Key Aspects of Polyjet 3D Printing
Polyjet 3D printing is a versatile 3D printing technology that produces outstanding detail, excellent surface smoothness, and accuracy. It is an ideal technology for prototyping, modeling, and production in multiple materials and colors. It uses UV rays which is why photopolymer resins is widely used for printing. Polyjet 3D printing technology is the best alternative for creating high-precision models, and all types of manufacturing tools. Due to its feasibility to incorporate multiple materials and colors in one single part, and faster printing, Polyjet 3d printing services is gaining popularity among a broad spectrum of industries.
Polyjet 3D printing process
Polyjet printer has built-in software that cuts 3D models into several digital images layer by layer. Before sending the 3D file for printing, the print head of the Polyjet printer is placed over the build platform. This print head has several nozzles and a UV lamp to drop material on the platform and cure with UV light simultaneously. When printing starts, the print heat moves over the build platform and starts dropping droplets of polymer resins that are instantly cured by ejecting UV light. When one layer of printing is done, the platform is shifted down as per the setting, which could be between 16 to 32 microns. The next layer then comes up and printing is repeated until the object is 3D printed in whole.
The only thing about Polyjet is, it requires a support structure to stabilize the overhanging features and prevent the nozzles from dropping materials on unintended places. The support structure is stabilized with gel-like material, which is washed away after printing is done. The Polyjet 3D printing process works best with a multitude of materials and has hence, become the most-preferred 3D printing services India.
Use of Polyjet 3D printing
Polyjet 3D printing can be used for creating high-resolution and precision prototypes and production. It offers <0.1 tolerance, and the 3D printed models do not shrink or wrap for a longer time. It is also apt for investment casting where small details and smaller parts are required. You can use Polyjet 3D printing for creating manufacturing tools, biodegradable surgical products, prototypes, and finished products. It is the best technology to print 3D models in multiple colours.
