Filament Size

Recommended Posts

Are there any plans to produce 1.75 mm filaments? I have two printers (UM3 & Raise3d N2 Plus) and have tried using PVA in both. The Ultimaker PVA works like a dream. The non-Ultimaker PVA not so much. I think it would be great if I could use UM PVA on my other machine, but it takes the smaller fillament size.

Seeing all UM printers use 2.85mm filament I don't think they will start to produce filaments of other sizes until they start selling printers that use 1.75mm.

UM have said in the passed that they won't rule out making a printer that uses 1.75mm, Maybe UM4? who knows. Things change and they may decide to just stick with 2.85. This would be a few years away I think anyway.

Did you use the UM PVA in the raise??

It probably prints like a dream in the UM3 because it has been finely tuned to work in the UM3 but you may find if it was used in the raise it wouldn't be as good.

There are a lot of other manufacturers that are now making dissolvable support filaments. I have heard some good reports from e3d scaffold but never tried it. Most companies give out samples so it may be a good option to try as many as you can.

UM filament won't fit in the Raise (1.75). I do have Scaffold and Edge coming as well as a sample if rigid ink (E3D doesn't have samples). Hopefully one will work. I don't really want to switch to ABS.

    • "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.
