When using silk PLA as a special material for 3D printing, you may encounter the problem that the interlayer bonding is not strong enough, which may cause the structure of the printed object to weaken or break easily. The following are some ways to solve the problem of weak adhesion between layers of silk PLA:
Increase the printing temperature: Increasing the nozzle temperature can help the silk PLA layer to better bond. Appropriately increasing the printing temperature can increase the melting degree of the material and help the layer to fuse with each other.
Adjust the layer height: Reducing the layer height can increase the bonding area between each layer, thereby improving the strength of the interlayer bonding. Smaller layers usually produce better interlayer bonding.
Use slower print speeds: Reducing print speeds makes it easier for thermoplastic materials to fuse between layers, thereby increasing the bond strength between layers.
Increase the filling density: Increasing the filling density can increase the support structure inside the printed object, helping to improve the strength of the overall structure and the firmness of the interlayer bonding.
Try different print Settings: Depending on the actual situation, try adjusting other parameters such as cooling fan speed, nozzle flow, etc., to find the best printing setting for silk PLA.
By trying the above methods and gradually adjusting the printing parameters, the problem of weak adhesion between layers of silk PLA can be improved, so as to obtain a more robust structure of the printed object.
