Poor Layer Adhesion Problem: Weak layer adhesion results in layers separating or delaminating during or after printing. Solution: Increase the nozzle temperature to ensure better inter-layer bonding. Slowing down print speed can also improve layer adhesion. Make sure the cooling fan is not set too ...
I usually print PET at: nozzle 215...225°C, bed 90°C, speed 25...30mm/s, layers 0.06...0.20mm thick, and no cooling if there are no overhangs and bridges. If bridges/overhangs, then a little bit of fan is needed, but that reduces layer bonding. And yes, expect more stringing...
PETG sheet PETG is called low temperature PET, it's a new environment-friendly packing material with features such as high luster, good transparency, excellent barrier property, self-adhesion, which is used for glue bonding and high-frequency processing.CPET sheet CP...
The ambient temperature definition for the first layer of the wall was set to 74.5 °C to approximate the air temperature near the heated bed, while the ambient temperature for the remaining layers was set to 40 °C, which is approximately the value measured by embedded thermocouples after ...
The deposited copper acted as seed layers for further adsorption of copper ions, and the procedure was repeated. Then, for accuracy, the specimens were tested under a microscope to determine whether the copper was properly deposited on the surface or not. The entire copper deposition process is ...
As previously pointed out, for deposition angles between 10 and 30° to the transversal direction, both ultimate stress and strain increased due to the simultaneous augmentation of both the number of adjacent layers that were simultaneously deformed and their bonding area. However, at 40° ultimate...
industries. However, there are still challenges and unknowns that are inherited by this technology. For example, the material properties of 3D-printed parts are not any more equal to bulk material properties since the bonding strength of the layers dominates the material properties of the actual ...
Another piece of evidence from this study reveals that temperature proved to be a very important parameter because it influences the fluidity of the extruded filament, its solidification characteristics and consequent inter-bonding strength between layers. Therefore, when carbon fibres are added to the ...
It was deduced from previous graphs that the highest amount of liquid for all solutions happened in the very first days, probably because the liquid rapidly flowed inside the specimens through all the defects, micro holes, and the bonding defects of the external layers. In addition, it is inte...
Significant advances in fused deposition modeling (FDM), as well as its myriad applications, have led to its growing prominence among additive manufacturing (AM) technologies. When the technology was first developed, it was used for rapid prototyping to
