What have you 3D printed for your TJ?

You can anneal 3D prints to improve this, but doing so has its own set of caveats.

I’m aware of the practice, but count me a skeptic on that one. In order to reap substantial benefits, I think you’d need to get up to the glass-transition temperature to affect the layer bonds enough to strengthen them, but by definition, that’s where material starts to flow. Doing that while maintaining dimensional stability seems a fools errand to me. The analogy to me is welding aluminum. The base parts are solid until they aren’t…

Maybe I’m wrong, though. It’s entirely possible I just don’t understand the process well enough.

I'm not saying I do it, only that some apparently do. As noted, there are potential issues. I believe the process is intended to keep the temps below, but just. I haven't really found it necessary with anything I've designed thus far and I'm not sure my oven would be up to the task, either.

No worries - I didn't take your post as in support of the practice - just that it is done. Sounds like you share my skepticism, or at least some of it...

I try to base my designs on the limitations of the chosen material as-printed. Annealing metals is one thing, annealing printed plastics feels like a bit more of a dark art, with some luck/chance thrown in for the feck of it (esp. considering the oven in my rental). As well, the whole process seems like at least a minor PITA. If I spend 12 hours printing a part, ruining in attempts to anneal it feels a bit foolish and wasteful. Plus, I'm not much of a cook when it comes to food, not sure what it says about me if I start baking more plastics than meat. 🤨

If strength is a concern due to layering, I'll typically alter the design orientation or use a glue-up assembly to maximize strength in the directions needed. And if that doesn't solve the issue, then it's likely I'm using the wrong material and/or process for the task. Trying to channel my inner Kelly Johnson and "KISS". :geek:

I've dabbled with annealing PLA 3d prints. The biggest benefit is the increased heat deflection temp after the PLA is allowed to recrystalize. The biggest problem is that the material doesn't seem to disform consistently enough to develop a simple manual method that makes usable parts on the first attempt. While it does help the anisotropicity in strength, the variations in built up stresses due to varied extrusion speeds. This makes it very hard to predict exactly how a part will deform during the annealing, so it was a game of trial and error. I think it could be done programmatically in the slicer but the final results were underwelming anyway. Personally I'd say its a waste of time, especially if the printer can support more advanced materials. Slower prints, bigger nozzles and smarter engineering seems to consistently be a better answer.
 
Another option for those with AMS1's

I've actually ran into my first real issue with a Bambu printer! I need some PET-CF parts for a project and the filament is brittle. Brittle enough that when the pront head moves over to the far right side of the printer it snaps the filament in the feed tube. Sounds like this is a pretty known issue on the H2 series printers and the fix is that you have to remove the tube from the cable guide when you want to print these materials. In the mean time, I've ordered an AMS HT, and a couple other small things for my machine for a little upgrade. I have some ASA-CF I'm running for some mounts and brackets around the house and having a way to dry filament at an elevated temp without occupying the print bed would be nice.

But pay heed, if you use PET-CF, you need to reroute the tube!

Seems I have as well...not so much the printer as one of the new HT units. Bound to happen but the second AMS HT unit I received seems to have at least one defect. I've got an open support ticket as of yesterday on the issue, but for the sake of everyone here with BL products, I'll elaborate on the ticket thing a bit...

Seems the preferred channel of dealing with this is not calling customer support (you can't, really). you have to document the issue with photos, video and a description and file a support ticket via the BL website. Ok, not a big deal, I'd already done most of the work assuming they'd ask for this anyway. Where I ran into problems was when submitting the completed ticket form, apparently if you don't attach everything noted in the ticket form, it will not submit.

Now, I'm unlikely to supply printer logs (or project files) to BL anytime, certainly not all of the logs, and definitely not when the issue has nothing to do with the feckin' printer. This is an issue with a new, defective AMS HT and those logs will show nothing useful in solving the problem. And yet, I could not submit the form without attaching the logs.

Hating the thought of it, I gave their live chat a shot, knowing full well it's going to be Ai driven and not human. "Very slow and quite thick" would be my initial assessment, though at least I wasn't talking to "Steve" in a Southeast Asia call center who's doing his best with the English language. I had to repeat both the hardware and ticket form issues numerous times until the thing understood (after vanishing for a good 10 minutes) and offered to fill out and submit the ticket for me. Again, had to repeat everything numerous times and discovered it's best to type your responses as if you're ignorant. If you write sentences like I am here, it seems to get confused. Things like "new AMS HT defective" and pasting the error codes seemed to work best.

In the end it did successfully file a support ticket for me, though all it did for the content was a direct copy and paste of my replies in the chat interface. BL support responded about an hour ago, and while offer of a replacement was proposed, they want me to follow some of their support wiki articles for checking the internal cable connections in the unit first, alleging that they can sometimes come loose during shipping. Not really what I'd hoped for but pretty much what I expected. While I'm okay with this, I dare say some customers might not be comfortable opening up the hardware.

All that said, I do like the HT's. For the money, having at least one feels like a solid addition to almost any BL printer setup, even if you don't have a typical AMS unit.

Forgot to mention, I tried to fake the form out by uploading bogus log files (renamed text files). It ignored them and continued to ask for the correct logs. :cautious:

Completely novice question here.

My wife is into Doll house miniatures.

What is a good entry level inexpensive printer for her to do furniture, stairs, appliances on??

Keep in mind im am technology stupid and southern, so please keep the answers simple with links and pictures 🤣 🤣

On the dual-hotend printers (H2C and H2D), the wiki guide says print soft materials (TPU) in the right hotend only and brittle materials in the left only. Additionally, with the softer TPUs, they recommend removing the top off the unit and feeding from above to reduce friction in the feed route. Learning all that was disappointing because I bought a Bambu for its “plug-n-print” reputation, but it’s not the end of the world.

Reminds me of a survey our water company wanted everyone to fill out regarding the water service line from the meter to the house. They're concerned about old lines leaking, etc, etc - fair enough. The survey asks what the line material is, if its been replaced and when. Sure - new PEX in 2023. THEN, they want you to submit a picture of the thing, and the survey won't submit without one. I ended up creating an image file that said something to the effect that it was replaced in 2023 with PEX, and if they wanted a picture of it, they could feel free to come out here and dig it up to take one because I wasn't going to!

I'd think a Bambu A1 would be the most economical Bambu choice.

Would she want to print in multicolor or does she paint these items after she's complete?

I went through their support system because they put a printable mouse kit in the box for my printer. I didn't order it so when it was missing a piece they kept asking for receipt and a picture of the shipping container etc. It was frustrating but they did finally take care of it.

This is the first one I thought of as well, the A1. Or the A1 Mini.

I imagine if I pressed the issue they'd just send another unit out, but checking the connections seems easy enough. I'm sure they'll take care of it if that doesn't work.
