When the process of printing 3D objects, we will get a 3D Print Quality Problem. For those of you who are still beginners in operating a 3D Printer, maybe you will be a little confused.
In this article I will share my experience so far that I have had problems with the print object that I did.
This post is my experience with the most common quality problems with 3D printers.
This is because the extrude filament temperature is too low or the nozzle fan is too tight, so that the first layer and the other layer are not attached tightly.
To fix this, we have to adjust the temperature, according to the type of material used. To see the standard temperature of each material you can see here.
If you use ABS or PC (Polycarbonate) materials, I suggest you to make the fan rotate a maximum of 20% only, so that the filament adheres perfectly.
Blobs are lumps of filament that come out more. This is due to the start point process. The start point is the beginning of the nozzle to move the filament to make 1 layer.
For better results, we must determine this starting point.
If you use Cura software, you can activate Seam in Walls profile. Set to user Specified and first print set to X & Y to 0. Look at the following picture:
Similar to blobs, but slightly different. Lumps that look not the same, there are long and short.
This usually happens for two reasons:
- Nozzle too hot
- Retraction value too high
If the filament is too hot, it will melt faster. Although the object to be generated is more attached between the layers, there will be Nits. To control it, make sure you set the appropriate material temperature.
If the retraction value is too high, allowing the filament not to be pulled completely into the nozzle, this will probably leave the filament in the nozzle. When the retraction is lowered, then there are more files that appear out.
Improve material temperature or retraction value.
For now, this is all I can share. Of course there are still many 3D Print Quality Problem that have not been explained.
