Handling/Storing Materials

Stratasys FDM thermoplastic materials will maintain proper product performance over an
extended period of time, when handled and stored according to recommended procedures.
Like other thermoplastics, the filament can absorb moisture when exposed to ambient
humidity. Stratasys material coil boxes are designed to minimize moisture exposure while
unopened and opened. When a filament absorbs moisture a finished part's surface quality,
seam quality, and overall part aesthetics can be affected. Care should be taken to ensure
filament remains dry.
The model and support material coil boxes hold 200 in
Material coil boxes also contain desiccant material; the desiccant is designed to maintain
proper moisture levels within the material coil box. Once the desiccant is exposed to ambient
air, it can become saturated and ineffective for moisture control. Proper handling of the material
coil box is essential to maximizing material life.
Head Replacement
When a head reaches the 1500 build hours odometer limit, a warning will be displayed on the
User Interface and the head's Head Status Icon will be highlighted in red on the Materials page.
You can continue using a head which has exceeded its odometer limit, but it is highly
recommended that you change the head as part quality will be unpredictable.

Replacing a Head

The information within this section is meant to guide you through the process of changing a
head. Although the instructions below depict the replacement of the model head, the same
procedure applies to the support head.
Empty material coil boxes may have a small, unusable volume of material
remaining. The leftover material allows for manufacturing tolerances.
Caution:
Material storage shall be in the range of 55°F to 86°F (13°C to 30°C), with relative
humidity less than 70%.
