Who are the creators of The Olsson Line?

The Olsson Line was born from a collaboration between Swedish research engineer Anders Olsson from Uppsala University and the team at 3DVerkstan, Sweden's leading solutions provider within additive manufacturing and 3D-printing. You can read all about it here, in our stories. The Olsson Line provides optimal solutions to real life requirements, bringing your print results to the next level.

The Olsson Nozzles

What is the Olsson Ruby?

Is a unique range of nozzles for 3D printers. Classic options include V6 and MK8-style nozzles, suiting a wide range of printers.

See Compatibility

The Olsson Ruby is also available in High Temp.  (up to 500c) and High Output versions with a longer thread.



Each nozzle Olsson Ruby contains a real ruby ​​gemstone (technically aluminum oxide) which is a very hard material that protects it from erosion by even the most highly abrasive 3D printing filaments. 
See Materials List

The ruby ​​does not wear off overtime as with coatings on alternative products.


The ruby is set into the tip of a brass or copper alloy nozzle, which enables its excellent heat conductivity.

This sets is apart from alternatives such as stainless steel and hardened steel which do suffer from lower heat-conductivity when compared to copper alloys/ brass.

All of this adds up to extremely accurate and efficient prints,

 across virtually any printable material, and a nozzle that will last a lifetime.

How does the wear compare?

We tested various nozzles by printing carbon fiber filament, known for its extremely abrasive qualities, here are the results:


Brass after 0.3kg


Stainless steel after 1kg


Hardened steel after 4kg


The Olsson Ruby after 8kg of carbon fiber filament showed no wear, even under a microscope.


What is the benefit compared to standard brass nozzles?

Standard brass nozzles have fantastic heat-transfer properties but are affected by the material passing through them. Abrasive materials such as carbon-fiber composites wear at the nozzle diameter and shape of the tip. Filament can also harden on the outside of the nozzle changing the shape and disturbing your print and damaging your finish. This is especially noticeable with "messy" filaments such as PETG.

For abrasive filaments we recommend using The Olsson Ruby Nozzle and for cleaner prints with a sharp finish we recommend Olsson Precision Nozzles. Aside from their non-stick coating Olsson Precision Nozzles are hardened and can be used for occasional printing of exotic filaments. The High Temp version of The Olsson Ruby Nozzle combines the benefits of both. See our list of tested materials below.

As always, your particular 3D Printer, material and slicer settings used will play the biggest part in the result, regardless of the nozzle type. In some cases it is advisable to increase printing temperature 5-10C depending on material and type.

Will an Olsson Ruby work on my machine?

We have multiple versions of the Olsson Ruby nozzle that suit  a very broad range of 3D printers, see the list below.

What is the maximum operating temperature for the nozzles?

The Olsson Ruby, MK8, High Output and Precision Nozzle each have a maximum operating temperature of 300˚C.

The Olsson Ruby High Temp, however, is able to reach 500˚C.

It’s made up of a copper alloy with a high-performance, non-stick chromium nitride coating that results in smoother, cleaner prints.

How do I use The Olsson Nozzle tool?

First heat your nozzle to the print temperature of material being used. Turn counter-clockwise to remove your nozzle, clockwise to attach it. The Olsson Nozzle Tool will automatically limit the force applied thus preventing you from overtightening.
Only ever change your nozzle hot.

Is my printer compatible with The Olsson Nozzle tool?

Most 3D Printers use a (7mm) hex shaped nozzle which fits the Olsson Nozzle Tool perfectly.

Who is the Olsson Block kit for?

Owners of Ultimaker 2 or 2 Extended printers who wish to have the same flexibility in choosing their own nozzles as Ultimaker 2+ owners. The Olsson Block Kit includes tools for installing The Olsson Block and Olsson Brass Nozzles at .25, .4, .6 and .8mm.

How do I install the Olsson block kit?
