Property Estimate for Inkjet based Direct Digital Manufacturing
Abstract. Nowadays, additive manufacturing (AM) is one of the easiest, fastest and most flexible technology for turning 3D design into a real object without machining, molding or assembly. There exist many kinds of AM technologies including selective laser sintering (SLS), stereolithography (SLA), Fused Deposition Modeling (FDM), InkJet Printing, etc. Common materials include aluminum, steel alloys, precious metals, plastics, etc. Common AM technologies include FDM, SLA and InkJet Printing. Despite the most updated FDM technology can produce models with up to four colors, most of the FDM machines can only produce plastic objects with 1-2 colors and materials. Although SLA can produce polymer objects with high precision, the fabricated objects are usually in single color and material. In order to fabricate an object with different colors and materials, Inkjet based direct digital manufacturing (DDM) is one common solution. DDM is the process of using a 3D digital CAD model for directly fabrication without the need for process planning. There are several major Inkjet based DDM such as 3D printing (3DP) and MultiJet Printing (MJM) are developed by MIT, while PolyJet and PolyJet Matrix are developed by Stratasys. However, most of the Inkjet based 3D printers can only support a few colors and materials. PolyJet Matrix type technology not only able to fabricate multiple color objects, it can also fabricate object with range of material options, and can even combine several materials into a single 3D printed model.
