Description

A kind of five-axle linkage 3D printer mechanism
Technical field
The present invention relates to a kind of five-axle linkage 3D printer mechanisms.Specifically one kind is using digital model file as base Plinth is sliced, with adhesive materials such as special wax material, powdery metal or plastics, the extrusion controlled by parallel institution Head realizes the mobile printing of x, y, z axis, and the lower moving platform of two screw drive controls is realized the rotating print of u, v axis, then used Jointing material from level to level manufactures the 3D printer of three-dimensional object, belongs to 3D printer field.
Background technique
3D printing brings world's manufacturing industry revolution, has overturned traditional production method, needs a kind of achievable multiaxis and beats The 3D printer of print.Traditional 3 D-printing device generally uses worm drive, controls three directions of x, y, z axis of extruder head Movement, working efficiency is low, and because of the limitation of three axis printing and material, object hanging structure occurs and easily collapse, and designs Shortcomings are not able to satisfy multi-field application demand.
The 3D printer of existing maturation only stops the printing of 3 axis, and the application of 3D printing will be greatly expanded in the printing of five axis.
Because constructing object by accumulation manufacture, successively printing, although the very thin section of each layer of printing, in the side X-Y Raising to resolution ratio is very restricted, and will form certain thickness level-one grade " step ", if you need to the object table of printing Face is curved arc, will lead to accuracy error, can just obtain smooth " high-resolution " article in surface by surface polishing;It adopts Suface processing quality can greatly be improved with five-axle linkage 3D printer.
Traditional 3D printer can also use supporter during printing, such as print some objects for having projecting shape, then The material (such as soluble material) for being easy to remove a bit need to be used as supporter.3 axis 3D printers then can not always along A to printing Improve, five-axle linkage 3D printer change A to 90 ° of sides turn direction print, the structural issue of transitional region can be solved.
Summary of the invention
For the above-mentioned problems that 3D printer is existing, the present invention provides a kind of five-axle linkage 3D printer mechanism.Tool Body is said, is the mobile printing that x, y, z axis is realized by the extruder head that parallel institution controls, and two the lower of screw drive control move Platform realizes the rotating print of u, v axis, completes the 3D printer that five-axle linkage prints three-dimension object on lower moving platform.
Present invention provide the technical scheme that
