BIOWA Olive 90A Filament

Drying (Essential)

Properly dried filament is crucial for achieving high-quality printing results.

• Temperature: 50 - 55 °C  
• Time: minimum 1 hour
• Recommendation: After drying, store the filament in a sealed dry box or humidity-controlled container to prevent moisture absorption.

Idler tension

• To prevent the filament from folding or buckling in the extruder, loosen the idler screws to the bear minimum. The filament should slip if it is not being fed through the nozzle.
• It’s best to fine-tune the idler tension while performing a test print. Start with the loosest setting possible and tighten gradually if necessary.

Filament sensor

• Due to the reduced tension from the idler adjustment, it may be necessary to bypass or adapt the filament sensor to prevent filament stretching or underfeeding during printing.

Spool holder

• Use a ball-bearing spool holder so the spool rotates freely. Preferably mount the spool inside a dry box with a bearing holder to keep the filament dry and minimise feed resistance.

Filament tube

• Use PTFE tubing for the filament path to reduce friction and smooth feeding.

Nozzle Diameter

Due to the organic fillers in our filament, we recommend to use nozzle diameters from ≥0.6mm to prevent clogging.

Print Speed = Volumetric Speed ÷ (Line Width × Layer Height)

Unlike standard filaments, flexible filaments tend to stretch during extrusion, producing thinner lines than expected. As a result, the actual line width will often be slightly smaller than the nozzle diameter.

Print

• Recommended print speed: 15–25 mm/s for optimal quality. After slicing, check both the Print Speed and Volumetric Speed values.
• Because of the looser idler screw tension, retraction settings should be reduced, both in distance and speed, compared to default values.
• To compensate for the reduced retraction, increase the travel speed, particularly along the Z-axis, within the printer’s mechanical limits, to help minimize stringing.

Retraction Settings

Nozzle Temperature

• First Layer: 165 °C
• Other Layers: 160 °C

Bed Temperature

• 60–70 °C
• Use an adhesive to improve print bet adhesion

• General: 0 % (fan off)
• First layer: 0 %
• For bridging: 80% fan speed

BIOWA Olive 90A Filament adheres best when the first layer is printed without cooling.

• Keep filament dry before and during printing.
• Always store BIOWA Olive 90A in a sealed dry box when not in use.
• Avoid sharp filament paths to prevent bending or compression during feeding.
• Regularly check the extruder gears for residue or buildup from flexible materials.
• Use a Direct Drive Extruder for optimal control.
• Print multiple small parts at once to improve layer cooling.
• Regularly document and refine parameters for consistent results.
