Infrared lamps applied in the 3D printing industry

Infrared lamps applied in the 3D printing industry

2025-04-25
The application of infrared heating tubes in 3D printing has improved industry processes and further promoted the rapid development of 3D printing. At present, material extrusion is the most widely used technology in polymer additive manufacturing or 3D printing.

This process is commonly referred to as melt deposition modeling or melt wire manufacturing, and has been mainly used for 3D printing of thermoplastic materials, polymer blends, and composite materials. But this manufacturing process also has its drawbacks, which are that the functional use of these components may be limited by mechanical anisotropy, where the strength of the printed components across continuous layers in the construction direction (z-direction) may be significantly lower than the corresponding in-plane strength (x-y direction). This is mainly due to the poor adhesion between printing layers, and the reason for this result is that the lower layer has a lower temperature than the glass transition temperature before depositing the next layer. The glass transition temperature can be understood as a melting point similar to metals, but for plastics, this is a range. Using infrared heating to increase the surface temperature of the printed layer just before depositing new materials can improve the interlayer strength of the component.
