If your 3D printing machine has given up on you, there is no need to wait up for the experts to help you. Here are some of the practical solutions you can try if your 3D printer encounters overheating, stringing, and layers that refuse to attach.
When Layers Fail to Attach
After everything was all set up right, the output of your 3D printer is not attaching itself properly to the surface you are wanting it printed on. This, by far, is one of the most complained about issues users have about 3D printing.
There could be several underlying reasons why 3d printing will fail this way, but for the most part of it, it is possible that your 3D printer is not at all leveled. This can bring about initial issues when it comes to adhesion but it is likely to warp your printed object.
You can start initial troubleshooting by adjusting your bed temperature. Keep it high enough so as to keep the plastic from curling and cooling down. This is the natural tendency for this type of material when contracting. You may try to set the temperature a notch high if you are still not happy with the results.
Secondly, see to it that your Z-axis or vertical is positioned at the correct height. This should be somewhere between 0.25mm to 0.10mm. Observing the proper height of the printing machine here is important, otherwise, it will not produce the right amount of pressure between the bed and the nozzle while trying to print out that vital first layer.
And then lastly, see to it that the printing bed is clear and clean from debris. It should be free from grease or anything that will keep the plastic from adhering properly to it.
Stringing is another all-too-common problem complained about 3D printing. This issue involves cobweb-like plastic strands and they randomly spread across or all over the object that you are trying to print.
This is likely to happen if the filament is leaking out from the nozzle, and gets itself caught up on the object. Trying to eliminate these cobwebs won’t be easy. Eventually, you will end up reprinting the object all over again, which can be a big waste of your resources.
Try to slightly lower the heating temperature, this should help in minimizing stringing. Don’t try to do it in a snap, but do it slowly — change the heat settings little by little, bit by bit and see what happens next. If this measure fails to resolve the problem, consider trying your printer retraction settings. Such values would pull the extra plastic back up, and move it away from the object you are trying to print, thus solving the issue once and for all.
Overheated 3D Printing Machine
Finally, we’ll tackle about overheating on 3D printers. This kind of issue can be disastrous to this type of 3d printing machines. Most of the time it will lead to wrongly shaped objects, warping them in the process. This occurrence is likely to happen if the working layers become smaller in size, such as when you are trying to print, say, a tower for example.
So far, the best workaround in this kind of issue is to just allow each layer to cool down. Perhaps, your printer has its own built-in fan already, but it will work to your advantage to invest in another one just so it will cool down faster.
The best way to combat this problem is to cool each layer. Your printer is probably equipped with a fan already, but there’s no harm in investing in another one to make cooling even quicker and more effective.
Most of the time, amateurs and beginners don’t possess the necessary skills needed in setting up their 3D printing machine.
But when it comes to the industrial printing machines, they usually come with exorbitant tag price, built to endure and last, and will have an expert team or staff whose main role is to set the system up for you and maintain them afterward.
Beginners and new users should really learn how to avoid these hurdles, but if nothing from these suggested troubleshooting steps works, then it may be high time to reach out to the experts.
