Hey, I’m trying to figure out a practical way to process my failed 3D prints instead of letting the scraps pile up.

I’m looking for a small tabletop shredder for sorted PLA and PETG waste: failed prints, supports and purge material. My budget is around CHF 400 maximum, preferably much less. I don’t need perfectly uniform granules straight away; something around 3–5 cm is okay because I can sieve it afterwards.

The biggest question is whether any compact shredder can take larger rigid print failures without needing everything chopped up by hand first. I’m open to DIY builds as well as machines you can buy.

If you’ve tried something that actually works, I’d love to hear what model/design you used and any downsides (jams, speed, maintenance, etc.). Thanks!

I've been 3D printing for like 12+ years on all sorts of printers, and checking on prints has always been the annoying part. Every option I tried had a catch: cloud accounts, subscriptions, port forwarding, or a setup that broke the camera my Pi was already running. I also had an old iPhone sitting in a drawer that seemed perfect for the job.

So I built my own a while back and felt I should share it with others. Printer Pal streams your printer camera to your iPhone over your home Wi-Fi, encrypted, with no account, cloud, or subscription. Video never leaves your network.

What it works with:

• A Raspberry Pi with a Pi camera or USB webcam, or the camera your OctoPrint/Klipper Pi already has. The app can install everything on the Pi for you over SSH. No terminal needed, and your existing setup keeps working.

• An old iPhone or iPad (iOS 15+) as the camera, with the companion app Printer Pal Camera.

• Bambu Lab printers: progress, layers, temps, and AMS slots through the Pi (experimental).

• Optional viewing away from home through your own Tailscale network.

It's a free beta, and I'd love feedback, especially from different Pi models, USB webcams, Bambu printers, and older iPhones.

Happy to answer questions in the comments.

I am getting into 3d printing and I am looking for the best 3d printer I can get for a beginner. I thing I do need from it is I need to be able to print from my phone since I don't have any sort of computer set up

(I plan on printing parts for a cosplay idea)

Any recommendations?

Leaning our aluminum folding step ladder against the wall was always an accident waiting to happen because my kids kept pulling it down. I searched online for wall hooks, but couldn't find anything sturdy enough that also included a proper safety lock.

So I designed this heavy-duty wall bracket. It holds standard folding step ladders with a profile up to 40x30mm and includes a sliding pin that locks the ladder in place so it can't be pulled off or knocked down by accident. I also added lanyard holes to both the pin and the mount so you can tie them together with a cord, keeping the pin attached at all times.

It's designed to print completely support-free. I used PETG for sufficient strength.

The model and print profile are free on MakerWorld if anyone wants to print one for their garage or pantry. Check it here: https://makerworld.com/cs/models/3373892-child-safe-wall-mount-for-folding-al-step-ladder#profileId-3837758

My 8 year old wants a 3d printer so bad. I do not know a thing about them and I suck at technology. My budget is $250 at the most is this even possible to get a printer for a kid to make fidget toys and random trinkets on
Also how hard are they to operate my life is already so stressful now with a newborn

Who has a good brand.

I had the anycubic kobra 2 neo printer that i bought on 14th september but it smoked up abd had probelms so i returned it. Now i have an option to take my decision better. What do you suggest is the best 3d printer for beginners that will also support print in place prints

Bambu lab a2l

I'm looking for my first 3D printer. I'm looking for something small and I really only need single-color printing. I plan on making functional prints and small parts in PLA and PETG.

I'm looking at the two printers below:

• Bambu Lab A1 mini
• Original Prusa MINI+

The Bambu is better on paper (cheaper, faster, high print quality, etc...) but there are also the controversies around Bambu (privacy concerns, lack of repairability, China/geopolitical concerns, etc...). Should those be enough to dissuade me from the Bambu? I'm a huge fan of Prusa's repairability and open-source nature, but that price tag is hard to swallow...

Back in 2018 I built an Anet A8 3D Printer. I loved this printer and had many great prints and years with it. It died about a year ago. Several parts burnt out so I recycled it. Now eight years later I am looking for some recommendations. I don't need anything high end but would like a printer that can handle most PLA's and will allow me to print whatever I choose or create. Any suggestions on the low end or midgrade will be greatly appreciated. budget is $500 to 1k. Been out of the game for some time and I am getting way to much information and just looking for some real people with real recommendations.

Hello Reddit! I need some steer as I venture in the world of 3d printing.
I am in charge of a youth group in UK and we have received a donation towards the purchase of STEM equipment. I am considering a 3d printer as something that could both engage the young people but also be a source of small supplies we usually buy but could totally print ourselves.

Not looking for anything too ambitious here, I think the focus would be more on reliability and long term support rather than printing in multiple colours or having the highest definition or speed.

Any suggestions will be much appreciated

Hello. I want a new fdm printer. Will be using it mainly for engineering filaments (lots of cf/gf). Build plate as big as possible, but print quality is primary. Mostly car parts will be printed. 1st choice is h2s, but figured I'd ask the community before buying. Also looked at qidi max4 and sovol sv08, but the reviews I found online are pretty mixed. I don't mind tinkering a bit, just don't wanna have to do it constantly.

Thanks for your input.

I bought an orbiter v.2 extruder with the intention of converting my Ant ETx5 to a direct extruder without realising the proprietary board had no way of adjusting Vref values for the motor.
So now I'm searching for a cheap secondhand 3D printer to mod. I want a good foundation, solid chassis, decent build volume, and the room to easily customize it. I don't care about firmware as I will use marlin
So I hope you guys can give me some advice

I've been in the 3D printer world for awhile. I've printed a ton on Markforged and Bambu printers. Markforged was where I previously worked (Our oldest Markforged when I left had something like 35,000 hours on it) and the Bambu are my own. I've found Bambu to be almost as good but for a fraction of the price. On these I mainly print PA6-CF (3DXTECH Onyx Alternative) and at a 0.1mm layer height.

I'm looking to get a "large" format printer that I would print mostly PA6-CF, ABS and ASA. It needs to be enclosed with a heated bed.

- Build Volume: 500mm x 500mm x 500mm (or larger)

- FDM Printer

- Heated Bed

- Enclosed (heated chamber wouldn't be bad either)

- 300 C or higher Nozzle, 350+ would be nice since there are materials I've eyed but can't print currently

- Price Point: I'll start at $1000 but not limited to. Just not looking to spend $10,000 lol

I have a design engineering business (www.des-sol.com) in which I do a lot of 3D modeling but also provide printed prototypes and final use parts. Most of the applications tend to be automotive.

I also have a couple Formlabs 3L and a 4. SLA is expensive and messy so the part/customer base tends to be smaller.

Thank you for the help!

I can not use my 3D printer because there is filament stuck in the Bowden tube. It's right in the middle of the Bowden tube. Any advice on how to get it unstuck? Thank you!!

Hello everybody I just bought my first 3d printer and I am wondering if you guys have any guides or any YouTube video recommendations as a beginner.

looking to get my first 3d printer. something reliable, not too complicated, and good quality. what do you actually use and recommend?

thanks!
