3D Printing

What is 3D Printing?3D printing or additive manufacturing is the creation of three-dimensional solid objects from a digital file by processes in which material is joined or solidified under computer control with material being added together (such as liquid molecules or powder grains being fused together). The creation of a 3D printed object is achieved using additive processes. In an additive process an object is created by laying down successive layers of material until the object is created. Each of these layers can be seen as a thinly sliced horizontal cross-section of the eventual object. 3D printing enables you to produce complex (functional) shapes using less material than traditional manufacturing methods.

Printsyst is a 3D printing personal assistant which helps in the complete 3D printing workflow by uploading the design and giving the instant quotation of the 3D printable files

  • LCD display
  • On-board camera
  • USB, WiFi, Ethernet connectivity
  • Can be controlled remotely via access to Cloud

UltimakerThe Ultimaker family of 3D printers are the most dependable and robust machines the industry has to offer. The Ultimaker offerings have evolved over the years and through diligent engineering have iterated their way to a fantastic and polished machines. As one of the most reliable and capable fully assembled printers available, Ultimaker continues to be an industry leader with the Ultimaker 3 bringing dual extrusion, and the ability to print any filament, to makers and professionals everywhere. Ultimaker printers have changed the world of 3D printing since the initial launch of the Ultimaker Original. They continued to improve the design with the Ultimaker 2 3D printer, updated the extrusion system in the launch of the Ultimaker 2+ and most recently added dual extrusion in the Ultimaker 3.
