Greetings 3d printer X-spurts;
So I've come to the conclusion that quite a bit of what you can
download
as .stl's, are intended to be very low resolution so as not to compete
with the same you-toobers commercial offerings.
I don't know if that is the reason, but I have certainly found that only
a small percentage of the Thingiverse stls are worth using. That's
mostly because I have issues with the design of the parts, rather than
the printed output, but your thought adds an interesting dimension to
the argument. I don't know how print quality is related to an stl file,
becuase I had assumed most of the quality of interpretation lies in the
slicer. But maybe not.
What nozzle size and layer thickness did you use? I assume it was much
the same as for the harmonic drive, but I certainly find the difference
between, say, o.2mm and 0.1mm layer height makes a huge difference to
the quality. I tend to stick with 0.4mm nozzle size, but I know from
friends that a move to a smaller nozzle can improve quality even further
- even if print times do become rather extended for larger jobs.
I am using a cheap Anet A8 printer, which is essentially a copy of the
Ender i3.
And my printer isn't
the piece of crap I turned off in disgust 6 weeks back. I am
impressed.
No; low price does not necessarily mean low quality prints. It does mean
the printer will probably require some fettling and mollycoddling to
give of its best, but there are no surprises there.
I note that the recent models of the Anet and Ender feature more rigid
metal frames (Anet is plastic) - although they are still a bit flimsy if
you ask me.
As with machine tools, rigidity is (nearly) everything.
