3D printers represent one of the most innovative and interesting technologies to enter both the business world and the hobbyist sector in decades. This 3D printing guide compares a range of 3D printers to help you choose the most suitable device for your requirements.
What is a 3D Printer?
Put simply, 3D printers are computer-controlled fabrication devices. A wide variety of objects designed and defined within software can be created in three dimensions within the printing device from different plastics and polymers - the possibilities depend on the size and model of printer used. Our guide to 3D printers covers everything from the basics to advanced concepts.
The objects are formed via the rapid addition of multiple layers of material, each covering the previous layer. The printing material is applied via a nozzle called an ‘extruder’. It is supplied as lengths of filament which become soft and moldable when heat is applied and then solid again once they have cooled. This construction process accounts for another term used to describe 3D printing in an industrial context - additive manufacturing.
3D printers allow the rapid and flexible production of prototypes, models, spare parts and many other items across the industrial, commercial and even domestic spheres. Models available range from high capacity designs intended for the factory floor right through to small and affordable 3D printers for home use.
Designs intended for printing are normally created in 3D printing software as CAD (Computer-Aided Design) or AMI (Amazon Machine Image) files. These precisely define the dimensions of the object to be built and many designers make their creations available for download and reuse.
Before printing can take place, the CAD or AMI file describing the 3D object must be converted into the programming language G-code, which will be directly readable by the device. The conversion is undertaken by 'slicer' software.

Top 3D Printer Brands
In the rapidly evolving world of additive manufacturing, identifying good 3D printer brands is crucial. Here are some of the best 3D printer manufacturers on the market:
How Do You Use a 3D Printer?
1. Prepare Your Build Plate
The build plate is the area where your item will be built. It is important to ensure the plate adheres firmly to the bed beneath it.
2. Select Your Filament
Various materials are available, each with specific strengths. Two of the most widely used are ABS (Acrylonitrile Butadiene Styrene) and PLA (Polylactic Acid). Both are thermoplastics (plastics which become malleable when heated then solid again when they cool). PLA is made from corn starch or sugarcane and is biodegradable.
3. Switch on Your Printer and Allow it to Heat
Different filaments require specific heat settings, so make sure to familiarise yourself with these.
4. Load the Filament
The precise loading process varies but it is normally necessary to heat the extruder (filament nozzle) to a specific temperature, apply a release lever and then insert a length of filament. It is not uncommon to see melting filament begin to protrude through the extruder.
5. Ensure the Bed is Correctly Positioned
An uneven or incorrectly positioned bed can lead to inaccurate or uneven prints. As a result, it's important to ensure that the bed supporting the build plate is level and positioned at the correct height. Some 3D printers require manual levelling, while others have an automatic mechanism for this.
6. Input Required Information
You will need to measure the height and level and type these into the printer software in order to define the precise gap between the nozzle and the build plate.
7. Start Printing!
Once you've completed the above steps, all that's left to do is to open your G-Code file and begin printing!
