By leveling your bed, you also place a mouthpiece away from the bed. This distance should correspond to the height of your first layer and the amount of plastic actually extruded when printing your first layer. If your Camping printer does not extrude enough plastic to fill the distance between the mouthpiece and the bed, you will have adhesion problems. Too much, or over-extrusion, and you have too much filament that has to go somewhere.
If this inner tube is used or broken down (occurs if it is printed too hot, usually above 260 ° C), the friction increases and the extruder can be too much step-by-step to overcome it. Recalibrate the step / mm value of your extruder to ensure that your extruder delivers the correct amount of filament requested. Once the steps per mm are properly configured, the next step for proper calibration is to correctly configure your extrusion multiplier to combat 3D extrusion printing. Many manipulators increase the fear of their drivers step by step, often unnecessarily. In addition, when high temperature filaments are printed in a closed or heated construction chamber, the vapors tend to heat up significantly.
In this tutorial we’re going to talk about self-cutting surfaces, missing triangles that create holes in the surface of your mesh, backward triangles and even double surfaces. But first let’s talk about the signs you can see if your mesh contains errors. In teflon-lined hottes it is necessary to change this part, usually every hundreds of hours. The Teflon or PTFE coating is a small tube located in the hot zone of the hot end to conduct the filament in the last centimeter of the race and breaking down by the temperature it reaches. Changing is a task that you need to learn how to properly maintain your printer. Within this range, the lower values will give us a better aesthetic appearance, as the deposit will be “cleaner”.
Flexible filaments are difficult to print with most extruders, as they tend to escape the intended filament path and just get stuck. Try to print much slower, try to print hotter and maybe even consider upgrading to another extruder design that specializes in flexible filament printing. But do not exceed the maximum recommended print temperature for the filament you use to prevent the filament from deteriorating on HotEnd, which can cause obstacles.
You can get a 3D pen to fill in the holes and holes you see after the printing process. Clean the surface of loose particles and make sure that the 3D pin materials and printer parts are the same before using the pen. Not everyone has 3D modeling skills or the time to renovate a broken part, let alone a 3D printer. 3D Hubs is a platform where you as a person can get 3D-printed stuff from someone in your area. Depending on how big the piece is and how cheap the Hub is, for example for this dishwasher clip, I would pay 5 euros.
Look for the glass transition temperature of the material you are printing. Make sure your bed temperature is at least about 10 ° C below the glass transition temperature. If your bed is well below the glass transition temperature and you are struggling to take out your printout, increase your bed temperature by 5 ° C until the problem is resolved . Many problems with the first layer of 3D printing are caused by the incorrect printing temperature during the first layer, because this directly affects the adhesion on the construction plate. Stay within the range proposed by manufacturers, at least about 10 ° C below the glass transition temperature. If you have problems with brittle 3D prints, you can increase the mouthpiece temperature.
The degeneration process of the PLA strands can take months, but some conditions can further aggravate the flexibility of the material. A common circulation theory is the adsorption of fluid through the filament. When placed in a humid environment, the filament absorbs moisture from the air and changes its physical properties. A brittle PLA strand results in broken parts that reduce texture resistance and cause uneven extrusion during the printing process. “There is a clear environmental benefit because you don’t have to sync new material every time it breaks.”. We extend the life of these materials, reducing plastic waste.”
