MATERIALS

We choose materials for the application.

3D printing materials: PLA, PETG, ABS, ASA, TPU, nylon, PC, composites, flame-retardant materials and SLA resins. Tell us what your product needs to withstand.

From scale models and enclosures to load-bearing components. We select the material to suit the application, environment and finish you need.

PETG and ABS are also excellent choices for mechanical components.

For many brackets, holders and enclosures, they offer the right balance of performance and printing cost. We tailor the design and print settings to the loads your part needs to withstand.

ALL MATERIALS AT A GLANCE

A single overview of materials for FDM and SLA printing. Compare the ratings at a glance, then expand each material’s benefits and recommendations for more detail.

How to read the comparison

Hatched bars show the range of properties across different material formulations.

PLA

To present a shape or idea

FDM

Architectural models, presentation models and shape checks.

Printing cost
Benefits and recommendations

Advantages

  • Good detail reproduction and a wide choice of colours.
  • A practical choice for visual models used indoors.

Good to know

For heat or sustained mechanical loads, we consider another material. A part in a hot car faces a different challenge from a model on a desk.

PETG

A versatile choice for mechanical components

FDM

Mechanical components, brackets, holders, enclosures and functional prototypes.

Printing cost
Benefits and recommendations

Advantages

  • A good balance of toughness and ease of production.
  • A very good choice for many mechanical components with moderate temperature requirements.

Good to know

For precise fit, high temperatures or specific chemicals, we check the exact formulation and operating conditions.

ABS / ASA

When the environment demands more

FDM

Mechanical components, brackets and enclosures; ASA is also suitable for outdoor parts.

Printing cost
Benefits and recommendations

Advantages

  • ABS is a very good choice for many mechanically loaded components and enclosures.
  • ASA offers an advantage for UV and weather exposure.

Good to know

ABS and ASA are not interchangeable in every environment. We generally consider ASA first for outdoor use and check temperature and load requirements separately.

TPU

When a part needs to flex

FDM

Edge protectors, dampers, flexible covers and grip components.

Printing cost
Benefits and recommendations

Advantages

  • Flexibility instead of rigid plastic.
  • A good choice for parts that need to conform during use.

Good to know

Softness depends on material hardness, walls and shape. TPU is not automatically suitable for every seal or chemical exposure.

PA / nylon

For loads, sliding contact and wear

FDM

Brackets, gears, guides, bushings and load-bearing functional prototypes.

Printing cost
Benefits and recommendations

Advantages

  • A candidate for mechanical applications and wear resistance.
  • Properties can be tailored by choosing the type of nylon.

Good to know

Absorbs moisture, which affects properties and dimensions. We need to understand the operating environment before selecting it.

PC

For more demanding temperatures

FDM

Engineering enclosures and parts requiring stiffness and heat resistance.

Printing cost
Benefits and recommendations

Advantages

  • Good heat resistance and useful stiffness for functional parts.
  • Useful for demanding functional parts.

Good to know

Different PC blends do not have identical resistance. We base the choice on the technical data sheet and part geometry.

CF / GF composites

Fibre-reinforced plastic

FDM

Stiff brackets, jigs and dimensionally stable engineering parts.

Printing cost
Toughness
Hardness
Stiffness

The range covers different base plastics, such as PETG-CF and PA-CF. Fibres primarily increase stiffness; heat resistance and toughness also depend on the base plastic.

Benefits and recommendations

Advantages

  • CF means carbon fibre; GF means glass fibre.
  • Fibres can increase stiffness and change the behaviour of the base material.

Good to know

PA-CF and PETG-CF are different materials. Greater stiffness does not necessarily mean greater toughness or equal strength in all directions.

FR materials

Flame-retardant materials

FDM / SLA

Electronic enclosures and parts with specified flammability requirements.

Printing cost
Toughness
Hardness
Stiffness

The range covers different flame-retardant filaments and resins. FR describes their response to fire, rather than identical heat resistance or mechanical properties.

Benefits and recommendations

Advantages

  • Materials with a documented flammability classification can be selected.
  • Filament and resin formulations are available for different requirements.

Good to know

FR does not mean non-combustible. A material classification does not automatically certify the finished product; wall thickness, process and the required standard matter.

Standard resins

Appearance and fine detail

SLA

Presentation models, small details and visual prototypes.

Printing cost
Benefits and recommendations

Advantages

  • Smooth surfaces and well-defined small features.
  • Suitable for assessing appearance and shape.

Good to know

Standard resin can be brittle. For impacts, flexing or higher temperatures, we choose an appropriate engineering resin.

Specialist resins

Properties for a specific purpose

SLA

Functional prototypes, flexible components and temperature-demanding parts.

Printing cost
Toughness
Hardness
Stiffness

From flexible and tough to rigid or heat-resistant resins. The range represents different resin types; no single resin has all the highest ratings at once.

Benefits and recommendations

Advantages

  • Tough, flexible, heat-resistant and other specialist formulations.
  • Selected for the load and required behaviour of the part.

Good to know

An ‘ABS-like’ label does not mean the same composition as ABS filament. We consider the technical data sheet, correct curing and the operating environment.

UNDERSTANDING MATERIAL PROPERTIES

What does each rating tell you?

Ratings from 1 to 5 compare typical material behaviour. A higher rating is not always a better fit: a flexible protective part, for example, needs less stiffness than a bracket.

Printing cost
The relative cost of producing a comparable part. More stars mean more expensive printing. This includes preparation, production time and finishing, rather than just raw material cost.
Toughness
How well a material withstands impact and deformation before breaking. Important for holders, clips and parts that may be knocked or dropped.
Hardness
How well a surface resists indentation. For TPU, a Shore hardness rating helps describe how soft it feels.
Heat resistance
How it retains shape and useful properties when heated. We consider exposure time and mechanical load as well as temperature.
Stiffness
How far a part bends under force. A stiff material bends less, but is not necessarily more impact-resistant.
Wear resistance and environmental exposure
For moving parts, we assess sliding contact and wear. For outdoor use, we account for sunlight, moisture and chemicals; ASA is often a suitable choice for weather-exposed parts.
How do we use the scale?

Printing cost is a comparative rating: PLA has 1 star and nylon has 5. Stars are not a price list or an automatic quote. Actual pricing also depends on the part’s shape, size, quantity and finishing.

Property ratings simplify the comparison of typical formulations; they are not measurements of your part. Material formulation, moisture, print orientation and settings affect the result. For composites, FR materials and specialist resins, ranges show the differences between formulations. We check the properties of the specific material for your part.

You do not need to choose a material in advance.

Select “Advise me” in the form. We review every model individually and recommend a material, technology and settings for its actual use.

COLOUR AND SURFACE

Appearance is part of the brief.

Tell us which surfaces will be visible, the colour you want and whether the part needs to match an existing item. On-screen colours are a guide only.

Black
White
Grey
Blue
Red

Multiple colours, built into the print.

We can combine several colours in one part for logos, lettering, accents and distinctive branded products. We agree on the options based on the model, material and technology.

Availability depends on the material.

Engineering materials may not offer the same colours as PLA. Layers may be visible in translucent parts; translucent does not mean optically clear.

Finishing matters too.

We agree on support marks, sanding, painting and the desired finish before production. For precise colour matching, we can arrange a sample.

Unsure what to choose?

Describe the purpose, temperature, loads and environment in your enquiry. We will suggest a suitable approach.
