Having billed out a couple of big-ish jobs and sold the bike, I had a couple of spare bucks and splurged on a new 3D printer.

The Creality Ender V2 has been a peach and I've learned a lot, but it's slooooooowwwww. I downloaded a project and sliced it for the Creality and the projected print time was over 12 hours. Even with "hit print and forget about it" that's a bit much. Plus, like everything else, technology has improved and prices have dropped over the last few years, so I figured what the hey.

My new Bambu Labs A1 showed up today, a half hour assembling and another half hour while it did it's self calibration and I'm off to the races. The aforementioned project should take about 2.5 hours.

A raft of nice features including automatic bed leveling, wireless connection to my computer so I can send project directly instead of copying to a mini-SD, the ability to monitor prints via my cell phone and a few other geeky things. The calibration sequence included noise canceling for the servos that run the x,y and z axis plus filament feeder, anti-vibration by looking for and canceling harmonics between the 4 servos. Very cool! Oh, and if I buy the attachment, it can also print in up to 4 colors, switching automatically as needed. I think that'll likely happen eventually.

The Creality will go to my daughter as she desperately needs another hobby:laughing:
 
I took an intro to engineering course as part of one of my Associate's, we had to design a little children's toy using Fusion360.

I was essentially able to 3D print an entire chopper as an assembly, with moving front and rear wheels and pivoting forks because one of the filaments was a dissolvable support filament. The printer at the college automatically switched between the structural filament and the support filament, and when the part was done it was soaked in some solution to dissolve the support filament, leaving behind a fully assembled chopper.
