3D printing for beginners: start to finish

Most advice about 3D printing answers one question at a time: which printer, which filament, which settings. What a beginner actually needs is the order to do things in, and permission to ignore most of what the listings shout about. This is the whole path from “I think I want one” to a shelf of things you made, with a link to the detailed guide at every step.

The short version: buy a self-levelling filament printer in the £200–£300 range, order two spools of PLA with it, print something small and useful in the first hour, and do not buy anything else until a specific problem asks for it.

Step 1: decide what you want to make

Everything else follows from this, so be honest about it. There are two kinds of home 3D printer and they suit different people.

• Useful things, toys, household parts, props — a filament (FDM) printer. This is most people. Prints come off the bed ready to use, the plastic is cheap and safe to handle, and failures are easy to understand.
• Miniatures, figurines, jewellery, fine detail — a resin printer. The detail is far beyond anything filament can do, but every print must be washed and cured, the resin needs gloves and ventilation, and the waste needs careful disposal.
• Not sure, or buying for children — filament.

The full comparison is in FDM vs resin. The rest of this guide assumes filament, because that is where nearly everyone should start; if you choose resin, read resin safety before anything else.

Step 2: choose the printer

Listings compete on top speed and headline features. What decides whether you enjoy the machine is how quickly you get a good first print and how rarely it fails afterwards. Four things deliver that:

• Automatic bed levelling. The first layer is where most beginner prints fail, and this is the feature that makes those failures rare. Do not buy a printer without it. See auto bed levelling.
• It arrives assembled. A kit can be built slightly out of square and cause problems you chase for weeks.
• Tested slicer profiles from the manufacturer, so you are not tuning settings you do not yet understand.
• Spare parts you can buy in the UK. Nozzles and build plates wear out.

And four things matter much less than they sound:

• Top speed. A figure such as 600 mm/s is a best case. Real prints run far slower on every machine.
• A huge build volume. Around 220–256 mm covers nearly everything. See how big a build volume do you need.
• An enclosure, unless you will print ABS or ASA. See enclosed vs open frame.
• Multi-colour, unless colourful prints are the reason you are buying. It costs more and wastes filament at every colour change. See is multi-colour worth it.

How much to spend

The detail behind each band is in how much to spend on a 3D printer, and the full list of what to look for is in how to choose your first 3D printer. To skip straight to a recommendation, the printer finder asks a few questions and names a printer from our reviews at today's price.

Step 3: what to order with it

Less than you think. A complete first order is:

• Two 1 kg spools of PLA or PLA+, 1.75 mm, from the same brand: one grey or black, one in a colour you want.
• A spare nozzle of the type your printer takes.
• A sealed box and some desiccant to keep opened filament dry.

That is about £30–£50 on top of the printer. Do not buy a 4 kg bundle, a filament dryer, a set of twelve colours, upgraded parts or a tool kit yet. Most printers ship with the few tools you need, and the rest should wait until a specific problem asks for them. The reasoning is in your first filament order, are filament bundles worth it and how many colours do you need.

Step 4: which filament for your first project

Start with PLA whatever you plan to make, because it is the easiest material to learn on. Once you know the machine, match the filament to the job:

The material choices are covered in PLA vs PETG, printing with TPU, silk filament, glow in the dark filament and high-speed PLA. On the filament page, hovering over any material or finish shows what it is best for.

Step 5: what to print first

Print in this order. Each one teaches something, and none takes long.

• 1. The test file that came with the printer. It was sliced by the manufacturer for that machine, so if it fails, the problem is setup, not you.
• 2. A small calibration model. A test cube or the classic small boat. It confirms the first layer, dimensions and overhangs in under an hour.
• 3. Something small you will actually use. A cable clip, a hook, a phone stand. Twenty to forty grams, and proof that the thing is useful.
• 4. A print-in-place toy. An articulated animal or a fidget that comes off the bed already moving. This is the print that shows what the machine can do, and the one to make in your second, more exciting spool.
• 5. Something for the printer. A tool holder, a spool holder, a cable guide. A printer improving itself is a rite of passage.
• 6. A real project. Modular drawer organisers, a set of wall hooks, a gift. Something with several parts that takes a few evenings.

All of these are free to download. The sites to use, how to tell a model that prints from one that only looks good in a render, and what the licence lets you do are in where to find free 3D models.

Step 6: get the first layer right

If you learn one skill, make it this. A correct first layer prevents most failed prints, most warping and a good share of the problems people blame on cheap filament. On a self-levelling printer it is mostly automatic, but three habits still matter:

• Keep the bed clean. Fingerprints are grease, and grease stops prints sticking. Wash the plate with warm water and washing-up liquid.
• Learn what a good first layer looks like: lines slightly flattened and touching, with no gaps.
• Let the bed cool before removing a print. Most parts release on their own, and you never need a blade.

See first layer calibration, bed adhesion and print removal.

Things to look out for when buying

• The discount is against a price nobody paid. Printers are on offer almost constantly. Judge today's price against the printer's own history, which every printer page on this site shows. See is it really a good deal.
• Combo or printer only? Multi-colour bundles share photos and listings with the bare printer. Check what is in the box.
• Near-identical names. A1 and A1 mini, 5M and 5M Pro, Mono 4 and Mono 4 Ultra are different machines at different prices.
• Pooled reviews. One star rating can cover several variations of a listing, so it may not describe the exact product you are buying.
• The price belongs to another variant. On filament especially, the price shown can be for the smallest pack on the page. Select the variant, then read the price again.
• Spool count is not weight. “10 rolls” may be ten 250 g spools. Compare price per kilogram.
• Proprietary parts. Printers with their own quick-swap nozzles usually cost more per nozzle than those taking standard ones.
• Labels with no standard behind them. “High speed”, “PLA+” and scanner accuracy figures are all self-declared.
• Open-box stock. Often excellent value, but check the condition note for missing parts and whether the warranty still applies.

The common mistakes

Nearly everyone makes several of these. Knowing them in advance saves a few weekends.

Buying

• Buying the cheapest printer. A printer that saves £40 and fails one print in five costs more in time and wasted filament within a month.
• Buying on speed or size. You will use neither as much as you expect. Reliability is the specification that matters.
• Buying a printer that does not level itself. The one false economy with no upside.
• Buying a 4 kg bundle before the first print. You do not yet know whether that brand suits your machine.
• Buying every colour. A kilogram is thirty-odd small prints. Most colours go damp before they are finished.
• Buying upgrades for problems you do not have. Fix what is actually going wrong, one thing at a time.

Printing

• Starting with a difficult material. PETG, TPU and ABS each add a second variable. Learn on PLA.
• Changing five settings at once. When the print improves you will not know why, and when it gets worse you cannot undo it. Change one thing, print, compare.
• Blaming the filament first. Most adhesion and quality problems are the first layer or a dirty bed.
• Printing too fast too soon. Slowing down fixes more problems than any other single change.
• Touching the build plate. Handle it by the edges.
• Letting go of the filament end. It slips under a neighbouring wrap and ties a knot that jams hours into a print. Always clip it or thread it through the spool. See spool holders.
• Leaving filament out for weeks. It absorbs moisture and prints worse. See filament storage.
• Printing a large model before a small one. A ten-hour first print that fails at hour nine teaches very little.
• Downloading a model on the strength of a render. Look for photos of real prints from other people.

Damage and safety

• Using a metal scraper or a knife on the bed. It gouges the surface, and a slipped blade is the most common injury in the hobby.
• Running abrasive filament through a brass nozzle. Glow in the dark, carbon fibre and glitter wear it out quickly. See hardened vs brass nozzles.
• Leaving PLA prints in a hot car. They soften and sag.
• Printing ABS in an unventilated room.
• Handling resin without gloves, or pouring wash liquid down the sink. Both are the serious mistakes of resin printing.

What it really costs

After the printer and the £30–£50 of extras, the running cost is mostly filament, and it is lower than people expect: mainstream PLA is about £10–£20 per kilogram and a typical print uses tens of grams, so most objects cost well under £1 in plastic. Electricity adds pennies. The cost nobody lists is failed prints, which is the real argument for a reliable printer. See the real cost of owning a 3D printer.

What to buy later, and when

• When prints are hard to clean up: flush cutters and a deburring tool. See finishing tools.
• When parts need to fit each other: digital calipers. See calibration tools.
• When you mostly print functional parts: a 0.6 mm nozzle. See nozzle sizes.
• When you try an abrasive filament: a hardened steel nozzle.
• When PETG tears at your build plate: a textured plate. See build surfaces.
• When you move on to PETG, TPU or nylon: a filament dryer. See do you need a filament dryer.
• When you know which colour you run out of: a multi-kilo bundle of it.

Questions people ask

What do I need to start 3D printing?

To start 3D printing you need a printer with automatic bed levelling, two 1 kg spools of PLA filament, a spare nozzle, and a sealed box with desiccant to keep the filament dry. Free slicer software and free models cover the rest. Budget about 200 to 300 pounds for the printer and 30 to 50 pounds for the extras.

What is the best 3D printer for a complete beginner?

The best 3D printer for a complete beginner is a filament printer that levels its bed automatically, arrives assembled, and comes from a brand with tested slicer profiles and UK spare parts. Most first-time buyers are best served in the 200 to 300 pound range. Reliability matters far more than top speed or build volume.

What should I print first on a new 3D printer?

Print the test file supplied with the printer first, then a small calibration model, then something small and useful such as a cable clip or phone stand. After that, a print-in-place articulated toy shows what the machine can do. Leave large, multi-hour prints until the small ones come out well.

What filament should a beginner use?

A beginner should use PLA or PLA+ in 1.75 mm. PLA is the easiest filament to print, needs no enclosure, and fails in ways that are easy to diagnose. Buy two 1 kg spools from the same brand, one grey or black and one in a colour you like, and try PETG or TPU only after you know the printer.

What are the most common 3D printing mistakes beginners make?

The most common beginner mistakes are buying a printer without automatic bed levelling, starting with a difficult material instead of PLA, changing several settings at once, printing too fast, touching the build plate with greasy fingers, and leaving filament out to absorb moisture. Most early print failures come from the first layer or a dirty bed, not from the filament.

How much does it cost to get started with 3D printing in the UK?

Getting started with 3D printing in the UK costs roughly 230 to 350 pounds: about 200 to 300 pounds for a good first printer and 30 to 50 pounds for two spools of filament, a spare nozzle and a dry box. Capable starter printers begin at around 150 to 200 pounds. Running costs afterwards are mostly filament.

Is 3D printing hard to learn?

3D printing is much easier to learn than it used to be. A modern printer with automatic bed levelling can produce a good first print within an hour of unboxing. The skills worth learning early are recognising a good first layer, keeping the bed clean, and changing one setting at a time when something goes wrong.

Do I need to know how to design 3D models?

No, you do not need to design 3D models to use a 3D printer. Millions of ready-made models are free to download from sites such as Printables, MakerWorld and Thingiverse, and many owners never design anything. Learning basic CAD becomes useful when you need a custom part that nobody has already made.

Which filament should I use for fidget toys?

Use PLA+ for fidget toys, ideally in a dual-colour or rainbow finish. PLA+ is tougher than standard PLA at the thin hinges that print-in-place toys rely on, and colour-shifting finishes show well on moving parts. Standard silk filament looks striking but bonds more weakly between layers, so choose designs with generous clearances.

Should I buy a filament or resin printer first?

Buy a filament printer first unless you specifically want miniatures or very fine detail. Filament prints are strong, cheap and ready to use straight off the bed. Resin gives much finer detail but every print must be washed and cured, and the resin needs gloves, ventilation and careful disposal.

What should I avoid when buying a 3D printer?

Avoid printers without automatic bed levelling, kits that need full assembly, and brands with no UK spare parts. Do not judge a deal by the percentage off, because the reference price is often one the printer rarely sold at. Check whether a listing is the bare printer or a multi-colour combo, and confirm the exact model name.
