Photopolymer Resins for 3D Printing

Photopolymer resins used for light-curing rapid prototyping are liquid light-curable resins, also known as liquid photopolymer resins, primarily composed of oligomers, photoinitiators, and diluents. In recent years, photopolymer resins have been utilized in the emerging field of 3D printing, gaining favor and attention in the industry due to their excellent properties. Next, we will explore the advantages of photopolymer resins;

In fact, photopolymer resins are a common 3D printing material, also known as UV resins, composed of polymer monomers and prepolymers, featuring high strength, high-temperature resistance, and waterproof characteristics. Photopolymer resins contain light (ultraviolet) initiators, which trigger a polymerization reaction under specific wavelengths of ultraviolet light (250-300 nanometers), resulting in immediate curing. During the 3D printing process, photopolymer resins produce fine details, although they tend to be more expensive. However, they are an excellent choice for printing intricate models.

Photopolymer resins are both an old and a new material. Compared to conventional curing materials, light-curing materials have the following advantages:

(1) Fast curing

Can cure within seconds, suitable for applications requiring immediate curing.

(2) No heating required

This is particularly useful for certain heat-sensitive plastics, optics, and electronic components.

(3) Can be formulated as solvent-free products

The use of solvents involves many environmental issues and regulatory procedures, so every industrial sector strives to reduce solvent usage.

(4) Energy-saving.

Various light sources are more efficient than ovens.

(5) Can use single components, no formulation issues, and long usage cycles.

(6) Enables automated operations and curing, improving the level of automation in production, thereby enhancing production efficiency and economic benefits.

Moreover, photopolymer resins comply with SLA technology materials based on their process principles and the usage requirements of prototype parts, characterized by low viscosity, fast leveling, rapid curing speed, minimal shrinkage, low swelling, and non-toxic side effects.
