Description
Technical field
It the utility model is related to a kind of rapid prototyping material processing technique field, more particularly to a kind of desktop level 3D printing
Machine.
Background technology
The implementation process of 3D printing is a section and the process successively printed.FDM type desktop levels 3D printer five spends eight
Door, printing principle are material spray superposition printings, and the packing material in closed occupancy is needed when printing closed occupancy so as to packing material
It can not be seen, as long as the material of filling can support outer contour shape.Therefore in printing by set by reduction
Filling proportion just can improve print speed, reduce packing material so as to which shower nozzle just reduces the time of printing packing material, Jin Erjie
Material saving., can be to save the material of internal filling 70% for example filling proportion is 30%, and the time inside printing is also saved
Save 70%.But there is the shortcomings that printing precision reduction to improve print speed by reducing filling proportion, that is, fill
Material is fewer, and printing precision is lower, or even the situation of deformation occurs.Generally fought each other when with 3D printer printer model
It is all different to print the requirement of precision, therefore can be to set the filling proportion of printing according to being actually needed, so as to give work band
Carry out higher efficiency.
The printing precision of 3D printer except with thickness degree set it is directly related in addition to, be also driven motor performance, frame
Frame stability and the influence of complete machine adjustment.The faster shower nozzle of print speed is easier to be offset because of inertia, so as to driving electricity
Machine performance requirement is higher；And framework is also easier to produce vibration, so as to influence the precision of printing positioning.
Often someone will make of floor height or thickness the printing precision standard of printer.The printing precision of 3D printer depends on
In following key element：
1st, whether the running gear in mechanical part is accurate rationally；2nd, whether software control system is reasonable.3rd, cabinet, base
Cannot there are shake or loose phenomenon；4th, the walking attachment structure being flexible coupling of belt or rack with class is not selected, to protect
Do not shaken during card operation, invariant position；5th, machine frame is firm, preferably the cabinet of industrialized production；6th, to select high-quality
Stepper motor and sophisticated software technical support.The running gear that the precision of 3D printer body is depended in mechanical part simultaneously
It is whether accurate reasonable.
Main flow 3D printer is contrasted at present:
Triangular form delta structures：
Triangle is the stable perfect adaptation with cost.In general desktop level printer be exactly nothing but consider it is stable and into
This, natural triangular structure is preferred.The basic characteristics of triangle delta structures are that the side of fuselage is a triangle, three
Angled bottom is used to place hott bed.X-axis is movable in the plane that two Z axis motors are formed, and Z axis is then vertical with fuselage triangle
Straight center line overlaps.It can also move forward and backward with printing objects because hott bed moves forward and backward in Y-axis, beaten so needing to give special heed to
The degree of adhesion for printing object and hott bed is firm.Shortcoming is：The making precision of body is relatively low, is typically only capable to reach mm levels, it is necessary to more
When high precision needs the very big strength to go the printing of debugging, printing objects are with hott bed Y-axis moves forward and backward power supply, control panel is put
Position it is more random.
Cartesian coordinate system type structure includes rectangular box structure and rectangle bar type structure, as described below.
Rectangular box structure:The machine of this structure is the type popularized the most on the market at present, the hair of whole 3D printing
Exhibition comes from the point of view of course, and the machine of this form is also to develop more complete machine, degree of commercialization highest.Feature is that hott bed moves
Dynamic to be moved along Z axis, object is scheduled on the movement for not having XY direction of principal axis on hott bed, so basic do not have to worry printing objects
Occurs misalignment in print procedure.And due to need to only do the movement of XY axles to shower nozzle, mitigate shower nozzle weight can tune and beat
Print-out rate and printing precision.Shortcoming：Installation process is complex, also more difficult screw mandrel, optical axis machining accuracy are high for maintenance, whole
Machine cost is higher.
Rectangle bar type structure:The structure that this structure inherits triangular structure is simple, the motion mode of its XYZ axle with
The motion mode of triangular structure is consistent, so the shortcomings that also inheriting triangular structure simultaneously.The Z of rectangle bar type structure
Shaft step motor is placed on the bottom of fuselage, because the contact area of rectangle bar type structure and workbench is smaller, so will be heavier
Stepper motor be placed on bottom with the center of reducing.Shortcoming：During printing, printing objects move forward and backward power supply, control with hott bed in Y-axis
The position that plate is put is more random.
