Design with respect to mechanical properties

Post by Milos »

When I receive the result of my first attempt to create spare part for dishwasher, I was not happy with the mechanical properties od resulting body. Thin parts of body are very fragile and I need to redesign this spare part in more stronger shape.
I have two question:
1. Is there any "postproduction" step, that can make the resulting body more stronger? Heating. coating,...?
2. Have you any rule (either accurate or of "thumb") on the design to take into account the fragility of plastics?

TIA

How you are "producing" the part?

Is very different to use a FFF printer or a SLS printer, what material, what "layer height", only to name few of the many variables that could affect strength.

More data are needed.

Prusa 3i MK3 - FFF type production. We have used default production values for PLA and PET-G materials, 0,2mm slit, that program suggested. We let produce the same model with ABS on another FFF printer with the same result (I do not know production data for the time being.)

No other production except FFF was tested. (I have none available.)
