Detail, surface character and colour can matter for models and presentation parts.
Toughness, stiffness, wear and load requirements influence material choice.
Heat, sunlight, moisture and chemicals can rule some materials in or out.

The Best Material Depends on the Job, Not Just the Model
A detailed display piece and a workshop bracket may use the same printing process but need very different material properties.
Think about where the part will be used, how it will be loaded, whether it needs to flex, how much heat it may see, whether it will be exposed to sunlight or moisture, and whether appearance or mechanical behaviour is the priority.
Questions to ask before choosing a material
- Is the part mainly visual or functional?
- Will it experience impact, wear or mechanical load?
- Does the part need to flex or compress?
- Will it be exposed to heat?
- Will it be used outdoors or in direct sunlight?
- Will moisture or chemicals be present?
- Is dimensional stability or surface detail the priority?
Compare the Main 3D Printing Materials
These summaries are a starting point. Final suitability still depends on the model, orientation, design and actual application.
PLA
General purposeWell suited to detailed prototypes, models, display pieces and many low-stress indoor applications.
- Good detail and print quality.
- Rigid material.
- Useful for visual and concept parts.
- Not the first choice for high-heat use.
PETG
ToughA practical general-purpose option where improved toughness, moisture resistance and durability are useful.
- Tougher than PLA for many uses.
- Useful moisture resistance.
- Good for suitable functional parts.
- Useful all-round material.
ABS
Heat resistantSuitable for selected mechanical parts and applications needing improved temperature resistance.
- Improved heat resistance over PLA.
- Suitable for selected mechanical use.

PEBA 90A
High reboundLightweight flexible material for suitable parts needing elastic recovery, cushioning or repeated dynamic movement.
- High elastic recovery.
- Useful for dynamic cushioning.
- Suitable for repeated flexing.

Which Material Should I Start With?
Use this as a broad guide, then confirm the actual requirements of your part before ordering.
| Material | Common Strength | Best Starting Point For | Consider If You Need |
|---|---|---|---|
| PLA | Rigid, detailed, easy to finish visually | Models, prototypes, display pieces, low-stress parts | Detail and appearance |
| PETG | Tough, durable, moisture-resistant | General functional parts and practical components | A good all-round functional option |
| ABS | Tough with improved heat resistance | Selected mechanical and warmer environments | Higher temperature resistance than PLA |
| ASA | Outdoor-oriented with UV resistance | Outdoor brackets, covers and suitable exterior parts | Sunlight and weather exposure |
| TPU | Flexible and resilient | Protective, flexible and compressible components | Bending, cushioning or flexibility |
| PEBA 90A | Flexible, lightweight and high-rebound | Dynamic prototypes, cushioning and repeated-flex parts | Elastic recovery and lower flexible-part weight |
| Nylon | Tough and wear-resistant | Selected engineering and higher-stress applications | Wear resistance and toughness |
Carbon-Fibre & Glass-Fibre Options for Selected Applications
Selected materials are available in reinforced forms where added stiffness, dimensional behaviour or other engineering properties may be useful.
Reinforced filament is not automatically the best choice for every “strong” part. Final performance still depends on the base polymer, geometry, wall thickness, print orientation, load direction and the way the part is used.
Consider reinforced material when
- Increased stiffness is useful.
- Dimensional stability matters.
- The base polymer suits the environment.
- The part geometry supports the intended load.
- The added material cost is justified by the application.
Choose Based on the Environment and Function
Define the Use
Decide whether the part is primarily visual, functional, flexible, structural, outdoor or wear-related.
Check the Environment
Consider heat, sunlight, moisture, chemicals, impact and movement.
Choose the Material
Select the available filament that best matches those requirements.
Test the Part
For functional use, evaluate the finished component under appropriate conditions before relying on it operationally.
Functional performance can depend on
- Material type.
- Part geometry.
- Wall thickness.
- Infill and internal structure.
- Print orientation.
- Layer adhesion.
- Load direction.
- Operating temperature and environment.
A Stronger Filament Does Not Fix a Poorly Designed Part
FDM parts are built layer by layer, so print orientation and design can affect strength, surface finish, dimensional accuracy, support requirements and print time.
For demanding functional applications, material selection should be considered together with geometry, load direction and testing rather than treated as a standalone strength rating.
Available Colours Depend on Material and Current Stock
The same colour range is not always available in every material. Current selectable colours are shown in the online quote system where applicable.
Colour-sensitive project?
For branding, replacement parts, display pieces or matching an existing object, tell us what you are trying to match before ordering.
Different Services Often Prioritise Different Material Properties
Prototypes
Prioritise detail, fit, appearance or suitable functional behaviour depending on what the prototype needs to prove.
Replacement Parts
Consider heat, sunlight, moisture, wear and mechanical loading before choosing the replacement material.
Functional Parts
Material, geometry, orientation and testing all matter for mechanically useful printed components.
Small-Batch Production
Finalise and test the material choice before repeating the same configuration across a production batch.
Common Questions About 3D Printing Materials
What 3D printing materials does 3D Print It offer?
Available materials include PLA, PETG, ABS, ASA, TPU, PEBA 90A and Nylon, with selected carbon-fibre and glass-fibre reinforced options also available. Current choices depend on material and stock availability.
Which filament should I choose?
It depends on what you are making. PLA is a strong starting point for models, prototypes and many general-purpose parts. PETG offers improved toughness and moisture resistance, while ABS, ASA, TPU, PEBA 90A, Nylon and reinforced options may be more appropriate where heat, outdoor durability, flexibility, rebound, wear or other engineering requirements matter.
Which material is best for outdoor parts?
ASA is commonly selected where improved UV and weather resistance are important. The correct material still depends on temperature, load, geometry and other environmental requirements.
Which material is best for flexible parts?
TPU is the main general-purpose flexible option for suitable parts that need to bend, compress or provide a rubber-like interface. PEBA 90A is a specialist alternative where high rebound, lower weight or repeated dynamic movement is more important.
Can I choose the colour?
Yes. Available colours depend on the material and current filament stock. The online quote system shows the current selectable options.
Can you exactly colour-match an existing part?
We can try to select a visually close filament, but exact colour matching cannot always be guaranteed because filament manufacturers, batches, lighting conditions and display screens can vary.
