Una stampante 3D con il piatto di stampa suddiviso in tanti elementi quadrati di qualche centimetro di lato che si possono sollevare indipendentemente uno dall’altro. In questo modo si adatta al profilo dell’oggetto da stampare e riduce di molto il tempo e lo spreco di materiale per i supporti.

Esperimenti fatti con una normale stampante 3D a fusione passando con diversi tipi di pattern su fogli di diversi tipi di plastiche. Si creano cosi punti di fusione, dove c’è stato contatto con l’estrusore, e intercapedini. Nelle intercapedine viene poi soffiata aria per ottenere forme 3d ed oggetti che si muovono.

Thomas Edison talked about bugs in electrical circuits in the 1870s. When the first computers were built during the early 1940s, people working on them found bugs in both the hardware of the machines and in the programs that ran them. DESCRIPTION In 1947, engineers working on the Mark II computer at Harvard University found a moth stuck in one of the components. They taped the insect in their logbook and labeled it "first actual case of bug being found." The words "bug" and "debug" soon became a standard part of the language of computer programmers. DESCRIPTION Among those working on the Mark II in 1947 was mathematician and computer programmer Grace Hopper, who later became a Navy rear admiral. This log book was probably not Hopper's, but she and the rest of the Mark II team helped popularize the use of the term computer bug and the related phrase "debug."
