Storage & Preparation
Z-NYLON is highly hydroscopic and shouldn’t be stored without protection in humid
environments for a long time. Unused spools have to be stored in an airtight container
with a moisture absorber. Otherwise, the filament will absorb moisture from air which can
cause problems such as stringing or low surface quality of printed parts. Also, the color
of the filament can fade or become dull.
To remove moisture from the filament, perform a drying procedure at 90 °C [194 °F] for
2 hours.

Hardware Requirements
To create the best printing environment for Z-NYLON, it is best to equip your printer with
a separate hotend and a perforated plate that will be dedicated only for printing with this
material. These parts should be new and not used with other materials.
Also, avoid using adhesive substances with the new perforated plate.

Model Preparation Tips
As all nylon-based materials, Z-NYLON is highly prone to warping. That’s why, while
preparing your model in Z-SUITE, go to Advanced section in the Print settings step and
set the Fan speed to 0%.
If you’re preparing several small models for printing, make sure to separate them in the
workspace so that each item has its own raft structure. This way, a smaller printing area
can reduce the risk of warping.

Printing Process Requirements
While printing with Z-NYLON, it is recommended to provide proper conditions in the print
room. First of all, make sure that there are no draughts in your work area. Strong
airflows cause warping and may damage your print. Also, avoid printing in humid
conditions. Due to its high shrinkage, Z-NYLON is not recommended for printing large
geometric models with steep slopes in the Z axis. In general, models with walls that are
perpendicular to the platform will be less prone to warping. Still, it is advisable to add
support structures to all angles and overhanging parts of your model.
To reduce shrinkage, it is advisable to create a printing chamber with the use of Side
Covers and a HEPA Cover. These accessories have been designed to support the
printing process with materials of a high shrinkage rate.
Lastly, remove any residues of material extruded during the pre-print calibration. This will
facilitate adhesion of raft and the whole model to the perforated plate.
