With the continuous development of 3D printing technology, photosensitive resin, as a commonly used printing material, has gradually attracted extensive attention. Photosensitive resin, also known as UV resin, is a material that can be quickly cured and molded under ultraviolet light. In the field of 3D printing, the advantages and disadvantages of photosensitive resins are very obvious.
First of all, the advantages of photosensitive resin are mainly manifested in the following aspects.
1.High precision: Since the photosensitive resin is irradiated by ultraviolet light during the curing process, high printing accuracy can be obtained, especially in terms of detail performance.
2.Smooth surface: Items printed with photosensitive resin have a smooth surface and a high gloss, so they are often used to make products that require high gloss.
3.Wide range of applications: Photopolymer resin can be used in many types of 3D printers and can be used on different printing platforms. In addition, photosensitive resins can also be post-processed through different processing methods, such as sanding, painting, etc., to obtain a more diverse surface effect.
4.Higher strength: Compared with other types of 3D printing materials, photosensitive resins have higher strength and can be used to make parts with a certain load-bearing capacity.
However, photosensitive resins also have some drawbacks.
1.Susceptible to UV rays: Photosensitive resins are prone to yellowing, embrittlement and other problems under ultraviolet exposure, so the service life of items exposed to sunlight for a long time may be affected.
2.Large shrinkage: The photosensitive resin will shrink during the curing process, resulting in a certain deviation between the size of the printed item and the actual design size. Therefore, precise dimensional calibration is required before printing.
3.Pungent odor: Photosensitive resins release a pungent odor during the curing process, which may cause discomfort to sensitive individuals.
4.*Higher: Compared with other types of 3D printing materials, photosensitive resins have higher **, which also limits their application in some fields.
To sum up, photosensitive resin, as a 3D printing material, has the advantages of high precision, smooth surface, wide application range and high strength, but also has disadvantages such as susceptibility to ultraviolet rays, large shrinkage, pungent odor and high quality. In practice, it is necessary to select the right material according to the specific needs and scenarios.
