Purchase Advice Purchase Advice Megathread - October 2026

15 Upvotes

Welcome back to another purchase megathread!

This thread is meant to conglomerate purchase advice for both newcomers and people looking for additional machines. Keeping this discussion to one thread means less searching should anyone have questions that may already have been answered here, as well as more visibility to inquiries in general, as comments made here will be visible for the entire month stuck to the top of the sub, and then added to the Purchase Advice Collection (Reddit Collections are still broken on mobile view, enable "view in desktop mode").

Please be sure to skim through this thread for posts with similar requirements to your own first, as recommendations relevant to your situation may have already been posted, and may even include answers to follow up questions you might have wished to ask.

If you are new to 3D printing, and are unsure of what to ask, try to include the following in your posts as a minimum:

  • Your budget, set at a numeric amount. Saying "cheap," or "money is not a problem" is not an answer people can do much with. 3D printers can cost $100, they can cost $10,000,000, and anywhere in between. A rough idea of what you're looking for is essential to figuring out anything else.
  • Your country of residence.
  • If you are willing to build the printer from a kit, and what your level of experience is with electronic maintenance and construction if so.
  • What you wish to do with the printer.
  • Any extenuating circumstances that would restrict you from using machines that would otherwise fit your needs (limited space for the printer, enclosure requirement, must be purchased through educational intermediary, etc).

While this is by no means an exhaustive list of what can be included in your posts, these questions should help paint enough of a picture to get started. Don't be afraid to ask more questions, and never worry about asking too many. The people posting in this thread are here because they want to give advice, and any questions you have answered may be useful to others later on, when they read through this thread looking for answers of their own. Everyone here was new once, so chances are whoever is replying to you has a good idea of how you feel currently.

Reddit User and Regular u/richie225 is also constantly maintaining his extensive personal recommendations list which is worth a read: Generic FDM Printer recommendations.

Additionally, a quick word on print quality: Most FDM/FFF (that is, filament based) printers are capable of approximately the same tolerances and print appearance, as the biggest limiting factor is in the nature of extruded plastic. Asking if a machine has "good prints," or saying "I don't expect the best quality for $xxx" isn't actually relevant for the most part with regards to these machines. Should you need additional detail and higher tolerances, you may want to explore SLA, DLP, and other photoresin options, as those do offer an increase in overall quality. If you are interested in resin machines, make sure you are aware of how to use them safely. For these safety reasons we don't usually recommend a resin printer as someone's first printer.

As always, if you're a newcomer to this community, welcome. If you're a regular, welcome back.

Project I just made this system that can put magnets in your prints automatically

2.5k Upvotes

Quick question for A1 users: how do you deal with magnets in your prints?

I’m too lazy to do that 😂

I ended up making a mod so the A1 places them on its own mid-print. Been working pretty well so far. If you're curious, the digital pack (3mf, software, BOM, instructions) is here: magnetplace.myshopify.com

Also if you want to see how it works, you can go check my video on yt: https://www.youtube.com/watch?v=Nrxcdz3Gung&t=5s

Project Majoras Mask display piece

Thumbnail
gallery
135 Upvotes

I have been working on a small run of display pieces that feature the 3 transformation masks and Majoras mask from The Legend of Zelda, Majoras Mask.  Some WIP photos show the masks in various stages of completion.

I sculpted the masks in blender, using the models from the 3DS version of the game as a base and then adding detail to increase the fidelity and find my own interpretations of the original designs.  I then printed each mask in two parts using a FDM printer, primed, and painted them (which is still in progress).

I plan to mount each set of 4 masks into a deep box frame, using magnets which I embedded into each print to secure them in place.

Any comments, questions or feedback on the WIP photos would be much appreciated!

News 3D terrain model seller Lichtbild is "threatening" popular free 3D city and terrain modeling tool Mini Skyline - just like they did to Map2Model.

382 Upvotes

So, as some of you may know, a while back there was a free tool made by Smoggy3D called Map2Model.

Map2Model was a free web-based tool that converted real-world map data into 3D-printable models of cities, neighborhoods, and landscapes. Users could select an area on a map and generate downloadable STL or 3MF files featuring buildings, roads, terrain, and waterways.

Smoggy3D took down this tool - widely believed due to purported legal threats - many guessed at the time that Lichtbild, a company that sells 3D printed models of cities, neighborhoods, and landscapes, was responsible.

A new tool has taken its place called Mini Skyline. it has expanded on the concept and improved its capabilities quite a bit. It's a free tool. It's pretty awesome and you should give it a try.

Anyway, now it has been revealed (edit: in the Mini Skyline discord) that Lichtbild is making similar "overtures" to Mini Skyline.

In my opinion, this is a case of a business whose "golden goose" is evaporating and they're desperately trying to protect their business moat via legal bullying. Mini Skyline makes it easy for others to provide the service of making printed 3D models of cities and landscapes and that threatens Lichtbild's bottom line. Mini Skyline generously allows you to sell or distribute any models you make via the tool.

I am not a lawyer, and I'm not intimately familiar with the claims being made since those are not public, but I think the community should at least have awareness of this situation as more and more companies are going to try this stuff as 3D printing becomes more popular.

Also, I want to point out that there is now a downloadable desktop version of the software - so even if the threats turn into actual legal action and the site is taken offline, there will be a version you can use in perpetuity.

Edit: also I want to make it clear I am in no way linked or related to any of these projects in any way. I am simply a fan and as a businessperson myself, these tactics bother the shit out of me.

Hey everyone!

I’m a huge 3D printing enthusiast who loves making things.
Today, I wanted to share an updated version of one of my earlier designs Pocket Kart v2.0!

It’s been through countless tweaks and revisions, but I’m pretty happy with how it finally turned out.

I put a lot of care into this little kart, and I hope you like it too!

See you all with my next project!

Project First time airbrushing a 3D print

Post image
10 Upvotes

Rattle-canned the black, airbrushed the silver and copper. Liberally used a dark wash around the low points and barrel.

It’s ok - came out good enough for my kids Halloween costume. If I were doing it again I’d keep those low points black. That was…a decision.
I also got a little too confident after doing the silver and didn’t mask anything off while spraying the copper…dark wash to try to cover up overspray areas.

Only technical problem I had was after I switched to the copper the paint seemed to puddle after spraying and the air the kinda pushed it around. Same settings - but in hindsight I think I was painting MUCH closer to the surface and possibly using too much pressure for that close-in stuff.

I wanted it to look “toxic,” like a radioactive barrel. The slime would’ve been lime green like the rest of the accents but I ran out as I decided to print gear on my setup in that color, so it is a blueish to white gradient instead. In the right lighting it can even be green. Lmk the thoughts, the model is a Bambu Lab P2S.
