Can we talk about bottoms for a while?

By which you should know I mean the underside of prints…sigh …if you’re here for any other reason I despair…

Getting a good top finish is easy these days…and getting a good underside too - gloss or that nice PEI texture if you’re on either glass or the build plate.

But anything in contact with support (shudder) or worse still, completely unsupported has always been a loopy, stringy, dog-rough nightmare.

Until now. For reasons I wont’ bore you with (yet) I wanted a box section, 40mmx40mm, with a 2mm wall, floor and roof; effectively a 40mm square pipe.

And The K2 Plus just…did it. I mean granted it’s the worst of all four horizontal surfaces created…but…I’d have danced a little jig to get that sort of finish on a 20mm bridge on my old CR10s Pro (using Cura).

My question is; is the improvement (the VAST improvement) due mostly to hardware (the new K2), software (the Creality Slicer) or materials (Hyper PLA)?

Hello GreyArea,

For no support, that is quite amazing,

Cheers.

It’s fascinating to watch it do it (real time; the time lapse doesn’t do it justice because it’s over in a flash). Like some sort of spider weaving it’s web. I’ll be honest, you get slightly better results if you add tree support - even if it’s just on “touching buildplate”. The trees support the first few lines of the bridge, and make it far less loopy. Still, as you say, for 40mm unsupported printing this is quite a good result.
