Abstract

The invention discloses a 3DP process forming system and an operation method thereof. The 3DP process forming system comprises a rack of a metal frame structure. A modular forming cylinder is arrangedin the rack. A printing device and a powder feeding device are arranged at the position, on the upper portion of the modular forming cylinder, of the rack. The printing device and the powder feedingdevice are connected with Y-direction linear guide rails on the rack through sliding blocks and are used for moving on the Y-direction linear guide rails to carry out powder laying and printing. A part taking auxiliary device is arranged at the top of the rack. A physical curing device is arranged in the part taking auxiliary device. Powder storage boxes are arranged on the two sides of the rack.According to the 3DP process forming system and the operation method thereof, the problem that the uniformity of powder particles laid on a powder bed and the density of the powder bed cannot be guaranteed at the same time is solved, the problem of nozzle blocking caused by raising dust caused by laid powder motion is effectively avoided, and the equipment forming efficiency and the part taking efficiency are greatly improved.

Description

Technical field [0001] The invention belongs to the technical field of 3D printing, and specifically relates to a high-efficiency 3DP process rapid prototyping system suitable for different bonding material systems and an operation method thereof. Background technique [0002] As an important part of advanced manufacturing technology, rapid prototyping technology can effectively shorten the research and development cycle and improve corporate efficiency. Among the many processes of rapid prototyping (such as: FDM, SLA, SLS, SLM, LOM, 3DP, etc.), the three-dimensional printing technology (ie: 3DP process) requires no supporting structure, high molding speed, small equipment investment, and operation and The outstanding features such as low maintenance cost and good environmental adaptability stand out and are considered to have good development potential and application prospects. [0003] 3DP process such as figure 1 Shown. When printing starts, the powder is spread on the workta...
