What to consider when buying a 3D printer?
There are a few factors that you should consider when shopping for a 3D printer. These include: • printer resolution – the higher the resolution, the greater the detail of the final model. Bear in mind that high-resolution printers print more slowly than low -resolution 3D printers. • technology – most commercial 3D printers use Fused Deposition Modelling, a process where layers are built up on top of each other. However, some use Stereolithography – where an ultraviolet light beam creates the object from a pool of photosensitive liquid – or Selective Laser Sintering – where a laser is used to melt powder to form an object. • Filament – the filament will determine the materials that can be used. • Printer bed – this will either be heater or non-heated, and will determine that materials that you use. • build volume – this will determine the size of object that the printer can produce. • colour support – some 3D printers can only print one colour in a single job, while others can print multiple colours at once.
