PLA filament ROSA3D Magic Silk 1.75 mm Midnight City, 300 g spool

ROSA3D Magic Silk PLA 1.75 mm in the "Midnight City" shade is a 300 g spool of silk-finish polylactic acid filament for FDM/FFF 3D printers that accept 1.75 mm PLA. Designed to deliver a smooth satin surface, this PLA filament balances reliable extrusion with an attractive reflective look suitable for decorative objects, display pieces and visual prototypes. The material preserves typical PLA characteristics such as low warping and easy printing at moderate temperatures, while the silk formulation enhances surface uniformity and light reflection for improved appearance without post-processing.

Advantages

The silk finish provides a consistent satin sheen that reduces visible layer lines and highlights fine details. The filament offers stable diameter and good layer adhesion, which supports predictable extrusion and fewer print failures. Its PLA base ensures lower odor during printing and reduced tendency to warp compared with higher-temperature materials, making it suitable for desktop printers and controlled-environment setups. The 300 g spool format is compact and convenient for small projects, samples, and color tests.

Suitable for

• Decorative models and ornaments with a satin appearance
• Visual prototypes and presentation parts
• Miniatures and display pieces where surface finish matters
• Small functional parts compatible with PLA mechanical properties
• Color tests, samples and short-run prints

Key specifications

• Material: PLA (silk-finish)
• Diameter: 1.75 mm nominal
• Spool mass: 300 g
• Color / finish: "Midnight City" silk (satin reflective finish)
• Intended printing method: FDM / FFF

How to use

Load the 1.75 mm filament into your FDM/FFF printer according to the manufacturer's filament handling instructions. Recommended print settings for PLA silk typically include a nozzle temperature in the range suggested for standard PLA (start testing near your printer's typical PLA temperature and adjust in 5 °C increments for optimal flow), bed temperature if used set to low or off depending on adhesion method, and moderate print speed to preserve surface quality. Use appropriate retraction settings to minimize stringing and ensure proper cooling to support layer definition. If necessary, calibrate extrusion multiplier and first layer height to achieve consistent lines and adhesion.

Usage recommendations

For best surface results, print with reduced layer height and moderate speed, enable part cooling after the first few layers, and store the spool in a dry environment or sealed container with desiccant when not in use. Avoid high-temperature or outdoor applications where PLA mechanical and thermal limits may be exceeded.
