Polyjet Technology

Polyjet printing continues to utilize innovative and new approaches in 3D prototyping hardware, software and fabrication materials. Polyjet printing and a function of rapid prototyping technology is a design process using computer programming to guide the creation of a three dimensional model through the layering of fabrication material. The Polyjet heads deposit fabrication material in a building tray layer by layer and with concise precision until the prototype is built to complete specifications. Polyjet printers are able to use many different types of fabrication materials to build models and prototypes. Polyjet technology uses resins, polymers or photopolymers either singularly or in different combinations to build many different types of models.

Polyjet printing techniques utilize computer assisted design (CAD) which guides the building process step by step and ensures the correct construction of even the most complex of prototype designs. Polyjet printing heads are able to layer precise amounts of fabrication material during the layering process and build prototypes rapidly and accordingly to design specifications. During various stages of the Polyjet building process ultra-violet lights cure the fabrication materials which harden and produce a functional model or prototype. The Polyjet printing process is simple and easy including setup, printing and cleaning of the prototype model or product. Polyjet techniques for producing prototypes assist engineers in solving complex design issues early on in the development process.

Polyjet Advancements

Polyjet technology advancements are assisting designers to solve even the most complex design issues in the production of prototypes. A wide range of design flexibility is available to engineers with Polyjet printing techniques that were not previously available. Advancements in the computer assisted production of models now permits design changes to be implemented during any stage of the process. With the introduction of new polymer fabrication materials and the ability of Polyjet printers to utilize multiple materials in a single prototype project, designers can engineer many new features into their prototypes and models.

The introduction of advanced Polyjet technology allows the production of prototypes using thinner building lines, innovative fabrication materials and design accuracy. Polyjet printing technology continues to advance the ability to produce high quality and sophisticated prototypes. Polyjet printers are easy to program, set-up and rapidly produce prototypes. Instant and fully cured prototypes which need little post production work make Polyjet printing technology faster and very cost efficient for today’s competitive businesses and companies.
