Kexcelled THE K5 PETG Matte Filament 1.75mm - 1KG
Kexcelled THE K5™ PETG M Matte Filament – 1.75mm
Kexcelled THE K5™ PETG M is a 1.75mm matte PETG filament developed for functional parts, prototypes and finished models where both mechanical performance and surface appearance matter.
It combines the toughness, rigidity and impact resistance associated with PETG with a low-reflection matte surface that helps disguise visible layer lines. This makes printed components look more consistent straight from the printer and can reduce the amount of cosmetic post-processing required for presentation parts, housings and display models.
THE K5 PETG M supports print speeds of up to 200mm/s with suitable hardware and settings. It is available in 1kg, 3kg and 5kg reel sizes and a broad range of muted, neutral and vibrant colours for prototyping, workshop use and repeat production.
Key Material Benefits
- Matte surface finish: The non-reflective finish reduces glare and helps disguise individual layer lines for cleaner-looking printed parts.
- Durable PETG base: High mechanical strength, rigidity and impact resistance make the material suitable for functional as well as decorative components.
- Up to 200mm/s print speed: Suitable printers can use higher printing speeds for prototypes, production parts and larger batch-printing workflows.
- Low-odour printing: Kexcelled specifies the material as low odour during normal processing.
- Multiple reel sizes: Available in 1kg, 3kg and 5kg formats to suit individual projects and higher-volume material use.
Matte PETG for Functional and Presentation Parts
The main advantage of THE K5 PETG M is its combination of a refined matte appearance with the practical characteristics expected from PETG. The reduced-glare surface helps make printed geometry easier to view while minimising the visual prominence of layer lines.
This is particularly useful when producing housings, covers, prototypes, presentation models and finished products that need to look clean without relying heavily on sanding, filling or painting after printing.
Unlike purely appearance-focused materials, THE K5 PETG M is also intended for functional use. Its PETG formulation provides mechanical strength, impact resistance and rigidity for parts that need to do more than simply look good.
Recommended Applications
Functional Prototypes
The combination of PETG durability and a clean matte finish makes THE K5 PETG M useful for functional prototypes that may also be presented to customers, colleagues or project stakeholders.
Housings, Covers and Enclosures
Its rigidity and low-reflection appearance suit equipment covers, electronics housings, cases and other components where both mechanical performance and surface quality are important.
Display and Presentation Models
The matte surface helps minimise visible layer lines and reflections, making the material well suited to architectural models, product mock-ups, demonstration pieces and other presentation-focused prints.
Workshop and Everyday Functional Parts
Brackets, fixtures, organisers, accessories and general workshop components can benefit from the toughness of PETG while retaining a more refined finish than conventional glossy PETG.
Reduced Layer-Line Visibility Without Moving Away from PETG
Standard PETG can produce strong functional prints but often has a naturally glossy surface that emphasises reflections and visible print layers. THE K5 PETG M uses a matte formulation that reduces surface glare and makes layer transitions less visually prominent.
This can be particularly useful for:
- Product prototypes intended for presentations or photography
- Finished housings and enclosures
- Display models and decorative parts
- Cosplay props and accessories
- Functional prints where appearance still matters
Material Properties
THE K5 PETG M balances visual finish with the thermal and mechanical behaviour of a functional PETG filament. Its approximately 75°C glass transition temperature and 74°C heat deflection temperature provide more thermal capability than materials intended primarily for low-temperature decorative use, although it should not be treated as a high-temperature engineering polymer.

Kexcelled's recommended parameters are based on a 0.4mm nozzle and a frosted PEI build surface. The manufacturer does not specify a hardened nozzle requirement for THE K5 PETG M.
Recommended Printing Parameters
The following manufacturer values provide a starting point for THE K5 PETG M. Final settings may vary depending on the printer, geometry, environment and required surface finish.
| Setting | Recommended Value | Practical Guidance |
|---|---|---|
| Nozzle Temperature | 230–260°C | Adjust within the range according to print speed, flow rate and layer adhesion requirements. |
| Bed Temperature | 70–80°C | A heated bed supports first-layer adhesion and dimensional stability. |
| Build Surface | Frosted PEI | Kexcelled's recommended surface for its published print parameters. |
| Cooling Fan | 0–50% | Cooling can be adjusted according to geometry, bridging and required interlayer bonding. |
| Layer Height | 0.2mm | The manufacturer's reference setting using a 0.4mm nozzle. |
| Shell Thickness | ≥0.8mm | Provides a manufacturer-recommended baseline for wall construction. |
| Print Speed | Up to 200mm/s | Actual achievable speed depends on hotend flow capability, acceleration and part geometry. |
| Reference Nozzle | 0.4mm | Kexcelled's published settings are based on a 0.4mm nozzle. |
Printing Guidance
- Start within the manufacturer temperature range: Begin with a nozzle temperature between 230°C and 260°C and adjust according to extrusion quality, print speed and layer bonding.
- Use a heated build plate: A bed temperature between 70°C and 80°C is recommended, with Kexcelled using frosted PEI for its reference settings.
- Tune cooling to the model: Kexcelled recommends 0–50% active cooling. Lower cooling can favour layer bonding, while additional cooling may help with smaller details and bridging.
- Increase temperature when increasing flow: Higher print speeds normally require sufficient hotend flow and stable extrusion. Do not assume every printer can produce identical results at the maximum 200mm/s figure.
- Store the filament carefully between prints: Keep the reel protected from unnecessary exposure to moisture and contamination when not in use.

Important Considerations
- The matte surface helps reduce the appearance of layer lines but does not eliminate them completely; final appearance still depends on layer height, calibration, geometry and print settings.
- The 200mm/s figure is a maximum manufacturer recommendation and requires a printer and hotend capable of maintaining sufficient material flow.
- With an HDT of 74°C, THE K5 PETG M should not be treated as a high-temperature engineering filament for applications exposed to sustained temperatures approaching its softening range.
- Kexcelled's published reference settings use a 0.4mm nozzle and frosted PEI build surface, so different hardware may require additional tuning.
Storage and Handling
- Keep filament protected from unnecessary moisture exposure when not in use.
- Store reels in a clean, dry environment and reseal opened material where practical.
- Keep the filament path and spool free from dust and contamination that could affect extrusion consistency.
- Allow material stored in a significantly colder environment to reach normal room conditions before printing.
- Refer to the latest Kexcelled technical and safety documentation where application-specific handling information is required.

Frequently Asked Questions
What is Kexcelled THE K5 PETG M?
Kexcelled THE K5 PETG M is a 1.75mm matte PETG filament designed to combine the toughness and rigidity of PETG with a low-reflection surface finish. The matte texture helps disguise visible layer lines and gives printed parts a softer, more consistent appearance.
What temperature should I print Kexcelled K5 PETG M at?
Kexcelled recommends a nozzle temperature between 230°C and 260°C and a heated bed between 70°C and 80°C. These should be treated as starting ranges, with final settings adjusted according to the printer, hotend, print speed and model geometry.
How fast can Kexcelled K5 PETG M be printed?
The manufacturer specifies print speeds of up to 200mm/s. Reaching this speed reliably depends on the printer's motion system, hotend flow capacity, nozzle size, layer height and the complexity of the model.
Does K5 PETG M need a hardened nozzle?
Kexcelled does not specify a hardened nozzle requirement for THE K5 PETG M. Its published printing parameters are based on a standard 0.4mm nozzle. This differs from abrasive carbon-fibre or glass-fibre reinforced materials that commonly require wear-resistant nozzle materials.
Does Kexcelled K5 PETG M hide layer lines?
The matte, low-reflection surface helps make layer lines less visually prominent than they may appear on glossy materials. It does not physically remove layer lines, so layer height, calibration and model geometry still affect the final surface quality.
What can I print with matte PETG?
Typical applications include functional prototypes, equipment housings, covers, enclosures, workshop parts, display models, cosplay accessories and presentation pieces. It is especially useful where a functional PETG part also needs a clean finished appearance.
What build surface does Kexcelled recommend for K5 PETG M?
Kexcelled's published settings specify a frosted PEI build surface with a bed temperature of 70–80°C. Other suitable FDM build surfaces may also work, but adhesion behaviour and temperature requirements can vary between printers and surfaces.
