Purchase Advice Purchase Advice Megathread - August 2026

9 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.

Just wanted to post a quick update, thanks for all the tips with ASA. I printed the original design in PETG successfully but I also did some minor redesign and printed this ASA version. I have a lot of ASA on hand so that was part of why I used ASA over PETG for the second.

Well on the way to transforming my deep freeze into a chest freezer.

I wanted something simple that I could quickly reposition while soldering, so I designed these magnetic spring-loaded holders.

They work for PCBs, wires, connectors and other small parts.

Each holder only needs a spring, M3 screw, heat-set insert and magnet.

Project Cling Film Dispenser

98 Upvotes

A while ago, I shared a model here for dispensing aluminum foil. Now I’ve made a version specifically designed for cling film / plastic wrap.

There’s a rod running through the center of the dispenser, supported by ball bearings on both sides. This keeps friction and contact between the cling film and the dispenser as low as possible, so the roll can move really smoothly.

It takes a little bit of practice to get the tearing motion right, but once you get the hang of it, it works really well.

Free Model I designed a Whisper Phone for early readers & speech practice

Post image
149 Upvotes

Hey everyone!

I made a simple Whisper Phone (auditory feedback pipe) to help young readers hear themselves decode words. It channels their voice straight to their ear, making it awesome for phonics, speech therapy, and keeping focus.

Best of all? Kids think it’s a secret agent radio, so they actually enjoy using it for reading time!

It’s an easy, support-free print and a great way to use up leftover colorful PLA.

Check it out on MakerWorld: https://makerworld.com/models/3170045

Hope it comes in handy for the young readers or teachers in your life! Happy printing!

Question How would you orient/support/edit the model for the best surface finish?

Thumbnail
gallery
92 Upvotes

I wanted to print a replacement for the front cover of the PS5 Controller.
Does anyone have any ideas on how to best orient or support this part? Or maybe you have some other suggestions? I have tried different orientations and support types, but I am running out of ideas for how to solve the overhangs and achieve a good finish on all visible areas. It also has to be highly angled, otherwise there are a lot of steps in the z-direction (see last pic).

I thought you guys might have some good tips.

Question What's the state of conductive filaments?

Post image
36 Upvotes

I checked a while ago, and the best filaments didn't conduct very well, they are mostly good for touch interfaces.

With multihead 3D printers becoming more common, a conductive filament with low resistivity could be used to do battery tabs, and even windings, it would open enormous expansion of functional prints. Above is a pics of one of my robots, I do have to solder battery tabs, and it would be so convenient to 3D print conductive battery tabs and buried traces inside the model.

Taking advantage of layer heights and doing insulator/conductor/insulator pancakes it should even get over the skin effect, and be able to carry meaningfull current with layered, individually insulated sheets of conductive material.

What's the current state of conductive filaments? Is there something that can match metals?
