Got a Bambu P1S but the build are low quality (lemmy.world)

Hey guys I got the bambu P1S a couple months ago because it was recommended. I'm super new to 3d printing. This is my first one. I'm not new to electronics or computers. I ran a few of the built in prints, a dinosaur puzzle and this scraping tool but both came out fuzzy and in poor build shape. What can cause this? Shaky table? Cold temps (the printer is in my insulated garage getting around 65 degrees at the moment inside)? Is the stock bed bad? The filament it came with bad?

Thanks for any advice.

Is that white filament the one that came with it? If it is, it is only meant as support material. Use the orange or green in AMS slot one and try again.

[–] Aermis 30 points 5 months ago (1 children)

Wow I think you're right. The bag even said something along the lines "this isn't filament" and I'm like uh. It looks like filament. I'm an idiot.

[–] [email protected] 18 points 5 months ago (1 children)

It's ok, my dude. We all make simple mistakes like this. I've cost myself entire rolls of filament before. If you ever have any questions, give me a shout, I'll give you a hand.

[–] Aermis 7 points 5 months ago (1 children)

Wow thank you. I'm home now, and I'll swap the white one out for one of the other ones and see how that fares in making a print or 2. What do I do with the white one? Put it in the last slot? Does the machine know when to use the white one as a support?

What would you consider is your favorite filament to work with? I'm thinking of splurging on a set off ebay. But at the same time, are discount filaments ok?

And do you use a special plate? People have mentioned golden ones that are easier to bend to pop out the build? Mine just scraped off fairly easy. And I've read to use hairspray or windex to make it easier to pop off later.

I'm sorry I'm asking a lot. I get a hang of things pretty quickly haha, so once I'm going on a system of what to buy and how to install it I'll be good to go.

No, no. I offered assistance.

What do I do with the white one? Put it in the last slot? Does the machine know when to use the white one as a support?

I don't use the support filament as I have enough filament that using a bit for a model or two here or there isn't a huge loss. However, you can use the Bambu Studio program and "paint" the support structures with that filament and it will use that instead of whatever normal filament you are using.

(Note on this, because these machines use NFC for the official bambu filaments, it might do it automatically. Don't count on that though and always double check.)

You can keep it in your AMS anywhere you like, but for those onboard print files, it typically uses AMS slot one.

What would you consider is your favorite filament to work with? I’m thinking of splurging on a set off ebay. But at the same time, are discount filaments ok?

I love Inland filaments because I'm close to a Microcenter and can go and physically look at them before purchasing them. If you aren't close to a Microcenter though, Inland filaments are Polymaker and eSun.

If you plan to get cheap filament, make sure you keep your bed as clean as you can because you want to rule that out immediately if there is an issue. I use Isopropyl alcohol before every print to remove any grease/oil/dust from the bed.

And do you use a special plate? People have mentioned golden ones that are easier to bend to pop out the build? Mine just scraped off fairly easy. And I’ve read to use hairspray or windex to make it easier to pop off later.

I use the standard PEI plate that comes with the machine. I allow the bed to cool off in the machine and then get the print off. Makes it much easier.

Controlling these printers is best done from a PC. Bambu Studio will give you the most options to control your prints. The Bambu Handy app works great as well but I find it limiting.

Thank you so much for this information! Sorry I respond so late. Its been very busy and I haven't had time to get on lemmy.

Before I read this I went ahead and booted up bluebeam studio and got familiar with it. Did some research and got a high temp plate just in case the PEI standard plate the machine came with won't work with PLA+/PETG. I'll eventually want to be able to print robust parts as components.

Then I used up my ebay gift cards and got esun and sunlu on huge sales (there's like 3 different discounts going right now). Got 17 PLA spools in all sorts of colors including wood, marble and even 2 glow in the dark ones (red and blue) for less than $200. 1kg. I don't think they're cheap, since regular price averaged around $20/spool, 30 for the glow ones.

I won't use structure either. I heard it's not necessary. I'm doing my first custom build (kind of, just modified off an existing build) of couple deck cases with the orange/green I have. I already did a couple other runs on the green and that solved the issue with fuzzy cheap builds. I was using the wrong filament. So now I'm excited what I can come up with!

Thank you for setting me on the right path.

[–] [email protected] 1 points 5 months ago (1 children)

Well support structure will be needed on overhangs and stuff like that so don't write it off.

I don't use it much since I'm mostly printing things that don't need it as they were designed to print in place.

[–] Aermis 1 points 5 months ago (1 children)

Oh I see! OK yeah I'll keep it for when I need it. But it doesn't seem like I'll need a lot of it so I'll keep it to the spool I got.

[–] [email protected] 2 points 5 months ago* (last edited 5 months ago) (1 children)

Kept forgetting to tell you, you will want this for your ams and I use these for dryboxes. You can just grab some totes from the dollar tree or somewhere cheap and throw those in with the filament. Quick and easy way to keep your filament dry.

Here's a hygrometer stand of the same type so you can keep it uniform.

Fill them with this stuff here.

Make sure it's the rechargeable kind so you can just keep redrying it and you'll never run out.

This is all especially important if you plan on printing PETG. PETG is affected much more by moisture than PLA.

[–] Aermis 2 points 5 months ago

Wow I would have went through so much trouble trying to figure out my problems before stumbling on moisture problems. Especially since I'm printing in my garage.

Thank you so much for bringing this to my attention before I ran into many problems. I didn't even think about how I'm going to store all my filament. I was just going to go loose on the bottom of my table in a container.

It's interesting that the instructions for preparing the AMS had me take out the dessicant from the 2 trays in the roller area. I was wondering what the point of these being empty was. I'll fill that with back up with dessicant.

[–] [email protected] 7 points 5 months ago

Damn fine callout here, it definitely looks like the AMS there is loaded up with the green, orange, and pla support

[–] [email protected] 3 points 5 months ago (1 children)

Is the white one a different material then? PVA?

[–] [email protected] 5 points 5 months ago* (last edited 5 months ago)

~~Not sure, I've never opened mine.~~

This is it here: https://us.store.bambulab.com/products/support-for-pla?variant=40524454723720

TDS says it's still PLA.

[–] Linecutter 3 points 5 months ago (2 children)

Have you done any calibration, or just gone straight to printing?

[–] [email protected] 3 points 5 months ago

These printers calibrate themselves.

[–] Aermis 2 points 5 months ago

Yeah what mihnt said I think it self calibrated on the first start up.

[–] [email protected] 2 points 5 months ago (1 children)

Does that have a built in filament dryer? I know 90% of my issues are solved by drying my filament

[–] Aermis 2 points 5 months ago

I was using structural filament, used for breaking prints apart. Once I switched to the regular PLA everything went fine.

I'm not sure about a filament dryer. I'm sure the P1S comes with something robust.
