Description
Technical field
The invention belongs to 3D printing consumptive material technical fields, and in particular to it is a kind of can 3D printing hard PVC material and its system
Preparation Method.
Background technology
One kind of 3D printing, i.e. rapid shaping technique, it is a kind of based on digital model file, with powdered gold
Belong to or plastics etc. can jointing material, come the technology of constructed object by way of successively printing.3D printing is typically using number
Technologic material printer is realized.Often be used for modeling in fields such as mold manufacturing, industrial designs, after be gradually available for one
The direct manufacture of a little products has had the parts formed using the printing of this technology.The technology is set in jewelry, footwear, industry
Meter, building, engineering and construction (AEC), automobile, aerospace, dentistry and medical industries, education, GIS-Geographic Information System, building work
Journey, gun and other field are all applied.
The flat objects that normal printer used in daily life can be designed with printing calculator, and so-called 3D printer
Essentially identical with normal printer operation principle, simply printed material is somewhat different, and the printed material of normal printer is ink
And paper, and equipped with different " printed materials " such as metal, ceramics, plastics, sand in 3D printer, it is former material true
Material after printer is connected with computer, can from level to level stack up " printed material ", finally computer by computer control
On blueprint become in kind.Generally, 3D printer is a kind of equipment that " can print " real 3D objects, for example is beaten
A robot, printing toy car are printed, prints various models, even food etc..Why " printing is generically called
Machine " is the technical principle for having references to normal printer, because the process of layering processing and inkjet printing are quite similar.This printing
Technology is known as 3D three-dimensional printing technologies.
There is many different technologies for 3D printing.They the difference is that in a manner of available material, and with
Different layer building establishment portion parts.3D printing common used material has nylon glass, durability nylon material, gypsum material, aluminum material, titanium
Alloy, stainless steel, silver-plated, gold-plated, rubber type of material.
Fused glass pellet (Fused Deposition Modeling, FDM) rapid prototyping technique is a kind of not against sharp
Various silk materials (such as engineering plastics ABS, polycarbonate) are heated fusing and then accumulation molding side by light as the shaping energy
Method, abbreviation FDM.The advantage and disadvantage that FDM has its intrinsic compared with other forming techniques.Advantage：Formed precision is high, printer model hardness
Good, multiple color.Shortcoming：Shaped object rough surface.FDM has its unique advantage compared with conventional fabrication method.First, can manufacture
More fine component of machine.Secondly, the printed matter Products of volume production can reduce production cost to a certain extent.It is more next by price
It is lower, printing cost is more and more lower, increasingly simpler etc. factors of operation, the 3D printer based on FDM forming techniques increasingly by
Consumer is received.At present, 3D printing technique application field is more, medical treatment, building, transport, space flight, archaeology, education and work
The fields such as industry manufacture all relate to.
Theoretical, nearly all can be molded with the polymeric material of melt-processed with FDM, the FDM according to FDM forming techniques
The wire rod of forming technique has very much, such as：ABS, PLA, nylon, PC, PS, HIPS, K glue, PEEK etc. include from general-purpose plastics to
Engineering plastics can be printed with FDM, but the preferable polyvinyl chloride of comprehensive performance (PVC) material never has in general-purpose plastics
For 3D printing, reason is that the thermal stability of 1. hard PVC is poor, and FDM skills can not be also used even if addition organic tin stabilizer
Art prints for a long time；2. hard PVC flows poor, PVC material more difficult discharging in FDM printers, these shortcomings, which cause PVC, not to be had
Have and developed in 3D fields.
