Description
Technical field
This utility model belongs to increasing material manufacturing technology field, is specifically related to a kind of cantilevered polar coordinate 3D printing equipment.
Background technology
3D printing technique, i.e. rapid shaping technique (Rapid Manufacturing is called for short RM), refers to pass through continuous print
Physical layer superposition, successively increases material and generates the technology (increasing material manufacture) of 3D solid.Printing is used the most on the market
Material mostly is engineering plastics, and concrete print procedure is that by heating at nozzle, the printed material of solid-state is become molten condition,
Being stacked up from level to level by the printed material that these are melted under the control of computer, the model built the most at last becomes in kind.Now
The most generally occurring that rapidform machine based on Cartesian coordinate type, its motion is real by 3,3 directions of X-Y-Z coordinate
Existing.Z-direction realizes the aspect conversion of part, the processing each layer of part successively.And plane rectangular coordinates lower nozzle X to and Y-direction
Move and realize cross section processing.
In production practices, a lot of products are curved-surface structure such as orthosiss, thin-walled revolving meber etc..Cartesian coordinate type quick
Forming machine, when printing these curved-surface structures, needs to carry out continuous poor complementary operation by computer, when the curved surface printed or
When curve is more complicated, the amount of calculation that computer is carried out is very big, and the circular arc processed by the method, the table of not rounded conic section
Face is approximation, rather than theoretical value.Such as when printing a cylindrical product, utilize the rapidform machine of Cartesian coordinate type
Print track on every layer cross section is not real circle, but replaces the polygon of circular arc with minimum straightway.Due to
The profile of processing curve structure approximates out, and when processing cross section inside and outside circle different diameters and being the least, may result in curved surface
Structure distortion is the most serious.Existing common Cartesian coordinate type rapidform machine can not meet the surface quality of curved-surface structure.
Polar coordinate system refers to the coordinate system being planar made up of limit, pole axis and footpath, pole.Take fixed 1 O in the plane,
It is referred to as limit.Go out to carry out the coffin upon burial ray OX, referred to as a pole axis from O.Taking a fixed long measure again, usual predetermined angular takes counterclockwise
Direction is just.So, in plane, the position of any point P just can be come really with length ρ of line segment OP and the angle, θ from OX to OP
Fixed, there is ordinal number that (ρ, θ) is known as the polar coordinate of P point, be designated as P (ρ, θ)；ρ is referred to as the footpath, pole of P point, and θ is referred to as the polar angle of P point.
In plane, any point rectangular coordinate system and polar coordinate system can be carried out representing in theory, but polar coordinate system is representing
Its distinctive advantage is had when circle and some curves.Such as radius be the circle of 10 method for expressing under rectangular coordinate system be X2+Y2=
100, the expression under polar coordinate system is then ρ=10.Decrease the control to variable with polar coordinate representation, also significantly reduce
The workload of computer, and the track of gained cross section circle be to justify really.
Therefore, for polar coordinates type rapid printer, because it is under polar coordinate system, for curve and the profile of circular arc
It is all one step completed for printing, and substantially increases surface quality, and accelerates print speed, so design cantilevered polar coordinate
3D printing equipment is most important for curved-surface structure part.
