what's the deal with 2.85mm vs. 3mm?

Recommended Posts

I stopped by the Inside 3D Printing Conference today in NYC and was talking with the guys from Ninja Flex. They sell a very flexible filament in both 1.75mm and 3mm sizes. I asked if their 3mm size was true 3mm or 2.85mm with a tolerance up to 3mm. They said they never heard of the 2.85mm standard and as far as they know their filament is true 3mm. How common is 2.85 and is it going to be supported by filament makers going forward?

90% of filament that claims it is 3mm is actually 2.85mm or 2.9mm. The remaining 10% that are truly at 3.00mm are a problem for the UM and can't be used. Don't even try it. Most of these manufacturers get enough feedback that within a few years they figure out that they should be making slightly smaller filament.

Just because an employee doesn't know about this, doesn't mean the company itself is also ignorant about this.

    • "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.
