3 common 3D printing problems and solutions

Date of release:2018-11-12 Author: Click:


One day in the future, we hope that by pressing a button, a near-perfect 3D printed object will appear in front of us in a few hours. No fuss, no trouble. It sounds pretty good! Although 3D technology has been around for a long time, there is no such magic button at present, and every manufacturer has encountered this challenge for a while. But you are a creator, so you always have to figure out a way to solve the current problem.


      To help you find the solution faster, here are some common problems you may encounter, and you can fix them by adjusting them.

1. Drawing/consumable material seepage


     In the gap of printing, sometimes molten consumables ooze out from under the nozzle, and after being oozing, the nozzle is pulled to the next printed place, which causes the surrounding of the print to look like a layer of spider web, which we usually call " Drawing, this kind of wire drawing is difficult to remove.


Fallback setting: The reason for this phenomenon is that the slicing parameters of the slicing software are not set. Fortunately, this problem is easy to solve. Each slicing software has a program called "Retraction" that relieves nozzle pressure and prevents molten consumables from flowing out of the nozzle when the printer is not printing. This program prevents more consumables from being pulled from the nozzle to the next place where they were printed. As printing continues, the printer will re-feed the consumables to the nozzle. If the retraction setting is too high, the nozzle may be clogged when printing continues. So it may be necessary to do some testing based on the printer and consumables used.


      One thing to point out is that there is a difference in the back-off settings for the remote feeder and the process feeder. The length of the retraction setting determines how long the wire will be retracted from the inside of the nozzle. The remote feeder setting should be higher than the direct feeder because the remote feeder is more distant from the drive gear to the nozzle. long. For direct feeders, the setback value should be less than 2.5mm, and too much 2.5mm will cause nozzle clogging.


      The setting value of the remote feeder is recommended to be between 1 and 5 mm. If there is a problem of drawing, it is recommended to start the test from 5mm. Know the parameters that are most suitable for the printer and consumables. The speed of the retraction should be set at 30-45mm. between.


The speed of movement of the non-printing action nozzle: the slower the movement of the non-printing action, the longer the time the consumables flow out. Improve the running speed of the non-printing action of the nozzle, which can effectively prevent the drawing phenomenon during the printing process. After observing some tests of retreat and nozzle speed, and after a series of print tests, someone found the best setting to prevent the drawing of their printer. They found that the retraction speed of 150mm/s is the best setting for their printer, but different printer settings will be different, so it may be necessary to try several times around this value.


Adjust nozzle print temperature: When the print temperature of the nozzle is too high, the consumables are easy to draw. Confirm the recommended printing temperature of the printing consumables of the material (the temperature of ABS and PLA is very different), reduce the temperature by 5-10 °C based on the recommended printing temperature, and observe at which temperature the best printing results.
