3D printing ensures pinpoint accuracy, enables mass customization and gives you the ability of handling almost any level of complexity. With this technology we can literally say that you are limited by your imagination. While the printing technology is awesome, it comes with its fair share of negatives. Here are 4 common 3D printing problems and how to fix them:
Warping is when one or more corners of your printing machine lift up until the base of the model is no longer at level with the print platform. This results to horizontal cracks in the upper parts of your machine.
The problem comes about when the plastic of the first layers of your machine cool down thus start shrinking.
To fix the problem you need to identify the cause of the problem. One of the ways of fixing the problem is heating the platform in order to keep the plastic at a temperature that is below the point where it solidifies. This keeps the prints adhered to the bed.
Another way of fixing the problem is adding a thin layer of glue to your platform. There are many ways in which you can do it. One of the most effective ways is using rafts which give the print a larger surface area at the base.
If you have been using your printing machine for long you must have come across this problem. Stringing happens when you have tiny little hairs between the gaps of your print.
The problem results when some filament drips from the nozzle when the print moves over an open part.
Stringing is a problem that fixable. One of the ways of fixing it is enabling retraction. Retraction is a feature on your printing software. When you enable retraction the printer retracts the filament in the nozzle before the travel moves. This ensures that no surplus plastic drips from the nozzle thus producing strings.
Cracks are common on tall, thin models. The cracks and gaps are found in the sides of the model. The cool thing with the problem is that it’s easy to fix. One of the things that you need to do is increase the extruder temperature in 10 degree increments. If this trick doesn’t work increase the bed temperature by 5-15 degrees.
Under extrusion is when the printer fails supplying the needed material as fast as it’s required. This results to thin layers.
The problem is brought about by many factors such as: failure of the diameter of the filament to match the diameter set in the slicing software, faulty slicer software settings and presence of dirt in the nozzle.
One way of fixing the problem is ensuring that the filament diameter matches the one set in the slicing software. You should also check the nozzle and remove any dirt that might be there.
