Application of PEEK filaments in 3D printing
Now that I have an understanding of PEEK and PEI, I may want to do PEEK printing myself.
When using PEEK or PEI for 3D printing, please remember the following basic techniques
The temperature is consistent.
PEEK/PEI exhibits poor response at fluctuating or unstable temperatures. Therefore, if not necessary, it is strongly recommended to use a printer in a closed room. To achieve good results in 3D printing PEK/PEI, it is recommended to keep the 3D printer in an environment with temperature changes, away from solar radiation and frequently visited places.
Be careful of black spots
Users may encounter black spots when printing with PEEK/PEI. There may be many reasons for this, but a common explanation is impurities in the printing materials used and the 3D printer's inability to handle the required temperature.
Keep the nozzle clean
After the printing process is completed, the nozzle should always be cleaned. All residual materials must be removed from the nozzle. Otherwise, it may clog and eventually cause black spots (as mentioned above).
Pay attention to crystallization
Incorrect crystallization may occur when printing with PEEK/PEI materials. If some of the colors in the printed part are different, such as opposite to the default beige color, it is brown, which may indicate incorrect crystallization. This may be caused by temperature fluctuations during the printing process.
Store materials in a dry place
When not using PEEK/PEI for 3D printing, the material should be placed in a bag and stored in a cool, dry, and dark place until it is ready to be used again. This can preserve the quality of the material and ensure the results.
