Ultimaker S5 Nozzle cleaning

Recommended Posts

Hello Makers of the Ultiverse,

 

I am using a S5 Printer for my work. After a couple of printings, the BB print core with
the PVA is on the outside of the nozzle black. It Looks a bit burned of the filament or some
dirt of the black tough PLA. I dont know. For this, I want to clean the nozzle. Do you
have some instructions how to clean it? Cotton swab with acetone maybe?

I haven't used PVA that much, but if you want it to look a bit nicer, an easy thing to do is get a scalpel, or sharp blade and simply trim it off carefully, like shaving, obviously not cutting into the nozzle itself, should take you less than 10 seconds. I tend to hold the blade in my fingers rather than attaching it to the holder as it has less power that way. I tend to scrape any nozzle that looks like its building up an outer shell of pla, or whatever. Don't scrape the bottom though, just the sides. I've done that on my old UM2 for three years straight and had zero issues. Nozzle still looks like new.

      Q: For some users, abrasive materials may be a new subject matter. Can you explain what it is that makes a material abrasive when you are not sure which print core to use?
      A: Materials which are hard in a solid piece (like metals, ceramics and carbon fibers) will generally also wear down the nozzle. In general one should assume...

    • "Back To The Future" using Generative Design & Investment Casting
      Designing for light-weight parts is becoming more important, and I’m a firm believer in the need to produce lighter weight, less over-engineered parts for the future. This is for sustainability reasons because we need to be using less raw materials and, in things like transportation, it impacts the energy usage of the product during it’s service life.
