A 3D printer can be one of the most useful things in a home, or an expensive toy that gathers dust. Whether it is worth it comes down to what you want to make and how much time you want to spend. Here is what it costs and what people use them for.
About this guide: prices are from the official manufacturer stores in October 2026 and change often. Running costs use the manufacturers’ own figures. The uses come partly from my own year of printing on a Prusa Core One+. More about me.
What does a 3D printer cost?
| Level | Example | Price at the time of writing |
|---|---|---|
| Entry | Bambu Lab A1 mini | €189 |
| Full-size open printer | Bambu Lab A1 | From €259 |
| Enclosed mid-range | Bambu Lab P1S / P2S | €379 / €519 |
| Enclosed, open source | Prusa Core One+ kit / assembled | €1,049 / €1,349 |
Not sure which level you need? The printer finder narrows it down in three questions.
What does it cost to run?
Filament is the main running cost. Prusa says most of its users spend about $25–50 a month on it. Electricity costs less than most people think. Bambu Lab lists the P2S at about 200 W while printing PLA, so a 10-hour print uses about 2 kWh, which is around €0.60 if your electricity costs €0.30 per kWh. Now and then you need a new nozzle or build plate. Software from the big brands is free.
What do people actually print?
- Replacement parts that are hard to buy, like clips, knobs, brackets and covers
- Drawer inserts, wall holders, shelves and tool holders
- Custom holders and jigs for the workshop
- Gifts and decorations, such as name tags, planters and lamps
- Figures, board game inserts and miniatures
- Cosplay props, RC parts and model building
For me it has been everything from tools and shelves to things that are just for fun. Free model libraries like Printables and MakerWorld mean you don’t have to design anything yourself to get started.
The downsides
- It takes time. Prints take hours, and you will have some failed prints while you learn.
- It needs space and a stable table, ideally where the noise doesn’t bother anyone.
- Some materials need care. ABS and ASA give off fumes and are best printed in an enclosed, filtered printer. Resin printers need gloves and ventilation.
- Not everything is cheaper to print. Mass-produced items are often cheaper to buy.
Is it worth it for you?
- Yes, if you like fixing and making things, have a hobby that needs custom parts, or enjoy learning a new skill.
- Probably not, if you only need one or two specific objects. Ordering a print from a print service may be cheaper.
Modern printers have made the learning curve much gentler. A self-calibrating printer like the Bambu Lab A1 mini or A1 is a low-risk way to find out if 3D printing is for you.
Frequently asked questions
Is it safe to run a 3D printer in a bedroom or home office?
Health groups advise against it. The American Lung Association recommends keeping printers out of occupied rooms such as bedrooms and offices, and suggests a separate room with the door closed while the printer runs. Filament printers release ultrafine particles and volatile organic compounds (VOCs) as the plastic melts. PLA releases less than ABS, but it still releases both.
If the printer has to share a room with you, NIOSH lists what lowers exposure: an enclosed printer with a filter or an exhaust to the outdoors, and checking the print on a camera so you are not standing next to it. Bambu Lab has had a few printer and filament pairs tested to the UL 2904 emissions standard, for example the A1 and P2S with Bambu PLA Basic. That result covers only the tested combination under lab conditions. Owners who print in a bedroom commonly report sticking to PLA and opening a window.

How loud is a 3D printer? Can I run one in an apartment?
It depends on the model and the print settings. Bambu Lab rates the A1 at under 48 dB in silent mode. Most manufacturers do not publish a figure for normal printing speed. P1S owners on the Bambu Lab forum describe the fans as the main source of noise, because the part-cooling and chamber fans run at full speed in the default PLA profile.
In apartments the more common complaint is vibration through the floor. P2S owners on the Bambu forum report that the sound reaches the unit below even when the printer seems quiet in the room. The fixes they describe most often are a heavy paver on foam or rubber pads under the printer, and slower print profiles at night.

Can I leave a 3D printer running overnight or while I’m out?
Owners commonly report running long prints overnight, and printers have firmware checks for this. Prusa printers, for example, switch off all heating if the printer sits idle and heated for more than 30 minutes, and show a warning if the heatbreak thermistor disconnects. NIOSH says a nozzle that is working and set correctly is usually below the temperature needed to start a fire. Printer fires that owners have reported traced back to hardware faults.
Wiring faults can show up on new printers too. In 2024 Bambu Lab recalled the A1 over a heatbed cable problem and told owners to stop using the printer until it was fixed; Bambu said fewer than 0.1% of A1 printers had reported cable faults. If you print unattended, put a smoke detector in the room and keep the printer away from anything flammable. A camera you can check from your phone lets you stop a failed print early.

How much electricity does a 3D printer use?
Bambu Lab lists the P2S at about 200 W while printing PLA once it has warmed up. Prusa lists the Core One+ at 90 W for PLA and 110 W for ABS. The draw is higher while the bed and nozzle heat up, and Bambu rates the P2S at up to 1,200 W maximum.
As a worked example, 100 hours of PLA printing in a month is about 20 kWh on a P2S and 9 kWh on a Core One+. At 30 cents per kWh that comes to $6 and $2.70. Use the rate on your own power bill to get your number.
How much maintenance does a 3D printer need?
Expect a quick clean before most prints and a longer session every few months. Prusa’s schedule for the Core One+ is to clear debris and clean the nozzle before each print, check the X-axis rail, belt and fans every 200 print hours, lubricate the linear rail every 3–6 months, and check the electrical connectors every 600–800 print hours.
Bambu’s guide for the P1 series asks for a monthly check of the carbon rods and steel rods for dust, grease on the Z-axis lead screws every three months, and an anti-rust treatment on the steel rods every three months. Bambu warns against putting grease on the carbon rods. Schedules differ between models, so use the guide for your exact printer.

How long does a 3D printer last?
Owners commonly report printers still working after many years. The parts that wear are the ones that move or get hot, such as nozzles, belts, print sheets and fans, and both Prusa and Bambu Lab sell these as spare parts.
Before you buy, check that the brand sells spare parts for the model and still releases firmware updates for its older printers.
