Description
Technical field
The present invention relates to 3D printer field, more particularly to a kind of a, CoreXY framves of desktop grade FDM 3D printers
The 3D printer of structure.
Background technology
In 3D printing technique, the mechanical structure of FDM is most simple, and design is also easiest to, manufacture cost, maintenance cost and material
Expect that cost is also minimum, therefore be also to make technology with the most use in the desktop grade 3D printer of household.
FDM melt-laminated molding technologies are by Filamentous heat-fusible materials heating and melting, while three-dimensional nozzle is in computer
Control under, according to section profile information, by material selectivity apply on the table, after being quickly cooled down formed one layer cut
Face.After the completion of one formable layer, machine operation platform declines lower layer of height (i.e. lift height) reshaping, until being formed entire
Solid modelling.
The advantages of FDM technology：
1) operating environment is clean, safe, and material non-toxic can carry out under office, home environment, not generate poison gas
With the danger of chemical contamination.
2) without the valuable component such as laser, thus it is cheap.
3) raw material are spool silk form, save space, are easily portable and replace.
4) stock utilization is high, can candidate materials it is very much, price is also relatively cheap.
FDM 3D printers mainly have 3 kinds according to the kind of drive：XYZ types, CoreXY types and triangular form.
1.XYZ structures
XYZ is clear in structure simple, three axis of independent control so that mechanical stability against short circuit, printing precision and print speed can be tieed up
It holds in higher performance.By three stepper motor independent controls, (some machine Z axis are two motors to three axis, transmission respectively
Synchronous effect).Making is got up, cumbersome, and cost is also higher！
2. triangle
Triangle is exactly the delta described in us, and delta is simple in structure, cheap, and shortcoming is that machine is very big, print space
Less, and stability is poor, and since the coordinate transformation of triangle is the algorithm using interpolation, camber line is with the small straight line of many items
Carry out what interpolating analogue approached, the quantity of small line segment directly affects the effect of printing, causes the lack of resolution of triangle, printing
Precision is opposite to be declined slightly, so leveling is higher to skill set requirements.
3.CoreXY types
CoreXY structures be by Hbot structures improve Lai.The major advantage of Hbot structures, speed is fast, does not have X-axis motor
The burden moved together is also exactly skilful, print area accounting higher of can be made smaller.Existing CoreXY synchronous belts intersect
Operation, limits the speed of service, year-on-year machine type speed, but cannot meet the requirement used.
The shortcomings that FDM technology：
1) forming rear surface is coarse, needs follow-up polishing treatment.Full accuracy is only 0.1mm.
2) speed is slower, because nozzle does mechanical movement.
3) material is needed as support construction.
