Common 3D Printing Problems And How To Fix Them

3D printing guarantees pinpoint precision and precision. It allows mass customization and offers you the ability to deal with almost all levels of complexity. Through this technology, we can plainly say that we are only limited by imagination. Although the printing technology is remarkable, it ships with its impartial share of negatives. The following are the most common 3D printing hitches and procedures of fixing them:

Stringing

One must have come across this problem If they have been using printing machine for quite some time. Stringing occurs when you have minute little hairs in between your print gaps.

This results when some filament leaks from the nozzle as the print moves above an open part.

To fix this, enable retraction. It is a feature of the printing software. Enabling retraction causes the printer to retract the filament in the nozzle prior to the travel moving. This guarantees that no excess plastic drips from the nozzle hence producing strings.

Warping

Warping is a problem which occurs when one or more printing machine’s corners lifts up till the model’s base is no longer at the same level with the print board. This eventually results to eruption of horizontal cracks on the upper parts of the printer machine.

The problem occurs when the plastic of the primary layers of your printer cool down thus starting to shrink.

In order to fix this problem, you need to ascertain the cause of the issue. One way of fixing the problem is to heat the platform so as to keep the plastic inside at a temperature below the point it solidifies. This ensures the prints adheres to the bed.

The other way of fixing the problem is placing an additional thin layer of glue to the platform is using rafts which give the printer a larger surface area at the base.

Cracks

This problem is common on tall and thin models. The gaps cracks are found on the model’s sides. The great thing with the problem is that it is simple to fix. You just need to raise the extruder temperature in 10-degree increments. In case, this trick does not work, then increase the temperature of the bed by 5-15 degrees.

Under Extrusion

This occurs when the printer stops supplying the required material as fast as it is wanted. This results in thin layers.

The problem is caused by many factors like the failure of the filament’s diameter to match the diameter that is set in the slicing software, the presence of dirt on the nozzle and faulty settings of the slicer software.

A way to fix the problem is making sure that the filament diameter suits the one in the slicing software. You also ought to check the nozzle and get rid of any dirt that may be there.

Elephant Foot

The model’s base is slightly bulging outwards. This is otherwise known as the “elephant foot.”

This awkward effect can also be brought about by the model’s weight pressing down the first layers when the lower layers have not had enough time to cool and solidifies especially when your printer has a heated bed.

It is tricky to find the correct balance between avoiding the elephant foot effect and getting rid of warping. To reduce bulges at the base of the model, it is recommended leveling the printer bed as well as moving the nozzle a bit far from the bed but not too far. Otherwise, the print will not stick. Additionally, slightly lower the bed temperature.

If you have created the 3D model by yourself, place a small chamfer at the bottom part of the model. Begin with a 5mm and 45º chamfer, and experiment to get the best result.

More First Layer Problems

Here, the first layer hasn’t stick properly. Hence, some parts are loose.

These 3D printing predicaments are typical indications that the print bed has not been leveled correctly. If the nozzle is too far from the bed, then the bottom surface usually shows undesired lines, and/or the first layer doesn’t stick. In case the nozzle is too close on the other hand, blobs may be the as a result.

Also essential to note is that the print bed ought to be as clean as possible. The fingerprints on the plate may prevent the first layer from adhering to the plate.

To correct this, re-level the print bed using the printer software, clean off the fingerprints from the bed and finally, apply a fine film of glue prior to printing
