3D printed DD rotary from Norway!

Printing at higher resolution makes the whole print stronger and easier to work with. The lower the resolution the more chances you have to get split layers especially when applying force to the part. Looking good man.

Thanks!

Yep, I know, right now I´m printing with 0.25mm layer and have a 0.45mm nozzle, and with a bit higher flow, lower speed and right amount of cooling it works good, no splitting vice etc.
PLA is easier to work with that way, you can see a bad print right away, that will split.
I´ve done some stresstesting on some of my prototypes, with force, and 6months with tattooing, and that was before I got my printer running optimal. The frames are printed with solid overlapping infill and 1.35mm wall.

Solid Infills is the way to go. these guys may take a long time to print but they'll be worth it.
Have you tried acetone to give the printing a smooth finish. If you do it right it may look like you tumbled the part and polished it.

I've noticed that the different colors have different strength and finish.

Actually I´m printing in PLA, as in the name of the machine "PLA-stik"
And acetone doesn´t bite on PLA as it does on ABS, there is something else that is used, but I can´t remember the name and have no idea where to get it.
ABS react to several chemicals, but PLA seems to take almost anything, except too much head i.e boiling hot water.
IMO the PLA is better as material for this kind of construction, its harder and its easier to post-process, ABS tend to softly bend and finally break. And of course, there is the handmade-feel to it that matters to me, 3D printing is kinda like molding brass/steel frames for coil-machines, you have to do something to it afterwards..

Yes, different colours have different strength, I find the solid ones the best and easiest to print/process.. The transparent ones can be a pain in the ass sometimes.
