Document Summary
Gcm 750 | week 2 - the consumer 3d print movement. Start with a block of material (wood, plastic, metal) Cut away until you have the part. Machining, cnc, routering, laser cutting, drilling, lathing, welding assemble or press fitting. Left with a pile of offcuts as waste. An object is created by starting with nothing and adding material a layer at a time until the object is completed. Main 2 types of fdm/fff 3d printers: cartesian. Each element moves only in one direction: delta. Printer head can move in any direction quickly https://www. 3dnatives. com/en/four-types-fdm-3d-printers140620174/ The selective compliance assembly robotic arm (scara) is a very precise system with a tiny footprint. A scara 3d printer looks and moves much like an industrial robot on a car assembly line might. Similar to the cartesian, except that the coordinate sets describe points on a circular grid rather than a square.
