Hi! I’m working on my second build. It is being printed in a gradient filament (family’s request). Will it cause problems to reorient some of the parts? I’d like for all of the gradient lines to be going in the same direction (horizontal), but I definitely don’t want to compromise strength of the parts.
If I keep the parts the way they are, the lines will be different for different parts (wings might only show the last color on the oustide-facing piece, seat back center would have vertical lines, etc.). I realize I’ll need to add supports in some cases. But my only real concern is about STRENGTH AND INTEGRITY OF THE PARTS. So I’d love feedback from others who know more about the engineering aspect of these parts.
The family is very into the aesthetics of the chair , so I want to do right by them if at all possible. THANK YOU to anyone who can provide good insight!
I will start this by saying “I am not an engineer/designer so take this with a grain of salt”
For how strong these chairs come out I really dont see there being any issues from changing the orientation other than possible print issues due to more/different supports. There is no way you will get all of the gradiant lines to match perfectly color for color, but I assume you know that already.
I will also say that I am all for trying to do the best I can to give the family’s what they want. But at the end of the day I have to keep that within reason as well.
I would be very curious to see what @MakeGood_Noam thinks about it.
Yep! I get that the lines won’t align. I’m just hoping for the same direction.
My concern stems from a completely different build – I had a part that kept breaking under pressure. When I re-oriented it on the plate (with no other changes), it no longer broke under pressure. So… that’s why I’m a little hesitant to re-orient parts without some engineering input.
Hopefully a more engineering-minded person than either of us will chime in. Thanks!
The thing you need to look out for is if there will be force applied to a part along the same orientation of the layer lines. So if a horizontal force is applied to horizontal layer lines, that part would easily break. Don’t know if that will make sense, but if you Google shear force you might find someone that does a better explanation.
@MakeGood_Noam, thanks for the input. I figured there was a reason for the orientation of parts. Sadly, I don’t have access to an H2; this would have been the perfect orientation but doesn’t work on the P1S. The whole question came up because I printed the wheels first and realized they will all just look purple once assembled due to the gradient being covered by tires. Oh well, I’ll just explain to the family that safety is far more important than looks. Thanks again!
Rainbow filament for Push Handle - if you want the connector to look right you have to flip one of the parts 180 on the X axis. I do the connector on a separate plate.
, so I want to do right by them if at all possible. THANK YOU to anyone who can provide good insight!
