How to Print Objects with a Convex Face

[rraf02 0]

Hi All

I have to print a large face plate, which is basically a the front 1/4" of a box. It is about 145 mm x 218 mm x 16 mm deep. It has tabs and that protrude past the lip.

The front face is convex. The inside of the face plate has mounting posts for a PCB to be screwed down and other devices. I need to verify these alignments and that it fits properly onto the back box.

Based on the protrusions on the back side, I am assuming that I have to print this face down, but that means the convex is against the glass.

What support and adhesion and fill options should I use to print this?

The first print was a dismal failure.

20% fill, I used Touching Plate and Brim it takes about 17 hours to print.

I was going to try a second print with 20% and everywhere, and raft.

Any suggestions or comments?

Thanks

Rob

why don't you print it on it's side? Making sure the convex shape isn't parallel to the glass.

A picture of the model would help as the words do not create an image in my mind.

Convex can work flat but the last bit tends to fail.

However, do not underestimate side printing with a brim - bit to make it work you would normally want to print slow and fairly cool.

Enough infill for strength and no more - perhaps none if you use two or three perimeters.
