Description

technical field [0001] The invention belongs to the technical field of 3D printing, and in particular relates to an FDM type polyetheretherketone high-temperature 3D printing device. Background technique [0002] 3D printing technology is also called "rapid prototyping technology" or "additive manufacturing technology". It is a three-dimensional configuration processing method based on computer graphics files and accumulating materials layer by layer. Since its development, 3D printing has been widely used in education, automobiles, machinery, aerospace, industrial design and other fields, and is known as "the product of the third industrial revolution". According to different molding methods, 3D printing can be divided into stereolithography (SLA), selective laser sintering (SLS), fused deposition modeling (FDM), layer-by-layer build-up modeling (LOM), etc. Currently the most widely used is FDM rapid prototyping. Compared with other 3D printing technologies, FDM can minimi...

AI Technical Summary

Problems solved by technology

Due to the singleness and limitation of materials, many high-performance special engineering plastics such as polyether ether ketone (PEEK) are rarely used in 3D printing, and PEEK parts are expensive, and traditional machining methods are not suitable The cutting allowance is large during the processing of few parts, which will lead to great waste and loss

In addition, the processing temperature of PEEK consumables is as high as 350°C, and the cooling and forming process is greatly affected by the ambient temperature. Conventional 3D printers cannot provide a suitable temperature range, and often cause large deviations in the size of printed parts due to untimely heating and melting and too fast cooling process. , which seriously affects the product qualification rate
