Materials science. ABS and PLA. Acrylonitrile Butadiene Styrene. (. ABS. ) was the most popular material used to print first 3D models few years ago and it is extremely popular now as well. This material is very durable, slightly flexible lightweight and can be easily extruded, which makes it perfect for 3D printing. It requires less force to extrude than when using PLA, which is another popular 3D filament. This fact makes extrusion easier for small parts. The disadvantage of ABS is that it requires higher temperature than for example PLA material. Its glass transition temperature is about 105°C and temperature 210 – 250°C is usually used for printing with ABS materials.. Luminous:. an object that emits/produces its own light (. eg. . sun). Non-luminous:. an object that do not produce its own light and is visible due to reflected light (. eg. . a tree). Sources of light. Humphry Davy created the first incandescent light by passing current through a platinum strip. It caused a glow and did not last long, but marked the beginning of incandescent light development. Experimenters continued over the next 70 years to use platinum and iridium. Frederick used a platinum filament in an evacuated glass tube to make a light bulb. . Joran. Booth and Peter Hyatt. ME 340.
