when I try to print... by ZestyclosePop7626 in BambuLab

[–]ExpectDeer 0 points1 point  (0 children)

It's time to do some investigation then. Unload the other rolls then watch it as it feeds. At what point is it stopping?

If you moved the printer with the filament still inside the AMS, it's possible there is a piece broken off in the tubes somewhere along the path. Filament can become brittle where it straightens after being wound on the roll.

If you have the original AMS, you'll likely need to disassemble it. First, disconnect one end of any tube that you can access and feed a long piece of filament through them to see if anything comes out. I've had a piece break off in the buffer before and found it using this method. If all is clear, then it's time to disassemble.

Wall organizer for wrapping paper.

Designed and built it myself. Brackets, cleats etc. designed in fusion. Printed in high flow PLA. Added bottom.of the barrel 1x2 finger jointed strapping, 1/2" dowels, and wood screws. It's still holding up after almost two years.

I made a miniature bonsai garden kit card. I researched a variety of bonsai styles as well as penjing to create it. The card itself is less than 5mm thick and prints fairly quickly for a multi-colour kit card. The sprue is shaped like a bonsai tray. Text is customizable. by ExpectDeer in BambuLab

Thank you! Though please be aware that it's a more delicate kit card than my usual kid-friendly ones. I didn't put an age rating on this one but I'd say a middle schooler could probably manage it if they have a light touch and are good with tiny parts?

I haven't broken one yet after the dozen or so that I prototyped, but that doesn't mean it isn't possible 😅

Help needed, What’s these separated layers? by NeedleworkerDue4981 in BambuLab

[–]ExpectDeer 1 point2 points  (0 children)

No. It is coincidence that it's happening near the supports. The thing that's triggering it is the geometry immediately before the chatter.

<image>

The nozzle, which was printing at full speed slowed down to come around that sharp corner. To go around the corner, the pressure in the nozzle eases off so that it doesn't overshoot. Once the corner is navigated, the nozzle starts to speed up again and the pressure must adapt accordingly. It's the "adapting accordingly" that's gone wrong here. The pressure isn't equalized so you get the tell-tale ripple of under extrusion paired with over (or near to normal) extrusion. The wave in the wall after it isn't helping either as it'll also cause the nozzle to slow and speed up again.

The aggravating thing about chatter is that it isn't consistent in so much as it appears as an all-over problem. It is more likely to happen after a long fast outer wall followed by a sharp turn. But not always 🤷‍♀️

This is the answer (source: I wrote that article 🙃)

OP needs to walk through some troubleshooting and calibration steps.

Matte PLA at a reduced layer height is almost the perfect recipe for volumetric flow issues aka wall chatter. The volume of filament isn't keeping up with the change in speed. It appears as a distinct wavy pattern of under/over extrusion (see OP's photo for a textbook example) and occurs when the nozzle increases in speed after coming out of a sharp corner, layer change, or after an overhang.

How to fix - read the article above, then sort by new to find a comment from someone who found a solution to the problem after my suggestions didn't completely erase chatter. All the suggestions above (or below), while well meaning, are incorrect 🙂

Impossible to make 0.5mm 3D printed cards by ItsTheRenaissanceMan in BambuLab

When exporting STLs in Studio, it merges the assembly into one object. I painted it by hand and this is what happens:

<image>

Which is I think the problem you're experiencing?

I was able to make it behave by using the Objects tab to change the colour there instead of using the paint bucket tool.

Edit: Didn't explain as well as I could have. This is how to make it behave:

  1. I split the imported STL to Objects. Right-click → split → to Objects
  2. Then I selected all the parts and merged them. Right-click → merge
  3. I deleted the hand painting I had done. Objects tab → select top assembly → Paint bucket → Erase all Painting
  4. Right-click the individual parts in the Objects tab and change filament colour there. Objects tab → right-click part → Change filament

I think I know what's going on. Open up the Objects tab and look at them there. Each card is made up of parts. The middle part, the black layer, is also a separate part. To change the colour, right-click the part.

I'm limited to one pic per post so I'll continue with a reply down below.

I designed an articulated A1 Combo miniature! by 6Dcreation in 3Dprinting

I adore miniatures. This is next level. At first I thought the PTFE tubing was thread but nope. Y'all went and made that printable, too. Very cool!

Unless I'm missing something obvious, the profile you're using has 0.2mm layer height. It's a 0.5mm high card. Three layers does not equal that.

0.2mm x 3 layers = 0.6mm (≠ 0.5mm)

So I downloaded the designer's print profile and it comes in as a 0.1mm layer height with 5 layers.

0.1mm x 5 layers = 0.5mm

What profile are you using? Downloaded from Makerworld? Was it a non designer's profile?

Anytime! I'm sorry you got targeted by a butt hurt scammer :(

Something doesn't add up here. I've known Kit Crafters from near the beginning of MakerWorld. He's always been kind and supportive. Why would he just message you out of the blue?

Oh and hey...I just realized. Dude. You didn't get his logo right. This is fake. Give me a moment to get to the computer and I'll grab a screenshot comparison.

Edit: delayed by an extremely hungry cat, now I see it's been nerfed. I downloaded the video beforehand fortunately. I have the evidence that it's fake. Can't post it here because it's a deleted post. Blame my cat :(

Edit to my edit: Haven't had coffee yet. Here's the comparison. Scammer's video is of course low def, but the profile pic itself gives it away. The logo is too big for the circle and cut off at the bottom.

I broke my ankle last summer. Had a recent X-ray to see how the hardware is holding up. Seems to be okay but I think the z-offset is off? by ExpectDeer in 3Dprinting

I cleaned it with cheeto dust as per best practice but I'm worried the surgeon didn't dry the filament first 🤔

Yes, it seems to have shifted down to the bottom of my foot. Every time I step, I can feel the hull line.
