1. The chemical properties of triethylenediamine (TEDA) and its mechanism of action in 3D printing materials

Triethylenediamine (TEDA) is an organic compound with a unique molecular structure, and its chemical formula is C6H12N2. TEDA molecules contain three nitrogen atoms to form a stable ring structure, which imparts excellent chemical stability and reactivity to TEDA. TEDA has a smaller molecular weight, about 112.17 g/mol, which allows it to penetrate easily into the polymer matrix and exert its unique modification effect.

In 3D printing materials, TEDA mainly plays a role through the following mechanisms: First, TEDA canAs a crosslinking agent, it promotes the crosslinking reaction between polymer molecular chains, thereby improving the mechanical strength and thermal stability of the material. Second, TEDA’s alkaline properties enable it to act as a catalyst to accelerate certain polymerization or curing processes, which is particularly important for photocuring 3D printing materials. In addition, TEDA can react with certain functional groups in the polymer matrix to form stable chemical bonds, thereby improving the interfacial compatibility and overall performance of the material.

These mechanisms of action of TEDA give it unique advantages in 3D printing material modification. For example, in thermoplastics, the addition of TEDA can significantly improve the melt strength and crystallinity of the material, thereby improving interlayer bonding and dimensional stability of the article during printing. In photosensitive resins, TEDA can be used as an additive to the photoinitiator to improve the photocuring efficiency and also improve the mechanical properties of the cured material. For composite materials, TEDA can enhance the interface bonding force between the filler and the matrix and improve the overall performance of the composite material.

2. Application of TEDA in 3D printing materials

The application of TEDA in 3D printing materials is mainly reflected in three aspects: thermoplastics, photosensitive resins and composite materials. In thermoplastics, the addition of TEDA can significantly improve the processing properties of the material and the mechanical properties of the final product. For example, adding an appropriate amount of TEDA to a polylactic acid (PLA) material can improve the melt strength and crystallinity of the material, thereby improving interlayer bonding and dimensional stability of the product during printing. Table 1 shows the main performance parameters of TEDA modified PLA materials.

Table 1 Performance parameters of TEDA modified PLA materials

In terms of application in photosensitive resins, TEDA is mainly used as an additive to photoinitiators to improve photocuring efficiency. For example, adding TEDA to an acrylate photosensitive resin can significantly shorten the curing time and improve the mechanical properties of the cured material. Table 2 compares the light before and after adding TEDAChanges in properties of sensitive resins.

Table 2 Effect of TEDA on the properties of photosensitive resins

In the application of composite materials, TEDA mainly plays a role in enhancing the interface bonding force between the filler and the matrix. For example, adding TEDA to carbon fiber reinforced polyamide (PA) composites can significantly improve the interfacial shear strength and overall mechanical properties of the composite. Table 3 shows the main performance parameters of TEDA modified carbon fiber/PA composites.

Table 3 Performance parameters of TEDA modified carbon fiber/PA composite materials

These application examples fully demonstrate the versatility and remarkable effects of TEDA in 3D printing materials. By reasonably controlling the addition amount and processing conditions of TEDA, it is possible to accurately regulate and optimize material performance for different 3D printing materials and application needs.

3. Preparation process and performance optimization of TEDA modified 3D printing materials

TEDA Modified 3DThe preparation process of printing materials mainly includes steps such as raw material pretreatment, mixing, melt blending and molding. First, TEDA and matrix materials need to be dried to remove the influence of moisture on material properties. Then, TEDA is mixed with the matrix material in a certain proportion, usually using a high-speed mixer or twin-screw extruder for uniform mixing. During the mixing process, strict control of temperature and shear forces is required to ensure that TEDA can be evenly dispersed in the matrix material.

Melt blending is a critical step in the preparation of TEDA modified 3D printing materials. This process is usually carried out in a twin-screw extruder. By precisely controlling parameters such as extrusion temperature, screw speed and feeding speed, the full melting and uniform dispersion of TEDA and the matrix material is achieved. Table 4 lists typical melt blending process parameters.

Table 4 Typical melt blending process parameters

The selection of molding processes depends on the specific 3D printing technology. For melt deposition molding (FDM) technology, the modified material needs to be made into wires suitable for 3D printers; for selective laser sintering (SLS) technology, the material needs to be made into powder. Regardless of the molding process, it is necessary to strictly control the particle size distribution, flowability and thermal properties of the material to ensure the smooth progress of the printing process and the quality of the final product.

Performance optimization is an important part of the development of TEDA modified 3D printing materials. By adjusting the amount of TEDA added and optimizing the preparation process parameters, precise control of material properties can be achieved. For example, in PLA materials, as the amount of TEDA is added increases, the tensile strength and thermal deformation temperature of the material tend to increase first and then decrease, and there is an optimal amount range (usually 0.5-2 wt%). In addition, the comprehensive performance of the material can be further optimized through the use of collaboratively with other additives (such as toughening agents, nucleating agents, etc.).

In practical applications, it is also necessary to consider the environmental adaptability and long-term stability of TEDA modified materials. Studies have shown that the addition of appropriate amount of TEDA can not only improve the mechanical properties of the material, but also improve its heat resistance, weather resistance and anti-aging properties. These characteristics are for the 3D printed products in practical use environmentsBeing able to stay is crucial.
