Description
Technical field
The present invention relates to 3D printing technique field, in particular to a kind of minimizing technology of residual printing silk, FDM printing dress
It sets, storage medium and processor.
Background technique
FDM melting layer deposition modeling technology is one of 3D printing, is by Filamentous heat-fusible materials heating and melting, together
When three-dimensional nozzle under control of the computer, according to section profile information, on the table by the coating of material selectivity, quickly
A layer cross section is formed after cooling.After the completion of one formable layer, workbench declines lower layer of height (i.e. lift height) reshaping,
Until forming entire solid modelling.
For FDM printer after power-off printing or time-out printing, the printing silk of spray head inner molten can be in inertia and gravity
Under the action of mass flowing nozzle 1, form one section of cured residual printing silk, and hang on nozzle.When printing again, sprayed if do not done
The cleaning of mouth, the residual printing silk that this section flows down can adhere on printout, simultaneously because molten chamber (in Fig. 1, trunnion B point to C
Point is defined as molten chamber) in material vacancy, printout has apparent defect in joining place.When serious, cured residual printing
Silk can take the inside of printout to, cause the height of printer section position to get higher, when nozzle is moved to this position, can scrape
The case where part of protrusion, causes the stepper motor stall or step-out of XY axis, and at this moment printout just will appear staggered floor causes to beat
Printed document is scrapped.
Existing printer, especially partially industrialized FDM printer all configure mechanical screeding device, before printing again,
First heating nozzle, then spin, then the printing silk of discharge is scraped completely with mechanical scraper device.Increase mechanical scraper device no doubt
It can complete to clear up remaining printing silk, fill the function of molten chamber, but it not only increases mechanical complexity, also adds into
This.
Summary of the invention
To overcome the above deficiencies, the invention provides a kind of minimizing technology of residual printing silk, this method benefits
Molten chamber is filled, it is ensured that print rear nozzle not again with the characteristic of melt flow stream and the effect of gravity to remove remaining printing silk
Residual printing silk can be flowed out, is scrapped so as to avoid printout, improves product qualification rate.
The present invention also provides include the residual printing FDM printing equipment of silk minimizing technology described above, storage medium and
Processor.
The present invention overcomes the technical solution used by its technical problem to be:
A kind of minimizing technology of residual printing silk, comprises the following steps that
S1, when receive print again request when, spray head leaves former print position and is moved to predetermined initial position；
S2, printer execute the instruction of heating nozzle, then temperature needed for spray head is heated to fusing printing silk executes first
Secondary to instruct into silk, spray head after heating will melt intracavitary residual printing silk fusing, and for the first time into printing silk will residual printing
Silk squeezes out molten chamber；Second is executed again to instruct into silk, second into printing silk by first time into the printing silk being melted after silk
Squeeze out molten chamber；
S3, the instruction for executing pumpback processing promote printing silk opposite direction, so that melting intracavitary portion forms part void spaces, return
The silk of pumping is no longer adhered with the silk to have spued, and air is intracavitary into melting；
S4, execute third time into silk instruct, for the third time into printing silk start to fill molten chamber, the silk to have spued is automatically from nozzle
It falls.
Further, further include step S1 ' before the step S2: print platform is adjusted to apart from printout be normal
The height of printing.Purpose can be directly printed again when spray head is moved to former print position, no longer needs to take time to adjust
Position between print platform and printout, the printing this period silk otherwise adjusted may be flowed out inside nozzle,
It not only may cause waste, be more crucially likely to result on printout there are gap, influence printout appearance and even cause
Printout is unqualified.
Further, further include step S5 after the step S4: executing the instruction of spray head return, spray head leaves predetermined first
Beginning and is moved to former print position at position, during spray head is mobile, executes the 4th time and instructs into silk, when molten chamber fills up, again
Start to print.
Further, in the step S2, second of the speed into silk is greater than the speed into silk for the first time.Purpose is to guarantee
Within this extremely short time second into printing silk be not melted substantially and as early as possible first time into the silk being melted after silk
Squeeze out molten chamber.
Further, in the step S3, the speed of pumpback is greater than second of the speed into silk.Guaranteeing stepper motor not
Under the premise of step-out the speed of pumpback has to fast and is greater than second of the speed into silk, it is therefore an objective to ensure to melt intracavitary be melted
Silk is few as far as possible.
Further, in the step S4, for the third time into the speed of silk than first time into silk and second into the speed of silk
It is all slow.
Another embodiment of the invention additionally provides a kind of FDM printing equipment, using as described in any one of the above embodiments residual
Stay the minimizing technology of printing silk.
Another embodiment of the invention additionally provides a kind of storage medium, and the storage medium includes the program of storage,
Wherein, the minimizing technology of residual printing silk described in any of the above embodiments is executed when described program is run.
Another embodiment of the invention additionally provides a kind of processor, and the processor is for running program, wherein
Described program executes the minimizing technology of residual printing silk described in any of the above embodiments when running.
The beneficial effects of the present invention are:
1, the present invention is using the characteristic of melt flow stream and the effect of gravity, to remove remaining printing silk, fills molten chamber, it is ensured that weight
New printing rear nozzle will not flow out residual printing silk, scraps so as to avoid printout, improves product qualification rate.
2, the machinery of printer ensure that without configuring mechanical screeding device on a printer using method of the invention
Structure is simple, and not will increase cost.
