    General safety (FusRock)

    1. For intensive long-term 3D printing, use a dedicated room with adequate ventilation.
    2. If you have allergies, confirm the materials you use do not trigger a reaction.
    3. Wear a mask if you have chronic respiratory conditions; others are strongly advised to wear a mask during operation.
    4. When sanding or cutting fiber-reinforced parts, use proper PPE to avoid skin contact or inhalation.
    5. Keep printing away from children and infants.

    Spool routing & moisture control while printing

    How to route filament

    Recommended

    Use a diagram like your internal “correct feeding layout” poster (replace with image in backend):

    [Image: correct feeding path — bearing-equipped dry box + PTFE tube to the extruder]

    Use with a dry box and ensure snag-free feeding. Prefer a bearing-supported dry box and route through PTFE tubing into the hotend.

    Not recommended

    Do not casually “hang” moisture-sensitive filament outside the printer (absorbed moisture can cause stringing, failed prints or poor cosmetics).

    If you must hang a spool, check whether brackets or sheet-metal tabs interfere with the spool flange, causing extrusion drag or jams. (Add your solution link or note below.)

    [Image: tab contacting spool flange]

    Example: machine tab rubbing against spool flange

    Moisture control
    1. Refresh desiccant on schedule so the filament is not silently saturating while the hygrometer barely moves.
    2. During printing keep filament in a proper dry box. Avoid heated “dry boxes” marketed for use while actively printing if they bake the spool unevenly—they can worsen aging and trap moisture inside.
    3. When printing from AMS / AMS 2, monitor humidity badges/indicators and replace desiccant as needed.
    4. If filament picks up moisture, dry it promptly (see the Moisture treatment & storage tab).

    Storage (moisture protection)

    Short breaks Store in a sealed dry box or apply a simple vacuum pack; avoid direct sunlight.
    Long-term storage Return filament to the factory foil bag, squeeze out air (add a fresh desiccant pack if available), then place inside a household vacuum bag and pull vacuum. Keep in a cool, dry place away from sunlight.
    Drying damp filament — guidelines
    Drying parameters

    PTC compact dryer box: 60–70 °C for 4–6 hours.

    Small lab oven (forced-air): temperature uniformity is often limited; spools can warp. Reduce temperature/time (example: 40–45 °C for ~4 hours) and cross-check the material-specific drying notes in the datasheet.

    Important: if print quality does not improve, test with an empty spool before raising temperature—non-uniform heat can deform plastic flanges.

    Large forced-air oven: 60–70 °C for 4–6 hours.

    PS: Why do devices differ? Add an internal article or external link (“learn more”).

    Precautions

    Read before drying

    1. When in doubt, run an empty-spool temperature trial before increasing heat.
    2. Follow the recommended temperatures/times from the product / material admin page.
    3. Prefer forced-air ovens; do not blast the spool directly with hot air.
    4. Avoid exposing the spool edge to a violent air jet.
    5. Do not rest spools only on wire racks—use a flat heat-spreading plate if needed.
    6. Hot spools can burn—use gloves.
    7. Observe fire and electrical safety.
    8. Avoid microwave ovens or other uneven heaters; a temperature-controlled drying oven is preferred.

    Dry vs damp

    What moisture does to prints

    DryDamp
    Cleaner surface, stable color, mechanical properties on specPitting, stringing, whitening, weaker properties (material dependent)

    (Optional: 1 / 2 / 3 day exposure at ~80% RH — same test part.)

    * Example photos may reference a specific grade (e.g. PAHT-CF); label yours accordingly.
