Silk PLA+ Raven Black by NFIL3D is a glossy, silk-finish 3D printer filament designed for makers, designers, artists and hobbyists who want decorative 3D prints with an elegant black appearance. Made for compatible FDM and FFF 3D printers, this filament offers a reflective, silk-like surface that can enhance the appearance of sculptures, decorative objects, personalised gifts, display models and creative prototypes.

Featuring a nominal filament diameter of 1.75mm, Silk PLA+ Raven Black is intended for printers that support suitable PLA-based materials and the required extrusion temperatures.

The Raven Black colour provides a deep, neutral appearance, while the silk-style formulation adds a reflective surface effect that can make curved shapes and visible outer walls stand out.

Unlike conventional matte or solid PLA filaments, silk-style materials are developed primarily to provide an attractive surface finish. Actual printing performance, strength and appearance depend on the formulation and printing conditions.

Why Choose Silk PLA+ Raven Black?

Silk PLA+ Raven Black is an option for projects where appearance is an important design requirement.

Its glossy black finish can provide a polished look for decorative models without requiring the same finishing process as sanding, painting or applying a separate glossy coating.

The material is suitable for visible design components, artistic sculptures, ornamental objects and product presentation models.

Its 1.75mm diameter is intended for compatible filament-based 3D printers.

The silk effect is influenced by print temperature, speed, surface geometry and cooling. Users should calibrate their settings for the chosen machine.

Although the filament is marketed as PLA+, no specific percentage increase in strength or impact resistance should be assumed without product-specific test documentation.

Key Features and Benefits of Silk PLA+ Raven Black

1. Glossy Silk-Like Surface Finish

The most distinctive feature of Silk PLA+ Raven Black is its reflective silk-style appearance.

The filament is designed to create a smooth-looking, glossy surface on suitable printed models.

This effect is especially attractive on decorative objects with curved surfaces, rounded edges and large visible walls.

Models such as vases, sculptures, figurines and display objects can benefit from the material’s reflective finish.

The actual amount of gloss depends on printing temperature, speed, layer height, extrusion consistency and model geometry.

A suitable material profile is important for achieving consistent results.

2. Deep Raven Black Colour

Silk PLA+ Raven Black combines a dark black shade with a decorative sheen.

The neutral colour works well for modern sculptures, artistic displays, home decorations and presentation models.

Black can also complement other filament colours in multi-part assemblies.

Different lighting conditions may change the perceived amount of shine on the printed surface.

For projects requiring colour consistency, test a sample model before producing multiple matching objects.

3. Nominal 1.75mm Filament Diameter

The filament has a nominal diameter of 1.75mm.

This is a commonly used filament size for desktop FDM and FFF 3D printers.

Users should check their printer’s extruder and hotend specifications before loading the material.

The slicer must be configured for the correct filament diameter.

The exact manufacturing tolerance should be confirmed from NFIL3D’s current product specifications rather than assumed from another filament range.

4. PLA-Based Printing Characteristics

Silk PLA+ Raven Black is intended to provide the decorative appearance of silk-finish material while using a PLA-based printing process.

PLA materials are widely used for models, prototypes, educational projects and decorative objects.

Many PLA-based filaments are suitable for open-frame printers with an appropriate hotend and build surface.

However, silk additives can change how the filament flows, bonds between layers and responds to extrusion settings.

Users should start with a compatible silk PLA or PLA+ profile rather than assume that every standard PLA setting will provide the best finish.

5. Suitable for Decorative 3D Printing

The reflective black finish makes this filament particularly suitable for decorative models.

Examples include sculptures, small statues, ornamental vases, display objects and customised decorations.

The glossy surface can emphasize contours and other visible features of the model.

For the best visual result, consider printing orientation and the placement of the seam.

A carefully selected outer-wall speed can also help maintain a uniform appearance.

6. Attractive Surface Detail

Silk PLA+ Raven Black can be used for prints with raised patterns, curved features and decorative textures.

When the printer is correctly calibrated, the silk finish can highlight design contours and visual details.

Layer height and nozzle diameter influence the finished appearance.

A 0.4mm nozzle with an appropriate layer height is a practical starting configuration for many decorative models.

The final detail quality also depends on printer calibration, cooling and slicing settings.

7. Suitable for Artistic and Creative Projects

This filament can support many creative FDM printing applications.

Artists can use it for sculptures, abstract designs, decorative letters and display pieces.

Designers can produce appearance prototypes and presentation models.

Hobbyists may create miniature vehicles, decorative figurines, ornaments and personalised accessories.

For projects where mechanical performance is critical, a material selected specifically for strength may be more appropriate.

8. Useful for Product Presentation Models

Silk PLA+ Raven Black can provide a visually distinctive finish for product concepts and presentation prototypes.

It is suitable for non-critical display housings, visual mock-ups and decorative design demonstrations.

The glossy black appearance can help communicate the intended shape of a product.

However, surface appearance should not be confused with engineering performance.

Confirm the material’s actual mechanical and thermal specifications before using printed parts under significant loads.

9. Compatible with Suitable FDM Printers

This filament is designed for compatible FDM and FFF printers using 1.75mm PLA-based materials.

Printer compatibility depends on the machine’s filament diameter, hotend capability, extrusion system and slicing profile.

Direct-drive and Bowden printers may both be able to print suitable silk PLA materials when correctly configured.

The ideal retraction and speed settings depend on the machine.

The filament is not intended for liquid-resin MSLA printers.

10. Moisture-Conscious Storage

Like other PLA-based filaments, silk material should be protected from excessive moisture.

Filament exposed to unsuitable humidity can develop extrusion problems, stringing, bubbling or an inconsistent surface finish.

Store the spool in a sealed bag or suitable dry storage container.

If drying becomes necessary, use a procedure approved for the material and spool.

Excessive drying temperatures may deform the spool or filament.

11. Colour and Surface Consistency

Silk PLA+ Raven Black is intended to offer a consistent black appearance when processed under suitable printing conditions.

For the best results, maintain stable nozzle temperature, wall speed and extrusion flow.

Different printing speeds can produce visibly different surface finishes.

Use a small calibration object to compare settings before printing a large decorative model.

Silk PLA+ Raven Black Technical Specifications

Recommended Printing Settings for Silk PLA+ Raven Black

The following settings are general starting recommendations for silk PLA-style filaments. They are not independently validated settings for NFIL3D’s exact Raven Black formulation.

Nozzle Temperature: Approximately 205–230°C

Silk PLA+ Raven Black may require temperature adjustments to obtain the desired glossy finish.

Different silk PLA products have different temperature requirements.

Begin with the recommended temperature on the filament packaging.

If the finish appears inconsistent, use a temperature tower to identify a suitable setting.

Excessive heat may increase oozing, stringing or surface defects.

Heated Bed Temperature: Approximately 50–60°C

A moderately heated build plate is a common starting point for PLA-based filaments.

The correct bed temperature depends on the printer and build surface.

Make sure the first layer is properly calibrated before starting a large model.

Layer Height: 0.20mm Starting Point

For a standard 0.4mm nozzle, 0.20mm layer height is a practical starting setting.

Lower layer heights can improve visible details on suitable models.

The ideal setting depends on the design and the required finish.

Outer Wall Speed

Start with a moderate outer-wall speed, such as 30–50mm/s on a suitable printer.

Slower visible-wall printing can help users evaluate gloss and surface consistency.

Actual speed capability depends on the filament formulation and machine.

Cooling

Use appropriate PLA-style cooling, adjusting it for bridges, overhangs and short layers.

Cooling requirements can differ between silk formulations.

Retraction

Calibrate retraction based on the extruder system.

If stringing occurs, review nozzle temperature, moisture exposure and retraction settings.

Print Orientation

Orient decorative models to emphasize their visible surfaces.

Reduce unnecessary supports on glossy areas, because support removal may leave marks.

Filament Storage

Store unused filament in sealed, dry conditions away from excessive heat and sunlight.
