SUSS MicroTEC PixDro LP50 Inkjet Printer

The PiXDRO LP50 is a desktop R&D inkjet printer and is designed for research and development of inkjet processes, applications, and the evaluation and development of inkjet materials. The printer is designed for a wide range of applications such as semiconductor packaging, PCBs, printed electronics, photovoltaics, displays, and for biomedical purposes.


nScrypt 3Dn-300 Direct Write Quad-Head Printer

The 3Dn Series Factory in a Tool is a high-speed platform for 3D manufacturing products and contains automatic tool changes, a palette of more than 10,000 materials, and post-processing options. This digital manufacturing system can go from CAD to a completely finished electronic product utilizing automatic tool changes to 3D print and house a structure with the extrusion tool head. The printer is a Tabletop Model that operates on a precision ball screw motion platform and is capable of microdispensing; high-precision 3D printing; micro-milling, drilling, and polishing; and pick and place. 


Xenon X-1100 Photo-Sintering System with Flatbed Capacity

The X-1100 system possesses the latest advances in Pulse Light technology. It provides researchers with photonic technology to produce high-intensity light that can be used in a large variety of new applications. Features of the X-1100 include a benchtop design, high-intensity light containing up to 9 Joules of radiant energy, and multiple user screens. Additionally, the system offers a wide spectrum of light (deep ultraviolet, visible, and far infrared) and its benchtop design also allows the X-1100 to connect to voltages from 90 to 250 Vrms. 


Lamination Encapsulation for FHE

The Lamination Encapsulation machine provides protective coating on the flexible hybrid electronics (FHE). Encapsulated items are completely waterproof whereas their laminated counterparts are not fully covered. The machine is built from substantial metal parts and its high-powered motor can successfully process heavy duty FHE.
