10 Common 3D Printer Issues in 2019

A list of common problems when 3D printing is not known to all 3D printing enthusiasts. Some people are lucky to experience no issues with their device. However, this strip of luck can suddenly break for no apparent reason.

Here are some of the top 3D printing issues with FDM technology:

  • Filament-related 3D printer issues
  • Blocked nozzle problem
  • Nozzle too close to the bed
  • 3D printing setup issues
  • 3D print failure
  • 3D print does not stick to the bed
  • Messy first layer issues
  • 3D print supports breaking
  • Other complications that require attention

3D Printing Troubleshooting Guide

Let us say you were excited to select a fantastic 3D printing model for beginners and began to craft it on your reasonably priced 3D printer. The project starts, you cannot wait to see the final result, but something goes wrong and your print fails.

Well, you can fix some of the most common 3D printer issues yourself. Follow the Gambody’s troubleshooting guide that reflects solutions to 10 problems 3D printing enthusiasts face the most.

1. No Filament Coming Out of Extruder

Some FDM printers display the filament reel, and you can see when you are out of filament. But some devices have these reels hidden. So, when no filament is coming out of the extruder, you start to believe that your 3D printer is broken.

Just in case, double-check your filament reel and load some fresh material if this is the case of your problem. The fix can be straightforward.

2. Nozzle Blocked 3D Printer

If you tried to insert new filament because your 3D printing project would not start, and nothing works, you might be facing blocked nozzle 3D printing issues.

It could be possible that you left a tiny piece of filament in your nozzle while replacing spools. Even a small piece can block the nozzle and prevent the new filament from extruding.

This common 3D printer issue often occurs when you are switching from ABS to PLA all the time. You can fix it by cleaning the nozzle with a needle. It is best to do when you heat the nozzle to correct temperature using your computer software. Make sure not to burn your figures, and check your troubleshooting guide from the manufacturer that comes with the device.

3. Nozzle Too Close to Bed

These are other common problems when 3D printing. Sometimes you have loaded your filament. You start the project and are happy to observe that your print head starts to move. But nothing comes out to the bed.

The issue can be with the nozzle which is too close to the bed. A short distance can block the way for melting filament and prevent it from extruding. Try to slightly move the position of your nozzle away from your bed, or lower the print bed a little bit. It can fix your problem.

4. 3D Printing Setup Issues

Let us say you are new to 3D printing and have just configured your device. You begin to make a cute cartoon character 3D printing model, for example, but hear a horrible noise and understand that something is not right. If you see that your print head gets to the side of your device and cannot produce a print, this 3D printing troubleshooting guide is for you.

Make sure you have chosen the current 3D printer from your dropdown list in slicer software. Double-check all your settings such as print volume (the printer has to understand its exact print platform). Make sure you are running the most recent firmware version. And if this is your first device, contact the manufacturer to be sure that there is no misconfiguration on their side.

5. Print Is Not Sticking to Bed

If you notice that your project is not sticking to your print bed, you can quickly fix this problem. It is a common issue when a model has little contact with a platform. If everything is fine with the project you are making, then the problem can be with the platform itself.

Firstly, the platform might be unleveled. You should make it even to solve these common issues. Or you must adjust your nozzle height to get rid of filament “spaghetti” bug. It is also possible to apply a layer of glue or other adhesion to the platform to help the print stick to the bed.

6. 3D Print Messy First Layer

One of the most common 3D printer issues experienced in 2019 is a problematic first layer or several layers of your print. It can happen for multiple reasons. Maybe the project cannot stick well to the platform, or the printing bed needs levelling. Or perhaps the problem is with the nozzle.

Anyways, you can fix the problem yourself in many situations. Try to level your bed manually if your device does not support auto levelling option.

If this does not help, lower down the temperature of the bed by a couple of degree increments. You will notice that once adhesion reaches the desired temperature, your project will nicely stick to the platform.

7. 3D Print Failed

You are about to turn your favourite Marvel villain 3D printing model into a figurine, but the extrusion suddenly stops, and your project is screwed. In case your 3D print failed, there are several things that can help you fix this unpleasant problem.

Firstly, you should be sure that there is enough filament to complete the project. Secondly, double-check that your nozzle is not clogged. Thirdly, reread the troubleshooting guide and instructions for your 3D printer device and search for fixes there.

8. 3D Print Gaps in Walls and Layers

Let us imagine that you are making an outstanding World of Warcraft 3D printing character, but your project is upset with an unpleasant gap between the walls and infill. Such holes in walls and layers are among the most common 3D printer issues when you have not set infill overlap feature in the slicing software.

You can fix the problem by adjusting the settings in the slicing program and increasing the value for the infill overlap to 25-35 per cent but keep it below 50 per cent.

Sometimes the issue can be fixed by starting to 3D print infill before your main shell is printed, or by working on lower print speeds.

9. 3D Print Edges Curling

You can sometimes notice how your model’s base (first layers) are curling upwards and do not level with your bed. It can lead to further cracks in the model, and it is usually caused by the difference in temperatures of a cooling plastic and cold platform.

If you wish to prevent 3D print edges from curling, it is best to pre-heat your bed beforehand. Set it to the temperature that is 1-2 points below the recommended by your filament company.

If you cannot fix the problem by playing with temperature settings, try to apply a layer of glue to your bed. When you reach a perfect adhesion, your project’s edges will stop to lift.

10. 3D Print Supports Breaking

When you wish to make complex 3D printing models like Halloween 2019 masks and costumes, you can experience issues with your supports felling apart. If a model that requires supports is left unsupported, it will not print correctly.

Make sure you are choosing supports according to the type of your 3D printing model. For projects with overhangs, it is better to select zig-zag or line supports. If your project has minor contact with the platform, go with triangles or grids. You can also apply additional adhesion for the supports to not break when 3D printing.

We hope that our list of 10 most common 3D printer issues and 3D printing troubleshooting guide are handy to you. These tips and tricks are meant to improve the quality of your figurines and statues, which you are welcome to post to Gambody Facebook Group.
