1.75 mm vs 2.85mm filament
TRANSCRIPT
Filament
“3D Printing community brought up different filament diameters form 1.75mm and 2.85mm or 3mm to use for their projects”
History
• Plastic welding filament• matching the technical requirements of 3D printing• used frequently because it was available• most often came in 3.00mm diameter size
• 3D Printing with filament• Many 3D printers of several years ago used 3mm plastic filament only.
1.75 mm Filament
“A few short years ago we started
seeing the emergence of 1.75mm
filament”

1.75 mm filament
You get more control and precision
3.0 mm filament.
faster build
1.75 mm filament has the following advantages over 3 mm filament.
Finer control over the amount of filament extruded.
Less force required to push filament through.
With smaller area, less force is required to achieve the same pressure within the hot end. Gear reduction is not required to increase torque, like on 3 mm extruders.
This makes the extruder cold end simpler, lighter, and more compact.
Faster possible flow rate
1.75 mm filament has the following advantages over 3 mm filament.
It may seem counterintuitive, but 3 mm filament is actually not better for faster privolume ratio, making it easier to pump more heat into it more quickly.
No confusion over diameter standards. "1.75 mm" filament actually is 1.75 mm nominal. "3 mm" filament may actually be either 3.00 mm or 2.85 mm nominal.
Some machines (like the Ultimakers and Airwolfs), are designed for 2.85 mm filament and will have trouble with 3.00 mm.
3 mm filament has one important advantage over 1.75, though. It is much easier to run 3 mm flexible filaments in extruders that are not specifically designed for them. The fatter filament is less prone to buckling.
nting. This is due to the fact that smaller filament has a larger surface area to
Depending on the machine, you might have to consider adjusting or changing the following components:
• Hot End
• Filament feeder (including Bowden, if your not using a direct feeder)
• Filament settings in Matter Control
• Firmware and/or EPROM settings.
