Polyjet

Material Jetting

During the pre-processing, the software automatically calculates the placement of photopolymers and support material from a 3D CAD file. During the printing, the resin 3D printer jets and instantly UV-cures tiny droplets of liquid photopolymer. Fine layers accumulate on the build tray to create several highly-detailed 3D printed products. Where overhangs or complex shapes require support, the Polyjet 3D printer jets a removable support material, named FullCore 750. The process of fine layer polymerization is repeated until the object is finished. After the photopolymerization is completed, the batch is placed under a pressurized water jet. This allows any excess liquid or supports to be removed with a few human interactions. The final product has a naturally smooth surface which can be polished further to create near full transparency for the clear resin. 3D printed models and parts are ready to handle and use right out after the cleaning process, there is no need for post-curing.

When to use Polyjet?

Applications
Polyjet printing is mostly preferred by automotive, electronics, and consumer goods companies. Companies that are engaged in clothing manufacturing and medical development also choose Polyjet over other printing technologies. This is all because printed prototypes look extremely realistic and closely resemble finished products.
Pros of Polyjet
Polyjet has very high accuracy and resolution. Its printing results in very smooth surfaces of parts, and different materials can easily be combined. Also, lines of fine layers can easily be removed.
Cons of Polyjet
One disadvantage of Polyjet is that it is quite expensive compared to other 3D printing technologies. Also, sharp edges become slightly rounded when printed with Polyjet. And lastly, the use of support materials creat changes in the quality of surfaces, in that when there is not support, the surface quality is glossy and smooth, while when there is support, the surface quality becomes dull and rougher than usual.

Fun Fact
Objet Geometries Ltd. is a company founded by Rami Bonen, Gershon Miller, and Hanan Gotaiit in 1998. The Multijet Modeling or more commonly known as Polyjet was developed by Objet. It presented and released to the market the very first multi-material 3D printer after being about ten years in the industry. The year 2012 became a remarkable year for the company as it was the year when they released the first 3D printer with more than 100 combined materials, and in the same year, Objet made a huge decision when it merged with another industry giant, Stratasys.
