3D printers and 3D pens
3D printers and 3D pens let you build physical objects out of plastic - from prototypes and spare parts to models and craft projects. This category includes desktop 3D printers for home or a small workshop that build objects layer by layer, plus 3D pens for freehand drawing in the air, which can suit children under adult supervision too. When choosing a printer, check the type of plastic it uses, the build area size, and positioning accuracy.
