With a nominal filament diameter of 1.75mm and an advertised diameter tolerance of ±0.015mm, the material is designed to support consistent feeding through compatible extrusion systems. Each spool is specified with a full 1kg net weight of usable filament and includes two desiccants to help manage moisture exposure during storage.
Why Choose Turbo-Finish PLA+ Midnight Grey?
Turbo-Finish PLA+ Midnight Grey combines the professional appearance of a dark neutral colour with the practical characteristics of a high-speed PLA+ formulation.
Midnight Grey is particularly useful for prototypes where bright colours might distract from a model’s shape or structural design. It gives architectural miniatures, product housings and engineering demonstration parts a refined appearance.
The darker grey colour also complements black, white, blue and metallic-looking filament colours in multi-part assemblies.
For makers working with suitable high-speed FDM printers, the Turbo-Finish formulation provides flexibility between conventional printing speeds and faster print profiles.
Its enhanced PLA+ formulation is intended to improve practical strength compared with ordinary PLA, while controlled filament dimensions help maintain consistent material delivery.
Key Features of Turbo-Finish PLA+ Midnight Grey
1. High-Speed Printing Support – 50mm/s to 750mm/s
One of the main advertised features of Turbo-Finish PLA+ Midnight Grey is its printing-speed support range of 50mm/s to 750mm/s.
This makes the material an option for both conventional FDM workflows and high-speed printing systems with suitable hardware.
For prototype development, printing faster may reduce the time needed to produce design samples and repeated components.
However, the advertised maximum speed of 750mm/s does not mean that every 3D printer can maintain acceptable print quality at that speed.
The achievable speed depends on machine acceleration, motion-system design, nozzle diameter, hotend melting capacity, volumetric flow, cooling and model geometry.
Detailed outer walls, small features, bridges and overhangs often require lower speeds to achieve satisfactory quality.
Users should start with a suitable PLA+ profile and increase speed gradually after checking extrusion, surface finish and layer adhesion.
2. Sophisticated Midnight Grey Colour
Turbo-Finish PLA+ Midnight Grey features a dark grey colour intended for professional-looking prototypes and modern creative projects.
Its neutral appearance works well for technology-inspired models, product design samples, miniature equipment and industrial-style decorative objects.
The dark grey shade can help highlight geometric shapes, edges and model contours under suitable lighting.
Midnight Grey also works effectively with contrasting colours such as white, orange, blue and yellow in multi-part printed designs.
NFIL3D emphasizes controlled colour formulation to support consistent appearance across the filament spool.
The final shade and surface sheen may vary depending on nozzle temperature, layer height, printing speed and lighting.
Midnight Grey describes the filament colour; it does not imply a metallic, carbon-fibre, matte or electrically conductive material formulation.
3. Enhanced Strength Compared with Regular PLA
Turbo-Finish PLA+ Midnight Grey uses an enhanced PLA+ formulation intended to provide higher strength than conventional PLA filament.
This makes it useful for selected prototype housings, customized organizers, lightweight accessories and decorative components.
The formulation aims to provide practical handling durability while maintaining familiar PLA-based printing characteristics.
However, the strength of a finished 3D printed object depends on model geometry, wall thickness, infill density, printing orientation and layer bonding.
Printing at very high speeds can affect strength when the hotend cannot provide adequate material flow or bonding.
Parts exposed to high loads, elevated temperatures or safety-critical conditions should be tested before use.
4. Precision 1.75mm Diameter with ±0.015mm Tolerance
Turbo-Finish PLA+ Midnight Grey has a nominal diameter of 1.75mm and an advertised dimensional tolerance of ±0.015mm.
Consistent filament diameter is important because slicing software calculates material delivery using the filament dimensions configured in the printing profile.
Significant diameter variation may contribute to uneven extrusion, irregular layer widths and visible surface defects.
NFIL3D emphasizes dimensional consistency as part of its filament manufacturing approach.
This helps support predictable material feeding when the filament is used with a properly calibrated extruder.
The advertised ±0.015mm tolerance refers specifically to filament diameter, not guaranteed dimensional accuracy of a finished 3D printed part.
5. Nozzle-Friendly PLA+ Formulation
Turbo-Finish PLA+ Midnight Grey is intended for extrusion through compatible FDM and FFF printer hotends.
Its PLA+ formulation and controlled material dimensions are designed to support consistent feeding under suitable operating conditions.
A clean nozzle, correctly calibrated extruder and appropriate printing temperature remain essential for reliable performance.
When printing faster, the hotend must melt enough material to satisfy the requested volumetric flow.
If the hotend reaches its flow limit, users may encounter under-extrusion, gaps or insufficient layer bonding.
For consistent results, choose printing settings that match the printer’s actual capabilities.
No filament can guarantee completely clog-free printing under all operating conditions.
6. Moisture Management with Two Desiccants
Turbo-Finish PLA+ Midnight Grey is supplied with two desiccants intended to help manage humidity exposure during storage.
PLA-based filament can absorb moisture from the surrounding environment over time.
Material affected by excessive moisture may produce stringing, bubbling, rough surfaces and inconsistent extrusion.
The included desiccants support more suitable storage conditions but do not guarantee permanently moisture-free filament.
After opening the spool, store unused filament inside an airtight container or sealed protective bag with suitable desiccant.
For additional technical guidance, read the Prusa Filament Drying and Storage Guide.
7. Full 1kg Net Filament Weight
Each spool of Turbo-Finish PLA+ Midnight Grey is advertised with a full 1kg net weight of usable 3D printing filament.
Net weight refers to the printing material and excludes the empty spool and outer packaging.
This provides material for multiple smaller models or larger individual projects.
Users can estimate filament consumption with slicing software before beginning a print.
Actual consumption depends on model dimensions, wall thickness, infill density and support requirements.
8. Consistent Colour for Multi-Part Projects
Colour consistency is useful when producing several components intended for the same product or decorative assembly.
NFIL3D emphasizes controlled colour formulation to help maintain a uniform Midnight Grey appearance.
Turbo-Finish PLA+ Midnight Grey can be used for matching prototype housings, architectural elements and industrial-style accessories.
Keeping similar printing temperatures, layer heights and outer-wall speeds between print sessions may help reduce differences in shade and surface texture.
9. Backed by 30+ Years of Polymer Expertise
NFIL3D draws on more than 30 years of experience in polymer raw materials, additives and material processing.
This background supports the brand’s approach to material formulation, filament dimensional consistency and manufacturing control.
Turbo-Finish Midnight Grey brings these priorities together with a versatile dark grey colour and manufacturer-advertised high-speed printing support.

Recommended Printing Settings for Turbo-Finish PLA+
For dependable results with Turbo-Finish PLA+ Midnight Grey, start with a compatible PLA+ or high-speed PLA+ printing profile.
Nozzle Temperature: Follow the recommended range on the NFIL3D filament packaging and adjust according to extrusion requirements.
Bed Temperature: Use a suitable heated-bed setting and keep the printing surface clean.
Layer Height: A 0.20mm layer height is a practical starting point when using a standard 0.4mm nozzle.
Printing Speed: Begin at a reliable printer-supported speed and increase gradually after testing extrusion quality and layer bonding.
Outer-Wall Speed: Use controlled speeds for visible surfaces and detailed features even when internal areas are printed faster.
Maximum Volumetric Flow: Ensure the hotend can melt sufficient filament for the selected line width, layer height and print speed.
Acceleration: Choose values suitable for the printer’s motion system and model geometry.
Part Cooling: Adjust cooling according to overhangs, bridges, layer time and material bonding.
Storage: Keep unused filament in a sealed, dry environment with suitable desiccant.
Understanding Volumetric Flow for High-Speed Printing
When using Turbo-Finish PLA+ Midnight Grey, the printer’s volumetric flow capacity must be considered before choosing high speeds.
The approximate calculation is:
Required Volumetric Flow = Line Width × Layer Height × Actual Printing Speed
For example, with a 0.45mm line width and a 0.20mm layer height:
| Actual Printing Speed | Approximate Required Flow |
|---|---|
| 100mm/s | 9mm³/s |
| 200mm/s | 18mm³/s |
| 300mm/s | 27mm³/s |
| 500mm/s | 45mm³/s |
| 750mm/s | 67.5mm³/s |
These values represent theoretical material demand rather than independently verified performance of any specific printer or filament.
Short toolpaths may also prevent the printhead from reaching its configured maximum speed because of acceleration limits.
The selected profile must match the machine’s actual extrusion, motion and cooling capabilities.
Tips for Better Midnight Grey 3D Prints
The finished appearance and strength of Turbo-Finish PLA+ Midnight Grey depend on printer calibration, filament condition and slicing settings.
Maintain consistent outer-wall speeds when printing presentation models or decorative objects.
For detailed geometries, use an appropriate layer height and carefully selected print orientation.
Check first-layer adhesion and build-plate cleanliness before starting large prints.
When increasing printing speed, monitor for ringing, under-extrusion, poor bridging and weak layer adhesion.
If extrusion demand exceeds the hotend’s capacity, reduce print speed or adjust operating settings within the manufacturer’s recommended range.
Purge the nozzle sufficiently when switching from a contrasting colour to avoid unexpected colour mixing.
For larger multi-part projects, use similar slicer settings to maintain a consistent grey appearance.
If stringing, bubbling or rough extrusion occurs, review moisture exposure, nozzle temperature and retraction settings.
