NPD (New Printer Day!)
This is a delayed post, but a few weeks ago
@loganb forced my hand into buying another 3d printer when my current one was working perfectly fine
Those following along for awhile might remember my printer trajectory:
Creality Ender 3v2 = lot's of issues, replacement parts, frustration. When it worked it worked, when it didn't it was maddening
Creality Ender 3 S1 = much better reliability, direct extrusion, no clogs... but bed leveling didn't work and I had some 1st layer issues, some stringing issues, and top layer issues, especially on larger parts. Custom firmware took care of the bed leveling, and it's mostly been good, but not perfection.
So that leaves us with my newest printer, the Bambu Labs A1 + AMS Lite:
At first glance it looks pretty similar to the Enders... it's a bed slinger, open air chassis, similar size.
So why upgrade? What makes it so much better? These were genuine questions I had. Well, turns out a lot.
First off, the packaging, instructions, and
design are excellent. It was so easy to assemble, and it is very well thought out. Not just for ease of assembly, but alignment, dust protection, the way the cords interface. It all feels premium and substantial. Just holding the parts in my hand I already had more confidence in it.
Other points:
— It doesn't use the stupid plastic/rubber V-wheels from the Ender
— The X-axis has a linear rail
— There is no play in any of the axis
— No stupid bed leveling wheels to mess with
— The build plate is actually flat
— The PEI sheet is way nicer than the Creality one, and it's self-aligning
— It has an extrusion indicator wheel so you can see what the extruder is doing
— The fan ducts are designed in a way that you can actually see the nozzle when printing (unlike the S1)
— Much nicer touch screen
— It's more aesthetically pleasing with it's filleted plastic shrouds and white color
— It can do multicolor printing with the AMS!
— Speed!!!
When first booted, it did a self-calibration sequence, including a bed level, and tuning the motor frequencies to make them as quiet as possible. You can do your first print without doing any manual calibration. No leveling, no Z-offset bull
The screen always tells you what's going on, and if there is an error, it has a descriptive error assistant that so far, has been 100% spot on.
The first thing I printed was a 15 min Benchy off the SD card it came with, and it looked fantastic. As good as any of my Enders, but twice at fast. I'm not used to these speeds so watching it go was a bit surprising.
Oh yeah, and the screen always shows an image of what you're printing. Neat-O.
The slicer can calibrate flow for the filament you're using before the print. And the purge line is better. And it has a little rubber pad that it cleans the nozzle of drips right before the print starts.
With the AMS... the filament loads and unloads itself into the extruder. So cool.
I could go on and on.
Next I printing some modular wrench organizers to continue my wrench drawer. I thought about a custom Fusion 360 design, but didn't feel like the effort. This worked out fine.
Came out beautiful, and the PEI sheet leaves a lovely texture on the bottom.
In the drawer (the offset wrenches)
I also dove head first into Bambu Studio slicer, moving away from Cura. Bambu Studio is easy, well-laid out, has some features Cura doesn't (to my knowledge), and works perfectly with the A1 since it has provisions for the AMS system and multi-color printing.
This would be a good time to mention the Bambu Handy iOS companion app is... great!!
Multicolor Prints
Multicolor prints are pretty wasteful depending on the model, so apparently every Bambu user needs a "poop bin" to collect the color change poops it makes.
I found a model I liked and it printed beautifully.
Loading the AMS is pretty easy. There are motors that automatically grab the filament as you feed it in. And it has a library of filaments. I was able to find most of what I had (Overture and eSun PLA). Otherwise there are generic settings for different materials. You can configure right from the printer touch screen, or in Bambu Studio.
I happened to have these colors, so I did my first multi-color print...
these friendly ghosts for the kids!
Feeling Halloween-y, then I made these
tea light ghosts:
And then probably the. most impressive print to me so far, a print-in-place storage box for the A1 accessories.
It came with this thin plastic tray:
And I printed this:
Shout out to the creator for this awesome design. The bottom and top are nicely textured, multicolor was clean, and all the details came out perfect.
Needless to say I'm over the moon with it. Not that I doubted, but know I know why everyone raves about Bambu Labs. It's not *just* the print quality, because let's be honest there are plenty of printers that can do a good job. Even my S1 was pretty damn good most of the time. But it's the total package... the software, the hardware, the ease-of-use (almost everything is automated), the multicolor capability. I don't feel the need to babysit the start of a print at all.
I'll add a long term update after I've had it for longer. But now I need to figure out what to do with my Ender 3 S1. Because I don't really see myself going back to it.
