The Polyjet Matrix process works similar to the Polyjet 3D printing process.
Objet’s patent-pending PolyJet Matrix technology works by jetting two distinct Objet FullCure® photopolymer model materials in preset combinations.
The dual-jet process can combine materials in several ways, enabling the simultaneous use of two different rigid materials, two flexible materials, one of each type, any combination with transparent material, or two jets of the same material.
Each material is funneled to a dedicated liquid system connected to the PolyJet Matrix block, which contains 8 printing heads. Two perfectly synchronized printing heads are designated for each material, including the support material.
PolyJet Matrix Technology controls every one of the 96 nozzles in every print head. Preset composites of model materials are jetted from designated nozzles according to location and model type, providing full control of the structure of the jetted material and hence of its mechanical properties. This enables each composite material, called a “Digital Material”, to provide specific values for tensile strength, elongation to break, HDT and even Shore A values.
The materials are jetted in ultra-thin layers onto a build tray, layer by layer, until the part is completed. Each photopolymer layer is cured by UV light immediately after it is jetted, producing fully cured models that can be handled and used immediately, without post-curing. The gel-like support material, which is specially designed to support complicated geometries, is easily removed by hand and water jetting.
Dedicated Objet Studio for Connex™ software manages the process, handling multi-material STL files and creating files that combine different materials, assemblies and model characteristics.
Polyjet Matrix Technology expands the range of materials available for 3D printing. These multi-phase composite materials are created by combining different FullCure materials. Different variations of materials will yield a new material with different physical properties and mechanical capabilities. The original materials are altered to reflect the desired shore values, tensile strength and flexural strength.
