Lastly, if other un-meltable materials or dissimilar materials with higher melting temperature than
your plastic of choice enter your system, you may find over time that your nozzle becomes
clogged. Referring to Figure 4 (Nozzle parts), inside of the Nozzle Cap there is a breaker plate
and screen whose purposes are to aid in building stable pressure, and to act as a last line of
defense against contaminants entering your filament. In the event that your screen becomes
clogged, please contact ReDeTec support for assistance in how to clean your screen! This
process requires special care and safety when executing and a trained specialist will be happy
to advise.
3.3 Plastic Care: Dry vs Wet - Clean vs Dirty
Similar to filament, you want to make sure your plastic is dry and kept clean prior to use. All
plastic is inherently “hygroscopic”, meaning it readily absorbs moisture from the air into its
molecular structure. This moisture is your enemy when it comes to extrusion! Extruding with wet
plastic will cause the moisture to be vaporized during extrusion, causing bubbles in the output
and vastly changing the extrusion properties. In most cases this will prevent you from achieving
high quality consistent filament.
It is very important to follow a strict regimen of properly drying, and managing your dried
plastic before extrusion.
The drying process is simple and may be done using an oven, toaster oven, or food dehydrator.
If using an oven or toaster oven the moist air must be removed for proper drying. Plastic
manufacturers will give specific recommendations on drying temperatures and times.
Temperatures and times used for ABS and PLA are shown in Table 1.
Table 1 : Drying Guide for PLA and ABS.
Make sure your drying system is already preheated before starting the timer for the drying times
stated in Table 1.
After drying, the plastic must be immediately stored in an air-tight container or bag with
desiccants until use for extrusion, otherwise it will quickly reabsorb moisture from the air again.
Ground plastic will have had plenty of time exposed to the environment, and must always be
dried for best results.
