I haven't used a 3d printer yet, but was wondering if things have progressed to point where you can use a consumer grade 3d printer like any other tool, without it becoming another all consuming hobby where you need to spend hours making test prints and fine tuning the design because of your particular printer's limitations and quirks?
The projects I have in mind are simple enclosures with mounting points for PCBs and front panel controls.
Like any other tool, one has to familiarize with it and learn how to use it. For 3D printing there are several aspects:
Software:
Printer:
Some printers may do some of those tasks automatically. Others need to be "upgraded". Not all printers can take all types of materials.
I am not sure whether one would call it a hobby in itself, but due to its nature, there is certainly more involved than when printing a word document on your laser or inkjet printer. There is a learning curve and some trial and error will be involved, especially at first. I have not necessarily spent hours making test prints, but it doesn't always go to plan the first or even second time, so its true that sometimes the job does need to be tweaked and repeated. Simple enclosures with mounting points shouldn't be too difficult, however do expect the occasional print to get messed up and have to be repeated. Some printing materials are trickier to work with than others. PLA is usually the starting point.
There are plenty of 3D models available online so if you already know your printer then one can skip the design step and just download, slice and print.
Its not that difficult to learn, but its not trivial either.
I haven't done any 3D work in a few months, but I am not aware of it reaching the state you desire. It may one day but my opinion is not for a long time if ever. The reason I say that is the degree of engineering accuracy and quality is nowhere near the prices people want to pay.
I do quite a bit of 3D printing, but complete enclosures are the exception rather than the rule for me. Unless a project really justifies the effort, I usually buy an enclosure instead, especially if I need something waterproof or at least resistant to moisture and splashing.
Where 3D printing really makes a difference for me is everything inside the enclosure: custom PCB mounts, connector brackets, cable guides, sensor holders, spacers, as well as servo and motor mounts. Adapters of all kinds are another major advantage. Those are often highly project-specific, and suitable off-the-shelf parts frequently don't exist.
Printing itself has become much easier than it used to be. Modern printers can automatically handle tasks such as bed leveling and calibration, and the overall print quality is significantly better than it was a few years ago.
Now comes the big "but": CAD.
If you want to design your own parts, there is really no way around learning a CAD package. And even after you've learned it, designing custom parts is often surprisingly time-consuming. There is no point pretending otherwise.
Of course, some excellent models are available online. If someone has already designed exactly what you need, it makes perfect sense to use it instead of reinventing the wheel. I do that whenever possible.
Would I recommend getting into 3D printing? That's something everyone has to decide for themselves. It offers fantastic possibilities, but in my opinion the price is a considerable investment of time—especially for learning CAD and creating your own designs.
The enclosure with a lid shown is a good example. I wouldn't want to build it without 3D printing, but the CAD work behind the printed parts took many hours.
For me the hard part was getting to grips with the 3D software.
I have a prusa mini 3D printer which works just great -but don't forget companies such as JLC can print stuff for you at a very reasonable price , should you want to try without buying a printer.
There are also several site that have free 3D print files you can download.
here's one I made earlier...
It sounds like 3D-printing IS indeed an all-consuming hobby. Those who love it can't have enough! It's my fear as well that it would consume too much time so instead of looking to print an enclosure, I try to design my project around off-the-shelf enclosures and have a drill press in case I need some holes.
I get plastic enclosures with knock-out holes so I can knock out a hole or three if I need them for cable glands or buttons.
I design PCBs to fit inside these enclosures and have mounting holes where mounting bosses inside the enclosures are. If you're not designing PCBs yet, you can often get mounting plates for the enclosure, drill holes on the plate where your PCB's mounting holes and put standoffs there.
Yes, 3D printing in 2026 is mature enough for everyday enclosure work, but I wouldn't expect it to be completely “print and forget.” You still need some CAD knowledge and basic understanding of materials, tolerances and printer settings.
Yes, consumer 3D printing has reached that point. Modern printers can produce enclosures reliably. You no longer need endless test prints. Good slicer profiles handle settings automatically. The main challenge is designing tolerances. FDM works well for electronics enclosures. PETG suits functional parts. ASA or ABS handles higher temperatures.
Threaded inserts improve assembly durability. PCB standoffs and panel cutouts are straightforward. You need connector clearance. Large flat parts can sometimes warp.
Surface finish remains below injection molding.
