Hello my friend, your build looks great. sorry to hear that you have problems getting sound. Printed trumpets are known to be not producing perfect sounds anyway. But your sounds seem extra muffled than the other video in my trumpet page.

According to my experience, the sound in your video very much resembles to the sound I get from my trumpets and cornets when the valves are swapped by mistake or not aligned to their places perfectly.

There are numbers at the bottom part of the valves as 1 2 3 and 1 should be the one closest to the mouthpiece.

If that is the way it is in your assembly, then you may check whether the valves are perfectly aligned to their places.

if these are all ok, then maybe within the pipes and/or u turns there might be some residue support material left. There is a flexible wire sold at the music stores for trumpets. It has brushes in both ends and can be pushed into curving trumpet pipes to puch out anything and brush the inside walls of the pipes. That might be of help too.

I made the valves as snug fits to the instrument body and wanted them to be sanded to match. thinking otherwise there would be an unvaoidable gap and because of this gap and the imperfect finish of 3d printing, a perfect fit wouldn't ever be achieved.

I hope this helps and you get nicer sounds from your instrument.
