Photosensitive resin material soluble sacrificial resin

Photosensitive resin material soluble sacrificial resin（Sacrifice Resin）It is a special material specifically designed for 3D printing or micro nano processing, characterized by the ability to decompose or remove under specific conditions (such as heating, solvent dissolution, or light exposure) without affecting the surrounding structure. This material is typically used to manufacture temporary support structures, templates, or sacrificial layers for removal during subsequent processing, thereby achieving more complex or high-precision structures.

The demand for microstructure and material diversity in academia and industry is constantly increasing. SR (Sacrificial Resin) is a resin material that can be used for multiple materials, molding processes, and application scenarios. By combining micro nano 3D printing technology with processes such as flipping and injection molding, the limitations of 3D printing materials can be overcome, allowing for the production of precision devices using materials more suitable for end use applications. Mofang Precision SR (Sacrificial Resin) can be combined with traditional processes such as mold flipping and injection molding,It can break through the limitations of light cured materials in the industrial end and obtain traditional injection molding or directSpecial parts that cannot be produced by 3D printing, such as industrial material components such as PDMS/POM/PP/LCP, can be prepared.

Sacrificial resin mainly plays a role in 3D printing or micro nano manufacturing processesThe function of temporary filling, support, or isolationCommon removal methods include:

thermal degradationAfter heating to a specific temperature, the resin will decompose or vaporize without leaving any residue.

Solvent dissolutionDissolve the resin in a specific solvent (such as alkali soluble or water-soluble solvent) to remove the supporting structure.

photodegradationBy irradiating with specific wavelengths of ultraviolet light or laser, the resin decomposes and disappears.

(1) Micro nano 3D printing and microfluidic chips

inMicro nano 3D printingSacrificial resin is commonly used in manufacturing in the fieldmicrofluidic chipThis type of chip is widely used in biomedicine and chemical analysis. The specific method is to first print the microchannel structure with sacrificial resin, then encapsulate it with another material (such as PDMS), and finally remove the resin to form a fine channel structure. This method can produceHigh precision, seamless microchannelsImprove fluid control accuracy.
