What’s the deal with 3.0 mm filament?Admin
MakeShaper is updating the way we label the diameter on our filament. Our “3.0 mm” filament will now be labeled 2.85 mm. We’ve always manufactured the “3.0mm” filament to a 2.85 mm specification, it’s just a change in the way we will label and refer to the product.
So… why did we call it 3 mm if it was 2.85 and why change it now?
Well, there are a lot of 3.0mm printers out there. That designation comes down to the size of their extruders and filament feeding tubes, which are exactly 3.0 mm (or the inner diameter is close to 3.0 mm). When using filament that is exactly 3.0 mm in a 3.0 mm printhead, expect some serious clogging issues, especially with a Bowden type extruder.
In the industry, most filaments labeled 3.0 mm are actually just slightly less in diameter to prevent this issue. We are extremely proud of our tight tolerances and are now updating our labels to match the true diameter of 2.85 mm. There are no changes to the actual filament.
