrusion system: one for traditional FFF wires and the other for long strands of continuous fibers, laying continuous fibers layer by layer to replace FFF fillers. The parts produced from this will significantly enhance strength (up to 10 times that of any FFF material) and can replace aluminum parts in applications.

Advantages of carbon fiber 3D printing technology

▲ Manufacturing complex 3D geometries at lower costs

Thanks to the slicing and printing process that can automatically generate machine instructions, 3D printers are adept at manufacturing complex geometries. In cutting machines, there is an exponential relationship between complexity and cost: complex 2D geometries require 2-axis or 3-axis CNC milling machines, while 3D geometries require 3-5 axis CNC milling machines. The programming and operating costs of these machines are high, which makes traditional manufacturing design (DFM) guidelines favor the use of parts with lower complexity. If the part is a complex 3D geometry and requires high strength, only CFR can achieve metal grade strength.

▲Highly customizable

The simple process from CAD to parts enables CFR users to quickly change designs to solve specific problems. In traditional manufacturing, manufacturers face the challenge of choosing between low-cost, universal solutions, and very expensive disposable parts. Minor changes often lead to significant cost increases, and fortunately, CFR 3D printing allows users to easily manufacture customized disposable parts.

▲ Low threshold for functional parts

Many 3D printing technologies have achieved customizability and low cost of complex parts, and the unique feature of CFR is that it can also achieve the above characteristics for functional parts. Compared to FFF 3D printed parts, CFR manufactured parts have significant advantages and characteristics, including:

Stronger parts

CFR enables you to dynamically change the strength of parts from plastic strength to aluminum strength. This enables users to design parts with the required strength and perform 3D printing on the parts.

Durability

Due to the high strength, stiffness, and durability of continuous fibers, CFR parts have a longer service life in applications than any other FFF 3D printed parts. In addition, filling plastics also have high wear resistance and toughness.
