Rapid prototyping is neat, fast and cost-effective with cartridge-dispensed polyurethanes. The 400 ml cartridges can be filled with premeasured amounts of resin and hardener in either a 2:1 or 1:1 ratio. Filled cartridges are then ready to be installed in a DS-400 pneumatic dispensing gun along with a static mixing nozzle that ensures thorough system blending. When the gun handle is depressed, resin and hardener are mixed in the disposable nozzle and can be dispensed into the mold.

Polyurethanes formulated with convenient 1:1 and 2:1 mix ratios can be used with cartridges. Low viscosities facilitate filling, mixing, dispensing and application.
