Thing-O-Matic: Graduation Day

OK, so I printed a Stanford Bunny to haul along to the 3rd Ward Make-A-Thon:

It’s one of the few objects I’ve printed with enough interior to show the honeycomb fill pattern:

Obviously, this was before I sawed three segments off the LED ring light.

It had a bit of trouble with overhang under the ears, but I figure rabbits are soft and fluffy there anyway, so I’ll define this as a feature rather than a bug:

What’s nice: all I did was slice the STL and build the rabbit. No muss, no fuss: It. Just. Works.

Some parameters:

• 0.33 mm thickness, w/t=2.0 -> 0.66 mm width
• 50 mm/s print, 75 mm/s move
• Reversal 25 rpm, 75 ms, early action

An organic object like this eliminates any problems with waviness due to axis instability.

If you look very closely, you can see early Reversal suckouts just to the left of the zit marking the start of the thread. This was the object that prompted me to turn off early Reversal action, but I still haven’t figured out how to get rid of the zits:

(Is it just me or does that not look like part of a rabbit?)

All in all, though, this bunny marks the end of the Intense Thing-O-Matic Hackage era. The printer now works dependably, prints parts accurately, and doesn’t require a lot of babysitting. I’ll present some test pieces over the next few days that explore some variations.

While I didn’t quite jump & clap my hands, life is good…
