Molding machine and material are printed, the hardware of printer mainly includes the platform floor component for carrying model, and heating system component is gone up and down flat
Component etc. is moved, the material of insole board is broadly divided into high molecular material material, metal material material, inorganic material material etc., mould
The printing of type must could be completed in substrate, so the adhesiveness of material and bottom plate is the most important condition, influence material and bottom
The factor of plate adhesiveness mainly includes the viscosity of material itself and the molding shrinkage of material itself, if the viscosity of itself is poor,
Then high shrinking percentage can reduce the viscosity of material itself, in FDM-3D printing shaping process, if the poor adhesion of material,
Printer model will appear be detached from bottom plate the phenomenon that, if be partially disengaged, can there is a situation where buckling deformations, can also go out when serious
Now because of warping and cracking the phenomenon that, will affect the progress of printing, this, which is belonged to, is unable to satisfy printing shaping if be all detached from
It is required that the basic demand of printing shaping be summarized simply as follows can normal print and forming model appearance and size it is good, show as
Nothing or micro- warpage are without cracking phenomena.
Industry is printed in FDM-3D at present, PLA material is to need not move through modification to meet the molding requirement of 3D printing,
Along with material has Biodegradable environment protection, so that in the early stage of development of FDM-3D printing technique, PLA material is taken as head
Material selection occupies 60% or more the market share, due to the brittleness and poor heat resistance of PLA material, leads to answering for its printed product
It is relatively narrow with range, it is main at present or based on ornamental class model printing, with the development of 3D printing technique and the demand in market,
Requirement of the people to printing material property is gradually in terms of close to industrial applications.

Property it is also poorer than ABS material, eventually reduce ABS modified material to printing machine bottom board adhesiveness.There is only a few patented technology
It is that optimization is modified to material for the purpose of meeting printing shaping requirement, typically by the way that inorganic particle or low is added
The material of shrinking percentage reduces the shrinking percentage of ABS modified material, and the final ABS modified material that reduces is because shrinking to bottom plate adhesiveness
It influences, publication date is that on 09 15th, 2017 Chinese patent application CN107163426A disclose a kind of low warpage of 3D printing
ABS material and preparation method thereof, although wherein the inorganic particle added has certain reduction to act on the shrinking percentage of material,
The addition of inorganic particle can reduce the adhesiveness of ABS modified material, cause printer model to printing machine bottom board and printer model layer
Adhesiveness between layer sharply declines, and is unable to satisfy the requirement of printing shaping.Only first meet the forming requirements of 3D printing,
The advantage of modification technology can preferably be played.The Chinese patent application CN109206832A that publication date is on 01 15th, 2019,
A kind of ABS material and preparation method thereof of the extremely low warpage of 3D printing without cracking is disclosed, the copolyesters and drop of low-shrinkage are added
The inorganic particle of low material shrinkage, this is the general principle of the prior art, is in addition added to auxiliary crack resistence adhesive, including
PCL, EVA, PE etc., the problem of relating to bottom plate adhesiveness, but these crack resistence adhesives are one-components, with multiple groups
The hot melt adhesive of mixed system is divided to compare, adhesiveness is nothing like, so only booster action, the printing effect that play also are
Extremely low warpage, buckling deformation amount is greater than 1, rather than the effect of micro- warpage.
It is high to disclose a kind of 3D printing by the Chinese patent application CN108148250A that publication date is on 06 12nd, 2018
