Plant Simulation for 3D Printing/Additive Manufacturing

Hello Community,

 

I am wondering if anyone has created a model of an additive manufacturing/3D printing process? I think it's an intriguing idea and I am trying to wrap my head around if there are any obvious pitfalls to modeling such a process or if it can be regarded as a straight forward "discrete MU" process?

 

My main thought it how to handle powder/raw material and how much is consumed by parts 3D printed. Would it be most practical to use the fluid objects/portioner or is it enough to fill a buffer/set a variable to an amount of raw material which is "subtracted" depending on how much is required to produce a specific part? I.e. a fluid -> discrete process, or purely discrete process?

 

Another thought is how to handle the 3D printing machine itself. Can it be simplified to a procTime or are there other parameters to consider (except loading, unloading etc.)? It seems impractical (albeit dynamic) to calculate a proctime from the feed speed of the machine and the part dimensions/volume.. This would also produce the amount of raw material required from the storage, but again it seems complex to calculate this for each part to be produced.

 

Does anyone have any experience in this area and shed some light? I'm trying to brainstorm some ideas.

 

Thank you!

I guess you need to set some priorities.

If you follow the "material flow" idea, the 3D printing is a source. You can easily create a delivery plan. The consumption of material you can trigger by the exit control (if this is not the priority).

If you want to model the occupation of the printer (e.g. based on the "printing speed e.g. in kg/hour") than indeed the portioner could be a good way. You can change the amount of material for the MUs with amountPerMu (e.g. exit control based on a plan).

Hi Steffen,

 

Thank you for your insight.

 

For modeling production line throughput depending on amount of workers + number of printing machines, I guess the occupation of the 3D printer would be necessary to model with the help of the portioner?

 

In a case I am looking at, the occupation of the printer is of interest due to it affecting other things in production, but the consumption of material wouldn't have to be in such great detail. I guess the portioner would be a nice way to get Plant Simulation to automatically handle the consumption of raw material but I am unsure if this way is more complicated than , for instance, manually handling material consumption by decrementing a variable in an entrance/exit control.
