Filament Prusa PLA 1.75 mm 1 kg — Prusa Oh My Gold (blend)

Prusa PLA 1.75 mm 1 kg — Oh My Gold (blend) is a 1.75 mm diameter PLA filament supplied on a 1 kg spool. Formulated for FDM/FFF 3D printers, this Prusa-branded PLA delivers predictable extrusion, low warping and little odor during printing. The Oh My Gold blend provides a metallic-like gold appearance suitable for decorative parts, scale models and visual prototypes where surface finish and color effect are important. The filament is compatible with any printer that accepts 1.75 mm PLA filament and can be used for a wide range of hobby and light engineering applications.

Advantages

The filament offers consistent diameter and roundness for steady feeding and reliable layer adhesion. PLA chemistry ensures low shrinkage and reduced risk of warping compared with higher-temperature materials, simplifying bed adhesion and first-layer reliability. The Oh My Gold blend delivers a visually distinct metallic effect without requiring special printing hardware. Minimal odor and easy post-processing, such as sanding and light polishing, make this filament suitable for indoor use and finishing workflows.

Suitable for

• Decorative objects and display pieces
• Scale models and miniatures
• Prototypes where surface finish and color matter
• Hobbyist prints and non-structural parts

Key specifications

• Material: Polylactic Acid (PLA) blend
• Nominal diameter: 1.75 mm
• Spool weight: 1 kg gross filament weight
• Recommended print technology: FDM/FFF
• Finish: metallic gold-effect blend

How to use

Load the filament into any 1.75 mm-compatible extruder and set the printer to typical PLA printing temperatures and speeds recommended by your machine or slicer. Ensure the nozzle and bed are clean and calibrated, and use a suitable build surface or adhesion aid to secure the first layer. Monitor initial extrusion to confirm steady flow and adjust retraction settings if stringing occurs. After printing, allow parts to cool before removal to preserve dimensional accuracy and surface finish.

Usage recommendations

Use standard PLA nozzle temperatures (typically 190–220 °C) and a bed temperature up to 60 °C if required for improved adhesion. Print at moderate speeds to maintain the metallic surface appearance, and perform light post-processing like sanding and polishing for enhanced sheen. Store the spool in a dry environment or sealed container with desiccant to maintain filament quality.
