At the beginning, although the manufacturers of 3D printing resin equipment sold their proprietary materials, a large number of resin manufacturers appeared in line with the market demand. At the beginning, the color and performance of desktop resin were very limited. At that time, there were only yellow and transparent materials. In recent years, color has expanded to orange, green, red, yellow, blue, white and other colors.
The photosensitive resin commonly used for desktop 3D printers is a bit fragile and easy to break and crack. To solve these problems, many companies have begun to produce stronger and more durable resins. Make the prototype products of 3D printing have better impact resistance and strength, for example, manufacture some parts prototypes that need precise assembly parts, or prototype of snap joints.
Investment casting resin
The traditional manufacturing process has a complex and long manufacturing process, and the design freedom of jewelry is low due to mold restrictions. Especially compared with 3D printing wax patterns, there are more mold manufacturing processes for wax patterns. The expansion coefficient of this resin cannot be high, and during the combustion process, all polymers need to be burned, leaving only the perfect final product shape. Otherwise, any plastic residue will cause defects and deformation of the casting.
Photosensitive resin material
The performance of flexible resin is a kind of material with medium hardness, wear resistance and repeated stretching. This material is used in the parts of hinges and friction devices that require repeated stretching.
Elastomeric resin is a material that exhibits excellent elasticity under high strength extrusion and repeated stretching. It is a very soft rubber material. It will be very soft when printing thin layer thickness, and become very elastic and impact resistant when printing thick layer thickness. The possibilities of its application are endless. This new material will be used to make perfect hinges, shock absorption, contact surfaces, and other engineering applications, suitable for those who have interesting ideas and designs.
Undoubtedly, high-temperature resin is a research and development direction that many resin manufacturers focus on, because we know that for the field of liquid resin curing, the aging problem of these plastics has long plagued the development of resins into consumer and industrial applications. It maintains good strength, rigidity and long-term thermal stability under high temperature, and is applicable to molds and mechanical parts in automobile and aviation industries. At present, the hot deformation temperature (HDT) challenged by high-temperature resistant resin materials has reached 289 ° C (552 ° F).
Desktop 3D printers are unique in the field of resin with biocompatibility. It is safe and friendly to human environment. The translucency of the resin can be used as surgical material and pilot drill guide plate. Although it is aimed at the dental industry, this resin can also be applied to other fields, especially the whole medical industry.
The ceramics made from these polymers shrink uniformly and have almost no porosity. This resin can produce dense ceramic parts after 3D printing. The super-strong ceramic material that uses this technology for 3D printing can withstand a high temperature of more than 1700 ℃.
Most of the ceramic light-curing technology on the market is to add ceramic powder into a light-curable solution, disperse ceramic powder evenly in the solution through high-speed stirring, and prepare ceramic slurry with high solid content and low viscosity. Then the ceramic slurry is directly solidified layer by layer on the light curing molding machine, and the ceramic parts are accumulated to obtain the ceramic parts. Finally, the ceramic parts are obtained by drying, degreasing and sintering.
Solar resin is different from the resin cured under ultraviolet light. They can be cured under ordinary sunlight, so no longer rely on UV light source, and a LCD screen can be used to cure such resin.
