We have compiled a guide with instructions and ”do’s and don’ts” for using The Olsson Ruby nozzle which you can find on our support webpage using the below button.
Improvement suggestions are always welcome, let us know via email at email@example.com
The Olsson Ruby, installed on an Ultimaker 2+
Frequently asked questions
What is the Olsson Ruby?
It’s a unique nozzle for 3D Printers, designed to print highly abrasive materials while retaining the excellent heat conductivity of brass. It works equally well for printing common FDM / FFF 3D printing materials.
What is the benefit compared to standard brass nozzles?
The tip of the nozzle consists of a ruby gemstone – technically Aluminum Oxide – which is a very hard material.
This means that it is very durable even when printing exotic materials containing abrasive materials. See list of tested materials.
Some people have also seen an improved surface finish with the ruby tip (compared to pure brass).
Are there any downsides compared to a standard brass nozzle?
So far, we have only seen benefits. Join the discussion on the Internet forums.
What is the benefit compared to stainless steel or other, coated, nozzles?
Since the base material is still brass – which has an outstanding heat conductivity – the Olsson Ruby has a big advantage to most other materials (for example stainless steel). Also, the tip is made out of ruby which is very hard and durable. We believe that nozzle designs with different coatings will wear off quite quickly when continuously printing/grinding towards an abrasive material (the model being printed).
We have designed The Olsson Ruby to be compatible with the popular form factor of a nozzle with a 7.5mm long M6x1 external threading, like the range of Olsson Nozzles used on the Olsson Block for the Ultimaker 2, and on the E3D hotends. This list is compiled
both of the printers we have tested and some we believe will be compatible from looking at specifications.

Prusa Research i3 MK2
gCreate gMax 1.5XT+
Makerbot Replicator 2/2X *4
Felix Pro 2 * 4
Raise3D N1/N2 *5
*1 = You will need to adjust the fan shroud since the nozzle is shorter than the original nozzle.
*2 = You will need to mount it with the nozzle not placed against the front face of the heater block but against the heat break/isolator tube to create a seal.
*3 = Will require disabling of the automatic bed leveling since the ruby tip is not conductive.
*4 = Several testers reports success
*5 = Adjustment of z-stop required, also see notes on the revision of your Raise3D printer in the Instructions for use
What materials can I print with the Olsson Ruby?
You should be able to print with any material you normally print with a standard brass nozzle, but with the benefit of lasting longer when printing abrasive materials. It has been tested by many (50+) beta testers alll over the world with a lot of different materials, including:
Carbon filled (Colorfabb XT-CF20, Formfutura CarbonFil and other brands)
Metal filled (Colorfabb SteelFill, Brassfill, Copperfill)
Boron Carbide-filled ABS
(As always, your particular 3D Printer, material and slicer settings used will play the biggest part in the result, regardless of the nozzle type)
What models/sizes are the Olsson ruby available in?
1.75mm filament / 0.4 diameter: Available February 2017
2.85mm filament / 0.4 diameter
We have several models/sizes planned, however doing test iterations with new ruby nozzle geometries is affected by quite long lead times due to the complex manufacturing process. It helps us to prioritize if you submit your interest in the model/size you are most interested in as per below.
