Only for PA6 Xstrand you will need to place the material into an oven at 80-90°C for a few hours. A good way to test if the moisture ha been removed from the material is to bend the filament with your hands. If the material bends rather than breaks then allow more time in the oven. Dried material will snap when you try to bend.
XSTRAND GF30-PP have a high resistance to cracking, acids, organic solvents. GF30-PA6 is chemically resistant to oils and fuels, gasoline, mineral spirits, and some alcohols.
Recommended print temperatures for the Ultimaker can be found in the Cura settings. If you are using a printer other than Ultimaker the general rule is to print the PA6 Xstrand close to the default nylon settings as a good start (230-260°C) and for PP Xstrand use the default settings close to ABS. A heated chamber does help out with extremely large parts.
