One Material – PA2200 Nylon, 2 Colours
At 3DPRINTUK we have chosen to specialise in one material, PA2200 Nylon. Why? The benefits of printing in nylon for our clients far outweigh other 3D printing technologies. These benefits include, surprising strength even at 1mm thick, low cost per cm3 and express production times.

Nylon PA2200 is widely regarded as the industry standard for high end 3D printing, yet still remains one of the most affordable, with prices starting from just 50p per model.
The material is both strong and smooth when combined with our free polishing service can be made even smoother – we say it’s like the difference between the texture of an Extra Strong Mint to that of a Softmint/Mentos.

The material is a brilliant white in its natural form, but can be dyed Carbon Black for an additional 10%
The natural surface finish is smooth, but has a powdery feel to it. This is comparable with an extra strong mint. With our free polishing service you get a far smoother finish for no extra cost – this is a finish comparable to a Soft Mint/Mentos.

We orient every part in a way that gives you the best possible result rather than the most efficient for our build. This means that we virtually eliminate the layers on the model. We use a layer blending technique that means that only the very near horizontal lines will show up on one side, we always make this side the bottom so you don’t have to see them.
You can see step lines on the roof of this model where the surface was not completely flat.
The official melting point is just above 170°C. From our personal experience we find that thin parts start to go slightly ‘floppy’ at just over 100°C whilst thicker ones stay stronger until nearer the melting point.
The Nylon can be both flexible when thin and rigid when thick. Keeping clips etc. to the minimum 1mm wall thickness will give them a lot of flexibility, but not a lot of strength. Thickening them up to 2mm-3mm will give great flexibility for that ‘snap shut’ strength, and upwards of 5mm will make the parts rigid.
The material is slightly porous.
Water – With water the porosity is relatively low, we tested a cup with a 1mm wall thickness and had no visual leaks or pools of water. We have had clients successfully use the material for underwater applications such as turbines, pipe connectors and valves.
Oils – We tested the same glass with standard kitchen sunflower oil. This went straight through in a matter of seconds.
Alcohols and solvents – not tested as of yet, but watch this space!
Petrol and Diesel – Petrol does manage to seep through the material, very slowly, but we would not recommend Nylon for any purpose where you require your prototype to contain petrol. Diesel reacts in a similar fashion but due to it’s higher level of oil it passes through the material quicker than Petrol does.
Based on our experience the material stands up to the test of time very well. We have some rugged camera mounts that fixed to the outside of a track day car that have been fixed there for 3 years and still holding strong.
No noticeable physical degradation has been observed to the properties of the part other than a slight yellowing of the colour. All our oldest samples still appear to have the strength they had when new.
How to get started
If you have a part in mind that needs reverse engineering or a sketch that needs designing please contact our design team. Still not sure if our prints can do the job? Give us a call and we’d be happy to talk you through your requirements. If we can’t help you we will probably know someone who can.
