PLA Filament Flashforge PTBL2 1.75mm Transparent Blue 0.5kg spool

Flashforge PLA filament PTBL2 in transparent blue is a 1.75 mm diameter filament supplied on a 0.5 kg spool for FDM 3D printers that accept PLA. The material offers the standard properties of polylactic acid: ease of printing, low warping, and a smooth surface finish suited to prototypes, visual models and hobby prints. The transparent blue colour provides partial light transmission for decorative parts or layered effects while maintaining dimensional stability under normal printing conditions.

Advantages

The filament is formulated for reliable extrusion on printers calibrated for PLA and delivers consistent diameter and layer adhesion to reduce print failures. Its transparent blue appearance enables aesthetic parts with subtle translucency and clean surface details. Printability characteristics include low odor during extrusion and minimal shrinkage, which helps maintain dimensional accuracy on medium-sized prints.

Suitable for

• Rapid prototyping and concept models
• Decorative and display items with translucent colour effects
• Hobbyist prints, miniatures and figurines
• Functional non-load-bearing parts and jigs
• Educational projects and classroom use

Key specifications

• Material: Polylactic acid (PLA)
• Diameter: 1.75 mm
• Spool weight: 0.5 kg
• Colour: Transparent blue
• Compatibility: FDM/FFF 3D printers that accept PLA filament
• Recommended print bed: unheated or mildly heated (depending on adhesion method)

How to use

Load the filament into a 3D printer configured for 1.75 mm PLA filament. Set the nozzle temperature according to your printer and PLA manufacturer's recommendations; typical nozzle temperatures for PLA range from 190–220 °C. Use a print speed and layer height appropriate for the nozzle diameter and model detail; calibrate extrusion multiplier if necessary to ensure dimensional accuracy. For bed adhesion, use blue painter's tape, a PEI sheet, glue stick, or a mildly heated bed set to the temperature recommended by your printer documentation. Allow printed parts to cool before removal to maintain surface quality.

Usage recommendations

Store the spool in a dry environment and keep it sealed or in a desiccant-equipped container when not in use to prevent moisture uptake. For best optical effect, print with thinner layers and moderate infill to enhance translucency. Avoid exposing finished parts to prolonged UV or high-temperature environments to reduce the risk of colour fading or deformation.
