3D Printer Filament 1 75mm 3mm

User rating: 3.9/5There's no appreciable difference. Just use the filament that fits your particular printer. If you don't yet have a printer, then I'd get one that uses 1.75 mm filament: 1.75 mm is increasingly becoming the "standard", thus being easier to get. Some filaments are not available as 3 mm.Best answer · 24There are a few factors to consider those two: 3 mm. More rigid - easier to print with flexible plastics. I couldn't make my 1.75 mm printer print with NinjaFlex using standard bowden extruder. Can extrude faster. Quality is less affected by changes in diameter - it is a concern mostly when using cheap plastics. 1.75 mm. 16I generally agree with the points in masteusz's and Tom van der Zanden's answers, but I would add a bit more detail. Generally, the differences are minimal, however: Generally speaking, a 1.75 mm filament will make it easier to use a smaller nozzle diameter (<0.4 mm), allowing for more precise prints in some cases.12I think (as do a lot of others) that the differences are rather minor. So just my 2 things I know from experience. We've been using 3 mm for some years and now we are moving towards 1.75. 1.75 mm filament is very easy to entangle, especially, if it is not on spool. You can even easily create knots on the filament and it is very hard to untangle.10As I read the history, 3mm filament was an accident of the supply chain when 3D filament printers were first being developed by hobbyists. There was a product called a "plastic welder" which consisted of a melting device and a source of filler material. This filler was 3mm plastic.2I agree with all the answers above but only would like to add if you want to build a very large printer using 0.8mm or 1.2 mm nozzle, i would advice to go 3mm. 1.75mm filament then just can't be fed in fast enough.1One thing I haven't seen anyone mention yet is the issue of the size vis-a-vis time of the final print. 3mm filament allows the printer to spit out a lot of plastic at once, letting you build must taller prints much faster.1
