Identifying components used in a system

AI Thread Summary
The discussion centers on a university project focused on material deposition systems, specifically analyzing a video showcasing impressive speed and precision. Participants speculate on the technology used, with one suggesting that it resembles FDM 3D printing, where a heated nozzle extrudes filament. However, concerns are raised about the cleanliness of the output and the properties of hot glue, leading to alternative theories. One idea proposes the use of a high-pressure reservoir with a fast rotary valve to achieve the desired results. The conversation highlights the need for further insights into the specific mechanisms behind the system's performance.

Hi,

I am working on a university project looking at material deposition systems. i came across a 30 second video on Youtube and i would be really interested to know how this product is achieving the speed and precision shown in the video. If anybody has any suggestions about the technology used that would be great



Many thanks

Are you aware how FDM 3d printing works?

I'd guess it's just like that i.e. a reel of hot glue filament is pushed through a hot nozzle ('hot head').

To improve speed and precision you increase the power and control system of both the heated nozzle and the stepper motor that pushes the filament.
 
Good thought, Billy, but it makes me wonder. I've never personally seen hot glue come out that cleanly, with no filaments dragging behind. Also, I'm pretty sure that the purpose of the thing is to leave soft glue, which hot glue would not remain. The thing reminds me for all the world of those air-powered BB machine guns in the shooting galleries at a fair. Could it just be a high-pressure reservoir of liquid glue feeding through a very fast rotary valve?
 
Hi all, I have a question. So from the derivation of the Isentropic process relationship PV^gamma = constant, there is a step dW = PdV, which can only be said for quasi-equilibrium (or reversible) processes. As such I believe PV^gamma = constant (and the family of equations) should not be applicable to just adiabatic processes? Ie, it should be applicable only for adiabatic + reversible = isentropic processes? However, I've seen couple of online notes/books, and...
I have an engine that uses a dry sump oiling system. The oil collection pan has three AN fittings to use for scavenging. Two of the fittings are approximately on the same level, the third is about 1/2 to 3/4 inch higher than the other two. The system ran for years with no problem using a three stage pump (one pressure and two scavenge stages). The two scavenge stages were connected at times to any two of the three AN fittings on the tank. Recently I tried an upgrade to a four stage pump...
