With the development of 3d printing technology, a large number of 3d printers have emerged in China. The more common FDM3d printers, SLA light curing 3d printers, DLP digital light processing 3d printers, metal 3d printers, etc., among which FDM 3d printers are the most widely used, basically It has blossomed everywhere. This is due to its use of 3D printing materials, its price is relatively low, and its use is wide.
Moreover, industrial-grade 3D printers do not have a wide range of applications. Part of the reason is that they are limited by photosensitive 3D printing materials. However, scientific and technological researchers have been trying to make breakthroughs and have made great progress. Next, let’s take a look at the characteristics of several common photosensitive resin 3D printing materials with the editor of Forest Industry Technology.
We first learned that general-purpose resin manufacturers are MADESOLID, MAKERJUICE, etc. However, the color and performance of general-purpose resins are limited to meet market demand. There are only a few colors, such as orange, green, and red.
This resin material is relatively fragile and easy to tear and crack. It is suitable for D LP digital 3d printer. This material resin has many disadvantages, and more scientists are looking for a more durable 3D printing material. Tough RESIN resin 3D printing materials are commonly introduced. This material has achieved a balance between strength and elongation, so that 3D printed prototype products have better impact resistance and strength, such as manufacturing some parts that require precision combined parts The prototype, or the prototype of the snap-on connector.
I believe that many 3d printing enthusiasts have heard of a Daylight resin, which is an interesting 3d printing material. The resins that can be cured under ultraviolet light are different. They are cured under ordinary light, which solves the problem of uv light sources. This reduces DLP digital 3d printers.
Compared with the traditional manufacturing process, which has a complicated and long production process, the design freedom of the jewelry is low due to the received and limited molds. Especially compared with the 3D printing wax mold, there are more mold making processes for the wax mold. The expansion coefficient of this resin cannot be high, and during the combustion process, all the polymer needs to be burned, leaving only the perfect shape of the final product. Otherwise, any plastic residue will cause defects and deformation of the casting.
