The only nozzle series you need!

As you know our goal at Emvio Engineering is not to shift boxes. We want to stock unique and value adding items. This is the reason why we are now working with Olsson Ruby to bring the most hardwearing nozzle to the UK!

The Olsson Ruby is an invention by Anders Olsson, the man that gave the Ultimaker community the Olsson Block. The back story of the Olsson Ruby is one that has inspired us and as one member of our team is well versed in hard metals and materials, it really hit home how elegant the nozzle is.

The Olsson Ruby consists of a precision machined threaded brass body and a perfectly ground ruby tip. Rubies, being aluminium oxide, is extremely hard wearing but unlike some of the other ceramic equivalents has a better thermal conductivity. Best of all, the processes involved in machining it have been established for centuries. Ruby is the watchmakers hard material of choice for jewel bearings after all.

Take a look at the results of tests conducted with carbon filled filament:

Sigma nozzle extruded 0.3kg
Sigma nozzle extruded 0.3kg of filament before being so worn
A stainless nozzle lasted on 1kg
Common misconception - Stainless does not mean hard. This one lasted only 1kg of CF filament
Hardened steel lasted on 4kg
The classic hardened steel nozzles fared ok extruding 4kg of carbon filled

Here is a testimonial from one of our friends and customer Darren K, as posted on Olssonruby.com.  (Darren also purchased a full set of upgrades for his BCN3D Sigma.)

First, I tried a few hardened nozzles and I had thermal issues. I also did try steel but it was like putting my finger in the air to find new standard print parameters each time.

Now, I use the Olsson Ruby and I’m a big fan.The main benefit for it is that i don’t have to worry about a moving target. Once I have things dialed in for the nozzle diameter, that’s where it’ll stay. Normal brass is a variable as it gets worn down and over time that is troublesome when creating parts that have very specific fit qualities.”Darren Keirle, UK, Feb 28th, 2017
