Easier to print than ABS, and moderately better heat resistance than PLA. Often used in consumer-level printers when creators desire better heat resistance than PLA+ or need more flexibility. ECM Electrochemical machining, a process that uses electricity to chemically machine metal. Commonly used in 3D printed firearms to create DIY barrels ...
In the 19th century, hot stamping became a popular method of applying gold tooling or embossing in book printing on leather and paper. [5] The first patent for hot stamping was recorded in Germany by Ernst Oeser in 1892. [2] From the 1950s onward, the method became a popular means of marking plastic . [4]
