Description

A kind of 3D printer

Technical field

The invention belongs to 3D printing technique field, be specifically related to a kind of 3D printer.

Background technology

Existing engineering model such as BUILDINGS MODELS utilizes iron wire or plastics overlap joint stickup to form generally by manual, and this needs to consume a large amount of human and material resources. The BUILDINGS MODELS that particularly some structures are complicated, node is special, the man-hour consumed is more, and the BUILDINGS MODELS assembled is unstable, easily cave in. Additionally, for relatively finer BUILDINGS MODELS, make by hand and be difficult to. Existing engineering model such as BUILDINGS MODELS utilizes iron wire or plastics overlap joint stickup to form generally by manual, and this needs to consume a large amount of human and material resources. The BUILDINGS MODELS that particularly some structures are complicated, node is special, the man-hour consumed is more, and the BUILDINGS MODELS assembled is unstable, easily cave in. Additionally, for relatively finer BUILDINGS MODELS, make by hand and be difficult to. 3D printer is also known as three-dimensional printer, a kind of accumulation manufacturing technology, i.e. a kind of machine of Rapid Prototyping technique, it is based on a kind of mathematical model file, use special wax material, powdery metal or plastics etc. can jointing material, manufactured the object of three-dimensional by the jointing material printed from level to level. Present stage three-dimensional printer is used to manufacture product. The mode successively printed carrys out the technology of constructed object. The principle of 3D printer is that data and raw material are put in 3D printer, and machine can be created product from level to level according to program. The form of the stacking thin layer of 3D printer has varied. 3D printer and maximum " ink " being distinctive in that it uses of conventional printer are out and out raw materials, and the form of stacking thin layer has varied, can be used for the medium wide variety of printing, from various plastics to metal, pottery and rubber-like material. Some printer in conjunction with different medium, can also make that one, object printing is hard and other end is soft. 3D prints and brings worldwide manufacturing industry revolution, it was that can the part design production technology that places one's entire reliance upon realize in the past, and the appearance of 3D printer, this production thinking will be overturned, this makes enterprise not consider further that production technology problem when producing parts, and the design of any complicated shape all can be realized by 3D printer. 3D prints without machining or mould, just directly can generate the object of any shape from computer graphics data, thus the production cycle of greatly shortened product, improve productivity ratio. Although being still left to be desired, but 3D printing technique market potential is huge, certainly will become one of following manufacturing numerous break-through skills. 3D prints and makes people can buy this kind of printer at some electronic product shops, and factory is also carrying out direct marketing. Scientists represents, the use scope of three-dimensional printer is also very limited, but necessarily can print more practical article by 3D printer following people's some day. Existing 3D printer adopts double fan heat radiation, and rack construction is complicated, and fan adopts air draft technology, it is impossible to reaching cooling effect, heat radiation efficiency is low; The physical dimensions such as printhead left and right fixed block are big, make printer head overall weight big; Shower nozzle cannot be changed, easy material leakage; Adopt aluminum shower nozzle easy to wear; The metal easy putty of trunnion etc.
