We have applied to Create The Future Design Contest 2016 You can vote for it in the contest website Design Contest 2016by ingpconci - Let's design something! (I've got an idea ...)
Hi, I can confirm that the developments continue. There are some issues about the actuators but we are working on developing a dedicated microfabrication process. In the next month we will apply for a technical competition and we hope to win the first prize in order to start with the microfabrication process. Paoloby ingpconci - Let's design something!

I think an extruded area in the center of the nozzle. Have you some suggestion about the H and L dimension? What is the minimum acceptable values for H?by ingpconci - Let's design something! (I've got an idea ...)
To reduce the thermal effect on the nozzle we can use a connecting rod. The heat flux for an AISI 304 connecting rod (diameter 1 mm,lenght 40mm, dT=200C) is < 0.1 W.by ingpconci - Let's design something! (I've got an idea ...)
I see the Magnetoshape material, it is a interesting material but I have only some doubt about the temperature effect. If we put the actuator near the nozzle, the temperature can be hight. The piezoelectric actuator has the same problem. Paoloby ingpconci - Let's design something! (I've got an idea ...)
Viktor, I agree, the design of the slider is very challenging. We need to optimize the geometries of the mechanism, it is not easy because the molten polymer fill easily cavity(like in DVD fabrication or in micromolding) Very important is the control of the surface in order to obtain a poor wettability of molten polymer.

The silicon micromachining technology was used in several devices, ink jet printing and other. For example in a StartJet molten metal nozzle chip, where the chip operate at 350C. Ref: Molten Jet Nozzle The thermal conductivity is very good and the silicon MEMS technology can benefit form from the batch fabrication in large arrays.by ingpconci - Let's design something!

Hi , I would like to design and manufacture a variable diameter nozzle as a open source hardware project. The idea is to replicate the mechanism of the four jaw cork compressor. To build the microscopic jaws I use the MEMS technology. In the pictures you can see what we can realize with this top-down technology: "Courtesy Sandia National Laboratories, SUMMiTâ„¢ Technologies, www.sandia.gov/mstc"by ingpconci - Let's design something!

I've installed the aluminium bed support plates and it work very well. I levelled the bed with the screw and now the result are good with the bed leveling test Thanks for theAluminium plateby ingpconci - Ormerod
