I’ve casually discussed with several of other printers on here, but would love to casually chat about the hobby

What you print with, materials, settings, slicer, etc.

Me personally, I use a heavily modified Ender 3V2 that runs klipper with a dual z axis and direct drive extruder hotend (orbiter 2.0 on a V6)

I print a variety of PLA, PETG, and just recently got into ABS and ASA

I’m currently working on wiring up a stealth burner setup for the X axis though (in preparation for my Voron build 👀)

And I just recently finished printing the Input Labs Alpakka controller! (which is super duper cool)

But yeah I’m down to answer any questions or talk about anything 3D Printer related

I've had an interest in 3D printing since first hearing about it many years ago, but at the time printers were expensive and learning materials and resources were scarce. Nowadays, it seems like 3D printing is as common as regular old 2D printing but I feel left in the dust.

What's really making me want to get started now is I've collected a lot of junk over the years that I've told myself I could repair, but a lot of the repairs would be much easier with a 3D printer and custom modeled parts. Dearest to me would be an old watch that my grandfather gave to me before he died. The part of the watch that connects the strap to the case (lugs, I think it's called?) has broken off and gotten lost, and it's a proprietary part with no replacement parts available. I'd love to just 3D-print a solution but have no idea how to get started.

I consider myself a creative person, I have plenty of experience with Photoshop and illustrator, but I have never once dabbled in 3D modeling software like Blender or AutoCAD. The closest I ever got was peering over the shoulder of an artist who was working on a video game character model in Zbrush, or maybe working on custom Half-Life maps in Valve Hammer. So I'm looking for the most basic, easy-to-follow set of instructions to get me from zero knowledge to successfully printing bespoke DIY repair parts at my local makerspace.

Would also love to have this be a discussion on 3D printing in general. How did you get started? How have the tools and techniques evolved over the years? What do you think are the next big things coming in the hobby? What are things you wish you knew when you started but only learned after mistakes were made? Share your thoughts and anecdotes, I'd be happy to read them.

I don't intend this to be a sales pitch or anything, I just wanted to share my impression of the Bambu Labs P1P 3D printer in case anyone on here was curious and maybe considering buying one themselves.

I have owned a few Prusa FDM printers over the years but recently tried the Bambu Labs P1P after seeing tons of rave reviews, especially in terms of how fast it prints. Anyone that has done any 3d prints knows that print time is among the least enjoyable aspects of the hobby: lots of waiting.

Right out the gate, the P1P is a solid device with impressive construction given its relatively low price tag (I got it for $600 USD). And this thing easily rivals high performance machines in it's same "category", like the Prusa mk 3 and 4. And those are typically more expensive; the P1P comes 99.5% assembled at that price but a Prusa machine fully assembled is around 60% more expensive.

Most of the "assembly" is just removing packaging, like zip ties, that kept the unit safe and secure during transit. Then you connect the power cable, screen, spool holder, and filament tube. And that's it. The whole thing took maybe 10 minutes.

Getting the WiFi to connect is impossible for me at the moment, but I don't mind copying sliced gcode to the included microsd for printing. Sure, sending the gcode over WiFi would be super cool, but my Prusa doesn't do that so it's not like I've lost something. I'm hoping to eventually figure it out but that's not a deal breaker for me. I'm guessing I just need to temporarily move the printer next to the WiFi router but I haven't made time for it because I'm enjoying just printing off the card.

With the included 0.4mm nozzle (a standard size), it prints typically 2 to 3 times faster. Something that takes 23 hours might take 11. Something that takes 3 hours might take 1. For larger and more complex prints, you can get stuff done so much faster. For smaller and simpler prints, you no longer need to plan batches either first thing in the morning or overnight, you can just start them whenever. Whatever you printed before, you can print 2 to 3 times as many in one go in the same amount of time.

I don't have the AMS system but hope to get that at some point. If it has the same high quality build and performance as the P1P then I'm certain it will bring me simple multi-filament printing. And although I'm not nearly rich enough to afford more than 1 AMS, you can technically connect up to to 4 at once. Each unit holds up to 4 filament spools, so 4x4 means you could theoretically use 16 different filaments in a single print. The colors you could have! But each unit is like $350. Ouch.

I only have 2 real gripes with it so far. First, it purges way too much filament at the start of a print. I get why it does that, it absolutely ensures that your filament is always properly primed to assist in printing that critical first layer correctly, but it feels very wasteful to have a seemingly-excessive amount of filament thrown away with each print.

Second gripe is that the default spool holder is awful to access. You are likely to put the back of the machine facing a wall and that's where the spool holder will end up facing: the wall. You need to ensure the printer is a little more than two spool's width away from the wall - at the very least - so you can slide your spools on and off. Thankfully the bed doesn't move back and forth like with traditional fdm printers, thanks to the corexy technology, so you can more easily plan out where to put it and how much space it will need.

I haven't messed around with them yet but I just got additional hotends for it that I will be testing soon. The pack I got contains 0.2mm for prints that require very fine detail, 0.6mm for prints where detail is slightly less important than speed, and 0.8mm for when you want to go fast and don't care how much detail you get. Because they use a proprietary construction of hotend, you must use theirs, but the upside is that it's fairly fast and simple to switch them out. Most hotends, you just replace the tip, the actual nozzle. But because filament can gunk up the threads, you need to run it hot to unscrew the nozzle, which is very dangerous. With the P1P, you just pull off the magnetic faceplate, undo a few screws, swap the hotend, put the screws back, and pop the faceplate back on. In just a few minutes, you're done. And no need to turn on the hotend either; just unload your filament prior, let it cool down, and swap away. A much safer and more pleasant experience.

Overall, I'm in love with 3d printing all over again. It's the same feeling I got all those years ago when I did my very first 3d print. And sure, the Prusa is still great when you want high quality detailed prints. Going slow and steady wins that particular race still. But I get quality that is 90+% comparable to what the prusa gives me in exchange for literally 2x to 3x print speeds. That's an easy trade for me. And the slicer software estimates that some of my larger and less detailed prints could print in right 2/3 the time using the 0.6mm nozzle instead of the default 0.4mm. That translates to roughly 7 hours on my Prusa (0.4), 3.5 hours in my P1P (0.4), and 2 hours on my P1P (0.6). Given how much easier it is to swap out nozzles on the P1P, I can see myself actually doing that not frequently for certain prints that, like in my example, see substantial benefit.

I'm very excited to see how this machine holds up in the long run!

I have a box of scrap parts of PLA left over from 3D printing and I'm wondering what to do with them. PLA can apparently biodegrade but only in really specific conditions I don't think I can achieve like keeping it at 60c. I know there is a device that can turn the scraps in to new filament but its way too expensive for me. What should with this stuff?

I've got a K40 laser engraver that I've had a lot of fun getting up and running with K40 whisperer on a Raspberry pi, and lately I've been thinking about getting a cheap 3d printer. Does anyone have an entry level 3d printer they like and want to recommend? What kinds of projects do you like to make? Anybody have a desktop cnc or other fun toys? Let's hear about 'em.

I'm personally a little busy for 3d printing at the moment - but I love to see and be inspired by what others are doing. I know this is text based, but I'm also interested in what issues you are running into. I find it useful to see examples of what common problems and solutions others are running into.

I've got an "old" Prusa MK3S that is still going strong for me. When I get the time again I've got a few projects lined up: a brain, a mask, and a fluid desk sculpture that I'm excited to get printing.

What have you been printing lately?

If there aren't many 3D printer hobbyists here, still feel free to comment if your interested. It's a great hobby open to all price ranges and skill levels. If you can't afford a printer, many libraries and schools have printers open to public use.

What are your projects? What do you like to print? Materials? Printer? Etc.

I've been getting into 3D printing more seriously. I have worked with cad software for many years but only printed on occasion, never personal stuff. I bought the Prusa Mk3 kit at the end of last year and patiently waited for its mid-spring arrival. It's a fantastic printer worth every bit of waiting. I print in PLA for fun stuff & online models and PETG for functional & outdoor models.

My most recent print was a window fan mount for my car for car camping. I designed it to create some airflow to keep the car from getting stuffy while keeping bugs and water out. It's very low power, so no issue there.

I am currently printing the pangolin awareness toy from thingiverse in white PLA for fun.

What do you like to do with 3D printing? or what do you think of it?
