3D printer printing a model using FDM technology

Short answer

Which 3D printer you should choose depends on two things: which technology you need, and what you actually want to print. Choose FDM for functional parts, prototypes and larger objects. Choose resin for miniatures, figures and jewellery, where surface finish matters more than strength.

Which technology and which printer?

Which 3D printer you should choose depends on two things: which technology you need, and what you actually want to print. This 3D printer guide covers both, and ends with the models we see our customers using most in 2026.

Best 3D printers of 2026 – the winner in each category

No printer is best for everyone. Below is the winner in each category, based on what the 2026 reviews highlight, and who it actually suits.

Best overall – Bambu Lab P2S Combo 256×256×256 mm, enclosed, ABS/ASA: Yes, ~8,323 SEK
Best for beginners – Bambu Lab A1 Mini 180×180×180 mm, not enclosed, ABS/ASA: No, ~2,250 SEK
Best on a budget – Creality Hi Combo 260×260×300 mm, not enclosed, ABS/ASA: No, ~3,800 SEK
Best for technical parts – Bambu Lab H2D 350×320×325 mm, enclosed (65 °C), ABS/ASA + PC/PA: Yes, ~17,100 SEK
Best for long-term ownership – Prusa CORE One+ 250×220×270 mm, enclosed (55 °C), ABS/ASA: Yes, ~14,900 SEK
Best for multicolour printing – Snapmaker U1 270×270×270 mm, partly enclosed, ABS/ASA: Yes, ~9,623 SEK

The winners in detail

Bambu Lab P2S Combo – best overall. Enclosed, four colours and quiet enough for an office. Handles ABS and ASA straight out of the box, which its open competitors do not. Reviews describe it as a machine you stop thinking about: it just prints. For anyone who wants to buy a printer and be set for years. The DynaSense servo extruder is a clear step up from the P1S generation, and the AMS 2 Pro has active ventilation that keeps spools dry between prints, which means fewer moisture-related failures. Supports LAN-only mode, so nothing has to go through the cloud. On the other hand, several reviews flag heat build-up and ventilation as weaknesses; it is not enough for PPS-CF, PPA or PC blends that need a 60 °C+ chamber; and it is a closed ecosystem.

Bambu Lab A1 Mini – best for beginners. The cheapest way to get started: it calibrates itself and turns out usable prints on the very first evening. The 180 mm build volume is the real limitation, so measure the largest model you have in mind before you order. For anyone who wants to try 3D printing without investing heavily and who sticks to PLA and PETG. Plug-and-play: reviewers report sharp detail and few failures from the start, and active noise cancelling makes it noticeably quieter than its rivals. The downsides: 180 mm of build height quickly becomes limiting (a standard water bottle will not fit); there is no enclosure, so ABS, ASA and fibre-reinforced materials are ruled out; and it comes with an adhesive sheet, whereas the PEI plates on larger models grip and release better.

Creality Hi Combo – best on a budget. Multicolour printing at roughly half the price of the competition, with 0.03 mm dimensional deviation in testing. The price shows in the details: an open frame, more hands-on calibration and wear parts that need replacing. For anyone who wants multiple colours on the cheap and does not mind tinkering. Multicolour printing at a price point where competitors do not offer it, and a dimensional deviation of 0.03 mm in testing at 500 mm/s. But it is an open bed slinger that is worse for tall prints and rules out ABS/ASA; the PTFE tube needs replacing every 250 hours in multicolour use; and its long-term durability is unproven.

Bambu Lab H2D – best for technical parts. A 65 °C actively heated chamber and a 350 °C nozzle open the door to nylon, PC and fibre-reinforced materials that the others cannot handle. The largest build volume in the comparison, but also clearly the most expensive. For anyone who already knows why they need a large format and technical materials. The best value in the Bambu range for technical materials, and the firmware is described as stable in 2026 (early calibration issues have been fixed). It does, however, waste filament when running more than two materials at once; the optional 40 W laser is loud while the 10 W module is slow on thicker materials; and it is the wrong buy if you mostly print small everyday parts.

Prusa CORE One+ – best for long-term ownership. Open firmware, spare parts for years and support that reviewers repeatedly highlight. You pay more per unit of build volume than with the competition; what you are buying is the ability to repair and rebuild the machine yourself. For anyone who wants to truly own their machine, not just use it. Build quality, reliability and support reputation are in a class of their own, and it is repairable and maintainable, with spare parts available for years. Downsides: the most expensive per unit of build volume (250×220 mm for the same price at which competitors offer considerably more); the camera is poor, colour changes are cumbersome and no nozzle wiper is included; and if you only print PLA and PETG you get nothing extra, since the chamber heat mainly benefits ABS, ASA and nylon.

Snapmaker U1 – best for multicolour printing. The only printer in the comparison that changes colour by swapping toolheads instead of winding the filament back. A colour change takes 10–12 seconds instead of around 90, and the waste is a prime tower of a few grams rather than a pile of discarded plastic. The chamber is semi-open, and the lid costs extra. For anyone who prints a lot in multiple colours or materials and is tired of the waste. Four toolheads give colour changes in 10–12 seconds instead of around 90, a prime tower of a few grams instead of a pile of discarded plastic, and it is an Editor's Choice at Tom's Hardware, three hours faster than a P1P on the same three-colour print. It launched via Kickstarter, so early units may have teething problems; the chamber lid costs extra; and wide feed tubes can cause jams from broken filament that are hard to spot.

Build volume in perspective

The difference between 180 mm and 350 mm sounds small, but it is not. Volume grows with the cube: A1 Mini 5.8 litres, Prusa Core One 14.9 litres, P2S Combo 16.8 litres, Creality Hi 20.3 litres, H2D 36.4 litres. So the H2D holds just over six times as much as the A1 Mini, but it also costs ten times as much.

A1 Mini 5.8 litres
Prusa Core One 14.9 litres
P2S Combo 16.8 litres
Creality Hi 20.3 litres
H2D 36.4 litres

FDM or resin? How to choose the technology

The first question is not which printer to buy, but which technology you need. FDM and resin solve different problems, and that choice determines everything else.

FDM – melted filament. A strand of plastic is melted and laid down layer by layer. Large build volumes are common and cheap, 250×250×250 mm and up. Materials: PLA, PETG, ABS, ASA, TPU, nylon, from decorative pieces to technical parts. Produces functional parts that can take a load. Post-processing: remove the supports, done. Cost: filament from around 100 SEK per kilo.

Resin – SLA, DLP and LCD. Liquid resin is cured by UV light, layer by layer. The level of detail is considerably higher, hence its popularity for miniatures and jewellery. Smaller build volumes; large resin printers are expensive. Often more brittle, and less suited to parts that must take a load. Post-processing: washing in isopropyl alcohol and UV curing are always required. Working environment: resin is an irritant, so gloves and good ventilation are a must.

All three resin technologies cure resin with UV, but the light source differs. SLA uses a laser that traces each layer, precise but slower on large areas. DLP projects the whole layer at once with a projector, which makes the speed independent of how much is in the layer. LCD (also called mSLA) uses an LCD panel as a mask in front of a UV source, the same basic advantage as DLP at a lower price, which is why most consumer resin printers today are LCD-based. Resolution is given as screen resolution: 4K, 8K or higher affects how fine a detail can be reproduced.

Choose FDM if you want to print functional parts, prototypes, brackets or larger objects, and if you want to be able to switch material to suit the job. It is also the easier choice to start with. Choose resin if you mainly make miniatures, figures, jewellery or other small objects where surface finish matters more than strength, and you accept the post-processing. The printers above are FDM models. We sell filament for FDM and so have no first-hand experience of individual resin printers, but the comparison holds whichever brand you end up with.

What should you look for when choosing a 3D printer?

Once the technology is chosen, the rest comes down to what you actually want to print.

Build volume. A bigger build volume always sounds better, but it costs space, money and heat-up time. Measure the largest thing you will realistically print and add a margin. Most hobbyists get by fine with 220×220×250 mm; if you rarely need more, it is cheaper to split the model into parts and glue them together.

Speed. Advertised top speeds of 500 or 1,000 mm/s are rarely reached in practice. What determines real throughput is acceleration, frame stiffness and how quickly the material has time to cool. A stable printer at 300 mm/s often finishes before a shaky one that claims 600.

Heated chamber. If you only need PLA and PETG, an open printer is enough. If you plan to run ABS or ASA, you want an enclosed chamber, otherwise the parts warp. Our guides to printing ABS and ASA explain why.

Multiple colours. Multicolour systems are impressive but waste filament at every colour change, because the nozzle has to be purged. If you rarely print in several colours, it is a cost without a matching benefit.

Nozzle and abrasive materials. Filaments filled with carbon fibre or glass fibre quickly wear out a standard brass nozzle. If you plan to run them, you need hardened steel, so check that the printer supports it, or that the nozzle can be swapped.

Frequently asked questions about 3D printers

Which 3D printer should I choose as a beginner?

The Bambu Lab A1 Mini is the most common first choice in 2026: it calibrates itself, is quiet and gives good results straight out of the box. The limitations are the 180 mm build volume and the fact that it cannot handle ABS or ASA. If that is enough for your models, it is the cheapest way in.

Do I need an enclosed printer?

Only if you plan to print ABS or ASA. These materials shrink as they cool and warp without a warm, draught-free environment. For PLA, PETG and TPU an open printer is perfectly adequate, and it costs less.

How much build volume do I need?

Most hobbyists get by with 220 × 220 × 250 mm. Measure the largest thing you will realistically print and add a margin. If you rarely need more, it is cheaper to split the model into parts and glue them together than to buy a bigger machine.

Is 500 mm/s twice as fast as 250 mm/s?

No. The advertised top speed is rarely reached in practice; what determines real throughput is acceleration, frame stiffness and how quickly the material has time to cool. A stable printer at 300 mm/s often finishes before a shaky one that claims 600.

Is multicolour printing worth it?

It depends on how often you use it. The systems purge the nozzle at every colour change, which costs filament, sometimes more than the model itself weighs. If you rarely print in several colours, it is a cost without a matching benefit.

Which filament should I start with?

PLA. It warps minimally, prints at a low temperature and is the most forgiving. Our guide to the best filament for beginners walks you through the choice, and you will find the full range in the filament shop.

Next step: choose the right filament

The printer is only half the equation. The material you use decides whether the part holds up, how it looks and how easy it is to get right.

If you are a beginner, start with PLA: it is forgiving and comes in the most colours. If the part is meant to be used, not just looked at, PETG is the next step. Our guide to the best filament for beginners walks you through the choice, and in the filament shop you will find everything from PLA to technical materials such as nylon and ASA.
