Slice and compare multi-color prints: U1 vs Others

Spooky season is coming, but I just got spooked by the amount of gratuitous waste of perfectly good plastic by a certain “wanna be multi-material” approach.

Find the slight differences.

Process info: 0.16 mm, 15% adaptive cubic, 15mmX15mm prime tower (35x35 for the more conservative approach), tree supports

1st try, as suggested by the A1 mini default settings:


The waste is 7 times the actual object.

But we all know that those defaults are vastly “conservative” (wasteful), so here’s a more sensible approach for the 2nd try:


And we almost halve the waste with a 3.7 times the object weight in garbage.

For my 3rd trick, it’s now time to break out the nightly build and the U1:


We’re down to a 0.84 waste-to-product ratio, and we’re gonna have our object Today rather than Tomorrow.

And for the pogo-pins meme: with 1009 changes, you can print this thing at least 991 times before you’ll clearly break the bank changing those pins (3964 times is more realistic considering that the wear is spread across 4 sets of those pins).
With an 8.42€ in cost reduction due to saved waste, I’d like to ask @Jade how many pogo-pin sets we can buy just with what we’d save from this print :grin:

Nicely calculated. :+1:

The pogo pin quip :rofl:

And it’s no joke, mate. I’ve had more than one print where it’s a savings of half a kilogram. Half a spool wasted otherwise for just one print. And for those cases you’re talking about days versus hours to boot.

I ain’t got time for that.

You will not print when half spool would be wasted. Thats the difference. With multicolor you will solve problems which you would not have without it.

My opinion :wink:

This is accurate. I never bought any systems like that because of it. And now it’s solved more reasonably, so I can do things I didn’t before.

That is exactly what has been holding me back too and what made me instaback the U1. The amounts of waste were a real deterrent.

This is very true!
I got a BMCU for my A1 mini, and I haven’t used it for any “colorful” prints exactly because every time I just pass on the sheer time and material waste predicted by the slicer.

OK, I compared the U1 to a printer I could only dream about. Now I don’t dream about it anymore, because U1 changed the game.

My results for a 4-color Minion with supports:

  • U1: 4h 50min, 10.49g tower
  • Prusa XL with 5 toolheads: 7h 15min, 42.10g tower
  • Model creator: Jove

It’s really impressive that the U1 is able to print the same model in 2/3 of time the XL would need. Not to mention ease of use regarding filament loading (thanks to @Wombley for the great video explaining how this works)!

I wanted to try the Panda that came loaded with my A1, simple print.

I remember it took more than 4 hours for sure when i printed on A1.
But 70.31 g to 18.50 g filament use, that like 51 g of filament saving and most importantly 1/4 of time. Thats crazy
A1: Flushed 48.69 g Tower: 5.93 Model 15.70g and 4 hours 41 mins print time

U1: Flush: NA Tower 3 g Model 15.50 g and 1 hour print time. (That 2 secs Prepare time looks like bug in U1’s profile)

Used same filament for both.

We’re almost there! Thanks everyone for sharing your slicer screenshots. Just one more participant and I can let Jade know to get the giveaway ready. :grinning_face_with_smiling_eyes:

Ah, I miscounted! A draw happens for every 5 entries.

So excluding the first 5 screenshots, we actually have 7 new submissions. Once 3 more are submitted, I’ll remind Jade to draw 2 winners! Both rounds will be done together. :ok_hand:

whilst Master Cheeks will likely be printed at some point my daughter has expressed an interest in me printing this for her school. it is a cutout of the globe with all the different layers present and attaches together magnetically

https://makerworld.com/en/models/1120507-interactive-earth-model-with-layers#profileId-1118807

here is the main preview on the A1, i have collated the pieces together a bit better than in the original 3mf as there were 2/3 extra plates and this is how i would print it on the A1

on the A1 the globe on its own will take 26 hours and use 435g of filament

on the U1 the globe and inner core take 14 hours and use 379g.

The enitre print on the A1 will take 1 day and 6 hours and use 536g

The same print on the U1 will take 18 hours and use 512.31g.

Here is how i organised the plates for the U1

i appreciate that the savings arent massive as it isn’t a huge mulitcoloured print, but the time difference is noticeable. this is without being able to do any volumetric tweaks to the U1 which could further reduce the overall time

So who won the draw?

No draw yet, we’re waiting for a full ten submissions this time I think.

Just did a first very basic test to compare results with some parts of a Borderlands mask (Ripper Mask - Borderlands 4 by Borderlands | Download free STL model | Printables.com) and some added very basic color accents.

This is the result on a Bambu X1 with tree support: 150.78g of waste

And the same for the Snapmaker U1: 127.59g of waste: almost 15.4% less

And almost 30% less time required.

And this with only some simple color accents. Looking forward to actually see it in action (on a more colorfull example :slight_smile: )

(Sorry, can only upload 1 image)

I guess I will help along, with one more entry. Always wanted to try support material

Model: Cute Fox

For A1 with AMS lite

Print Time: 13 hours 55 mins

Filament used: 212.59 grams, Flushed: 152.93 grams, Tower: 27.79 grams, Support: 7.89 grams

For SM U1

Print Time: 2 hours 48 mins

Filament used: 42.40 grams, Flushed: NA Tower: 12.92 grams Support: 5.6 grams

So total, 11 hours and 170 grams filaments saved.

What I cant figure out why Bambu studio chose that support for the head, and other parts its still tree

I am sure this is 10th entry.

They got over 10, @Jade and @Sherry !

And I actually like that you shared something that’s only a modest gain. To be sure, the U1 isn’t going to make every print faster and much less wasteful, and that’s important to understand.

But when there’s just a ton of changes or coloring, boy can it make a difference! There’s stuff I can do on this thing I never would have bothered with before.

Haha, thanks @Wombley! I’ve already passed this on to Jade, and she should be arranging it sometime this week.
Thanks again to everyone for joining in! :smiling_face:
