RepRap iForm 181 photopolymer resin is specially designed for printing on LCD printers. The illumination power on such printers is less than on SLA printers, so the resin is more active. This allows for reduction of the exposure time per layer to 6 seconds, which allows for printing of models very quickly, without loss of quality. The resin maintains a balance of stiffness and elasticity, which makes printed models very durable, and the printing of small parts is very accurate. The resin is perfect for printers with a 405nm long beam.
