Abstract
Multi-Jet 3D-printing is a method of printing similar to inkjet printers. The print head on these printers has 40 jets which use piezo-electric actuators to open an orifice allowing liquid material to be dispensed in the desired area. The ProJet series of printers from 3D Systems use Selar containers to hold the wax print-material. An issue occurred with the printer where the jets would clog and misfire causing very bad prints. It was hypothesized that the Selar was melting and leaching into the wax and getting stuck in the jet. New Nylon containers were created to test whether the theory was correct. The printers were stressed every day with prints and then Drop masses were run as a test. The Nylon bottles accompanied by built-in processes were able to mitigate the issue and bring the printers close to expected quality.
