Thanks to the generosity and hard work of Uncle Fred we now have a fully functioning 3D printer at home! Fred bought it in kit form, as a Christmas present for us and the Applins together. It took a lot of setting up. The provided instructions were vague and incomplete, but Fred and the boys persisted and used their ingenuity and resourcefulness to fill the gaps. Below are some pictures of things the boys have printed.
These have been designed and drawn up as CAD files by someone somewhere, and uploaded for free use. The printer's "ink" is a spool of plastic filament that is melted and laid down by the roaming printer head, controlled by the three robot arms. It's all incredible really.
