3D Printing Starter Kit
Print the thing in your head
There's a particular satisfaction in holding something you've made that didn't exist two hours ago. 3D printing delivers that feeling reliably. A replacement part for something discontinued. A bracket designed for exactly the space you have. A gift made specifically for one person. The first print that comes off the bed looking right is the moment most people understand what this hobby actually is.

Frequently Asked Questions
What's the best first 3D printer to buy in the UK?
The ELEGOO Neptune 4 Pro is our top pick for beginners in 2025. It auto-levels, prints fast, runs Klipper firmware, and is available on Amazon UK with good delivery. The Creality Ender 3 V3 is a popular alternative at a similar price. Both are solid choices; the Neptune 4 Pro edges it for print speed and the quality of the out-of-box experience.
What is bed levelling and why does it matter?
Bed levelling ensures the print nozzle is the same distance from the build plate across the entire surface. If the nozzle is too far away, the first layer won't stick. Too close, and it scrapes the bed or clogs. It's the single most common cause of failed prints for beginners. Most modern printers like the ELEGOO Neptune 4 Pro auto-level, which is the main reason we recommend them. Manual levelling frustrates a lot of new users.
Why won't my print stick to the bed?
The most common causes are: bed not level, bed surface dirty (clean with isopropyl alcohol), printing temperature too low, or a first layer that's set too high in your slicer settings. Clean the bed before every print, run a bed level calibration, and make sure you're printing PLA at around 200–215°C nozzle / 60°C bed. A thin layer of glue stick on the bed surface can also dramatically improve adhesion.
What's the difference between PLA, PETG, and ABS?
PLA is the beginner's filament: easy to print, low temperature, doesn't warp, smells faintly of sweetcorn, and is biodegradable. PETG is tougher, more flexible, and more heat-resistant than PLA, making it good for functional parts. ABS is strong and heat-resistant but warps badly, releases fumes, and needs an enclosed printer. Start with PLA for your first months, move to PETG when you need stronger parts.
What is a slicer and which should I use?
A slicer is software that converts a 3D model file (.STL or .3MF) into the instructions your printer follows (G-code). It controls layer height, speed, supports, infill, and everything else. For the Neptune 4 Pro, Ultimaker Cura is the go-to choice: it has a built-in ELEGOO profile, a clean interface, and is very well documented. It's free to download from ultimaker.com.
Do I need to know CAD to use a 3D printer?
No. You can print for months using free models without designing anything yourself. Printables (printables.com) and Thingiverse have hundreds of thousands of free, ready-to-print models for everything from cable clips to cosplay armour. When you're ready to design, Tinkercad is free, browser-based, and really beginner-friendly. Fusion 360 is more powerful and free for hobbyists.
My print has stringing (thin hairs between parts of the print). How do I fix it?
Stringing happens when molten filament oozes from the nozzle as it moves between sections. The main fix is increasing retraction (the slicer setting that pulls filament back into the nozzle before a travel move). Also try lowering your print temperature by 5°C at a time, and increase travel speed. Most slicers have anti-stringing profiles; enabling 'combing mode' in Cura or Orca Slicer often fixes it straight away.
Is 3D printing expensive to run?
It's very affordable once you have the printer. PLA filament costs £15–£25 per kg, and most small-to-medium prints use 20–150g. Electricity is minimal; most home printers draw 100–250W, similar to a lightbulb. Your biggest ongoing costs are filament and occasional consumables like nozzles (replace every few months with regular use). A nozzle costs about £3–£8.
How long do 3D prints take?
Small prints (keychains, cable clips) take 20–60 minutes. Medium objects take 2–6 hours. Large pieces can take 10–20+ hours. Modern printers like the Neptune 4 Pro are significantly faster than older machines. A print that takes 8 hours on a first-generation Ender might take 2–3 hours on a current-generation printer. You can also start a print and leave the house. Most modern printers have remote monitoring via app.
Is 3D printing safe to do indoors?
PLA is the safest filament for indoor use and emits minimal fumes at standard printing temperatures. ABS and ASA produce stronger fumes and should be printed in well-ventilated spaces or enclosed printers with filtration. As a general rule, keep the room ventilated, avoid sleeping in the same room as a running printer, and don't leave a printer unattended for very long prints if you can help it.
