3D printers, ranked by what actually sells — on offer now

Why these are ordered by sales rank, not by a per-unit price

Every other section of this site ranks on a ratio, because filament and resin are commodities where cost per kilo or per litre is the honest comparison. Printers are not. There is no meaningful “per millimetre of build volume” number, and pretending otherwise would produce a confident-looking ranking that means nothing.

So this page starts with what actually sells: Amazon’s sales rank, best seller first. That shows which machines people are choosing, not which one suits you. The On offer now filter narrows it to printers with a live price drop, and where we show a percentage it is measured against the typical price over the last 90 days, a time-weighted median rather than an average. For the choice itself, see our printer reviews or the printer finder.

What actually matters when choosing

• FDM or resin. FDM (filament) for functional parts, larger objects and lower running costs. Resin for fine detail and miniatures, at the price of mess, fumes and consumables. Most people who buy resin first for “detail” end up wanting an FDM printer too.
• Automatic bed levelling. The single biggest quality-of-life feature. A printer without it is not unusable, but you will spend evenings on first layers instead of printing.
• Direct drive vs Bowden. Direct drive handles flexible filament far better and is generally more forgiving. Bowden setups can be faster and lighter.
• Build volume. Almost everyone overestimates what they need. A 220 × 220 mm bed covers the overwhelming majority of prints.
• Enclosure. Needed for ABS and ASA, useful for warping-prone materials, irrelevant for PLA and PETG. Can be added later.

The real cost of a cheap printer

A £150 printer and a £400 printer will both make parts. The difference is how much of your time goes into making them do it — levelling, tuning, failed prints, replacing parts that were cheap for a reason. If your time is worth anything, the mid-range machine is usually cheaper in the end.

Whichever you buy, budget for consumables from day one: filament, a spare nozzle or three, a decent build surface, and somewhere dry to keep the plastic. Those are in parts and accessories and covered in our guides.
