Abstract

The invention relates to the technical field of 3D printing materials and particularly discloses 3D printing photosensitive resin with high precision, low layer thickness and high performance as wellas preparation and use methods of the 3D printing photosensitive resin. The 3D printing photosensitive resin is prepared from components in percentage by mass as follows: 4.0%-20% of acrylic resin, 4.5%-15.0% of POSS resin, 60%-90% of a diluent, 0.5%-10.0% of a photointiator, 0.05%-2.0% of a free radical inhibitor, 0.05%-2.0% of an ultraviolet absorber, 0.1%-1.5% of a leveling agent and 0.1%-1.0%of a defoaming agent. The 3D printing photosensitive resin has viscosity smaller than or equal to 35 cps at 25 DEG C, has printing precision of 2-4 mu m on XY planes, printing thickness of 2 mu m in the Z-axis direction, transmission depth not larger than 20 mu m and printing tolerance within 25 mu m and is suitable for 3D printing of precision devices.

Description

technical field [0001] The invention belongs to the technical field of 3D printing materials, and in particular relates to a high-precision, low-layer-thick, high-performance 3D printing photosensitive resin and a preparation and use method thereof. Background technique [0002] 3D printing can quickly manufacture three-dimensional parts and carry out design verification or as a functional prototype and production tool. It is an indispensable tool to shorten the product design and development time cycle. It can be used to manufacture complex three-dimensional structures that cannot be processed by conventional molds, so 3D printing is rapidly becoming a standard tool for product design and manufacturing. Also because of its advantages, it has promoted the development of all walks of life. [0003] The basic principle of 3D printing technology can be summarized as laminated manufacturing, which can be divided into the following different technologies: stereolithography (SLA)...
