How to choose a 3D printer: quick quiz and comparison
Printer models change every few months; the right type for you stays right. That is why this guide does not crown a "best 3D printer". It helps you find the type that fits what you want to print, where the machine will live and how much you want to tinker with it. The quiz below asks the six questions that decide it. If you would rather read, the text after it follows the same logic.

The three types of 3D printer
Open-frame filament printer (bed slinger)
A hot nozzle melts a plastic strand and draws the part layer by layer, while the bed slides back and forth under it. That moving bed is why people call these "bed slingers". It is the cheapest and simplest way in, and the easiest to understand and repair. It does very well with PLA, PETG and TPU, and most current models level the bed on their own.
Example families (checked November 2026): Bambu Lab A1 and A1 mini, Creality Ender-3 V3, Elegoo Neptune, Anycubic Kobra.
Enclosed filament printer (CoreXY)
The bed only moves down; the print head moves in both directions on a belt system called CoreXY, inside a box with a door. That makes printing faster and steadier on tall parts, and the closed chamber holds heat, which is what lets ABS and ASA print without lifting and warping. The door also contains part of the noise and smell.
Example families: Bambu Lab P1S and P2S, Creality K1C and K2, Elegoo Centauri Carbon, QIDI Q2 and Plus4.
Resin printer (MSLA)
An LCD screen shines ultraviolet light into a vat of liquid resin and hardens a whole layer at once. The part comes out upside down, hanging from the build plate. The detail is something filament cannot match: common profiles use 0.05 mm layers, and the surface comes out smooth. The machine is almost silent. The trade-off is that every part has to be washed in isopropyl alcohol and cured under UV light, and liquid resin calls for gloves.
Example families: Elegoo Mars and Saturn, Anycubic Photon Mono, Creality Halot.

The six questions that decide it
They are the same questions as the quiz, and the order matters: the first and third ones decide whether resin is in the running.
1. What do you want to print most?
Brackets, organizers, replacement parts and bigger objects call for filament. Tabletop miniatures, busts and parts with tiny lettering are resin territory. If the answer is "a bit of everything", filament covers more ground; for finer detail, a 0.2 mm nozzle gets closer to resin, at the cost of printing much more slowly. The full comparison is in resin vs filament 3D printers.
2. How much do you want to spend?
On a tight budget, start with an open-frame printer and put the rest into good PLA spools. A bigger budget buys comfort: an enclosed printer is faster, takes more materials and needs less tuning. With resin, the printer itself can be cheap, but alcohol, gloves, a wash station and spare film are part of the cost from day one.
3. Where will it live?
Near people (bedroom, living room, home office), the easiest choice is filament with PLA. Resin only makes sense there if you can vent to the outside, because the smell comes out whenever the vat is open. A fast filament printer runs its fans for hours; an enclosed one muffles part of that. In a ventilated workshop or garage, any type works. Just watch the cold: Anycubic, for example, advises printing resin above 20 °C (68 °F), and a cold garage cuts the success rate.
4. Do you want several colors in one print?
That does not decide the type, it decides the bundle: look for the model sold as a combo with an automatic filament changer (Bambu Lab AMS, Creality CFS, Anycubic ACE). They exist for open-frame and enclosed printers. Every color swap throws filament away as purge, and on prints with many swaps that waste shows up in the price; see the guide to multicolor waste cost. Resin prints one color at a time, and color comes from paint.
5. Will you print engineering materials?
ABS and ASA warp in drafts and cold air; for medium and large parts they need an enclosed chamber. Carbon-fiber and glass-fiber filaments wear out brass nozzles and need a hardened steel nozzle: some models ship with one, others sell it separately. Nylon also needs very dry filament. If you will stick to PLA and PETG, an open-frame printer handles them; the difference between those two is in PLA vs PETG.
6. How much do you enjoy tinkering?
If you want it to just work, favor printers with automatic bed leveling, vibration compensation and ready-made slicer profiles, and an enclosed one if the budget allows. If you like tuning and learning, an open-frame printer with a big community and easy-to-find spare parts makes a great lab.
The honest downsides of each type
Open-frame. It needs clear space in front and behind, because the bed travels. On tall, thin parts the moving bed limits speed. Without a box, an open window or an AC vent blowing on it can be enough to lift ABS. Noise and smell stay in the room.
Enclosed. It costs more. With PLA on hot days, manufacturers such as Bambu Lab advise opening the door or removing the lid so chamber heat does not soften the filament before it reaches the nozzle. Some brands rely on their own app, firmware and parts, so a home repair often means swapping a whole module.
Resin. Liquid resin irritates skin and can cause an allergy with repeated contact; nitrile gloves and safety glasses become routine. The alcohol you wash with ends up full of resin and cannot go down the drain: it has to be cured in the sun and disposed of under your local rules. Standard resin parts are brittle, the build plate of a compact printer is about the size of a phone screen, and the FEP film in the vat is a consumable you replace now and then.
What to buy besides the printer
The printer is only the first purchase. For filament:
- Two or three spools to start: a neutral PLA for test prints and, if your parts will see heat or sun, a PETG.
- Spare nozzles: the 0.4 mm one clogs or wears; a 0.2 mm one if you want detail; a hardened one for fiber-filled filament.
- A second PEI plate: textured PEI is the most versatile, and PEI loses grip with use.
- A filament dryer or a sealed box with desiccant: PETG, TPU and nylon absorb moisture and print poorly when wet. Here is how to dry wet filament.
- Tools: flush cutters, a scraper, calipers, a glue stick and isopropyl alcohol to clean the plate.
For resin:
- Plenty of isopropyl alcohol, nitrile gloves, safety glasses and paper towels.
- A wash and cure station, or two lidded containers and a 405 nm UV lamp.
- Spare FEP film, a plastic scraper and a funnel with a filter to pour resin back into the bottle.
- Ventilation: an open window, an exhaust fan or an enclosure that vents outside.

Frequently asked questions
Can a resin printer be my first 3D printer?
Yes, if your focus is miniatures or small detailed parts and you have a ventilated spot. The learning curve is different: less machine tuning and more attention to safety, washing, curing and disposal. People who want to print everything often end up with both, starting with the one that covers most of what they plan to make.
What build size do I need?
Measure the three largest things you want to print. If they fit in 18 × 18 cm (about 7 in), a compact printer like the A1 mini will do; mid-size machines such as the A1 and P1S are 25.6 cm (about 10 in) on each side. Parts bigger than the bed can be split in the slicer and glued together with alignment keys.
Does a 3D printer use a lot of electricity?
Less than most people expect. The MakerPrice 3D calculator starts from an average of 120 W for filament and 50 W for resin. A 5-hour filament print uses 0.6 kWh, about $0.10 at $0.17 per kWh. The same 5 hours on resin use 0.25 kWh, about $0.04. Swap in your printer's real wattage and your rate.
Do I need a computer to print?
To slice, almost always: Bambu Studio, OrcaSlicer, PrusaSlicer and Cura for filament; Chitubox and Lychee for resin. Many printers take the file over Wi-Fi or through a phone app, and nearly all accept a USB stick or memory card, so the computer does not have to stay on during the print.
Is a used printer worth it?
It can be, if you can see it running. On a filament printer, check the plate (scratches and grip), the nozzle, the belts and whether the firmware still gets updates. On a resin printer, the LCD screen and the FEP film wear with use: ask how many hours it has and run a test print before you pay.
