What is the difference between a printer that prints 2…85 vs. 1.75 spools of filament.

What are the advantages / disadvantages?

I know that they both can use about the same size diameter nozzle.

Why choose a printer that prints 2.85 over 1.75?

2.85 IS STONGER AND STOPS ANY FLEX IN THE BOWDEN TUBE . THIS IN TURN MADE FEEDING THE FILAMENT TO THE EXTRUDER SMOOTHER

So the 2.85 doesn’t print faster or anything the only advantage is want you said above?

Thanks from the link! Whats the deal with running 1.75 on a 3.00 machine? I have read in a few you can do this

Where are you located? Being in New Zealand myself, my choices are limited to 3mm.

1.75mm filament is available but at 3x the cost of 3mm so it is worth checking availability and pricing in your area. I run 3mm filament on everything.

If you’re going to get a delta printer with a bowden tube then 1.75mm has the edge. 3mm exerts a fair bit of force making it uncoil, which can cause your end effector to flex and move around a little. Since then there has been an upcoming trend to make suspended extruders (also known as floating extruder mod) which work around these downsides. It is almost as good as direct drive on a delta (so in short, fantastic), I’m running that with 3mm filament and it works great!
