4. Preparing for Printing
- Ensure proper bed adhesion using a PEI sheet or PVP glue coating to prevent warping.
- Use an enclosure to maintain consistent temperature and reduce potential warping, especially for larger prints.
- Implement proper cooling strategies, adjusting fan speed based on part geometry and size.
- For complex geometries, consider using soluble support materials compatible with high-temperature printing.
- Post-processing may include annealing to further enhance mechanical properties and heat resistance.
- Always handle the printed parts with care, as they may have sharp edges or be hot immediately after printing.
- Annealing is not recommended given it can warp the print.
