Description
Technical field
The present invention relates to a kind of three-dimensional printer, specifically relates to a kind of Single-nozzle melt-extrusion-type three-dimensional printer.
Background technology
Melt extruded formula three-dimensional printer is also called melt extruded formula fast forming machine, plastic wire material is heated to be molten state by the shower nozzle of this printer, then according to the workpiece Graph Control instruction that computer sends, by the small nozzle in shower nozzle melting charge extruded and be optionally deposited on the workbench substrate of below, forming the ground floor X-Y scheme cross section of workpiece.After this layer of shaping completes, shower nozzle rises a little layer height, carries out the shaping in second layer X-Y scheme cross section according to the similar procedure of ground floor, and this is stacked is added on last layer, and is bonded to each other and is integrated.So repeat two dimension to be from level to level shaped, until whole 3 D workpiece has been shaped.
Above-mentioned forming technology belongs to addition autofrettage, without the need to traditional cutting machine tool and tool and mould, under control of the computer, can direct forming 3D solid according to the three-dimensional CAD model of workpiece, thus be called free forming, be applicable to very much the development of new product, can greatly save man-hour and cost.
Melt extruded formula three-dimensional printer traditional at present has following two features: (1) adopts that roller is secondary to be sent plastic wire material to shower nozzle heating and melting by frictional force and make it extrude from nozzle; (2) adopt two shower nozzles, the moulding material of one of them shower nozzle melt extruded deposition workpiece, forms workpiece; Another shower nozzle extruding laying down support material also forms supporting construction, in order to avoid workpiece caves in and buckling deformation in forming process.The shortcoming caused thus is: the frictional force between (1) roller and silk material is limited, therefore extrudes power and extrudes limited flow, being difficult to the efficient shaping realizing high density workpiece; (2) in each shaping layer, two shower nozzles must take turns to operate and frequently locate, and forming technology is complicated, significantly reduces forming efficiency; (3) every platform forming machine must have two shower nozzles, two charging trays and two mantle fiber material feed mechanisms, makes mechanical construction and control system more complicated.
Summary of the invention
The object of the invention is to overcome deficiency of the prior art, provide a kind of Single-nozzle melt-extrusion-type three-dimensional printer.
In order to solve the problems of the technologies described above, the present invention is achieved through the following technical solutions:
The present invention forms by with lower part: single spraying head tube 1, Multi-stage heating unit 2, feed mechanism 3, transferring material mechanism 4,3 D-printing platform 5, X control and drive system to walking unit 7, Y-direction walking unit 8, Z-direction walking unit 9, printing raw material 10, computer.
Operation principle of the present invention: 3 D-printing workbench 5 be a kind of can realize the space multistories such as top to bottom, left and right, front and rear track route, the motion that controlled to drive platform primarily of X to walking unit 6, Y-direction walking unit 7, Z-direction walking unit 8 by computer.Printing raw material 10 is placed on cylinder, rotate as transferring material mechanism 4 provides transmission materials feed mechanism 3 by cylinder, feed mechanism 3 is a kind of accommodate raw material, and element controls clamping device achieves material reinforcing and transmission by motor, spring, cylinder, wall.Described material is the strip materials such as ABS, PLA, after raw material enters Multi-stage heating unit 2, raw material can be heated, present molten, the concrete place on 3 D-printing platform is printed to by single spraying head tube 1, material can be shaping rapidly, and clamping device can regulate by spring the dynamics accommodated, and single tube shower nozzle 1 achieves the adjustability of print speed.Printer prints the shape of object, come by given graphical three-dimensional modeling, there is CAD 3D modeling just can complete under normal circumstances, the process need of modeling uses computer, by the information that 3-D view generates, be driven in driving data storehouse the three dimensional practicality arrived that can realize printing needs in three-dimensional printer.For three dimensional practicality, the function of different status requirements is also different, and Multi-stage heating unit achieves the control of temperature, achieves the difference of technique, and the temperature of demand the data when modeling can realize the change of temperature.
Compared with prior art, the invention has the beneficial effects as follows:
Present invention achieves is adopt roller pair and wall to realize sending and extrude a material to, by extruding precise hard_drawn tuhes and the process optimization of a material, only needs single shower nozzle just can be formed separately workpiece and supporting construction.Heating unit employing Multi-stage heating unit is realized to the Fast Heating under different temperatures.Relative to traditional three-dimensional printer, there is the advantages such as material extrusion power is large, discharging is stablized, need single shower nozzle just can be formed separately workpiece and supporting construction, forming efficiency is high, workpiece is closely knit, the more compact structure of forming machine.
