You probably know that high end industrial 3d printers can print metal objects by using laser or electron beams on fine metallic powder but Vader is something completely different. Vader aims at small companies or professional workshop environments by implementing proprietary Magneto Jet Printing (MJP) and magneto hydro dynamics (MHD) ceramic print head technologies to reduce the machine cost.

It uses molten metal and jets it in small droplets onto a surface similarly to a standard ink jet paper printer and by connecting the metal droplets a 3d object can be made. It could be considered world’s first molten metal 3d printer! Since one of the design ideas behind this machine is to make it widely available, the material it uses had to be widely available and cheap so the main material is molten aluminum wire.

While the basic technology sounds easy in theory and has been used even 20 years ago in the past for some applications, there are still many difficult technical obstacles to overcome. These obstacles include reaching complex requirements like developing a print head that is resistant to abrasive properties of molten aluminum by using ceramics, magnetic containment and getting drop-on-demand molten metal droplets.

Vader is founded two years ago by Scott and Zachary Vader , a father-son team. With Fall of 2015 being the time frame for the release of first working pre-production Mark 1 prototype. The price range of the first machine should be around 250.000 US .D which is much cheaper than currently available commercial metal 3d printers.

Hopefully the Vader team will be successful in bringing their machine to the market and start the race for affordable metal 3d printers. I want one! And I know some of you want one too! Vader Systems company page: Star http://www.vadersystems.com/

A printed circuit board (PCB) mechanically supports and electrically connects electronic components using conductive tracks, pads and other features etched from copper sheets laminated onto a non-conductive substrate. Components (e.g. capacitors, resistors or active devices) are generally soldered on the PCB. Advanced PCBs may contain components embedded in the substrate.
PCBs can be single sided (one copper layer), double sided (two copper layers) or multi-layer (outer and inner layers). Conductors on different layers are connected with vias. Multi-layer PCBs allow for much higher component density.

FR-4 glass epoxy is the primary insulating substrate. A basic building block of the PCB is an FR-4 panel with a thin layer of copper foil laminated to one or both sides. In multi-layer boards multiple layers of material are laminated together.

Printed circuit boards are used in all but the simplest electronic products. Alternatives to PCBs include wire wrap and point-to-point construction. PCBs require the additional design effort to lay out the circuit, but manufacturing and assembly can be automated. Manufacturing circuits with PCBs is cheaper and faster than with other wiring methods as components are mounted and wired with one single part.

A minimal PCB with a single component used for easier modeling is called a breakout board.  The making of DIY circuit boards is a complex task. First, you’ll have to plan the PCB, make a 2D print of the layout, cut a copper plate, transfer the PCB layout to the copper plate, iron the circuit, go through the process of etching, cleaning, disposing… and after some hours of manual labor, you should be ready.

There must be a way to do this more efficiently, right? Wouldn’t a 3D printer be perfect for that job? Fortunately, the first PCB 3D printers will become available soon. Currently, these machines are able to 3d print electronics.

1. 3D Printed Electronics in One Go: Nano Dimension Dragonfly
The “NexD1” is a multimaterial 3D printer from a German company called Next Dynamics. Their Kickstarter campaign wants to deliver more than a 3D printed circuit board. Thanks to the “DigiJet” technology, the NexD1 is able of print a wide range of materials, including resins with nano-particles or pigments. Therefore you can 3D print not only circuit boards, but also full-color prints and flexible materials.

The NexD1 prints fully functional PCBs and places them in any 3D configuration. According to the team, this is made possible by galvanizing a nano-particle infused resin – a new and interesting way of electronics manufacturing that opens up a new realm of potential in 3D prototyping.

This type of printer that is a very powerful printer that can print and produce a three-dimensional product. 3D printers are widely used in various industries such as health, art, architecture, and other industries much. The materials used in the three-dimensional printers use special materials for three-dimensional printer. And media used for the manufacture of three-dimensional model is a special material, so can not use just any material.
This section presents the 3D design printed free-form speaker based on the principles of sound reproduction electrostatic (ESR). It discusses the principles of operation and design them and then outlines the basic categories of 3D printed speakers investigated in this paper. We discuss the details of the fabrication technique of the speakers, their properties, and report their experimental evaluation. Electrostatic Sound Reproduction basic principle of electrostatic sound reproduction aresimple and explored in depth in the 1930s. Conductive thin diaphragm and plate electrodes are separated by material, for example, the air insulation, the dielectric permittivity ε (Figure 2a). The audio signal is amplified to ~ 1000 V and is applied to the electrodes, charging relative to the ground is connected to the diaphragm. As the charging electrode, an electrostatic attraction force is developed between the electrodes and the diaphragm

3D Printed Speaker Design Space
3D printed speaker can take many shapes and forms which leads to many unique applications. Figure 4 explores some forms that become possible with the technology of printed speakers. It is clear that we can make the traditional flat planer speaker (Figure 4, above) are common these days and that has been explored before. Therefore, we did not explore these categories speaker in this paper. At the next level of complexity speaker can take a variety of basic 3D geometric shapes including traditional speaker coneshaped, cylindrical, spherical and others (Figure 4, middle).

All these forms produce sound in all directions around the speaker, ie, omnidirectional sound production. Note that the speaker geometric design a 3D using traditional speaker technology challenge. By using our 3D printed speaker approach, however, designing various geometric speaker is relatively trivial problem. We'll talk about it in the newspaper. Aspects of the most challenging and important than 3D printed speakers is that hey are integrated into objects of arbitrary shape, being part unobtrusive and invisible from their design (Figure 4, below). 3D printed speaker technology provides an alternative to traditional techniques integrate loudspeaker functions into objects and said .

Diaphragm Design for 3D Printed Speakers
The main factors affecting the quality of printed speakers is the design of the diaphragm. Figure 5 presents the measurement results for two diaphragm displacement 3D printed with a thickness of 1.0 mm and 0.5 mm and a weight of 5.94 g and 3.65 g, respectively, driven by a sinusoidal signal of 100 Hz. The LK-H057 Keyence® laser displacement sensor is used to measure the movement of the diaphragm at a sampling rate of 20 kHz with an accuracy 0.025 m. In addition to displacement, a Extech® 407 730 Sound Level Meter (SLM) is used to measure the sound pressure level (SPL) 30 cm from the speaker. Experiments show that the speaker a) printed work as designed, and b) lighter and thinner diaphragm produces significantly greater displacement and sound for louder.

In fact, the movement almost doubled when we reduce the thickness of the diaphragm half. speaker emitted energy increases with increasing displacement, which is supported by measurements resulted in 54.8 and 53.2 dBSPL dBSPL for 0.5 mm and 1.0 mm diaphragm using 2 kHz input signal. The last observation, while seeming simple, are not clear. As the diaphragm becomes thinner, they have also become much more flexible. Initially it was not clear to us that the thinner, but more flexible, diaphragm will outperform a slightly thicker and stiffer. Experiments show that the stiffness of the diaphragm is not as important as the thickness and weight. This discovery allows us to significantly expand the range of materials and processes that can be used to create 3D printed diaphragm effective for speaker.
