Carbodeon uDiamond® Nanodiamond PLA Filament - 500g
Carbodeon uDiamond® PLA – Nanodiamond-Enhanced Engineering Filament
Carbodeon uDiamond® PLA is a specialist engineering PLA filament enhanced with functionalised nanodiamond particles to deliver exceptionally high stiffness, improved thermal performance and strong layer-to-layer adhesion while retaining the relatively straightforward printing characteristics of PLA.
Unlike conventional carbon-fibre or glass-fibre reinforced filaments, uDiamond® uses extremely small, spherical nanodiamond particles rather than abrasive chopped fibres. This allows the material to provide significant mechanical reinforcement while remaining nozzle-friendly.
With a stated Young’s modulus of 6,500 MPa and Heat Deflection Temperature of 95°C, uDiamond® PLA is particularly suited to rigid functional components, prototypes, jigs, fixtures and engineering applications where dimensional stability is more important than the properties offered by standard general-purpose PLA.
This product listing is for Natural, 1.75 mm diameter, supplied on a 500 g spool.
Key Performance Benefits
- Exceptional stiffness: Young’s modulus of 6,500 MPa provides very high rigidity for functional printed components.
- Nanodiamond reinforcement: Functionalised nanodiamond particles reinforce the PLA polymer structure without relying on conventional chopped carbon or glass fibres.
- Nozzle-friendly: The spherical nanodiamond particles are non-abrasive, helping avoid the accelerated nozzle wear commonly associated with fibre-reinforced filaments.
- Improved thermal performance: A Heat Deflection Temperature of 95°C provides greater heat resistance than typically expected from standard PLA materials.
- High-speed printing capability: Enhanced thermal conductivity supports printing speeds of up to 500 mm/s when used with suitable printer hardware, geometry and settings.
- Good interlayer performance: Functionalised nanodiamond particles interact with the parent PLA polymer and are designed to improve bonding between printed layers.
- Accessible engineering material: Provides specialist mechanical properties without requiring the very high nozzle temperatures associated with materials such as PA-CF, PPS-CF or PEEK.
What Makes uDiamond® PLA Different?
Many engineering filaments achieve additional stiffness by incorporating chopped carbon fibre or glass fibre. These materials can perform extremely well, but the fibres are abrasive and generally require a hardened or wear-resistant nozzle.
Carbodeon takes a different approach.
uDiamond® PLA contains functionalised nanodiamond particles measuring only a few nanometres in size. Their spherical geometry means they do not behave like abrasive fibres during extrusion. Instead, Carbodeon uses the particles to modify the mechanical and thermal behaviour of the PLA polymer.
The result is a material aimed particularly at applications requiring high rigidity, dimensional stability, thermal performance and efficient printing, while retaining the convenience of a PLA-based filament.
Why Choose Carbodeon uDiamond® PLA?
Choose uDiamond® PLA when your application requires substantially more rigidity and thermal performance than conventional PLA, but you would prefer to avoid the abrasion and printer requirements associated with many carbon- or glass-fibre engineering filaments.

High Stiffness – What Does 6,500 MPa Mean?
One of the standout characteristics of uDiamond® PLA is its 6,500 MPa tensile modulus, or Young’s modulus.
Young’s modulus measures a material’s resistance to elastic deformation. In practical terms, a higher modulus means that a printed component is more resistant to bending or flexing when a load is applied.
This makes uDiamond® particularly interesting for rigid brackets, fixtures, positioning components, housings and functional prototypes where maintaining shape and dimensional accuracy is important.

Printer Compatibility
Carbodeon uDiamond® PLA is suitable for compatible FDM / FFF 3D printers using 1.75 mm filament and capable of operating within the recommended extrusion-temperature range.
Because the nanodiamond additive is non-abrasive, a specialist hardened nozzle is not normally required. This makes uDiamond® easier to introduce to many desktop and professional FDM systems than conventional carbon- or glass-fibre reinforced materials.
Typical compatible open-material platforms may include appropriate models from manufacturers such as:
- Bambu Lab
- Prusa Research
- Raise3D
- Creality
- Anycubic
- FlashForge open-material systems
- Other compatible 1.75 mm FDM / FFF printers

Frequently Asked Questions
What is Carbodeon uDiamond® PLA?
uDiamond® PLA is a specialist PLA filament containing functionalised nanodiamond particles. The particles reinforce the polymer structure and are used to improve stiffness, thermal performance and interlayer adhesion.
Is uDiamond® PLA a carbon-fibre filament?
No. uDiamond® does not use chopped carbon fibres. Its reinforcement comes from nanoscale, functionalised diamond particles dispersed within the PLA polymer.
Do I need a hardened nozzle?
Normally, no. Carbodeon’s nanodiamond particles are spherical and non-abrasive, so the filament does not produce the same type of nozzle wear associated with conventional carbon- or glass-fibre filled filaments.
How stiff is uDiamond® PLA?
Carbodeon states a Young’s modulus of 6,500 MPa. This makes rigidity one of the key characteristics of the material and makes it particularly suitable for dimensionally stable functional components.
What is the Heat Deflection Temperature?
The manufacturer states a Heat Deflection Temperature of 95°C. Actual component performance will depend on print orientation, geometry, loading and processing conditions.
Can uDiamond® PLA really print at 500 mm/s?
Carbodeon states a printing-speed range of 50–500 mm/s. Achieving speeds towards the upper end requires a printer and hotend capable of supplying sufficient melt flow while maintaining dimensional accuracy and layer quality. It should not be treated as the default speed for every machine or model.
Is this filament suitable for normal desktop FDM printers?
Yes, provided the printer accepts third-party 1.75 mm filament and can operate within the recommended extrusion-temperature range. Settings should be validated on the individual machine before producing functional parts.
What colour and spool size does Daemon 3D Print supply?
This product listing is for a 500 g spool of Natural uDiamond® PLA in 1.75 mm diameter. Grey 1.75 mm may also be available separately.
Is uDiamond® PLA stronger than carbon-fibre filament?
Not necessarily. Stiffness, tensile strength, toughness and impact resistance describe different properties. uDiamond® PLA is particularly notable for its high stiffness. A carbon-fibre engineering polymer may be more appropriate where higher tensile strength, chemical resistance or much higher operating temperatures are required.
What applications is uDiamond® PLA best suited to?
Typical uses include engineering prototypes, jigs, fixtures, robotics components, brackets, positioning components, housings and other applications where high rigidity and dimensional stability are important.
Why use nanodiamond particles instead of carbon fibre?
Carbodeon uses nanoscale spherical particles rather than chopped fibres. This allows the PLA to be reinforced without introducing the same abrasive nozzle wear normally associated with conventional carbon- or glass-fibre filled materials.
Should I start printing at 500 mm/s?
No. For a new printer and filament combination, begin with conservative PLA speeds and first validate extrusion, layer adhesion, dimensional accuracy and surface quality. Increase speed only when the printer and hotend can maintain sufficient material flow.
