Three-dimensional (3D) printing technique is the one of rapid shaping technique, and its common print procedure is: first by microcomputer modelling software modeling, then the threedimensional model " subregion " built up is become cross section successively, namely cuts into slices, thus instructs printer successively to print.The material of three-dimensional printer mainly includes powdered-metal or plastics etc. can jointing material.
Rapid shaping technique in the market is mainly divided into fusion stacking forming technique (FDM), three dimensional printing technology (3DP), stereolithography techniques (SLA), precinct laser sintering (SLS), laser formation technology (DLP).Melted extrusion modeling forming technique (FDM) is a kind of technical matters conventional in three-dimensional printing technology, principle utilizes thermoplastic, polymeric materials in the molten state, melted material is squeezed out from shower nozzle, melted material is met cold after coagulation and is formed the thin layer of contour shape, then superposes layer by layer and finally form product.The polymeric material that melted extrusion modeling forming technique is commonly used the most is in the market acrylonitrile-butadiene-styrene terpolymer (ABS) and PLA (PLA), also has the material such as nylon (PA) and Merlon (PC) in addition.
The melt temperature of printed material PLA is 200 DEG C to 205 DEG C, and ABS melt temperature is about 220 DEG C, in the three-dimensional printer course of work, ABS or PLA is from after shower nozzle is expressed to workbench, melted material starts to be converted into solid-state, film layer structure now on a workbench and adhesive force can be produced between the contact surface of melted material, along with melted material slowly from molten state become solid-state after, adhesive force can weaken gradually along with the temperature of material reduces, but, printing objects inside and outside between there is certain temperature difference, under thermal stress effect, being separated with platform easily appears in the marginal portion of the object after printing, the situation of warpage, thus affect the exquisite degree of printing objects.
Therefore, strengthen the adhesive or adhesive force of melted material and workbench contact surface, thus prevent the phenomenon of printing objects warpage from being that those skilled in the art need the problem overcome badly.Usually one deck pad pasting can be pasted in marker's station in prior art; but; printed material directly can infiltrate the inside of paster as PLA (PLA) and stick together with paster after high-temperature fusion; after printing objects is cooled to room temperature; because printing objects and paster are sticked together, therefore not easily take off.Need in real work with scuppit, object to be separated with paster, such operation certainly will easily destroy object and paster, and with regard to needing, the paster of workbench is changed after often completing one or pieces printing article, and the technique changing paster in real work is loaded down with trivial details, cost significantly improves.
