For anyone who wants to buy a 3D printer at home, the first major decision to make is whether to buy a resin printer or a filament printer. Resin has the advantage of finer details, but filament printers usually produce stronger printing results. In these two main camps, there are various types and sizes to choose from, but thanks to some researchers at the Ecole Polytechnic Institute in Lausanne, Switzerland (EPFL), a new resin printer is coming out, which can be printed almost instantly.
The working principle of the method is similar to that of the existing resin printer, which hardens the resin by irradiating a specific light pattern on the resin. The main difference is that the resin is initially placed in the cylinder and rotates at a high speed, and the light shines on the resin at different angles with very precise intensity and time, so as to harden the resin in a specific area. This high-speed method allows printers to print in record time. In addition to the high price of the prototype, the only drawback at present is that it is limited to small-scale printing.
With the future expansion capacity and the downward trend of the price of most new technologies after a period of time on the market, if such printers can be expanded, it will be a breakthrough to print at this speed. Especially if they eventually match the size and scale of domestic printers such as this resin printer.
