Horn printed 3d

HI,
I bought a drawing of a Yuichi A-290 horn.
I know that the best solution would be to mill it in wood with a CNC, but the cost is very high..
I tried 3D printing them and they don't look bad, but I'm not sure I set good printing parameters.
Can good results be achieved with 3D printing?
I was thinking of trying to print them again, empty inside, with 10 wall shells, and then pouring some plaster inside...
could this be a good idea?
the drivers are jbl 375 and the printer is a bambulab
Thanks and sorry for my English..
 
Thanks for the replies, you are very kind 🙂
I printed them months ago, but I made them with 30% infill and I think something was wrong.
I would like to try to reprint them, it should take 2 days if I use 2 3D printers, otherwise 4 days.
I had thought about chalk, a very dampening material, but if there are suggestions I will gladly accept them.
I bought the project from Joseph Crowe and in the file there are 4 different sized horns with different cuts.
I chose to print at 450Hz, which was sufficient for my 500Hz cutting.
If I were to try to make them out of wood, I would probably make them bigger.
I'll try to look at the link you sent me, although unfortunately I'm not very good at woodworking.
I searched on Aliexpress, they seem very nice, but the shipping prices are very high...

Grazie per le risposte, siete molto gentili 🙂
Li ho stampati mesi fa, ma li ho fatti con il 30% di riempimento e penso che fosse qualcosa di sbagliato.
Vorrei provare a ristamparli, ci dovrebbero volere 2 giorni se uso 2 stampanti 3D, altrimenti 4 giorni.
Avevo pensato al gesso, un materiale molto smorzante, ma se ci sono suggerimenti li accetto volentieri.
Ho comprato il progetto da Joseph Crowe e nel file ci sono 4 trombe di diverse dimensioni con tagli diversi.
Ho scelto di stampare a 450 Hz, che era sufficiente per il mio taglio a 500 Hz.
Se dovessi provare a farli in legno, probabilmente li farei più grandi.
Proverò a guardare il link che mi hai mandato, anche se purtroppo non sono molto bravo a lavorare il legno.
Ho cercato su Aliexpress, sembrano molto carini, ma i prezzi di spedizione sono molto alti...

yes, it is possible to print it with 0 filling,
but I think I made the wrong size of the trumpet..
the one I printed is the 450hz,
and with my 375 driver which is 2 inches with crossover at 500,
I think it's right to print the 300hz with 50x50 troath size...
I attach the link to Joseph Crowe, where I got the project.
Is what I say correct?
Thank you
