Description

A kind of intelligent print system

Technical field

This utility model relates to 3D printer technology field, particularly relates to a kind of intelligent print system.

Background technology

3D printing technique originates from the Rapid Prototyping technique (Rapid occurred the eighties in 20th century Prototyping, RP).Rapid Prototyping technique, also known as free forming technology (Freeform Manufacturing, FM).Its ultimate principle belong to addition manufacture (Additive Fabrication, AF), neither use traditional machining tool and mould, according to the three-dimensional computer Aided Design of workpiece (CAD) model, under the control of the computer by free forming machine direct forming 3 D workpiece.It combines The multiple advanced technologies such as computer-aided design, numerical control, material, are a kind of subversive manufacture Technology.Its ultimate principle is, utilizes computer software that cad model is carried out hierarchy slicing process, Obtain the two-dimensional silhouette information of each bed boundary, generate G-code control routine according to profile information, quickly Forming machine, according to control command, stratified sedimentation material, forms a series of two-dimensional section lamella, finally Fast forming machine makes mutually to bond between lamella and lamella, is piled into by these thin slices progressively laminated structure 3 D workpiece entity.Owing to addition autofrettage is by the three-dimensional conversion to two dimension, make the one-tenth deformation of workpiece Must simplify, it is only necessary to the man-hour of tradition machining 30%-50% and the cost of 20%-35%, just can be directly Make complicated 3 D workpiece, cause huge repercussion in machinery manufacturing industry.

Through the effort of more than 20 years, the key equipment rapidform machine of quick shaping process mainly might be used It is divided into following several, laser curing formula (stereo lithography apparatus, SLA), choosing Select laser sintered (selective laser sintering, SLS), layer separated growth (laminated Object manufacturing, LOM), and fusion sediment shaping (fused deposition Modeling, FDM).The principle of these fast forming machines is substantially and first passes through feeding system in work Layer overlay material on platform, then utilize some big energy devices such as laser material is carried out photocuring or Sintering, feed the most again.The most in layer produce complete workpiece.Fast forming machine is system Making the development of industry and be made that the contribution of brilliance, the particularly design of new product, checking aspect are especially pronounced, But being as the development in epoch, the shortcoming of fast forming machine is more and more prominent.Such as, due to quickly The problems such as the operation principle of forming machine and structure, the material that they are suitable for is the most limited, the limitation of material Property directly results in workpiece and mostly can only be used for sample that body observes rather than can truly use Building blocks of function.Fast forming machine is also had to use these expensive instrument such as laser instrument and vibration mirror Device, so its manufacturing cost is higher, is difficult to promote on a large scale, and thus 3D printing technique arises at the historic moment. Current 3D print system control accuracy needs further to be improved, and is not provided with FPGA module, leads Cause whole system poor stability.
