Prototyping materials
We stock a wide range of prototyping materials including multiple grades of thermoplastics and metals.
Our aim is to provide you with the right combination of technology and material to simulate the properties you require from your finished part, whether it be for display and presentation or fit, form and functional testing.
What should you consider when choosing a prototyping material?
- Mechanical properties
- Manufacturing characteristics
- Appearance
- Cost
We can advise on material selection for every prototyping technology.
We offer materials to fulfil a wide range of properties and characteristics, from specialist temperature resistance to materials certified as bio-compatible for use with medical or dental products. Other materials supplied include those certified ‘food safe’ meaning they can be used for storage of food or drink.
What mechanical properties are required of the prototyping material?
The main factors determining material choice include mechanical characteristics such as stress, heat resistance and elasticity of the part.
Here are the most common factors:
- Strength
- Elasticity
- Hardness
- Durability
- Temperature resistance
- Transparency
- Moisture resistance
- Impact resistance
Other factors to consider in material choice include the material’s suitability for manufacturing and how close to the actual material the prototyping material is.
Please note, these are general guidelines. In all cases if you do not find a material you are looking for or need guidance, please contact us. We are always happy to help.
