6 Common 3D Printing Problems and How to Fix Them
3D printing is a creative technology that has brought a lot of advancement and convenience to the world in general. A lot of products, figures, building and letter models can now be printed for various uses including home uses and architectural analysis. When we talk about home usable, a lot of pieces and wholes that can be used in the home are now available in 3D prints. This saves one the money that would have been used to purchase them. When we also consider the architectural world, a lot of creative structure models can now be printed using 3D printers. This makes the architectural analysis easier.
Generally, 3D printing has brought a lot of convenience in living and creativity in work. But there are some common downsides to this technology - just like any other technology. Whether it is commercial 3D printing you are into or you use 3D printing for your personal and private purposes, you would most likely have experienced one printing problem or the other. This informational content is here to thoroughly examine common 3D printing problems and give profound solutions to them. So, enough of being pushed into a tight corner by your 3D printing problems, this content would examine six common problems and how to fix them. Relax and learn how to solve those nagging printing problems.
- 3D printer overheating: 3D printers work by using heat to melt the printing filament inside them to form layers of plastic which would eventually form a whole 3D model. This heating requires a high temperature, and not all 3D printers have anti-heat technology. Even if your printer has such, there is every possibility that the printer would overheat in the long run. When your 3D printer overheats, it brings along with it a host of other printing problems. Your 3D models would have distorted shapes and wobbles. In the long run, your 3D printer would most likely breakdown.
How then can you fix this overheating problem? There are two profound solutions to this problem. The first thing you should do if your 3D printer overheats is to slow down the printing speed. The fact is that a higher printing speed reduces the time it takes for your 3D printer to print a 3D model. So, most times, we prefer to print many models within a short period. But the faster the speed at which your 3D printer works, the hotter its components get. To reduce overheat to its barest minimum, slow down your printing speed. This way, each layer of plastic cools down before another layer is formed and heat is greatly reduced.
Another solution to this problem is to check your 3D printer fan. Every 3D printer has an inbuilt fan to cool the printer components while printing. If the fan of your 3D printer is faulty, there is a very high risk of overheating. So, make sure the fan is in good working condition and you are good to go.
- Clogged filament nozzle: This printing problem is common to commercial 3D printing. Why is this so? In commercial 3D printing, a lot of 3D models are printed daily; different sizes and shapes. As a result of the quantities of models printed, a lot of particles and fossils are very likely to block the nozzle of the 3D printer. This printing problem is characterized by noise emanating from your 3D printer. The noise would sound like clicking or grinding noise.
NOTE: This problem is not impossible in private 3D printing, it is just that it is common in commercial 3D printing.
How then can you fix this clogged filament nozzle problem? First, you simply remove the particles and plastic clogging the nozzles. How do you do this? Use a tiny rod to push out the particles and plastic. If the particles are very dense, you can simply loosen the nozzle as a whole to remove all plastic and particle clogs. This would work better for dense particles.
Another solution is to replace the particular PLA, PETG or ABS filament you are using. While printing, allow your filament extrude to cool down and reheat before using it again. When the filament material gets too hot, it can flow into the heat break area, thereby leading to a breakdown of your 3D printer. Now you know the amount of good a cool 3D printer and its components can do you in 3D printing.
- Empty spaces on 3D prints: This is a very common problem in 3D printing characterized by distorts in the form of unfinished details and structuring of your 3D models. You see, while printing, the plastic layers need time to simmer down to be sturdy. More so, your 3D printer needs time to absorb the UV light to print out the details of your 3D models correctly. But when your printer prints too fast, there is not enough time for the plastic layers to cool down. Also, there is not enough time for your 3D printer to absorb the UV light for model details. All these would then lead to the omission of details; some parts would not be printed (unfinished printing).
How do you fix this? What you need to do is to use the recommended 3D printer acceleration settings. Set your printer acceleration to 1500mm/s2 and the speed to 60mm/s. This would help regulate the overall printing speed of your 3D printer.
Another fix is to check the resin temperature of your 3D printer. This could improve the strength and sturdiness of your 3D prints. Also, you could increase the general infill of your filaments for your 3D printer to be able to fill in all the details of your model(s).
- Your 3D models are sticking to your printing bed. This is another frequently-encountered 3D printing problem that can be very frustrating. This problem is characterized by your prints refusing to come off the printing bed.
How do you fix this problem? The first thing you should do is to wait for the 3D print(s) to cool off and give off some heat. By the time the print cools down, it should come off the printing bed. But if after letting time pass and your print is still stuck to the printing bed, you would then have to try another fix.
Another thing you can do is to use a palette knife to gently remove the 3D print from the surface of the printing bed. This solution is a little bit crude and can damage your 3D print. So, to avoid this, you should regularly clean the surface of your printing bed to remove glues and sticky particles. This way, your 3D print(s) would rarely stick to the printing bed.
- Printing filament residue on your 3D prints. This problem is a finishing problem in 3D printing. It is usually referred to as “stringing.” This problem is characterized by your 3D prints having strands of glue attached to them after printing. It is usually caused by excess filament pushed through the printer nozzles which then stick to your 3D prints.
How do you fix this problem? Filament strings make your 3D prints look distorted, more so, they are difficult to remove. The solution is to avoid them. To avoid strings on your 3D models, reduce the heat settings of your 3D printer. Also, adjust the printer's retractor for standard and tidy printing. When you do this, your 3D prints would not only be free of filament strings, they would also be neatly detailed.
- Distorted print layers. This problem is characterized by the layers of your 3D prints not adhering to each other. When this occurs, the whole 3D model looks warped and distorted. In essence, the shaping and detailing of your 3D print is distorted. What is the main cause of this problem? The main cause of this problem is the warping of the bottom layer. When this happens, other layers that form the whole print would not adhere to each other properly.
How do you fix distorted print layers? The problem is quite easy to fix. All you just need to do is to adjust your printing plate temperature so that the layers would form quickly without waiting to disperse heat. This way, the layers would not contract due to cooling which makes layer adhesion difficult.
Another thing you can do is to improve your plate leveling. When your build plate is well leveled, layer adhesion is more effective. How can you level your printer plate? All you need to do is to regulate the distance between the nozzle and the build plate. You should set the distance to standard. Also, make sure the calibration is not too tight to make the filament extrude work correctly.
