PLA Silk 1.75mm 3D Printer Filament – Single, Dual, Tri-Color Rainbow 1Kg
Description
PLA Silk 1.75mm 3D Printer Filament – Single, Dual, Tri-Color & Rainbow 1Kg
EXTRUTEX PLA Silk 3D Printer Filament is a premium decorative and functional 3D printing filament developed for users who want more than ordinary PLA. Designed in Austria and manufactured in China at EXTRUTEX production facilities in Shanghai and Nanjing, this 1.75mm PLA Silk filament combines smooth extrusion, excellent layer adhesion, dimensional accuracy and a distinctive high-gloss silk appearance.
Available in single-color, dual-color, tri-color and rainbow color configurations, the filament creates vivid visual effects that can transform ordinary FDM prints into highly attractive decorative models, prototypes, gifts, display parts and functional objects. The multi-color versions are particularly designed for seamless color transitions and fast color-changing effects, with color changes occurring approximately every 5–10 meters depending on the selected color configuration and printing conditions.
With a recommended printing temperature of 200–225°C, a filament diameter tolerance of approximately ±0.02mm, high material purity and carefully controlled production, EXTRUTEX PLA Silk provides a stable feeding and extrusion experience across a wide range of 1.75mm FDM/FFF 3D printers.
Premium Silk PLA for High-Impact Visual Results
Traditional PLA is one of the most popular materials in desktop and professional FDM printing because it is easy to print and provides excellent surface quality. Silk PLA takes those characteristics further by introducing a special surface appearance that reflects light across the printed model.
The result is a smooth, glossy and silk-like surface that can make decorative objects appear significantly more refined. The effect is especially noticeable on curved surfaces, figurines, vases, sculptures, ornaments, toys, architectural models and other objects where appearance matters.
EXTRUTEX PLA Silk is formulated to provide a balance between visual appearance and practical printability. The filament is designed for smooth extrusion, reliable layer bonding and consistent dimensional performance while maintaining the characteristic silk finish.
The filament is supplied in 1Kg spools, making it suitable for both individual makers and professional users who require a reliable quantity of material for repeated printing.
Single-Color, Dual-Color, Tri-Color & Rainbow Effects
One of the defining features of this PLA Silk filament family is its broad range of color configurations. Instead of limiting users to conventional single-color filament, EXTRUTEX provides several visual options for creating different artistic and decorative effects.
Single-Color Silk PLA
Single-color silk PLA provides a consistent metallic-like, glossy or silk appearance throughout the spool. It is an excellent choice when a uniform visual identity is required for a complete model, product prototype, display object or decorative component.
Dual-Color Silk PLA
Dual-color filament combines two coordinated colors to create changing visual effects as the model is printed. Depending on the orientation of the surface and lighting conditions, the finished object can display different shades and reflections.
Tri-Color Silk PLA
Tri-color filament adds another dimension to the printed appearance. Three coordinated colors can gradually appear across the print, creating attractive transitions without requiring manual filament changes during the printing process.
Rainbow Silk PLA
Rainbow PLA is designed for users who want highly dynamic and colorful prints. The filament transitions through multiple colors, creating a different appearance across the height or length of the finished model.
The fast color-change concept of approximately 5–10 meters provides more frequent visual transitions than many conventional multi-color filaments. The exact appearance depends on the model geometry, layer height, nozzle size, infill, printing speed and orientation.
High-Purity PLA Raw Material
EXTRUTEX PLA Silk filament is produced using carefully selected PLA-based raw materials. The material concept is based on PLA associated with renewable resources such as corn and sugarcane, supporting the use of bio-based feedstocks in the production of PLA filament.
The filament is manufactured without intentionally incorporating recycled filament into the supplied material formulation. This approach supports consistent material properties and helps maintain stable extrusion characteristics from one spool to another.
Material purity is particularly important for FDM printing. Contamination, inconsistent diameter or uncontrolled moisture can result in unstable extrusion, nozzle obstruction, inconsistent layers and poor surface quality. EXTRUTEX production therefore focuses on controlled raw material selection, extrusion and diameter management.
The result is a filament designed for clean feeding, stable melting and reliable deposition through a standard 1.75mm FDM printer nozzle.
±0.02mm Diameter Accuracy
Consistent filament diameter is one of the most important characteristics of a quality 3D printing filament. Variations in diameter directly affect the amount of material delivered through the nozzle.
EXTRUTEX PLA Silk is manufactured with a target dimensional tolerance of approximately ±0.02mm. This level of diameter control helps provide stable material feeding and consistent extrusion throughout the spool.
More consistent filament geometry can contribute to predictable extrusion, smoother surfaces, stable wall thickness and improved dimensional consistency. It is especially valuable for printers operating at higher speeds where extrusion stability becomes increasingly important.
Designed for Smooth and Reliable FDM Printing
PLA Silk is designed to be straightforward to print. It does not require the specialized high-temperature printing environment associated with engineering-grade materials such as PEEK or certain high-performance polyamides.
The recommended printing temperature is approximately 200–225°C. The ideal setting should be adjusted according to the specific printer, nozzle, printing speed, layer height, color formulation and environmental conditions.
Users should always perform a small temperature tower or calibration print when using a new spool or a new printer profile. Silk PLA can produce different gloss levels depending on temperature and printing speed, allowing experienced users to tune the visual appearance of the finished component.
Recommended Starting Parameters
- Filament diameter: 1.75mm
- Recommended nozzle temperature: 200–225°C
- Recommended maximum volumetric flow rate: approximately 20 mm³/s
- Spool weight: 1Kg
- Diameter tolerance: ±0.02mm
- Printing technology: FDM / FFF
- Material: PLA Silk
Actual printing parameters should always be optimized according to the printer manufacturer's recommendations and the desired balance between surface quality, printing speed and silk effect.
High-Speed Printing Performance
Modern desktop 3D printers are becoming increasingly fast, with some machines capable of reaching printing speeds around 300mm/s under suitable conditions. EXTRUTEX PLA Silk is developed with smooth extrusion characteristics suitable for modern FDM printing systems.
The specified maximum volumetric flow rate is approximately 20 mm³/s under internal testing conditions. Actual achievable speed depends on nozzle diameter, extrusion temperature, layer height, cooling performance, printer mechanics and the complexity of the printed model.
High-speed printing should always be balanced against surface appearance. When printing silk PLA, users may find that moderate speeds produce a stronger visual gloss, while higher speeds can be useful when productivity is the priority.
Excellent Interlayer Adhesion
Strong bonding between individual printed layers is essential for producing reliable 3D printed components. Poor interlayer bonding can lead to cracks, delamination and reduced mechanical strength.
EXTRUTEX PLA Silk is formulated to provide strong interlayer adhesion under properly optimized printing conditions. This helps reduce the risk of layer separation and contributes to stable printed structures.
Proper nozzle temperature, cooling, print speed and environmental conditions remain important factors. For maximum strength, users should ensure that the selected temperature provides sufficient layer fusion without causing excessive stringing or loss of fine details.
High-Gloss Silk Surface Finish
The signature feature of Silk PLA is its appearance. The material produces a smooth, reflective surface that can resemble polished silk or a metallic decorative finish.
The high-gloss appearance is particularly effective on models with flowing curves and relatively large visible surfaces. Light interacts with the surface differently as the viewing angle changes, creating a dynamic visual effect.
For designers and product developers, this means a printed prototype can look much closer to a finished consumer product without extensive sanding, painting or post-processing.
Silk PLA is therefore particularly popular for decorative products, figurines, artistic models, home decoration, promotional objects, cosplay accessories, display models and personalized gifts.
Nozzle-Friendly Extrusion, Low Blocking & Reduced Stringing
Stable filament quality is important for preventing common printing problems such as nozzle blocking, inconsistent extrusion and excessive stringing.
EXTRUTEX PLA Silk is manufactured with controlled extrusion and diameter consistency to support smooth feeding through the printer system. Proper storage and drying are also important because PLA can absorb moisture from the surrounding environment.
When stored correctly and printed within the recommended temperature range, the filament is designed to provide clean extrusion with reduced stringing and reliable material flow.
For best results, keep the spool sealed when not in use and use a filament dryer when printing in high-humidity environments or when the material has been exposed to moisture for an extended period.

Mechanical Performance
Although PLA Silk is primarily selected for its visual appearance, it also provides useful mechanical performance for many general-purpose 3D printing applications. Under the supplied test data, the filament demonstrates a bending strength of approximately 90 MPa in the XY direction, with an impact strength of approximately 6 KJ/m².
The reported tensile strength in the Z direction is approximately 19 MPa, while the reported bending strength in the Z direction is approximately 22 MPa. These values demonstrate the importance of print orientation when mechanical performance is a critical requirement.
Like all FDM materials, final mechanical properties depend not only on the filament itself, but also on layer height, infill percentage, wall thickness, nozzle temperature, print speed, cooling and model orientation.

Broad Compatibility with 1.75mm FDM 3D Printers
EXTRUTEX PLA Silk is designed for broad compatibility with modern 1.75mm FDM/FFF 3D printers. The filament can be used with many popular desktop and professional printer platforms when operated within their recommended material parameters.
Compatibility includes printers from brands such as Creality, Bambu Lab, Anycubic, Prusa and Flashforge, provided the printer is configured for standard 1.75mm PLA-type filament.
Before printing, users should verify the printer's nozzle temperature range, filament diameter requirements and extrusion settings. A properly calibrated printer will deliver the best combination of surface quality, dimensional accuracy and color transition.
Fast Color Change and Seamless Gradient Transitions
Conventional multi-color filament may remain in one color for a relatively long distance, resulting in large sections of a print appearing in the same shade. EXTRUTEX Silk Rainbow and multi-color filament is designed around a faster transition concept.
With a typical color-change interval of approximately 5–10 meters, the filament can produce more frequent transitions throughout a printed object. This makes it particularly effective for models where color variation across the entire height of the print is desirable.
Because FDM printing deposits material layer by layer, the exact location and visibility of each color transition depends on the size and geometry of the model. A taller model may display more complete transitions, while smaller objects may show only part of a color sequence.
The combination of silk gloss and changing colors creates a distinctive surface that can look different under natural light, studio lighting and different viewing angles.
EXTRUTEX Quality & Production Control
EXTRUTEX PLA Silk filament is developed with an emphasis on consistent raw materials, controlled extrusion and stable filament geometry. Quality control is applied throughout the production process to help maintain reliable performance between batches.
Filament production requires precise control of extrusion temperature, cooling, drawing, diameter measurement and winding. These parameters directly influence how smoothly the final spool feeds through a 3D printer.
EXTRUTEX focuses on maintaining consistent filament dimensions and clean winding so that users can spend more time printing and less time dealing with unnecessary material-related problems.
The result is a practical PLA Silk material designed for makers, designers, product developers, educational institutions, professional model makers and commercial 3D printing operations.
