[Hardware] How to Choose a 3D Printer in 2026: A Beginner’s Buying Framework

Quick answer: Decide what you will print first, then choose the printer. For most beginners printing PLA and PETG (the two easiest and most common filaments), an open-frame or enclosed filament printer both work, and the best pick is the one with the software, support and parts you are comfortable with. Choose an enclosed printer only if you want to print ABS, ASA or other high-temperature materials, and plan ventilation or filtration if you do. Treat build volume, multi-color systems and Wi-Fi features as extras you pay for only if you will use them.

This is a buying framework built from the makers’ own documentation, not a hands-on test. We did not print on any machine named here and make no claims about print quality or reliability. We checked every fact below on November 6, 2026. We do not quote printer prices, because they change often and differ by country.

Start with what you want to print

Before you compare any machine, write down your first three projects. Then match them to a material:

If you want to print	Typical material	What the makers say
Toys, models, desk gadgets	PLA	Prusa calls PLA “the most forgiving material to start with”
Functional parts that flex a little	PETG	Prusa lists it as easy to print and “Open-Air Friendly”
Strong, heat-resistant or outdoor parts	ABS or ASA	Both release potentially harmful fumes and warp more

One more choice comes before everything else: filament or resin. Prusa’s buying FAQ says filament (FFF) printers have a wider range of materials and a larger build area, while resin (MSLA) printers give finer detail on a smaller build area. It also says filament printing can be easier for a beginner. This guide covers filament printers only.

Enclosed vs open frame

An open-frame printer has no walls around the build area. An enclosed printer has a chamber, and some models heat it. The difference matters mainly for high-temperature materials.

Warping. Prusa’s guidance explains that plastics shrink as they cool, and materials printed at higher temperatures such as ASA and ABS can cool too fast and pull the print upward. Its ABS page lists “Requires printer enclosure” as a drawback.
Odor and noise. Prusa’s enclosure guide says ABS, and to a lesser extent ASA, can smell during printing, and that an enclosure can reduce both odor and noise.
Safety around moving parts. The same guide notes an enclosure can keep pets and children away from hot parts.

Materials you can print in each

Bambu Lab’s own filament guide splits materials this way:

Material	Open-frame printer	Enclosed printer
PLA, PLA support materials	Compatible	Compatible
PETG	Compatible, though Bambu recommends an enclosed printer for PETG and PETG-CF/GF	Compatible
ABS, ASA, PC, PA and reinforced versions	Not the recommended choice	Recommended

For the open-frame A1, Bambu’s FAQ is blunt. Because of its open-frame design and lower chamber temperature, it says using ABS, ASA and similar materials is not recommended for large or strong parts, although small, low-infill models are possible. It also says ABS and ASA release harmful and irritating gases, and advises against printing them on the A1 unless the room is well ventilated and people stay at a safe distance. It adds that it does not recommend enclosing the A1.

Heated chambers

Some enclosed printers actively heat the chamber. Bambu’s X2D specification page lists active chamber heating up to 65 °C, and Prusa says the CORE One+ chamber heats up to 55 °C. Bambu’s P2S specification page, by contrast, lists a heated bed up to 110 °C and an activated-carbon filter but no active chamber heating line. Check the specification page for the exact model you want, because “enclosed” and “heated chamber” are not the same thing.

Build volume: how much you need

Build volume is the largest object you can print in one piece. Here are examples straight from the makers’ spec pages:

Printer	Build volume (W × D × H)	Source
Bambu Lab A1	256 × 256 × 256 mm	Bambu wiki
Bambu Lab P2S	256 × 256 × 256 mm	Bambu spec page
Bambu Lab X2D (main nozzle)	256 × 256 × 260 mm	Bambu spec page
Prusa CORE One+ (Gen 2)	250 × 220 × 270 mm	Prusa product page
Bambu Lab A2L	330 × 320 × 325 mm	Bambu spec page

A bigger volume costs desk space and, on most models, money. Bambu lists the A2L at 544 × 529 × 505 mm and 12.8 kg, against 392 × 406 × 478 mm for the P2S and X2D. Ask yourself whether your first projects ever exceed 25 cm in any direction. If not, a standard-size machine is plenty. For a closer look at the larger machine, see our Bambu Lab A2L article.

Multi-color and filament systems

Multi-color printing needs a way to switch filaments. Each maker has its own approach.

AMS-style systems

Bambu Lab’s filament feeders are called AMS. Bambu’s A1 FAQ says the A1 supports only one AMS lite unit, which means a maximum of four colors, and that connecting an AMS to the A1 needs an AMS Hub accessory. The X2D is a dual-nozzle design. Bambu’s X2D page says that in its testing, print quality from the auxiliary nozzle is “slightly lower” than from the main nozzle, so read that note before you buy for color work.

Prusa’s route is different: the CORE One+ works with the MMU3, which Prusa describes as combining up to five colors in one print, and Prusa lists the INDX toolchanger as “Coming Soon” on the product page, so confirm availability before counting on it.

The simple advice: if you do not know that you need many colors, start with single-color PLA and add a multi-color system later only if the printer offers an upgrade path. Multi-color prints use extra filament, and Bambu’s own filament guide warns that rough or abrasive filaments can wear AMS feed tubes.

Software and ecosystem

Slicers, cloud features and open firmware

A slicer converts a 3D model into instructions the printer follows. Both major brands give you one:

Bambu Studio runs on macOS, Windows and Linux per Bambu’s spec pages, and is released under the AGPL-3.0 license, based on PrusaSlicer. Bambu’s pages say it also supports third-party slicers that export standard G-code, such as PrusaSlicer and Cura, but “certain advanced features may not be supported”.
PrusaSlicer is open source under the AGPL-3.0 license. Prusa’s page says it includes over 200 ready-made profiles and that PrusaSlicer, Prusa Connect and firmware updates are included at no charge.
Prusa firmware source code is on GitHub, and Prusa says its CAD files are published.

On networking, Bambu’s wiki describes a “LAN Mode” that lets its printers work on a local network with no internet access. When it is on, remote printing from outside the local network and the Bambu Handy app are not available, and print history is not available. Bambu’s wiki also says that when LAN mode is off, a print file may be sent through Bambu’s cloud, and that you can avoid cloud transfer by turning on LAN mode or printing from the SD card. If privacy matters to you, read that page for your model.

Prusa says its printers have no cloud dependency, and its EasyPrint tool runs in a web browser on a phone, tablet or laptop.

Also check the connection options. The Bambu P2S and A2L spec pages list Ethernet as “Not Available”, while Prusa’s page lists Ethernet and Wi-Fi for the CORE One+. If you want a wired connection, that decides some models for you.

Running costs and safety

Filament, nozzles and sheets

Filament is the main running cost. Prusa’s product page estimates PLA at about $25 per kilogram and says most users spend $25 to $50 a month on filament. Those are Prusa’s own estimates, not a typical figure for every maker. Prusa also lists a replacement nozzle at about $20 and a print sheet at about $37, each lasting “hundreds of print hours” by its estimate. Bambu publishes nozzle guidance in its wiki: the A1’s stainless steel nozzle is not recommended for carbon fiber and glass fiber filaments, so swap to a hardened steel nozzle if you plan to print those.

Ventilation and filtration

Ventilation is not optional with ABS and ASA. Prusa says both release potentially dangerous styrene fumes and recommends a well-ventilated room without drafts directly on the print. For a large number of printers or lots of ABS and ASA, Prusa suggests a separate ventilated room or enclosure. Bambu’s usage guide says ABS and ASA release harmful gases such as styrene that can cause dizziness or nausea, and advises printing on an enclosed printer, avoiding bedrooms and living rooms, and increasing ventilation if children, pregnant women or people with respiratory conditions are present.

Filters help but are not a free pass. Bambu says its X, P and H series printers have activated carbon filtration that must be replaced regularly, so check the interval for your model, and its guide gives a replacement interval in printing hours. Prusa lists HEPA filtration for the CORE One+ as an optional add-on, not included.

If you are unsure, start with PLA or PETG, which Prusa says produce minimal odor and noise, and keep the printer where you can ventilate the room.

Checklist

List your first three projects and the material each needs.
Choose open frame or enclosed. Enclosed if you want ABS, ASA or similar, and then plan ventilation.
Check the build volume against your largest first project.
Skip multi-color unless you know you need it, and check the upgrade path.
Check the software. Can you slice on your operating system, and does the printer accept third-party slicers?
Check networking. Ethernet or Wi-Fi only, and what the cloud and LAN options are.
Estimate running costs. Filament, nozzles, sheets and filters.
Plan a spot with space around the machine and ventilation.
Read the warranty and return terms on the day you buy.

FAQ

Is an enclosed printer necessary?

Not for PLA. Bambu’s filament guide lists PLA and PETG as compatible with both open-frame and enclosed printers, though it recommends an enclosed printer for PETG to protect layer strength, and Prusa lists PLA and PETG as easy to print. An enclosure is recommended for ABS, ASA and similar materials.

What is the best printer for a beginner?

We did not test any printer, so we cannot name one best machine. Pick the one that matches your first projects in the table above, has a build volume you will not outgrow, and has a slicer you are comfortable with. Our Bambu X2D vs Prusa CORE One+ comparison shows the same method on two enclosed models.

How much does 3D printing cost to run?

Prusa estimates PLA at about $25 per kilogram, and says most users spend $25 to $50 a month on filament, with a nozzle at about $20 and a print sheet at about $37. Check any maker’s figures against the price of the filament you plan to buy.

Do I need a PC to print?

You need a way to slice models and send files. Prusa says its EasyPrint app runs in a browser on a phone, tablet or laptop. Bambu lists touchscreen, mobile app and PC app as control interfaces. The A1 needs a microSD card to start a print, per Bambu’s FAQ, while the P2S spec lists 8 GB of built-in storage and a USB port.
