3D Printer Layer Resolution vs. Print Size

What are the tradeoffs of large format 3D printers in creating large scale parts when it comes to layer resolution?? While sub 100 micron finishes for high quality can be reached, what else can be done to speed up print times for large parts?? Watch this video with a Development Engineer from 3D Platform to get some tips on size vs. layer resolution. Full Transcript Below …

Narrator:? Talk to me a little bit, Joe, about resolution versus size.? You hear a lot about how fine a print you can get off of a printer, but that?s not always a driving factor.? What?s your experience been?

Joe:? When we have smaller parts like this, we can really push the layer resolution down into the 100 micron range and below.? If you?re really looking for a fine surface finish, these large printers are easily able to achieve those low resolutions.? But when you get into large prints like this, the driving factor is not that I?m concerned about layer resolution.? I really want to get this part into my hands ? get it printed ? so we increase the layer resolution.? That will actually speed up the print and get the part into our hands quicker.

Narrator:? So this part here for example.? You were saying the little one was at 100 micron layer resolution, what would you print something this size at?

Joe:? this would be about a 0.4 or 0.35 layer resolution.

Narrator:? And roughly how long would it take to print something this size?

Joe:? With this part here, once we work on the in-fill, we can get this part down to about a ten hour print.

Narrator:? And if I were to do it at the 100 micron layer resolution, roughly how long would it take for the same size?

Joe:? It?s simple math.? You add it up.? Three times the layer thickness and you will be three times the print time.? It would be somewhere around 30 hours.
