Some of the most interesting and potentially far-reaching developments in additive fabrication are aimed at direct manufacturing of end-use products. Much of the work is at the small end of the size scale and is extremely diverse. Considerable patent activity is being generated in areas such as biological, chemical and industrial instrumentation; integrated circuits; direct write of electronics including displays, batteries and hybrid circuitry - and in many other fields.
Individuals working on these problems not only must develop the materials used and test their results in the final application, but they usually must develop the machinery to make the parts or assemblies, as well. One of the more popular technologies for additive fabrication of small items has been based on various forms of inkjet printing. Now FUJIFILM Dimatix, Inc. of Santa Clara, CA has introduced a versatile inkjet material deposition system aimed at just such applications. |
 material onto substrates up to 50 mm thick. |

The DMP-2800 is a desktop unit measuring 26 x 23 x 16 inches with a printhead that can be positioned in X-Y and theta over an 8 x 11 inch substrate. Substrates up to 50 mm thick can be accommodated and the vacuum platen securing the substrate can be adjusted in temperature up to 60 deg C. The fluid contained in the disposable printhead can also be adjusted in temperature.
The disposable printhead itself is said to be unique. FUJIFILM Dimatix says it’s the world’s first piezoelectric MEMS-based cartridge-style printhead that allows users to fill their own fluids. Each cartridge reservoir has a capacity of 1.5 ml and cartridges can easily be replaced to facilitate printing of a series of fluids. Each single-use cartridge has 16 nozzles linearly spaced at 254 microns (10 mils) with a typical drop size of 10 picoliters.

The unit is said to be compatible with any type of fluid that can be used in an ink jet process, including nanoparticle-based conductive inks used to print RFID antennas, semiconducting organic inks for printing transistors, and photopolymers. Additional options include a drop-watch camera for optimizing droplet characteristics and fiducial camera systems for accurately positioning patterns. Prices start at under US$25,000.
