EOS-P110-P100-3DPRINTUKOur Machines:


EOS P100 and P110

The EOS P100 is the leader of the pack when it comes to 3D printing. This machine produces nylon parts that are both strong and flexible. If you have seen 3D printed parts on the internet that are used in both practical or aesthetic applications, they’re probably built on one of these. This machine really is the answer to 90% of all the requirements, and it is the most affordable in our range too.

This machine fires lasers into a bed of powdered nylon, fusing it (sintering it), then sweeps another layer of powder on top and firing lasers at it again and so on until there are enough layers to complete the build. This support material acts as both build and support material and can be reused. This means that you can make big hollow items at little cost, as long as you leave a hole for the powder to escape from.


Nylon PA2200

Our Nylon material 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.



  • Working prototypes
  • Stronger parts
  • Larger parts (bigger than a fist)
  • Architectural Models
  • Complex Scale models
  • Medical parts

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.


In a nutshell, the machine is accurate to 0.1mm, but being a heat process, different models are affected in different ways.  Please see our page dedicated to the machine accuracy.

Melting point

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.

Elemental Degradation

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.

UV Degradation

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.


When polishing parts that have a tapered edge or unsupported walls, under 1mm, please be aware that it is highly likely that the part will be damaged during the vibro-polishing process. Unless it’s absolutely necessary to take this risk, we would advise not to polish that part. We recommend you thicken walls/end of the taper to a minimum of 1.5mm but we cannot guarantee that anything will survive below 2mm.

Minimums and Maximums

Maximum build size

Our current maximum bed size is 300x230x190mm – illustrated to the right. This maximum doesn’t mean to say that we can’t print your model if it’s larger so do still enquire.

Minimum Wall Thickness

We have a minimum wall thickness of 1mm for parts guaranteed. We will print things thinner than 1mm, but it is at your own risk. If these break in our hands, your hands or the hands of the postman, or lost during the cleaning process, it will not be covered.

Minimum Surface Detail

If you have embossed or engraved details such as logo’s or artwork, we have minimum guaranteed surface detail of 0.4mm. It is likely that items will be visible if they are less than this, but we cannot guarantee clarity below that.
